6 1. About the device 1.1. Description The series 3400 Cooking TCU is designed for alkali concentration measurement in pulp mills, based on electrical conductivity and temperature using Valmet 4-electrode conductivity sensors series lt is designed for wall mounting or panel mounting in industrial plant environments. The TCU has four set-up modes. Each of the four set-up modes has access to individual settings of temperature compensation, output range, alarm, and calibration. The set-up modes are selectable remotely or from the keypad. The TCU has two 4 20 ma current outputs, a display, and a keypad. The line-powered version has two relays for alarms. HART protocol for field device transmitters is included as standard feature. TCU versions, type no. Wall mounted Panel mounted Loop powered 3407H 3408H Line powered 3417H 3418H 1.3. Temperature compensation ln an electrolyte, all ions present will contribute to the conductivity. Different ions will contribute with different amounts and the amounts will vary with temperature. When the conductivity is used for the calculation of a chemical concentration, it is necessary to calculate what the conductivity would be at a fixed temperature (the conductivity is temperature compensated). This conductivity is calculated from measured conductivity and temperature. As different ions have different temperature dependences, the temperature compensation is to be selected to fit the actual application. The temperature is measured with a Pt-1000 resistor in the sensor Applications The type 3400 Cooking TCU is designed for applications in the pulp industry. The values to do the signal conditioning for each application are stored under a recipe No. The values control the measuring range, the temperature compensation, the linearization, the expansion, and the conversion to engineering units. See Technical specification for the recipes Sensors Sensors are based on the 4-electrode principle according to which the current and the voltage are measured across separate electrodes. That eliminates the errors from the polarization effect that is generally a problem at high conductivities. The value of the cell constant is stored in the sensor. This makes all sensors interchangeable without sacrificing accuracy and without the need for recalibration or re-entering the cell-constant when exchanging the sensor. A large selection of sensor types is available meeting the needs for almost any application. Conductivity TCU series Installation & operating manual K14927 V1.1 EN

7 2. Installation 2.1. Installation notes Important issues when planning TCU installation: Whether mounted on a wall, in a panel or onto a piping or cable tray, the place should be free of vibrations and mechanically shocks should not occur. Protect the instrument from process electrolyte, and from downpour. lf necessary use a Protection Shield. Protect the instrument from excessively high or low temperatures and from direct sunlight. Be aware of the sensors requirements for liquor volume around the sensor tip. Minimize the length of sensor cable as much as possible. Mount the sensor at a place where it is protected from mechanical impact, where it can be accessed and extracted from the process liquor for service jobs, and where the process liquor is properly grounded via the process piping. Look out for ground loop currents, which can cause a fluctuating or faulty reading. There should be no potential between the mounting place of the TCU case and the sensor. lf mounting the TCU on a cable tray, the cable tree should be electrically connected to the process piping. Also, look up for a potential difference between the protective ground and the process piping and/or the mounting place of the TCU. A special situation arises where the process piping is made by isolating material e.g. PTFE lined steel piping, PVC or PP piping, giving no ground connection of the process electrolyte. lf the sensor is of the type where no metal structure is in electrical contact with the process electrolyte giving a grounding of the process electrolyte that way, it is necessary to establish a grounding electrode in the process electrolyte, which must be connected to the metal structure of the sensor or to the housing of the TCU Dimensions Ø5.2 5 esc OK 26.5 Fig. 1.

11 2.6. Mounting the sensor The sensor should be mounted at a place where there will be no occurrence of air pockets or bubbles. The best installation is obtained across a pump or in an upstream pipe. lf the installation is made in a downstream pipe, it may be necessary to insert a flow damper just after the measuring place. Recommendation: Install stop s so that the sensor can be removed for service. If stop s are used for regulation of the flow, the outflow shall be the most closed of the s in order to create an excess pressure in the measuring chamber. When measuring on lye containing chips, which may accumulate in the measuring chamber, the inlet has to be done through a filter. A choked measuring chamber will cause a scaling alarm, even if the scaling on the sensors is very little. When white liquor is added to the cooking liquor, it should preferably be done before a pump or a mixer. The pump will mix the liquors, thus measurements done at the pressure side of the pump will include the added white liquor. Stop Stop Up Blow Samle Sensor Fig. 8.

18 4. System testing & adjustment 4.1. Verifying system operation After installation it is recommended to verify the TCU operation. lf the TCU is mounted in a by-pass line it shall be verified that the liquor in the by-pass line is the same as the liquor in the main line. Black liquor, white liquor, and green liquor normally have a temperature close to or above 100oC. lf the flow in the sample line is too small, the temperature will be below normal process temperature. One of the alarms can be programmed to warn for this situation. From factory the Valmet TCU system has been setup according to the specifications of the purchase order and the sensor is adjusted in the relevant liquid. No calibration is needed before installation, since the default calibration line is already present in the TCU. The TCU determines the concentration based on conductivity and temperature. Deviations from mill laboratory analyses of the liquor may occur for various reasons. After installation it is recommended to verify the TCU operation by comparing TCU readings with laboratory results. We recommend using at least 10 readings taken over several days (it is recommended that you use the "Application Evaluation form" to keep track of these readings). These readings must cover the concentration range of the TCU as far as possible. Example: Application Continuous cooking process (Trim). TCU reading 5 units 13 units 15.3 units 15.8 units 21.7 units 32.6 units 10 units 19.7 units 24.2 units 29.8 units Lab. values, as EA 8.5 g NaOH/l 17.3 g NaOH/l 19.8 g NaOH/l 12 g NaOH/l, disregarded 26.9 g NaOH/l 38.7 g NaOH/l 13 g NaOH/l 23.6 g NaOH/l 29.6 g NaOH/l 35 g NaOH/l The readings shall be plotted in a X-Y diagram to show how well they correlate, whether the sensitivity is correct, and whether there is an offset. When evaluating the results the accuracy of the laboratory tests should be taken in account. lf the correlation between the laboratory results and the TCU readings is low, the installation shall be checked. Especially it shall be considered if air bubbles can occur and if the sensor tip is constantly surrounded by liquid. lt may also be helpful to check the working procedure in the laboratory. lf the correlation is satisfying but there is a slope error and/or an offset error, the calibration line can be changed. See section 3.6. Valmet has prepared a spreadsheet (MS-Excel) with guidelines to help with the fore mentioned task which can be obtained from the download section of our website at (ref. No XLS).

19 4.2. Titration of black liquor When taking samples of black liquor, the following guidelines should be observed: The sample should be close to the sensor. The sample pipe should be flushed before collecting samples. Take a 5 10 liter sample of black liquor over a period of 1 minute. At the same time make a reading of the TCU average value. Stir the sample and make a new 500 ml sample from the previous one. Filtrate the new sample. The procedure in the following is known as the Karin Wilson method. When titrating for determining EA and AA, the Na 2 CO 3 as well as the neutralized hydroxy acids might interfere. To avoid that Na 2 CO 3 and some of the neutralized hydroxy acids (NHA) are precipitated by adding Ba++. Using a suitable dilution during the titration, the EA will be titrated already at ph = 11 with practically no influence from the non-precipitated NHA The titration is continued to ph = 9 thus all the NHA which may interfere above ph = 9 are titrated. Now the remaining Na 2 S is converted to a strong base by adding formalin (ph rises). Finally, the titration is performed to ph = 9 for determination of AA. Equipment: 200 ml beaker 20 ml pipette 50 ml burette ph meter Magnetic stirrer Reagents: Barium chloride solution, 200 g/l BaCl 2, H 2 O pro liter Hydrochloric acid 1.0 M HCl Formaldehyde 40% neutralized by NaOH to a faint pink colour using phenolphthalein indicator Procedure: 1. Pour 50 ml distilled water and 30 ml of barium chloride solution in the 200 ml beaker. 2. Pipette 20 ml of filtered black liquor into the beaker. 3. Titrate potentiometrically with 1 M HCl until ph = 11.0 (A ml). 4. Continue the titration to ph = 9.0 (B ml). 5. Add 5 ml formaldehyde, wait for 30 seconds and continue the titration until ph = 9.0 is reached once more (C ml). Calculations: Effective cooking (NaOH + 1/2 Na 2 S) = 2 * A g/l as NaOH (= * A g/l as Na 2 O) Active cooking (NaOH + Na 2 S) = 2 * (A B + C) g/l as NaOH (= * (A B + C) g/l as Na 2 O) Sodium hydroxide (NaOH) = 2 * (A + B C) g/l as NaOH (= * (A + B C) g/l as Na 2 O) Sodium sulphide (Na 2 S) = 4 * (C B) g/l as NaOH (= * (C B) g/l as Na 2 O) Example: A=10.0 ml B = 13.0 ml C = 15.0 ml EA= 20.0 g/l AA= 24 g/l NaOH = 16 g/l Na 2 S = 8 g/l as NaOH Conductivity TCU series Installation & operating manual K14927 V1.1 EN

20 4.3. Adjusting for concentration Calibration is the procedure of entering new endpoints for the low and high end of the basic TCU range. This is done from the menu points Adjust lo and Adjust hi. lf no calibration has ever been done since the application was selected, the Adjust lo will have a value equal to the low endpoint, and the Adjust hi a value equal to the high endpoint, of the basic TCU range. Selecting an application, or reselecting the actual application, will overwrite any adjustments with the default values. Adjusting procedure: 1. Grab samples from the process stream and read simultaneous display readings of the TCU. 2. Analyze the sample in the laboratory to get chemical values. 3. Read the actual value of Adjust lo and Adjust hi. 4. Plot the Laboratory values (y) versus the TCU readings (x). 5. Calculate the linear regression line. 6. Calculate (or read from the graph) the estimated laboratory values corresponding to the actual value of Adjust lo and Adjust hi. 7. Go to the menu point Adjust lo and Adjust hi and enter the estimated values Changing the chemical value unit The alkali concentration is often expressed in different units. Common units are: Unit g/l NaOH g/l Na 2 O g/dl Na 2 O lb/ft 3 Na 2 O lb/gal Factor A recipe in g/l NaOH can be converted to another unit by dividing the limits with Factor and changing the unit text g/l NaOH corresponds to lb/ft 3 Na 2 O. "Adjust hi" must be changed from 120 to 5.8, Unit1 changed fro, "g/l" to "lb/ft3" and Unit2 changed from "NaOH" to "Na2O". Also the Alarm setting and ma output must be changed to the new unit. Example: Application (20-40 % NaOH). Since no adjustment has previously been done, the actual value of "Adjust lo" was found to be 20, and actual value of "Adjust hi" was found to be 40 Assume the following data are collected: TCU reading (x) 24.0 g/l 27.7 g/l 30.9 g/l 29.2 g/l 32.3 g/l Lab. values (y) 26.3 g/l 28.9 g/l 32.1 g/l 31.0 g/l 33.6 g/l Adjusting hi New values Adjusting lo Lab. values Adjusting lo Regression line Old values Fig. 2. Adjusting for concentration. Adjusting hi TCU reading Linear regression gives the equation: y = * By entering 20 resp. 40 for x in the formula, the new low-end and high-end values are obtained: Adjusting lo (x=20) Adjusting hi (x=40) Conductivity TCU series Installation & operating manual K14927 V1.1 EN

21 5. Maintenance & troubleshooting 5.1. Cleaning the sensor Cleaning may be necessary if deposits have built up to an extent that affects the cell constant of the electrode part. When cleaning the sensor do not use hard material to scrape or grind. Use a soft brush or cloth and a suitable cleaning remedy depending on the nature of the deposits. Be careful not to damage the electrodes as this might affect the accuracy of the sensor. Chemical cleaning can be applied by using any reagent that will not affect the sensor material. Sulphamic acid (NH 2 SO 3 H) is recommended. Use 250 g in 1 litre of water. Heat the water to ease dissolving. The solution can be used cold or warm. List of usable cleaning acids for sensors. Insert for max. 2h at 30 C~ 86 F Acetic acid CH 3 COOH Citric acid C 3 H 4 (OH) (COOH) 3 Formic acid HCOOH Lactic acid C 3 H 4 (OH) COOH Nitric acid HNO 3 Oxalic acid (COOH) 2, max. 40% w/w Phosphoric acid H 3 PO 4 Sulphamic acid NH 2 SO 3 H Sulphuric acid H 2 SO 4, max. 30% w/w Tartaric acid C 2 H 2 (OH) 2 (COOH) 2 Cleaning procedure: 1. lmmerse the sensor into the sulphamic acid and let stay for 5 minutes. The entire thick part of the sensor tip should be immersed in the acid. 2. Remove the remaining scaling using a soft brush. lt is important to remove the scaling where the electrodes and the PTFE meet. 3. Repeat 1 and 2 if not clean. PTFE should appear white and intact. Electrodes should appear clean with a smooth metallic surface. 4. Also clean the sensor shaft all the way up. The shaft does not need to appear with a smooth metallic surface, but the scaling should be removed to prevent building up thick layers, which in the long run will destroy the packing system when passing during the sensor withdrawal. WARNING: Do not use Hydrochloric acid (HCl) or Hydrofluoric acid (HF)! Fig. 1. Cleaning the sensor in acid. Conductivity TCU series Installation & operating manual K14927 V1.1 EN

22 5.2. Troubleshooting Locate the problem to the monitor, the sensor, sensor installation or to the electrical connections. If possible shift to another sensor or use a test probe to check the TCU. If the temperature reading is very wrong: Check Pt1000 in sensor for short circuit or interruption. The check can be done by resistance measurement from the sensor connector. Temperature reading partly wrong: This error may arise from a poor thermal contact of the Pt1000 element to the sensor structure. The thermal contact can be checked by measuring the response time for a temperature change. Another source of error may be the installation. The steel part of the sensor with the reduced diameter is to be fully inserted in the process liquor flow. Conductivity/process value far out of range: Check the sensor cable for damage and check the sensor cable connection in the monitor for broken wires. Is the sensor tip surrounded with process liquor? Check the measuring section of the sensor for scaling deposits and for electrode damage. No reading in display: Check line voltage, fuses and check that the connectors are in place. Setting of the temperature compensation. Setting of analog output and accordance to setting of analog input of DCS. Make a record of set-up info. If help is required from factory please make a record of the measurement display and the service display. This can be done with photos. Use backlight if possible or illuminate the display from up or down in a 45 angle to avoid reflections (Fig. 2). Do not use flash Plug-up of measuring chamber lf the TCU is used for liquor measurements in a bypass, using a measuring chamber, the line or the measuring chamber may get plugged up, causing nonsensical TCU readings. Black liquor, white liquor and green liquor normally have rather stable temperatures close to or above 100 C. lf the liquor flow for some reason stops, the consequence is that the temperature will drop below the normal process temperature approaching the ambient temperature by time. Programming one of the alarms as a minimum alarm assigned to the temperature and with an alarm point a few degrees below the normal operating temperature range can be used to warn for partial or total stop of the liquor flow Checking flow rate in measuring chamber Checking the flow rate can be based on the time delay of a step change of either temperature or conductivity of the liquor. lf the temperature is used, the flow must be stopped on the inlet side until the chamber and piping are cooled sufficiently. Then the inlet should be opened as fast as possible and the time to 90% of the final temperature step is reached should be measured. Since the 90% time of the temperature sensor is approx. 30 sec. the above 90% time for the final temperature step should be no more than 1 minute. Adjusted in this way the flow is assumed to be litres per minute, which is considered sufficiently high to flush the chamber, to keep the sensor clean, and to secure a fast response of the signal. lf the piping on the inlet side is long, additional time can be accepted, e.g. 5-6 sec. per metres of the piping. lf the temperature drop compared to fully open s is more than C, insulating the piping and chamber should be considered.

Product Overview The TCU is based on 4-electrode conductivity and temperature measurement. Each TCU has four set-up modes, each holding a separate set of temperature compensation or concentration recipe, output setting, alarm setting etc. The set-up mode can be selected from the TCU keyboard, from digital input, or from a device-specific command.

37 Valmet TCU series 3000 rev. 3 HART Field Device Specification 4. Product Interfaces 4.1 Process Interface The TCU is designed to be used with series 4100, 4200 and 4300 conductivity sensors. Sensor connections are documented in the TCU manual. 4.2 Host interface Analog outputs 4 20 ma The TCU has two 4 20 ma outputs called ma1 and ma2 where ma1 carries the HART signal. The capacitance number CN = 1.5. The ma outputs are isolated from measuring circuit and power supply. In the loop-powered TCU the outputs are isolated from each other whereas they share a common return in the line-powered TCU. The outputs are not used for indication of malfunction or alarm status. The user can select the variable and its range for each analogue output. See specific TCU manual. Usually PV (temperature compensated conductivity or concentration) is put on ma1, and SV (temperature) is put on ma2.
