Cases to be considered for catalyst Design The catalyst vendors may predict the yields for following cases: Feed Streams* Case-1 Case-2 Case-3 % wt % wt % Wt LS VGO+BH HS VGO Unconverted oil St run gas oil Annexure E In all the cases vendor should consider the feed rate of 2500 MT/D. Vendor should also predict values at a feed rate of 2000 MT/D. HS VGO will be either form the cold storage or from the CDU-3. We are planning to process LR (Atmospheric and Naphtha with the feed in the future after necessary modification in the unit. Vendor to reformulate the catalyst for the processing of LR and Naphtha when advised by BPCL (MR) Low sulphur VGO normally consists from crude of the following origin: Saharan Blend Mirilight Agbami Seria Light+champion El-Sharara Kikeh Azeri Light Tapis Forcados Champion Yoho Erha Quiboe Mellitah Case-1 feed composition will be considered as the controlling case for the evaluation. However vendor should also predict the yields for remaining two cases. It is expected that this catalyst should also work equally for case-2 (for HS-VGO quality (refer typical feed stock analysis pt 4).

The catalyst properties quoted by the vendor must be in the range as indicated in the fresh catalyst properties... The vendor shall indicate product properties as per point no Vendors have to report Attrition index by ASTM (D-5757) method. If the vendor is adopting different (than ASTM D-5757) method for the Attrition Index, equivalent attrition Index by ASTM D5757 must be provided. If attrition index value as per ASTM D-5757 exceeds more than 5, the catalyst will not be considered for evaluation. Page 8 of 18

9 7.7 Vendor should propose only one catalyst for the unit. Once the proposal is submitted the offered catalyst will not be changed. Offering more than one catalyst will not be considered without any further discussion. 7.8 The Guaranteed yields (as per specific format in Appendix 1) are not to be mentioned in technical bids and shall be furnished along with price bids without any condition. However in technical bid, statement confirming that guaranteed yield pattern quoted in the price bid is considering Typical Feed Proportions specified in Point No. 1 & 4, Unit objectives and Unit Constrains specified in point no 3, typical operating condition as per point no. 5 is to be furnished. The sum total of guaranteed yield must be 100%. In case positive deviation (sum total >100%), the additional quantity over & above 100% will be deducted from the hightest value product and for negative deviation (sum total <100%), the balance quantity will be considered as zero value. (Case -1 yield will be considered as controlling case for evaluation) 7.9 Vendors have to provide Five kg. of representative sample of proposed fresh catalyst.. Vendor should also provide two kg. of representative sample of proposed catalyst after steam deactivation. ASTM Method is to be used for Steam Deactivation. Samples to be clearly identified as Sample of Fresh Catalyst CRFQ No / Sample of Steam De-activated Catalyst CRFQ No as the case may be, and delivered to : DGM (CPO-Refineries), BPCL-Mumbai Refinery, Mahul, Mumbai Samples should reach at the above address within 10 days of tender submission and in any case not later than the tender due date failing which the offer would not be considered for evaluation Fresh Catalyst sample of each vendor will be tested at BPCL R&D, Noida for physiochemical properties and Activity test by ACE unit. as well as performance for predicting yield pattern after doping the catalyst with metals (Ni+V) up to the metal level of 850 ppm (Ni=550 ppm & V=300 ppm approx.) The test results including predicted yields by BPCL R&D will be used for comparison / verification. The physio-chemical properties will also be used for checking with the plant hardware & operating constraints before technical acceptance of the offer. In case of any deviation the vendor will be referred for clarification and only on satisfactory clarification, the bid will be accepted. The test results of BPCL R&D and decision of BPCL based on the said result will be binding on the vendor. Note: ZSM-5 additive addition will be of fresh catalyst addition during PGTR. GSR (Gasoline sulfur reduction) additive may be continued as and when required by BPCL (MR) for gasoline sulfur reduction The Order will be placed for the Catalyst with maximum Net Value Addition (NVA) to the refinery, which will be calculated from the following: Yield guaranteed by vendor; Catalyst addition rate per day 0.60 MT (based on feed rate) Unit thruput per MT/D The order will be placed on the vendor with maximum Net Value Addition (NVA) Page 9 of 18

10 Due to limitation in the hardware, the yields quoted (Guaranteed) as well as obtained during Performance Guarantee Test Run (PGTR) will be rationalized as under at the time of working out the net value addition: a. LPG Yield, more than 25 % wt. shall be considered as dry gas. b. IF LPG yield is less than 20 % wt, then differential yield shall be deducted from Gasoline yield and deducted quantity (wt%) shall be added to dry gas yield. c. The off gas yield will be determined by deducting the interts and C3 s and C4 s. d. C3 s and C4 s in off gas will be treated as LPG yield. The formula that will be applied for net value addition (NVA) calculation will be as follows: [ (Product price Rs per MT * %Wt guaranteed or ASTM corrected, as obtained in PGTR, yields)-feed price Rs/MT] * Daily Thruput (Fresh catalyst landed price, Rs per MT) * catalyst addition rate per day. Note1: In the variable pricing scenario for Fresh Catalyst,, price of catalyst as on date of priced bid opening would be considered for arriving at the catalyst landed price., for calculation of.nva for vendor selection Note 2: NVA calculation for vendor selection (and PGTR) shall be carried out in normal feed Case-1 only, but vendor to confirm the performance w.r.to yield pattern and operating conditions for check cases also in the bid Average product prices for the period April 10 tomar 11 are given below (This is for Information only). Average prices that will be considered for value addition will be last 12 months (latest available at the time of opening of price bid) product prices available at the time of price bid opening. Rs/MT Feed : Gas : LPG : Gasoline(RON 91): Total Cycle Oil : Clarified Oil : Coke : 0 Note: The vendors have to provide yields at corrected gasoline end point of 186 o C and TCO of 95% recovery at 360 o C 7.13 Initial order would be placed only for a Plant Trial Quantity of 125 MT, which will be subjected to Performance Guarantee Test Run (PGTR). Sample from the supplied batch for Plant Trial would be tested at BPCL R&D and the physio chemical properties and MAT/FST activity will be compared with those of the sample offered along with the tender. In case standard FST value of the sample from the supplied batch is lower by more than 5% as compared to that of the tender sample, OR in case the net value addition arrived from guarantee test run is lower by more than 5% of the Net Value Page 10 of 18

11 Addition with the Guaranteed Yield Pattern considered at the time of evaluation of the tender, BPCL would be free to place the order for the next lot on H-2 bidder (on NVA basis), besides the penalty specified in point The FST value result of the fresh catalyst evaluated at BPCL R&D shall be final binding on the vendor During plant trials, performance of the new catalyst will be compared with the Performance of the existing catalyst w.r.t yield pattern, operation and product quality and only if found superior will further procurement be effected Performance Guarantee Test Run( PGTR) : PGTR of first lot shall be conducted jointly in presence of vendor s representative and BPCL (R&D)/Technology. PGTR will be done after addition of 90 MT of fresh catalyst. PGTR shall be conducted for 48 hours. The intimation to vendor for conducting PGTR shall be given 10 days in advance. Unit yield pattern on average basis for 48 hours will be considered for arriving at net value addition. The feed quality during PGTR will be close to the various parameters indicated in Point No. 4. The PGTR yield pattern and actual catalyst consumption during PGTR shall be used for working out the NVA. ZSM-5, GSR additive (whenever required) addition will be continue during the PGTR. Catalyst addition will only be done to make up for normal loss. E-cat withdrawals can be considered to increase catalyst addition rate during PGTR if catalyst loss is less than 0.50 MTPD. Gap and Overlap in product ASTM distillation ranges during PGTR are subject to unit/column limitations and shall be binding on the vendor. For yield comparison of PGTR, corrected yield pattern as per ASTM cut point will be taken as the basis. The ASTM corrected yield pattern will be used for calculating the Net Value Addition. The yield obtained in the PGTR will be rationalized as mentioned in Point no 7.10 (a) to (d), at the time of working out the net value addition If the NVA during PGTR is lower than the NVA calculated with Guaranteed Yield Pattern considered at the time of evaluation of tender by more than 5%, a penalty will be imposed. Penalty will be calculated as under: Penalty in Rupees = {1.0- (Actual NVA/ (Guaranteed NVA) x 0.95) } x Cost of the catalyst in Rupees of total catalyst received at site and in transit at the time of PGTR. (Note: Total cost shall be the landed cost) The above penalty shall be deducted from balance due to the vendor or from the Bank Guarantee. The maximum penalty amount shall not exceed Performance Bank Guarantee amount. In addition to the above penalty, BPCL will also have the option of total rejection of the balance unused catalyst, if any, available in stock, out of the trial order quantity and any Page 11 of 18

12 consignment in transit at the time of PGTR. In the event of BPCL exercising this option, the vendor will have to take back the rejected material at no cost to BPCL PGTR for subsequent batches of catalyst will be done if there is major deviation in Physical & Chemical properties viz. MAT/FST, Particles Size Distribution etc. w.r.to base data and/or actual plant performance 7.17 The catalyst cost is to be based on dry basis after deduction of Loss on Ignition (LOI) quantity. PROCEDURE FOR MEASURING LOI FOR FCC FRESH CATALYST LOI is determined in two stages First stage: 1) By heating the catalyst sample in a furnace from room temperature to 120 C and maintaining for 2 Hrs, cooled in descicator and weighed in a closed balance. The loss in weight is recorded. Experiments are repeated twice for reproducibility. Second Stage: 2) By heating the catalyst sample in a furnace from room temperature to 955 C and mataining for 1 Hr cooled to 120 C and cooled in descicator and weighed in a closed balance. The loss in weight is recorded. Experiments are repeated twice for reproducibility. Result: If the LOI measured in first stage is within +/- 1% range for BPCL R/D and Vendor's results then the LOI to be considered for weight calculation would be Final LOI = (Second stage result - First Stage Result) LOI for each batch of the catalyst shall be tested at BPCL R&D. In case the LOI reported by BPCL R&D is higher than the LOI reported by vendor, the cost implication due to difference in the dry weight of the catalyst lot (due to higher LOI) shall be deducted / recovered from the vendor. Vendor will bill his invoice on the dry weight basis after deducting the LOI quantity as tested by the vendor for that lot. Later, after determination of LOI by BPCL R&D for delivered catalyst, the differential amount for any additional LOI will be deducted / recovered from landed cost. In this regard, BPCL R&D s results shall be final and binding on the vendor. Page 12 of 18

13 For example: Reported by LOI % wt. Wet Weight MT Dry Weight MT Vendor BPCL R&D Delta 1.00 As shown in the example, payment for 1 MT shall be deducted / recovered from the vendor. The price considered for this deduction / recovery shall be landed cost. For determining the LOI, method specified above will be followed The percentage of 0-20 microns catalyst particles shall be as mentioned in Point no. 2. The percentage of 0-20 microns for each batch of the catalyst shall be tested at BPCL R&D. In case the 0-20 microns catalyst particle reported by BPCL R&D exceeds the maximum value of wt% mentioned in Point no. 2, excess will be considered as a loss and the corresponding amount shall be deducted / recovered from the vendor. Price considered for deduction/recovery shall be landed cost. In this regard, BPCL R&D s result shall be final & binding on the vendor During the delivery of catalyst, vendor will bill for the catalyst after deducting the 0-20 micron catalyst quantity in excess of the wt% limit mentioned in Point no.2 For Example: R&D reported 0-20 microns - 3 % wt Dry Weight MT Catalyst considered as loss is = 100 MT x (3-2)/100 = 1.0 MT As shown in the example, payment for 1.0 MT shall be deducted / recovered from the catalyst supplier. The price considered for this deduction / recovery shall be landed cost. Note: If a catalyst lot is subjected to penalty on account of higher LOI, as per clause 7.11 above, then the dry weight arrived on the basis of clause 7.11 shall be applicable in the calculation shown above Payment released by BPCL for each batch supplied shall be adjusted for LOI & particle size loss as described in clause 7.17 and 7.18 above respectively for final settlement. The differential amount, if any, shall have to be made by vendor through DD or Banker s cheque to BPCL. Alternatively deduction shall be made from Bank Guarantee for recovery of such amount.
