SILOXA FAKA Gas Cleaning System

Transcription

1 1/8 Activated carbon adsorber for removing H 2 S from biogas SILOXA s FAKA gas cleaning systems are highly efficient systems that are available in different versions, with one or two chambers or as a TWIN activated carbon adsorber. With the FAKA activated carbon adsorber, the essential precondition for compliance with the engine manufacturers limit values for combustion gas can be established. It can also be used to ensure compliance with the formaldehyde limit values of the TA Luft (Technical Instructions on Air Quality Control). Depending on the model, the steel adsorber containers are available in stainless steel (1.4301) or with an electrostatically dissipative coating on the inside. The previously heated gas is cleaned by adsorption, using activated carbon that retains the hydrogen sulphide. When the uptake capacity of the activated carbon is reached, the saturated carbon can be emptied into Big Bags, easily and conveniently, through the cone shaped base of the container. Fresh ACO dotiert[s] activated carbon (Big Bags) can then be used to fill the container from the top. A platform with fixed ladder or a work platform with fixed ladder (DIN EN ISO 14122) allows the work to be carried out safely and easily in accordance with the health and safety regulations (FAKA 1500 without platform). Using an H 2 S gas analyzer at the measurement points on the bottom of the FAKA container, it is possible to determine exactly when the used activated carbon needs to be replaced. These sampling points allow the filter uptake status to be measured at any time and at different heights in the activated carbon filter, so that preparations for renewing the activated carbon can be made in good time. Due to the separation of the chambers in the two-chamber (K2) version of the FAKA, it is possible to remove only the saturated carbon from the lower chamber and then replace it with the fresh activated carbon from the upper chamber. This ensures maximum utilisation of the activated carbon in the lower filter chamber and extends the service life of the activated carbon by around 15%. The FAKA two-chamber adsorbers are available in three different sizes, to suit different requirements and applications. In the FAKA activated carbon adsorbers, only high-performance ACO dotiert[s] activated carbon, which has a 50% higher uptake capacity than standard impregnated activated carbon, is used as standard. This reduces the running costs of the system appreciably.

Technical description Features Consumption costs Service FAKA Steel basic features the filter system guarantees long service life of the oxidation catalysts significant lengthening of CHP maintenance intervals prevention of deposits in the combustion chamber high availability of gas utilisation system, operational reliability, low maintenance opportunity for upgrading with further options easy replacement of activated carbon with Big Bags the activated carbon consumption is determined by the H 2 S load and the gas quantity the adsorber is optimised for quick and easy activated carbon replacement, to keep wage costs and downtimes as low as possible large adsorber volumes reduce specific replacement costs because the greater the quantity of activated carbon replaced, the lower the specific costs for transport, wages and downtimes packing of activated carbon in Big Bags reduces transport costs SILOXA offers a full range of services throughout Europe for the operation of gas cleaning systems with activated carbon adsorbers, from delivering the activated carbon to full service. steel construction with electrostatically dissipative coating two gas connections (gas inlet and outlet) DN 150 PN10, FAKA 6000K1 & FAKA 7000K1 DN 200 PN 10 inspection opening DN 500 connecting piece with ball valves for inertisation and taking gas samples shut-off valve for emptying activated carbon DN 150 ladder with cage and platform or work platform with handrail thermal insulating mineral wool 50 mm and aluminium sheet jacket FAKA Stainless Steel stainless steel construction (1.4301) basic features two gas connections (gas inlet and outlet) DN 150 PN10 (FAKA 1500 K1E), otherwise DN 200 PN10 inspection opening DN 500 connecting piece with ball valves for inertisation and taking gas samples shut-off valve for emptying activated carbon DN 150

The required minimum percentage of oxygen depends on the hydrogen sulphide load and can be specified in agreement with Siloxa Engineering AG. The adsorber must be monitored by the opera tor to ensure that it functions properly. Siloxa Engineering AG accepts no liability for damage arising from insufficient monitoring of the adsorber function.
