The filter family for effective gas cleaning
SILOXA’s FAKA range of activated carbon adsorbers for fine desulphurisation of biogas is a large filter family with 11 members in total. FAKA adsorbers are available with capacities ranging from 1500 to 7000 litres, in versions with one or two chambers, and in the TWIN FAKA version. Depending on the model, the steel adsorber containers are available with an electrostatically dissipative coating on the inside or in a stainless steel version (1.4301).
Fine desulphurisation with the FAKA type activated carbon adsorber removes hydrogen sulphide (H2S) and siloxanes from biogas, sewer gas and landfill gas etc. The removal of hydrogen sulphide is an important prerequisite for compliance with the formaldehyde limit values of TA-Luft (Technical Instructions on Air Quality Control) using a catalytic converter.
All FAKA models function in the same way. The previously dried gas is cleaned in a vertical activated carbon adsorber. The adsorbers are mounted ready for use in a steel structure.
For easy changing of the activated carbon, the bottom of the container is cone-shaped (for emptying) and the top is designed so that it can be refilled with a Big Bag. When the gas is fed in, it always flows through the adsorber chamber from the bottom to the top. The right time to change the used activated carbon can be determined from measuring points in the adsorber (e.g. with an H2S analysis or with periodical manual measurements).
In the twin-chamber versions of FAKA – the K2 models – the separation of the chambers allows 100% usage of the carbon in the lower chamber, risk-free, as the upper chamber acts as a protective filter and prevents breakthrough of the sulphur load. This permits maximum capacity utilisation of the carbon in the lower adsorber chamber at all times, with a clear reduction in operating costs. SILOXA developed this twin-chamber process in 2003 and was the first provider to launch it on the market.
