PROGECO is a brand of CONVECO Srl products

The BGAK (PpTek technology) BioGas AutoKleen Siloxane Removal System is a filtering system that is fitted in the fuel supply line of a BioGas to Energy plant decontaminating landfill and sewage gas of siloxanes and other VOC`s. It has been designed to filter the siloxanes from the gas automatically switching between twin filter chambers, regenerating the filter medium in the `off-line` chamber. The system is a small skid-mounted self-contained unit and its operation is fully automatic. The siloxane filter units, under normal conditions, will absorb Siloxanes for up to 5 years before the medium requires replacement.

Biogas analysis assists process control and can help to optimise digester operation and maximize methane production. It can also ensure newly installed biogas plant is operating to design specification. PROGECO includes in its scope of supply hand held portable instruments and fixed continuous and automated equipment for analysis of methane (CH4), oxygen (O2), carbon dioxide (CO2), hydrogen sulphyde (H2S) in biogas. Data can be stored or sent to remote PC / SCADA system.

Biogas from anaerobic digestion is saturated with water vapour that has a significant negative impact on the performance of energy recovery units. Removal of moisture is achieved by means of cooling down the biogas flow so that moisture turns into condensate water that can be easily separated, collected and discharged. The system is based on an air-cooled fully automatic water chiller and a water/biogas heat exchanger. The two units are connected by a recirculating water+glicole hydraulic circuit. Condensate water separated in the heat exchanger is collected inside a knock-out drum from which is automatically disposed. The system is designed as package unit; chiller is supplied separately, for installation in non-hazardous area.
