Innovative optimised Pressure Swing Adsorption (PSA) technology looks set to deliver operators of waste or sewage plants with significant operational and financial advantages.
ETW Energietechnik GmbH has successfully improved and optimized the PSA technology, recognized for decades as an effective and feasible process for biogas upgrading in different large scale industrial applications.
The German company has developed the SmartCycle PSA to upgrade biogas to RNG 80,000 hours on-stream time, more than 99 percent availability and purity.
The new Biogas upgrading technology has been developed by a team of adsorption specialists with many years of experience in the chemical industry, highly qualified plant builders and mechanical engineers. That’s how the SmartCycle PSA was born. The Biogas upgrading system developed by ETW is designed to deliver very long equipment lifetimes.
The SmartCycle PSA extremely low energy consumption of 0.14 KWh/Nm³ - represents a major step in innovation with large economic benefits. The optimized pressure swing process makes it possible to use an innovative dry, low maintenance compressor technology with a very high availability.
The biomethane plant designed by ETW can automatically adjusts the pressure swing cycles to a varying inlet gas quality and volume flow, enabling the operator to have total control over outlet gas purity (over 99%) or the desired heating value.
The company says the innovative process control system will delivers operators of waste or sewage plants dealing with constantly changing biogas qualities and flows, or operators who want to shift spontaneously between the electricity and/or RNG markets to maximize income, with significant operational and financial advantages.
No consumables other than electricity are required, resulting in extremely low operating costs in any operational situation.
ETW have already built four large-scale SmartCycle PSA plants with an documented overall onstream time of more than 80,000 hours and 99 percent availability - interested operators can check out the performance of the plants in different biomethane production sites across Germany.
ETW will present the innovative biogas upgrading technology at the Energy Decentral Fair taking place from 15th to 18th November in Hannover, Germany.
ETW Energietechnik GmbH has been developing and producing energy plants in Moers, Germany, since 1997. The company‘s core business comprises the construction and maintenance of combined heat and power (CHP) plants in the output range of 400 to 4,600 kWel, together with highly efficient biogas upgrading plants that produce pure biomethane out of raw biogas using a high-end PSA technology.
The company is a one-stop provider: from the transfer of biogas to the feed- in of power into the grid and the provision of heat, ETW also takes care of the construction, commissioning, and maintenance of CHP and biogas upgrading plants.
