General
■ The Process for Biogas Upgrading
The SGI -PSA process for upgra-ding of raw biogas to bio natu-ral gas quality applies a Vacuum regenerated Pressure Swing Adsorption (PSA) tech-nology. CO2, higher CxHy,H2S, odours and other undesired components will be simulta-neously removed by activated carbon and carbon molecular sieves. A methane purity of >96%Vol as well as methane recoveries of 98% can be achieved. The SGI - PSA CO2 removal plants are providing low-cost bio natural gas with a reliable, flexible and trouble free process. SGI - PSA systems and machinery components for feed gas compression and vacuum generation are suc-cessfully employed for the bulk
removal of CO2 from various raw gases. The useful capaci-ties range from several 100 Nm3/h bio natural gas product up to several 1000 Nm3/h.
Special Features
Particular features of SGI's PSA process and machinery com-ponents are high CH4 recove-ry rates, low operating and maintenance costs and ope-rational simplicity. Extensive know-how and engineering expertise guarantee the design and construction of tailor-made and economical plants of the highest quality. Modular, containerized design of the CO2 removal plants reduces erection time and costs at site. The fully prefabri-cated machinery containers are thoroughly tested before they leave SGI's workshop.

SGI - Machinery Container
SGI - Biogas - PSA and Multi Stage Machinery Container for:
■Biogas - PSA
■Dry and oil-free gas com-pression and evacuation
Advantage of machine con-tainer installation
■No need for a special machine foundation, only a concrete base plate is required for the machine container
■No need for a noise pro- tected and ventilated machine house or building
■ The PSA and the machine- ry is completely installed and piped in the machine container
■ The machines are installed inside the container on flexible machine elements so that no dynamic machi- ne forces are transferred to the concrete base plate
■Wiring of PSA machines and instrumentation to a terminal box inside the machine container
■Noise protection of the machine container wall down to 80 dB(A)pressure sound level in 1 m distance from outside container wall
■Ventilation inside the con- tainer to transfer the radiated machine heat via the ventilation air outside
the container including inlet and outlet noise elimi- nation houses
■ Short installation time because PSA and machi- nery inside container is completely mounted, piped, instrumented, wired and tested.
