Choice for (large scale )biogas upgrading? PWS: Pressurized Water Scrubbing + Low investment and operational cost + Low methane slip 0.8 % + High energy efficiency >96% + Proven technology + No chemicals - Complexity
Choice for small scale biogas upgrading? Importance of •Energy efficiency ? =>Biogas utilization and running hours. •Flow variations ? =>Max flow is 200m3/hr •Available manpower => None •Methane emissions ?
Choice for small scale biogas upgrading? MS: Membrane Separation + Compact + Simple on/off + Cheap + 100% biogas utilization/ flexibility + Highest operational up time + 2 times per year human interaction. + CO2 reuse - High methane slip (conventional)
Why small scale biogas upgrading?>90% of possible biogas production sites are <200m3/hr.60-80% of possible biogas capacity is from small scale site. 50-200Nm3 biogas equals 35-150 l diesel => 170.000-1.450.000 euro/a
Small scale upgrading with membranes CO2Biogas Green gas
Membranes separation J= (k . D . Δp ) / l J= Flux k= Solubility of CO2 in the polymer D= Diffusion coefficient of CO2 through the polymer Δp = The pressure difference over the membrane l = The thickness of the membrane
Biogas:CH4 (53,3%) 35% recycleCO2 (46%) MixerH2O (0,1%) RecycleN2 (0,5%)O2 (0,1%) Stream Membrane Cascade for upgrading Biomethane OFF Gas CH4 > 97% < 0.5% CH4
Choice for (small scale) biogas upgrading? MS: Membrane Separation + Compact + Simple on/off + Cheap + 100% biogas utilization + Highest operational up time + 2 times per year human interaction. + CO2 reuse + Low methane slip ( High selective )
DMT Carborex ® MS+ 0,2 kWh/ Nm3+ 0,3% CH4 slip+ Energy efficiency > 98%+ Operation reliability >98%+ Plug and play+ Containerized+ Low in CAPEX and OPEX- Price linear with membranes
Virtual pipeline• For remote places and low flows (where pipeline are too expensive)• Easy transport and utilization of gas @ 250 bar• Transport of biogas and/ or greengas• Alternative for local use of CBG (mobile CHP/ holiday houses)
