Product Name: Wet+Dry Type Biogas Desulfurization/Desulphurization Plant Model NO.: ALONG-BIOGAS Biogas Flow Rate: 100~10000 Nm3/Hr H2s Removal Rate: 10000ppm to 20ppm Biogas Utilization: CNG Production Followed: Membrane Separation for CO2 Removal Trademark: ALONG BIOGAS Transport Package: Original Packing Specification: Chemical Solution Origin: China HS Code: 8486909000 Product Description 1, BIOGAS BLOWER. 2,Wet Desulfurization Tower. 3,Rich-liquid Tank.4,Lean-liquid Tank. 5,Regeneration Pump. 6,Regeneration Tank.7, Sulfur Foam Tank. 8,Foam Pump. 9, Filter Press10, Gas-liquid Separator Tank. 11, Desulfurization Pump.12,Dry Desulfurization Tower 13, Dry Desulfurization Tower. 14,Separator TankPROCESSFLOW: GASBoosted by blower, raw biogas inflows wet desulfurization towerfor first-stage H2S removal. After condensate water separation in the solid-liquid separator tank, biogas is delivered into dry desulfurization towerfor second-stage H2S removal, then goes through the separator tankfor dust removal and buffering, to feed the subsequent process. LIQUIDThe chemical solution after first-stage desulfurization process turns into rich liquid, which is stored in the rich-liquid tank, then is pumped into regeneration tankby regeneration pump. The regenerated liquid flows into lean-liquid tankand is pumped by desulfurization pumpinto wet desulfurization tower for re-use. SOLIDThe sulfur solids mixed with liquid is precipitated in regeneration tank, then flows into sulfur foam tank. By foam pump, the sulfur foam is pumped to filter pressfor water separation. And the separated sulfur can be utilized and sold out as by-products.
