Jinan Biogas Purification Project site Grid-connected
Shandong · Jinan | BOO Model | MSW leachate biogas

Jinan Biogas Purification Project (Shandong)

10,000Nm³/dayBiogas Processing Capacity
96%+CH₄ Purity
PSACO₂ removal process

Feedstock is biogas from MSW leachate anaerobic fermentation. Front-endwet complexed iron + dry iron oxideTwo-stage desulfurization reduces H₂S from >1,000 mg/Nm³ raw gas to trace ppm; back-endPressure Swing Adsorption (PSA) CO₂ removalCompletes CH₄ enrichment. Purified gas is injected via medium-pressure metering skid into the municipal gas pipeline as supplementary fuel for residential and industrial use.

Weihai Biogas Purification Project (Shandong)

30,000Nm³/dayBiogas Processing Capacity
96%+CH₄ Purity
HPWSwater scrubbing

Feedstock is biogas from large-scale livestock farm manure anaerobic fermentation. alkaline biological desulfurizationLeverages biological oxidation mechanism — low operating cost; Water Scrubbing (HPWS) CO₂ removalLeverages the solubility difference of CH₄ vs CO₂ in water for separation, while simultaneously deep-removing residual H₂S and NH₃. Forms a closed loop: "manure → biogas → biomethane → long-term grid supply contract."
