Info

Project Optimization•H2S– May or may not require treatment.– Can treat on tail gas stream (preferred) or feed stream– Options:• No Treatment, Digester Additives, Biological Treatment,Sulfatreat / Iron Sponge, Liquid Redox• Tail Gas Disposal– Enclosed thermal oxidizer if design for high methane recovery– Digester heating possible with combustion of tail gas.– Recovery of heat from compression or flare. Generally expensiveand limited to larger flows• Required Pipeline Pressure– High pressure requires additional compressor
