在挪威 Statoil公司的 Mongstad炼油厂所做的试验中 ,一种用于从工艺尾气吸收硫化氢的气体 -溶剂并流接触器可在总停留时间仅 1秒内 ,将硫化氢脱除到可接受的 2 5 ppm水平 ,而炼油厂标准的逆流吸收器停留时间需要 40秒。试验采用二异丙醇胺( DIPA)。该接触器由 Framo净化公司 (
In a test conducted at Statoil’s Mongstad refinery in Norway, a gas-solvent contactor for the absorption of hydrogen sulphide from the process tail gas can be used to remove hydrogen sulfide to acceptable levels for a total residence time of only 1 second Of the 25 ppm level, while the refiner’s standard countercurrent absorber residence time takes 40 seconds. The experiment used diisopropanolamine (DIPA). The contactor by the Framo purification company (
