FLUID PURIFICATION

摘要

Fluid purification A flowing fluid is purified by contacting with a solid absorbent in a physical form (such as webbed rings or foraminate metal sheets) having a geometric surface area per unit pressure drop of at least 0.1 in S.I units. Examples of fluids treated are (a) a mixture of CO with steam to be reacted over a coppercontaining catalyst and (b) a naphtha or LPG hydrocarbon following hydrogenation to convert sulphur compounds to H2S and halogen compounds to hydracid.
