Membrane modules are arranged in parallel banks to achieve required capacity. Because economy of scale is not a factor they are used primarily for small- to medium-capacity hydrogen recovery from refinery and petrochemical offgases. [Pg.91]

Hydrogen is three times more valuable if recovered rather than if used as a fuel [169]. Moreover, hydrogen recovery in a refinery represents a key strategy to meet the increased demand of hydrogen for hydrotreating and hydrocracking. These processes produce a residual gas that contains a... [Pg.837]

Separation of a gas from the gas mixture is a key issue in the various industrial fields hydrogen recovery in petroleum refinery process, oxygen removal to prevent flame, air dehumidification to prevent moisture absorption, dehydration of fine chemical products, for example. Although there are various methods to perform gas separation [membrane separation, pressure swing adsorption (PSA) separation, cryogenic separation], the method using membranes attracts much attention. [Pg.581]

Cryogenic processes using turboexpanders facilitate high levels of ethylene recovery from refinery gas while producing byproducts of hydrogen- and methane-rich gas. In a cryogenic process, most of the ethylene and almost all of the heavier components are liquified and ethylene is separated from this liquid. [Pg.58]
