浅谈煤制油工艺中PSA制氢技术应用

Discuss Application of PSA Hydrogen Production Technology in Coal-to-oil Process

煤制油分为煤直接液化和煤间接液化工艺,在整个生产装置运行过程中会使用氢气或者富含氢气的中间气体,而且会产生富含氢气的煤制油尾气,通过PSA(变压吸附)制氢技术把煤制油尾气中的氢气分离出来,重新回到系统中使用。

Coal-to-oil process is divided into direct coal liquefaction and indirect coal liquefaction. Hydrogen or hydrogen-rich intermediate gases will be used throughout the operation of the plant, and it will produce hydrogen-rich coal-to-oil tail gas, the hydrogen in the tail gas of the coal-making oil is separated by the PSA (Pressure Swing Adsorption) hydrogen production technology, return to the system for use.
