摘要
介绍了现代煤化工中的2种工艺——直接液化与间接液化的异同点。通过对现代煤化工中的煤液化工艺的分析,提出了在该类装置上使用的阀门的选择要求,还从材料、工艺、抗腐蚀、结构及耐磨特性等方面进行了分析,以期能够为煤化工企业及阀门制造企业提供参考。
The differences and similarities between two process was introduced ,which is direct liquefaction and indirect liquefaction in the modern coal-to-chemicals. Through the analysis of coal liquefaction process in the modern coal-to-chemicals, proposed requirements of valve selection which is be used to this kind of device. In order to provide references for coal-to-chemicals enterprises and valve manufacturing enterprise, the material, process, corrosion resistance, structure ,wear resistance and more also be analyzed.
