黄磷企业看好合成气制乙二醇工艺路线,实践证明,电石尾气制乙二醇工艺路线的成功模式对黄磷企业而言具有丰富的借鉴意义,但黄磷尾气净化问题让两者无法联姻。黄磷尾气利用需要脱除氟、砷、磷、硫等杂质。其中氟、砷、硫的脱除有较为成熟的工艺,所以黄磷尾气净化的技术难点是脱磷。目前企业净化黄磷尾气普遍使用的是水洗加碱洗法、变温吸附法和不连续催化氧化法3种方式。但这3种方式在工业化运行中均出现不同的问题:水洗加碱
Phosphorus enterprises are optimistic about the synthetic gas-to-ethylene glycol process route. Practice shows that the successful mode of the ethylene glycol process from carbide exhaust gas has rich referential significance for yellow phosphorus enterprises, but the purification of yellow phosphorus exhaust gas can not marry the two . Yellow phosphorus tail gas needs to remove fluorine, arsenic, phosphorus, sulfur and other impurities. One fluorine, arsenic, sulfur removal of more mature technology, so the technical difficulties of purifying yellow phosphorus tail gas is dephosphorization. Purification of the current corporate yellow phosphorus exhaust commonly used are washing and caustic washing, temperature swing adsorption and discontinuous catalytic oxidation of three ways. However, these three methods all present different problems in industrial operation: washing and caustic
