hot gas purification
hot gas purification 双语例句
The occurrence of acetylene, from raw materials to the precision of the filling acetylene bottle, after three purification, drying, such as three-tier multi-channel processes, apart from effective to hydrogen sulfide, phosphine, water and other harmful impurities, so that the purity of acetylene gas as high as more than 99% of the acetylene gas to avoid phosphorus, sulfur impurities in the welding and cutting operations transferred to the molten metal in the Department caused by deterioration of weld quality, weld porosity occur, resulting in cold or hot brittle brittle and other undesirable phenomena.
从原料乙炔的发生到精乙炔的充瓶，经过了三级净化、三级干燥等多道工序，有效去除了硫化氢、磷化氢、水份等多种有害杂质，使乙炔气体的纯度高达99%以上，避免了乙炔气中磷、硫杂质在焊割作业时转移到熔融处的金属中而引起的焊缝质量变差、出现焊接气孔、产生冷脆或热脆等不良现象。
The characters of the Rectisol process are as follows: good absorbency, high gas purification degree, carbon dioxide can be removed from export gas by 10-20ppm, and the inorganic and carbon oxysulfide can be cleaned by less than 0.1 ppm; as a absorbent, the methanol can be acquired easily, and it is very cheap; its selectivity is good, and the solubility of carbon dioxide, sulfureted hydrogen and carbon oxysulfide is very big, but the solubility of hydrogen, carbon monoxide and methane is very small; the temperature of boiling point is low, and its hot regeneration temperature is low, and the enemy of consumption is also low.
低温甲醇洗法的特点：吸收能力大，气体净化度高，出口气中二氧化碳可脱除至10-20ppm；作为吸收剂的甲醇易得，价格低廉；选择性好，甲醇对CO_2、H_2S、COS的溶解度大，但对H_2、CO、CH_4的溶解度小；沸点低，它的热再生温度低，能耗低。
