催化裂化掺炼渣油是提高石油加工深度的一个十分有效的办法。我厂在掺炼管输渣油方面作了大量的工作,掺炼比可达32％以上,并摸索了一整套工业生产数据,为管输油的深度加工取得了一定的经验。但是随着掺炼重油比例增加,催化含硫污水的水质明显变坏,净化度增加,给污水汽提带来困难,影响了全厂的排水合格率。掺炼比从2.5％增加到25％时,硫化物从711mg/L上升到1359 FCC blending residue is to improve the depth of oil processing is a very effective way. I plant a lot of work in mixing pipe residue, blending up to 32% or more, and to explore a set of industrial production data, for the depth of tube oil processing has gained some experience. However, with the increase of blending proportion of heavy oil, the water quality of catalytic sulfur-containing wastewater is significantly deteriorated and the degree of purification is increased, which makes it difficult to strip the wastewater and affects the passing rate of the whole plant. Sulfide increased from 711 mg / L to 1359 when the blending ratio increased from 2.5% to 25%
