environmental impact of oil refining
石油炼制中的环境影响(e nvironmental im-pact of 011 refining)石油炼制过程中排出的大量废水、废气、废渣以及生产车间发出的噪声都对环境产生污染，需认真治理。 炼油污水炼油过程中，石油中所含少量硫、氧、氮等转化为有害化合物溶解于水中，造成污水，其来源和成分见表。 炼油污水的排放量很大。20世纪80年代，中国炼油厂每吨油排放污水为3~4t。日本炼油厂每立方米原油排放污水为0.2一0.3m“。所以各国都加强研究，炼油污水来源及其成分 工艺过程原油脱盐常减压蒸馏催化裂化、热裂化减粘、延迟焦化加氢裂化催化重整加氢精制轻质油酸碱精制溶剂脱沥青 污水主要成分_油、硫化物·酚类硫化氢、氨、酚、油酚类、硫酚、硫化氢、氨、氰化物硫化氢、氨、酚类-高浓度硫化氢、氨、酚类硫化物硫化氢、少量酚和~油含酚的酸水层和含酚、硫化氢的水层少量硫化物、油和氨以尽量减少污水排放。前苏联建成过炼抽厂供水排水闭路循环系统埃现了“零排放”·一_炼油废气炼油厂废气中的主要污染物为二氧化硫(S():称硫化氢(H:s)、氮氧北物(NO刀、一氧化碳(co)、烃类化合物及粉尘。这些废气很多散发恶臭，毒害人体，污染环境。:_一炼油废渣炼油厂生产和精炼油品所使用的化学药剂、工艺反应过程中所用的催化剂及精一制用的吸附剂等，在反应后产生化学废渣。主要是酸渣、碱渣、白土渣等。还有污水处理过程中产生的污泥。其中，化学废清毒性大、易反应，较难处理。这些废渣可通过大气、水体、土壤直接或间接地污染环境。· 炼油厂噪声炼油厂噪声源有加热炉、电动机、压缩机、风机(催化裂化主风机、大型风机派空气冷却器、管线阀门、气体或蒸气放空口、火炬等。这些噪声声级高达%~105dB(A)。它们均对环境造成污染。可通过加装消声器、设置隔噪围墙等措施_降噪。 (阎鸿炳李滇林)
