襄樊襄州区代理壳牌液压油-空压机油产品溶剂脱蜡工艺主要包括结晶、过滤、溶剂回收和冷冻四部分，其目的是除去油品中的石蜡，油基础油的倾点。该工艺在加工较轻的原料时有技术优势，脱蜡油收率高、粘度指数较高。为了能耗、节省操作费用、投资，油基础油生产企业都采用溶剂脱蜡和蜡脱油联合工艺，近几年主要是在节能、油和蜡收率等技术方面有比较大的改进。 （3）白土补充精制。白土补充精制是使油与白土在一定温度下充分混合，利用活性白土表面的吸附性能，通过加热、蒸发、过滤等工序，将油中的氮化物、胶质、沥青质、环烷酸皂、不饱和烃、选择性溶剂、水分、机械杂质等除去，从而油品颜色、残炭、油品的抗氧化安定性和抗乳化度。Solvent Dewaxing process mainly includes crystallization, filtration, solvent recovery and freezing four parts, its aim is to remove the wax in oil, oil-based oil pour point. The process has advantages in processing lighter feedstock, higher dewaxing oil yield and higher viscosity index. In order to save energy, Operation Cost and investment, the combined process of solvent dewaxing and wax deoiling is adopted by the oil base oil production enterprises, in recent years, there have been great improvements in energy saving, oil and wax yield technologies. (3) the clay is added and refined. Clay refining is to make oil and clay fully mixed at a certain temperature, using the adsorption properties of activated clay surface, through heating, evaporation, filtration and other processes, removal of Nitride, gum, asphaltene, naphthenic acid soap, unsaturated hydrocarbons, selective solvents, moisture, mechanical impurities, etc. , thus oil color, carbon residue, oil antioxidant stability and anti-emulsifying degree.
