ANALYSIS AND TREATMENT MEASURES FOR THE INCREASE OF PACKING LAYER PRESSURE DIFFERENCE IN CDAlky? ALKYLATION REACTOR
Alkylation technology is an important oil processing technology for producing clean fuels,which usually adopts sulfuric acid alkylation of CDAlky® static mixing reactor technology.However,there are still some problems in the process of sulphuric acid alkylation,for example,the increase of the pressure difference of the packed bed in the reactor leads to the decrease of the operating load of the unit,which seriously affects the production capacity of the unit.In view of this problem,the factors which might affect the increase of the pressure difference of the packing layer were investigated from four aspects:the initial pressure difference of the packing layer,the impurity content in raw materials,the precision of the circulating acid filter and the impurity content in the machine-sealed white oil.The treatment measures were put forward accordingly,which could effectively solve the problem of the increasing pressure difference of CDAlky® alkylated packing layer,and provide technical reference for other units.
