Background

During the process of producing ethylene and propylene by steam cracking of petroleum fractions, a large amount of C5 and C9 fractions are generated. The C5 petroleum resin is a solid or viscous polymer synthesized by using C5 fraction as raw material and through the action of catalyst or thermal polymerization. The C5 petroleum resin is also called carbon five resin and aliphatic hydrocarbon resin, can be generally divided into 3 types of general type, blending type and primary color transparent type, can be dissolved in various solvents such as acetone, trichloroethane, cyclohexane, toluene, solvent gasoline and the like, has good viscosity increasing property, heat resistance and acid and alkali resistance, and is widely used in tackifying resin of pressure-sensitive adhesive, hot melt adhesive and rubber type adhesive.

At present, the polymerization process of the C5 petroleum resin mainly comprises two processes: thermal polymerization process and catalytic polymerization process. The C5 petroleum resin produced by the method has wide molecular weight distribution, poor transparency, poor photo-thermal stability, large smell, difficult complete dissolution in common solvents, particularly poor photo-thermal stability and large smell, thereby limiting the application field of the resin. The C5 petroleum resin produced by catalytic polymerization of the catalyst has narrow molecular weight distribution, better solubility in solvent and less odor. Therefore, the industry mainly adopts a catalytic polymerization method to produce the C5 petroleum resin, and anhydrous aluminum trichloride is usually selected as a catalyst to carry out polymerization reaction. Since anhydrous aluminum trichloride is hydrolyzed when meeting water and emits a large amount of heat, which leads to permanent inactivation of the catalyst, when anhydrous aluminum trichloride is used as the catalyst for polymerization, a C5 petroleum resin raw material needs to be dehydrated in advance and then enters a polymerization reaction kettle for reaction through a conveying pipeline.

Adopt oil water separating tank to carry out dehydration to the raw materials in this application, send into the feeding after the raw materials accurate measurement and collect the jar and mix, send into oil water separating tank water diversion after the feeding mixing pump mixes, the polymerization cauldron is sent into through the filter to the raw materials after the water diversion, and oily water passes through the pipeline and arranges to the oiliness water pitcher.
