Abstract

A dechlorination method and an apparatus suitable for C5 petroleum resin hydrogenation process. According to the method, a dechlorination reactor filled with a high temperature solid dechlorinating agent is placed at the downstream of a C5 petroleum resin hydrogenation reactor; a gas-liquid two-phase product containing hydrogen chloride at the outlet of the hydrogenation reactor directly enters the dechlorination reactor; and through a reaction, hydrogen chloride generated during the hydrogenation process is removed. Through the above technological method, dechlorination of a hydrogenation product is realized. thus, the technology of the invention replaces general gas-liquid two-phase alkali washing and washing dechlorination technologies in current C5 petroleum resin hydrogenation process. Through the method and the apparatus, the dechlorination effect of hydrogenation reaction discharge can be improved. Further, the C5 petroleum resin hydrogenation technological flow is simplified, corrosion of system equipment and quality requirements of materials are reduced, and equipment number of the C5 petroleum resin hydrogenation apparatus is decreased. The apparatus and the method provided by the invention are beneficial to reduction of equipment investment and reduction of process wastewater discharge, and are more environment friendly to the environment.

Description

technical field [0001] The invention belongs to the technical field of C5 petroleum resin catalytic hydrogenation process, and is a dechlorination method and device suitable for C5 petroleum resin hydrogenation process. At present, the gas-liquid two-phase alkali washing and water washing dechlorination process are generally used in the hydrogenation process of C5 petroleum resin. Background technique [0002] C5 hydrogenated petroleum resin is a colorless or Light colored petroleum resin. C5 hydrogenated petroleum resin improves the chromaticity, adhesion, weather resistance, light and heat stability and compatibility of petroleum resin, which greatly broadens the application field. [0003] At present, the C5 petroleum resin hydrogenation process can be divided into three categories: slurry hydrogenation, spray hydrogenation and fixed bed hydrogenation. Among them, slurry hydrogenation and spray hydrogenation have limitations in their own processes, which limit the poss...
