Title:
PRODUCTION PROCESS FOR CHLORINATED PARAFFIN
Document Type and Number:
WIPO Patent Application WO/2019/114739
Kind Code:
A1
Abstract:
A production process for chlorinated paraffin, comprising a reaction kettle, and an absorption kettle (6). The reaction kettle comprises five sequentially communicated reaction kettles from a first reaction kettle (1) to a fifth reaction kettle (5). Paraffin oil is communicated sequentially in the reaction kettle set and subjected to a photocatalytic reaction with chlorine; reaction tail gas of each reaction kettle is introduced into the subsequent reaction kettle; reaction tail gas of the fifth reaction kettle (5) is introduced into the absorption kettle (6) to be mixed with pure paraffin oil; chlorine in the tail gas is absorbed by high-purity paraffin oil, and the paraffin oil followed by the absorption is used as a raw material of the first reaction kettle (1); and the tail gas of the absorption kettle (6) is discharged into a tail gas header and further sent into a tail gas treatment system.
