Abstract

The invention relates to a rectification separation device for light liquid paraffin and a five-stage rectification production process. The separation device comprises a base and a treatment box, wherein the treatment box is annularly and movably arranged above the base, the inner side wall of the treatment box is fixedly connected with a heater, one side wall of the treatment box is communicatedwith a connecting pipe, the outer side wall of one end of the connecting pipe is in threaded connection with a blocking block, the other side wall of the treatment box is communicated with an L-shapedpipe, and the vertical section of the L-shaped pipe is slidably connected with a middle box. A circulation hole is formed in the vertical section, located on the inner side of the middle box, of theL-shaped pipe, the middle box communicates with a middle pipe, a switch valve is installed on the middle pipe, the end, away from the middle box, of the middle pipe is in threaded connection with a cylindrical connector, and the cylindrical connector is matched with a connecting pipe; and a bearing plate is fixedly connected to the upper portion of the base. The separation of light liquid paraffinin the liquid paraffin is achieved through five-section rectification.

Description

technical field

[0001] The invention relates to the technical field of rectification and separation of liquid paraffin, in particular to a rectification and separation device for light liquid paraffin and a five-stage rectification production process. Background technique

[0002] Liquid paraffin (referred to as liquid wax) refers to the paraffin containing n-alkanes obtained by using kerosene or diesel fractions as raw materials through molecular sieve adsorption separation or isopropanol-urea dewaxing, or the liquid synthesized in the process of coal / natural gas liquefaction paraffin. Because it is a transparent colorless or light yellow liquid at room temperature, it is called liquid paraffin or liquid paraffin synthesized in the process of coal / natural gas liquefaction. Because it is a transparent, colorless or light yellow liquid at room temperature, it is called liquid paraffin. However, the existing separation and production devices for light liquid paraffin generall...
