Embodiment 1

[0042] see Figure 1-12 A rectification and separation device for light liquid paraffin comprises a base 1 and a processing box 2 . The process box 2 is arranged on the top of the base 1 in an annular manner, and a heater 3 is fixedly connected to the inner wall of the process box 2. The structure and working principle of the heater 3 are known, so they will not be described in detail here. The process box 2 One side wall is communicated with a connecting pipe 4, and the outer wall of one end of the connecting pipe 4 is threadedly connected with a blocking block 5, the outer wall of one end of the connecting pipe 4 is provided with a first external thread, and the inner wall of the blocking block 5 is provided with a first external thread. The first internal thread matched with the external thread, while the block 5 is provided with a seal, the block 5 is connected to the connecting pipe 4 to play a sealing role, and the other side wall of the processing box 2 is connected wit...

Embodiment 2

[0058] A five-stage rectification production process of light liquid paraffin: liquid wax is used as raw material, and the hydrocarbon component is between C9-C15. After the raw material liquid wax is pressurized by the feed pump from the tank area, it first enters 1# rectification Rectification is carried out in the separation device, and the product is extracted. The heavy fraction is pumped to 2# rectification separation device. After rectification and separation, the product is extracted, and the heavy fraction is pumped to 3# rectification separation device. After rectification separation, The product is extracted, and the heavy fraction is pumped to the 4# rectification separation device. After rectification and separation, the product is extracted, and the heavy fraction is pumped to the 5# rectification separation device. After the rectification separation, the product and environmental protection liquid wax are extracted.

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...
