Some issues regarding the propylene gas compressor in PP plants
Thread Content
Solution: 1. Why is a labyrinth compressor used for the cyclopropane gas compressor in the PP plant? 2. What are good methods to reduce the oil carryover issue in compressors?
As required by the design, oil is used to reduce the amount of oil that needs to be injected, or oil-free lubrication is employed
1. The labyrinth compressor is also a type of oil-free compressor; its sealing principle relies on throttling sealing, and it lacks vulnerable components such as piston rings, support rings, and packing rings, resulting in high operational reliability. At the same time, due to the absence of piston rings and the friction from support rings, it achieves good energy-saving effects. 2. What type of compressor is it? If it is an oil-based screw compressor, the amount of oil carried can be reduced by replacing the oil separator filter element; centrifugal compressors generally do not carry oil. For reciprocating compressors with cylinder oil lubrication, the amount of oil carried can only be reduced by decreasing the dosage of oil, or by converting them to a oil-free lubrication system.
Maze compressors are used because the PP recycled gas carries powder, which helps to prevent cylinder wear
There are already many options when choosing a labyrinth compressor. Is the upstream section of the compressor an propylene gas oil washing system? When you mention oil in relation to the compressor, do you mean the oil brought in from the upstream section, or the lubricating oil built into the compressor itself?
