Are there many manufacturers for membrane separation on small units?
Thread Content
Our factory hasn’t started yet; we are in the process of evaluation. Could you give some suggestions? Thank you!
We have 30,000 tons per year in operation; let’s analyze whether it’s feasible
It facilitates the recycling of propylene resources and improves the efficiency of the plant.
Under normal use conditions, how many years is the typical lifespan of a membrane?
Under normal operating conditions (without liquid present, no oil leakage from the compressor, and no significant fluctuations in pressure), the membrane has a shelf life of 2 years; under typical circumstances, it can be used for 4 to 5 years.

All newly built small units are equipped with membrane recovery systems, and those that are already in operation are also being considered for modification to add such systems. Last edited by leefun on 2009-4-13 11:23.]
Thank you:handshake
The device for producing polypropylene powder in a compact format has a significant effect on reducing the consumption of propylene; generally, the membrane modules need to be replaced every 3 years. Our company’s propylene consumption is around 1.06
Unit consumption of 1.06? Is it still this high after membrane separation?
By rough estimation, over 90% of the small units have been modified with membrane separation and recovery systems. Apart from those that have stopped production and a few that were demolished, most are still in operation. The recovery rate of propylene monomer can exceed 90%. As for how much the material consumption can be reduced, no statistics are available; generally, it is determined by the manufacturers themselves. The service life of the membrane can be guaranteed to be two years; however, the actual duration of use varies depending on the conditions of the gas source. The total investment for this project is not large; the payback period is about half a year.
