【Polyether polyols】Issues in vacuum pump selection

2015-09-23View Original

Thread Content

This post was last edited by Xiao Gong 1985 on 2016-4-3 09:55. Hello everyone, I am producing polyether polyols in a reactor of type 803, with a working vacuum of 60 mbar. How long does the reaction take? How much pumping capacity is required for the vacuum pump? About 8 hours. Thank you!

A 80-cubic reactor. How long will it take?

Polyether polyols: with a domestic production capacity of 250,000 tons, we have produced several batches of them! Please contact 0533-4139139

So, manufacturers that only know how to obtain blueprints to produce vacuum equipment can’t be considered real manufacturers; they are merely processing plants……

There are also an enormous number of manufacturers that produce various types of pumps in Zibo

The rate of water evaporation cannot be calculated using formulas, not only under normal temperature and pressure but also under certain levels of vacuum. There is no unified answer to this issue in the scientific community; as a result, it is impossible to determine the actual amount of water that has evaporated, let alone obtain an accurate figure for the content of polyether polyols. This is currently a field involving advanced technology on the international stage, and it’s not something that can be achieved simply by evacuating a tank········
