Liaoyang Petrochemical overcomes the problem of white oil reuse

Recently, the last cauldron of Liaoyang Petrochemical waste white oil engineering scale-up recovery test was successful
.
The recovered white oil indicators meet the requirements of alkyl aluminum devices and can be recycled
.

This complete set of waste white oil reuse technology has the characteristics of good alkyl aluminum removal effect, high product recovery rate and low comprehensive energy consumption, which plays an important role
in eliminating potential safety hazards, reducing consumption and increasing efficiency, and realizing clean production.

Alkyl aluminum is mainly used in the synthesis of polyolefin catalysts, which are very chemically active, flammable and explosive
.
The Liaoyang Petrochemical Olefin Plant produces dozens of tons of waste white oil containing alkyl aluminum every year, and long-term storage in large quantities has high safety risks
.
Since it cannot be recycled, it can only be sold
at a low price.
In response to this problem, Liaoyang Petrochemical actively carried out research
on the application of waste white oil recovery technology.

Compared with the existing technical routes at home and abroad, scientific researchers adopt a high starting point and original process routes, simplify and optimize the process parameters through repeated data accounting of process flow, operating parameters and equipment types, and make full use of existing equipment conditions to transform
the test device.
They completed the design of the engineering amplification scheme on the basis of small tests, and verified and investigated the whole set of process design and key operating conditions during the amplification test, and finally succeeded
