ECH production process

ECH production process by glycerin method

Product Description

Epichlorohydrin is the main raw material for the production of epoxy resin. It is also an important organic chemical raw material and fine chemical product. It has a wide range of uses. There are three main processes: acryl acetate process, propylene process and glycerin process. In the traditional propylene process, raw materials rely on petroleum resources, and the fluctuation of its basic price is also affected by the oil price.

Features of ECH Production By Glycerin Method

1. The consumption of catalyst is low and composite catalyst is used with high selectivity and yield.

2. Low total investment.

3. Waste water recycling, zero discharge.

4. Normally, it can directly reach the emission standard.

Main Process Comparison

● High temperature chlorination process of propylene

The raw materials are propylene and chlorine, which are low in safety and reliability, dangerous production and short operation cycle; high operation temperature and high energy consumption.

● Propylene acetate process

The raw materials are propylene and chlorine, so there are still problems in safety, low energy consumption, but high equipment investment

● Glycerin process

The raw materials are glycerin and hydrogen chloride, with high safety factor,low energy consumption and less harsh operating temperature.

In order to reduce the use of petroleum resources, the biodiesel industry is developing rapidly. In the process of the development of the industry, the by-product glycerol production has been improved, which provides a reliable source of raw materials for the production of propylene oxide.
