Issue 9, 2014 - Breakthrough in the pilot test of succinic acid by biological method

A breakthrough was made in the pilot test of succinic acid by biological method

Recently, Sinopec's major scientific research project, the first domestic biological succinic acid test plant, and the 1000 tons/year succinic acid pilot plant of Yangzi Petrochemical successfully completed the third production test task, and produced high-purity succinic acid products, laying a good foundation
for the research and development of the subsequent 10,000-ton process package of the pilot plant.

Succinic acid is an important organic chemical raw material and intermediate, mainly used in medicine, food industry, etc
.
It is also a degradable additive, added to plastics, rubber, with efficient degradation function, help eliminate white pollution
.

The traditional production of succinic acid is mainly prepared from butane as raw material, which has a great
impact on the environment.
Yangzi Petrochemical and Nanjing University of Technology jointly developed biological fermentation method synthesis of succinic acid technology, pilot plant using corn as raw material in the test stage, every 1 ton of succinic acid product produced, can absorb 0.
37 tons of carbon dioxide, the production process and products have typical environmental protection characteristics; industrial equipment to increase front-end processing unit, can use straw as raw material, for farmers to process straw found a new way, providing both beneficial to enterprises and environmental protection of the comprehensive solution
.
Therefore, using this technology, carbon dioxide and straw become recyclable resources, and the industry is a typical green and low-carbon industry
.

Yangzi Petrochemical 1000 tons/year succinic acid plant includes strain breeding, anaerobic fermentation, separation and purification and other treatment units, the test device has formed a series of its own technology, in terms of material consumption, energy consumption and other aspects of the leading in China, the world's advanced level
.

The device is an important topic for the development of biomass resources to replace fossil resources under the strategy of promoting green and low-carbon technology, and the completion and operation of the project will provide an important basis
for the transformation of new biorefinery processes into sustainable industrial models.
At present, the fourth phase of the succinic acid pilot plant has been successfully started, and the whole process of test production of the device is steadily advancing
