Service Introduction

Main research direction: Clean and intelligent chemical process
 

Current main areas: continuous automatic control production process development of fine chemicals
 

Using the process enhancement technology researched and developed by our team, develop the continuous automatic control production process of fine chemicals, realize the transition of fine chemical products from intermittent, open and manual processes to continuous, closed and automatic control, improve the utilization of raw materials and energy, and reduce pollution from the source Discharge, reduce safety risks, and essentially achieve green, clean and safe production of fine chemicals.
 

China is a big country in the production of fine chemical products, but it is by no means a strong country. The production processes of the majority of fine chemical companies still use batch, manual and open equipment for production. The process technology is neither chemical nor fine. Relying on the technical advantages of Tianjin University's chemical discipline, our team independently developed high-efficiency reactors such as high-shear, micro-structure, micro-tubes, and high-efficiency separation and purification systems, which have been widely used in the upgrading and transformation of fine chemical production technology, and the original batch , Manual and open production processes are upgraded to continuous, automatic and closed production processes. The continuous process avoids the batch nature of the product and the quality is stable; the automatic control process solves the labor problem, avoids the quality and safety risks caused by human factors, and improves the safety level; the closed operation refers to the production process materials in the closed equipment and pipelines Continuous flow, reaction and purification in separation equipment such as reactor and rectification extraction, avoids respiratory gas pollution during discharging during intermittent operation, reduces gas-phase environmental pollution and reduces the risk of flash explosion of flammable and explosive gases.
 

Our team’s process enhancement technology has been successfully used in the continuous clean production process of fine chemicals. The reaction process involves phosgene chlorination, sulfonation, oxidation, nitrification, chlorination, cyanidation, rearrangement, diazotization, and neutralization. , The separation process includes rectification, extraction, absorption, desorption, crystallization, phase separation and filtration, etc., and good results have been achieved.
