Documentary of Yinguang Group's Innovation Strategy Empowering High-quality Development

"Process optimization is to systematically transform the company's existing production processes and processes through advanced technology and equipment, which can not only reduce production costs, but also double the driving effect of the entire industrial chain
.

" This is Gansu Yinguang Chemical Gong Xiaolong, deputy director of the TDI plant of Industrial Group Co.

In 2021, Yinguang Group will continue to implement the innovation-driven development strategy, focusing on releasing production line capacity, improving product yield, reducing material consumption, and "four new" technologies, etc.
, taking problem-oriented and "horse racing" as a platform to implement process optimization projects 42, with a cumulative saving of more than 42 million yuan, and continue to promote the continuous, automated, intelligent and unmanned development of production lines
.

Reduce costs and increase efficiency to activate the innovation engine of the industrial chain

　Reduce cost and increase efficiency to activate the innovation engine　of the industrial chain

In the past two years, affected by the new crown pneumonia epidemic, the price of chemical raw materials has remained high, and the new domestic TDI production capacity has been released sharply, which has brought a great test to the development of Yinguang Group's TDI industry chain
.

To this end, internal process optimization, potential cost reduction, innovation and improvement have become the "magic weapon" for enterprises to compete in the market and achieve high-quality development

During the overhaul in 2021, Yinguang Group implemented a series of process optimizations, such as increasing the head of the circulating pump, optimizing the structure of the heat exchanger, and expanding the main line of the refrigerated toluene by implementing the optimization project of the refrigerated toluene system of the TDI production line, reducing the temperature of the refrigerated toluene and completely eliminating the The hidden dangers and technical bottlenecks of high phosgene content in the exhaust gas and affecting the load of the production line are eliminated
.

After the implementation of the project, the feed volume of the carbon monoxide recovery unit has increased by 67%, and the TDA feed volume has reached 6,800 kg per hour, which is the best record in history

At the same time, with the steady increase of TDI production capacity, a series of process optimization projects have also been carried out for the supporting chlor-alkali production line
.

Through the implementation of the second-generation zero-pole distance transformation project of the electrolytic cell, the employees of this production line increased the current density by 0.

"To achieve high-quality development, we must achieve connotative growth driven by innovation
.

In recent years, Yinguang Group has been benchmarking world-class enterprises, continuously increasing independent innovation and breaking through key core technologies, and the contribution rate of new civilian products for the year is 36%

　　Energy saving and emission reduction promote the green transformation of production lines

　Energy Conservation and Emission Reduction Promote Green Transformation of Production Lines　Energy Saving and Emission Reduction Promote Green Transformation of Production Lines

　　Yinguang Group injects the concept of green development and clean production into every link from raw materials to finished products, continuously carries out process optimization, and strictly controls the transmission and accumulation of pollutants downstream
.

　　Aiming at the problems of high acid content of acid nitrates and large amount of solid waste generated in alkaline wastewater in the production line of nitrous oxide
.

Yinguang Group has successively implemented projects such as nitrification separation system optimization and washing process optimization and transformation, redesigned and installed equipment, adjusted the technological process, effectively reduced the acid content of nitrification, and helped the green and clean development of the production line

　　"In 2021, each unit will sign 15 tasks for technological innovation, and successively implement projects such as zero discharge of process water and technological transformation of workshops, which not only reduces the amount of wastewater discharge, but also meets the needs of flexible production of current production lines and personalized deep processing of products.
It also has obvious effects on reducing the labor intensity of employees and improving the working environment
.

" said the person in charge of the technical quality department of Yinguang Group Hanneng Company

　　Yinguang Group also regards improving the yield of DNB as an innovative research direction, and constantly adjusts the reaction parameters and temperature, minimizes the generation of side reactions, and recycles alkaline waste drugs
.

After repeated verification and solidification optimization, the yield was successfully increased by 1%, and the benefit was more than 2.
