Recently, Covestro announced that its integrated hydrochloric acid oxidation (Deacon II) project in Shanghai has officially started.
The project will further reduce production energy consumption and costs, improve production efficiency, and contribute to Covestro's goal of promoting sustainable development and realizing a circular economy.

It is understood that the Deacon process enables the by-product hydrogen chloride generated in the isocyanate production process to be efficiently converted into chlorine, which can be used as a raw material for subsequent production.
This high-efficiency hydrogen chloride to chlorine process is based on the catalytic oxidation of hydrogen chloride, which can reduce energy consumption by more than half compared with the traditional process.

Korth Chong Integrated Site Shanghai in 2008 Nian 11 Yue launch the world's first industrialized construction Deacon device, and in 2011 put into operation in mid.
Under the concept of " intelligent copy " , the construction of the Deacon II device started at the end of 2018 .
Deacon II uses the same scale, technology, operation and equipment to bring synergy to operators.

Korth Chong, senior vice president, general manager, Integrated Site Shanghai Chen Yun explained, Deacon II maximum capacity and efficiency of the device than Deacon I will increase about 20% .
In addition, the heat generated in the chemical reaction process will also be recycled in the form of steam and reused in the production cycle, thereby greatly reducing the carbon footprint.
The operation of Deacon II will add an additional 160,000 tons of low-cost, low-energy chlorine gas production to Covestro's Shanghai integrated base each year .
By outsourcing to replace chlorine, Deacon project will create within Korth Integrated Site Shanghai hydrogen chloride / increase the recycling rate of chlorine gas pipeline network to 98% , corresponding to an annual carbon dioxide emissions from more than 15 drops tons to 9 tons, This is equivalent to reducing the emissions of 73,000 cars per year .

Covestro's Shanghai Integrated Base will celebrate its 20th anniversary this year .
As of the end of 2020 , the total investment in the Shanghai integrated base has exceeded 3.
5 billion euros, making it the company's largest production base in the world.
Because of insisting on applying innovative technology in the manufacturing process to achieve sustainable development, the Covestro Shanghai Integrated Base was selected as the first green factory in the Shanghai Chemical Industry Zone in 2018 and was selected as a national-level green factory list issued by the Ministry of Industry and Information Technology of the People’s Republic of China.
