Covestro's new hydrochloric acid oxidation unit Deacon II officially runs

In the Deacon process, the by-product hydrogen chloride generated in the isocyanate production process is converted into chlorine through a catalytic oxidation reaction, which can be used as a raw material for subsequent production.

Covestro's Shanghai integrated site started the construction of the world's first industrialized Deacon device in November 2008, and it was put into operation in mid-2011.

Deacon II uses the same scale, technology, operation and equipment to bring synergy to operators.

• Obtained 320,000 tons/year of low-cost, low-energy chlorine production.

  
  

• By replacing the purchased chlorine gas, the recycling rate of hydrogen chloride/chlorine gas pipeline network has been increased to 98%, and the corresponding CO2 emissions have been reduced from over 150,000 tons per year to 9,000 tons, which is equivalent to reducing the emissions of 73,000 cars per year.

  
  

• The heat generated in the chemical reaction process will also be recovered and reused in the production cycle in the form of steam, thereby greatly reducing the carbon footprint.
