On June 5, Beijing Sperox Technology Development Co.
, Ltd.
announced that its self-developed new environmentally friendly coking inhibitor product was successfully applied in the ethylene cracking unit of Dushanzi Petrochemical with an annual output of 1 million tons
.
After 3 months of operation and use, the results show that the steam-hydrocarbon ratio of the cracking furnace of the ethylene cracker is stable, the absolute pressure ratio of the Venturi increases slowly, and the surface temperature of the furnace tube TMT is stable
.
Dushanzi Petrochemical's ethylene cracking unit with an annual output of 1 million tons adopts the technology of Germany's LINDE company.
It was successfully started in September 2009.
According to the requirements of the patentee, DMDS products have been added.
However, with the heavy and diverse petrochemical industry raw materials The ethylene cracking furnace tends to develop in large scale with high temperature and short residence time
.
Cracking furnace is one of the core equipment of ethylene plant
.
In the gas-phase cracking process of light hydrocarbons, while producing ethylene, propylene, butadiene and other products, it is also accompanied by the process of secondary reaction and coking and finally generating carbon
.
The new environmentally friendly coking inhibitor developed by Sperler is an alkaline substance that does not contain phosphorus compounds.
The product contains active components that passivate the metal surface of the furnace tube.
It has the characteristics of no corrosion and high boiling point.
After the product is decomposed, it forms The substance can not only passivate the metal surface of the furnace tube, but also reduce the catalytic coking activity of the metal, and also terminate the free radical reaction of non-catalytic coking, so as to achieve the purpose of inhibiting coking
.
According to the technical staff of Dushanzi Petrochemical's ethylene plant, extending the operation period of the cracking furnace of the ethylene plant can reduce the steam, industrial wind and natural gas required for the charring of the cracking furnace
.
