Placeholder for Huanqiu steam cracking technology.
Description to be developed here.

Preliminary information details as related to Guangdong Petrochemical where the technology is deployed:

31^st Mar 2022: The ethylene plant adopts Huanqiu's own ethylene process technology and is scheduled to be delivered on June 30, 2022. According to the feedstock situation, the cracking furnace adopts a high steam production process. After the cracking gas is cooled by the traditional primary emergency cooler, it is also further cooled by the boiler feed water to cool down the cracking gas again. In order to improve the coke removal cycle of the cracker, the radiating section stove pipe adopts an enhanced form of heat transfer to reduce the tendency of coking on the inner surface of the stove pipe, increasing the coke removal cycle by more than 30%.

4^th Jul 2022: The 1,200,000 ton/year ethylene plant is the "leading" plant in the chemical industry zone, mainly producing ethylene, propylene and other products, as well as by-products such as hydrogen, methane-rich gas, cracked C₄, cracked gasoline and fuel oil. The unit is contracted by EPC of China Huanqiu Engineering Co., Ltd., jointly executed by Huanqiu Beijing Company and Huanqiu Sixth Construction Company, and adopts the complete set of patented ethylene technology independently developed by Huanqiu Company. Huanqiu Company has designed and built a single liquid cracking furnace with the largest production capacity in China at present, and applied the domestic cracking gas compressor with the largest power, thus opening up the whole process of "six transformations" in the field of refining and chemical engineering for the first time.
