The first successful application of the domestically produced gas raw material cracking technology to produce ethylene

Recently, Engineering Construction Co.
, Ltd.
(SEI) provided process packages and carried out engineering design of two sets of gas feedstock (ethane/propane/butane) cracking ethylene plants which were successfully started up in a company in Ningbo and a company in Heilongjiang
.
This is the first industrial application of China's domestically-made independent technology in the steam cracking of gas raw materials to produce ethylene.
It proves the reliability and advancement of this technology, and marks a new milestone for SEI's independent ethylene process technology and fills another gap in localized technology.

.
???? China's ethylene raw materials are mainly liquid raw materials such as naphtha, and it is developing rapidly in the direction of light gas raw materials
.
In order to comply with the new development trend of the ethylene industry, SEI has developed CBL gas cracking furnace technology adapted to lightweight raw materials, which has greater flexibility in raw materials and operations, and has the characteristics of high steam output, high thermal efficiency, long operating cycle and low emissions
.
The separation process adopts the superior ethylene recovery process independently developed by SEI, which is specially adapted to the separation of ethane and other gas raw materials cracked gas.
It fully considers the rational use of energy, reduces equipment, and reduces investment.
It has the advantages of simple operation and low energy consumption
