CBL Furnace Technology

SINOPEC started the development of CBL Cracking Furnace technology in 1984 and the first commercial plant was set up at Liaoyang Petrochemical Co. of PetroChina in 1988. To date, CBL I-VII cracking fu...

Swirling Element of Radiant Tube (SERT)

Cracking furnace is an important facility for production of basic petrochemical blocks such as ethylene and propylene. Feedstock through the tube in the furnace is heated and converted into desired pr...

Ethylene Recovery Technology (LECT)

Ethylene recovery technology is used for olefin recovering from cracked gas and to produce polymer-grade ethylene, propylene and side products including hydrogen, mixed C4s, gasoline, PGO and PFO.

Tail-end Selective HT for Removal of Acetylene in C2 Fraction

The tail-end selective hydrogenation process is applicable to tail-end process ethylene unit for removal of acetylene in C2 fraction. The catalyst used in the process is very important to ethylene cra...

Refinery Off-gas Recovery by Shallow Cold Oil Absorption Technology (COAT)

Refinery off-gas is rich in ethylene and ethane, meanwhile it also contains some other alkene and alkane such as propylene, propane, and butylene. Earlier, refinery off-gas is mainly burned as fuel ga...

Catalytic Cracking of C4 Olefin to Propylene and Ethylene Technology (OCC)

Naphtha steam cracking process, oil refining process and methanol to olefins process produce large quantity of low value by-product streams containing C4/C5 olefins. Increasing the value of those C4/C...

Pyrolysis Gasoline Hydrogenation Technology (PGH)

Pyrolysis gasoline hydrogenation (PGH) technology is used for hydrotreating pyrolysis gasoline (PG) from naphtha and gas oil steam cracker. PG is a main by-product of ethylene steam cracking system. S...
