Chemical and Petrochemical plants convert natural resources such as crude oil, natural gas, ores and minerials into products for a wide range of applications
 
TFC"s products are widely used in the following processes of a chemical plant:                      
 
Catalytic cracking
Catalytic cracking process is a new process in petroleum refining, the purpose is to produce propylene. The reaction temperature is among 510-540℃, pressure 0.07-0.1Mpa.
 
Reaction regeneration
When reaction material mix with 700 deg. C catalyst from the regenerator, it vaporized instantly and react, the reaction oil and gas, injected steam, together with catalyst the raw oil carry gone through the distributing plate, and entering the fluidized bed reactor for further reaction
 
Fractionation
The oil and gas from the reactor enters the bottom of fractionation tower, going through 3 layers of tongue plate, and 8 herringbone baffle, it reaches the separation tower, where gas, light oil, and heavy oil are seperated
 
Gas compression and scrubbing
Cracked gas is compressed and send to the absorbing tower.
 
Gas, liquified gas desulfurization
The stable liquified gas which contains H2S goes from the cracking device to the desulfurization tank, then pumped up to the desulfurization tower to mix with lean amine liquid, which absorb H2S from liquified gas, thus purified.
 
Gas fractionation
The desulfurized refined liquified gas is sent to propane tower, ethylene tower, propylene tower for condensation using circling cooling water as cooler.
