Since the beginning of this year, Shanghai Petrochemical has optimized its product structure and pushed its refining units to increase the production of propylene
As an integrated refining and chemical production enterprise, Shanghai Petrochemical has two production routes for propylene products.
As an integrated refining and chemical production enterprise, Shanghai Petrochemical has two production routes for propylene products.
Enhancing the digestibility of the unit is the key to breaking through the bottleneck of propylene production
In the first half of 2021, Shanghai Petrochemical will carry out the largest-scale overhaul and renovation in the company's history
On the basis of the modification of the device, the optimization of the raw material structure can further tap the potential of the device
.
The refining department uses the coking liquefied gas produced by the two delayed coking units as the raw material for cracking, and sends it to the catalytic cracking unit for refining
.
In order to solve the problem of high sulfur content in coking liquefied gas, Shanghai Petrochemical Zhou Guoming Labor Model Innovation Studio carried out concentrated research, and accurately added carbonyl sulfide removal aids in the coking liquefied gas desulfurization unit to effectively reduce the sulfur in liquefied gas.
content and improve the quality of propylene
.
At the same time, the blending amount of coking liquefied gas entering the gas separation unit will be gradually increased in stages, and the blending ratio will be precisely controlled to ensure the output of propylene
.
In August last year, the desulfurized coking liquefied gas was sent to the gas separation unit for the first time for blending
.
At present, the daily blending volume reaches 190 tons, and 27 tons of propylene can be recovered
.
