At 9:58 on July 19, the 600,000-ton/year styrene unit of Gulei refining and chemical integration project introduced benzene and ethylbenzene materials for the first time, marking that the unit officially entered the stage of commissioning
.
Benzene and ethylene are the necessary process raw materials for the production of styrene plants.
The alkylation reaction is carried out under liquid phase conditions, and ethylbenzene is obtained after purification.
After dehydrogenation reaction, crude styrene is generated.
High-purity polymer-grade styrene can be obtained to meet the product supply needs of downstream devices and enterprises in the park
.
After the intermediate handover of the styrene plant on April 30, all the staff of the plant worked together to grasp the key points and maintain the key points, overcoming the construction progress caused by the epidemic, the delay in the arrival of equipment and materials, and the inability of the patentee to arrive at the site to carry out technical services.
factors, successively completed the preparatory work for commissioning and commissioning, such as circulating water flushing, steam purging and targeting, device intermodal transportation, oven, catalyst filling, blind plate management, establishment of public works system, and material preparation for starting construction, to ensure the construction and commissioning of styrene plant engineering.
