As of December 25, Guangzhou Petrochemical ethylene production totaled 222,400 tons, more than 222,000 tons of annual production targets, complete the annual plan 6 days in advance.
A total of 7 sets of cracking furnace in Guangzhou Petrochemical Chemical Company, a 6-by-1 preparation under normal production conditions.According to the plan and requirements, all cracking furnace must be completed before July 1 low-nitrogen burner reform; cracking G furnace due to the service life of , Need to replace the furnace tube and lining, the construction period of more than 60 days.
The construction of a low-nitrogen burner combined with the cracking of the cracker means that there is basically no standby furnace for 2017. It is crucial to ensure the smooth operation of the six cracking furnaces under high load.
The Ministry of Chemical Industry will optimize the scorching furnace pyrolyzing work according to the reconstruction plan and continue to optimize the construction network to shorten the construction time of the pyrolyzer low-nitrogen burner reformation. They strictly implement the fire prevention measures at the hot spots and the hard isolation measures at high altitudes Arrange special arrangements with the construction unit for each construction site to conduct a comprehensive planning to dynamically adjust the construction progress. A number of auxiliary processes to make time or space adjustments to avoid cross-operation to ensure safe and orderly transformation of the work.
Affected by the overhaul of Series II refinery, from May to August, the cracked feedstock deteriorated, the naphtha alkane value decreased by about 1.36% and the light naphtha alkane value decreased by about 1.89%, bringing about the completion of annual production tasks Adverse effect.Announced a number of chemical industry to take the initiative to respond to changes in cracked raw materials, and continue to optimize the cracker, cracker compressor to enhance the load, increase the amount of feed; strict compliance with discipline and operating discipline, dynamic optimization and adjustment device loading load, cracking Depth control, the amount of hydrogen in the hydrogenation reactor, the reflux ratio of the rectification tower and other key parameters, the impact of the deterioration of the raw material on the output of the plant is reduced to a minimum.
Since the overhaul of the vehicle on January 13, 2016, the cracker has been under high-load production and some problems have been encountered which affect the long-period high-load operation of the unit. The chemical industry has been tackled through continuous research and optimization, for example, Agent to solve the problem of high suction pressure in the four sections of cracked gas compressor. By modifying the existing process, the washing oil is changed to hydrogenated gasoline to improve the wash oil quality and ensure the long period operation of the unit. By periodically off-heating the ethane cycle EY1463 injection of methanol, increase D1690, D1680, D1670 to D1660 across the line and other measures to solve the problem of propylene machine system with water blocking.
