December 8 morning, Lanzhou Petrochemical ethylene plant ethylene plant staff snow on 201J, 501J, 601J compressor station to focus on inspection, related positions also increase inspection frequency of indoor equipment, key parts, key accessories safety accessories verification, Fire equipment equipment, implementation of safety measures carried out a detailed inspection of the workshop in the control room at the entrance to set up a 'big one hundred days' progress display board, the target output, the completion of production, yield completion rate, yesterday's output, future production, etc. The data is displayed in bright red numbers on the display board. The staff can see the progress of the task in and out of the control room, keep the task in mind and gather the indicator in the finger.
Control room, the job carefully monitor the job, carefully look at the DCS screen, technical staff at any time check the position of the key indicators card edge and found problems timely communication and solutions to ensure stable production and reduce production fluctuations. Anti-coagulation measures, inspection personnel do not take the form of post, 'look, smell, touch, listen', large tower pipeline, small pump instrumentation, are one by one check in place to ensure the normal operation of equipment to prevent runaway.
Since the end of 2006 all devices have been put into operation, ethylene plant energy consumption by the early days of 803 kilograms per ton of standard oil dropped to 600 kilograms of standard oil, the device was SASAC Central enterprises in the same type of ethylene energy efficiency benchmark ; Full-density polyethylene plant has become the first set of polyethylene production equipment compliance company. High-pressure polyethylene plant breakthrough 100 days continuous operation record. 10 years, the cumulative development of 25 new products, a number of alternative imported products, the formation of BOPP film, Food packaging membrane, agricultural membrane materials, transparent injection molding materials, injection-resistant plastic, medical materials, cable materials, pipe materials eight series.
In mid-October, the workshop labor unions conducted a comprehensive review of more than 80 proposals on "increasing revenue and reducing expenditure, reducing costs and increasing profits". In the end, based on the actual results, 50 suggestions were submitted for reporting. In the fourth quarter, as the temperature gradually decreased , To bring a lot of adverse impact on chemical production.Ethylene plant production technology from many aspects, carefully protect the production plant 'stable and excellent' to the full-year goal sprint.
First of all, starting from the optimization of production scheduling, and fully enhance the ability of the device's fist products 'Nuggets'. Through the coordination with the PetroChina Northwest Sales Company and the production of petrochemical companies, as far as possible arrangements for seasonal products and high value-added product brand production, as far as possible Strive for maximum benefit.Production Technology Branch and Motor Division work closely with the equipment to actively deal with the hidden dangers, not to run the equipment sick to ensure that spare equipment intact standby, to ensure the device at full capacity and efficient operation, to create conditions for the smooth operation of production.
Under the precondition of safety, environmental protection and high-load operation of each device, it will ensure that each device will not discharge more than the standard, and eliminate the bottleneck restricting the delivery of chemical wastewater so as to maintain the efficient operation of the device. Effect, to meet the equipment under high-load operation under the premise of strict control of circulating water temperature, energy-saving water-saving work done, does not result in energy waste due to enter the winter heating period, the external steam supply unit at full capacity steam supply gap, Production Technology Section scheduling to strengthen the control of the steam consumption of each unit, timely and total coordination with the steam supply unit contact and coordination, to meet the needs of the production unit under the premise of the production at any time dynamically adjust the amount of steam, the steam good, Management and steam cascade utilization.With the production efficiency as the core, strict quality control process of raw materials, three agents, central distillation export, semi-finished products and finished products, improve the fine management level, reduce the unplanned parking of equipment, optimize the production process, Strengthen the process adjustment, to ensure a smooth process, and continuously improve product quality.
Further optimize the process of switching between different grades of products, reduce the production of transitional materials, strictly control the loss of benefit of the output of contracted goods and defective products, and realize the significant reduction of material consumption and energy consumption of the equipment. On the basis of existing optimization and improvement of raw material tank trains Tank trucks and tank trucks to eliminate the equipment defects in cracked raw material unloading systems and further improve the efficiency of unloading trucks and speed up the transfer of purchased cracking materials. In order to optimize the ethylene cracking raw materials, improve light hydrocarbon, lead-drawing oil and liquefied petroleum gas And other high-quality light materials to achieve the goal of achieving double the yield of ethylene plant to achieve the desired goal to create good conditions. Through the tireless efforts of the entire plant staff, the monthly production tasks to be completed successfully, a number of economic and technical indicators to further enhance the Achieve a hundred days of production goals to create a good condition.
