On July 2, it was learned from Lanzhou Petrochemical's styrene workshop that as of June 30, styrene had completed 55.57% of the annual production tasks, and the material consumption and energy consumption were reduced by 7.2kg/t and 47.268kgEO respectively compared with the same period last year. /t, the total profit hits the best level.
Since the beginning of this year, the styrene workshop of the Lanzhou Petrochemical Rubber Plant has strictly implemented the company’s overall deployment requirements of “seizing market opportunities, producing more profitable products, and maximizing benefits”, adhered to market-oriented, and fully benchmarked the annual production goals and tasks. Coordinated production, strengthened the management of "three fines", strengthened the investigation and rectification of hidden dangers, and vigorously promoted the tackling of difficult problems, achieved safe production and energy-saving consumption reduction with "two hands and two hands", and smoothly realized the "double over half".
On the basis of organizing the high-load production of the equipment, the styrene workshop comprehensively improves the "three-precision" management, optimizes the production process, and strengthens the refinement of process control. The workshop focuses on in-depth benchmarking in areas such as efficiency creation, technical and economic indicators, and fine management. Weekly calculation and monthly analysis are performed to improve the control level of various technical and economic indicators. Leading cadres strengthen on duty, especially on holidays and weekends, take the initiative to watch, coordinate and deal with various abnormalities in production at the first time; professional and technical personnel monitor the various operations of the team through various forms such as on-duty, on-duty, telephone, and work groups. Provide timely guidance and control on process fluctuations and other situations; the team strengthened inspections, precise operations, and required "snap-side" operations on process parameters such as pressure and temperature, so that the optimal operation of the equipment was always under control, and the product quality was effectively improved. From January to June, the high-quality product rate of device products reached 100%.
In response to the fact that the equipment is aging and the safety risk is high, the styrene workshop has strengthened the investigation and remediation of hidden dangers. The workshop party branch carried out the “five first” activities for party members in a timely manner, gave full play to the exemplary role of party members, and distributed the indicators for the investigation and rectification of hidden dangers to each party member, so that the indicators should be carried by the party members first, thereby motivating the masses of employees to jointly develop device compliance, Safety hazard investigation, the problems identified in the investigation, the responsibilities and measures are specified in a list to ensure that the rectification is implemented one by one. Especially the major hidden dangers of the E-35 cylinder leakage of the ethylbenzene tower reboiler discovered by the party members were reported to the workshop as soon as possible. The workshop organized professionals to analyze the cause of the leakage and formulate treatment measures, which successfully eliminated the hidden dangers and ensured the normal operation of the installation. produce. From January to June, a total of 52 hidden dangers were identified, and rectification measures were formulated one by one, which effectively ensured the safe and stable operation of the device.
Styrene workshop takes the breakthrough of equipment production problems as the starting point, and actively organizes professional and technical personnel and basic-level technicians and party members to carry out activities such as solving problems and suggestions and suggestions based on the actual situation of the equipment. In view of the large consumption of high-pressure steam and high energy loss in the styrene plant, the workshop professional and technical personnel led the staff to check the process flow, make timely adjustments, check for leaks in key equipment and key points, and replace the traps, etc. The amount of steam saved is about 60 tons per day. At the same time, in order to reduce the consumption of -12°C salt water, the workshop organized a problem solving team. After continuous exploration and research, the vacuum pump sealing liquid was finally changed from hot ethylbenzene to cold ethylbenzene in the tank area, which lowered the temperature of the sealing liquid and saved frozen salt water every hour. More than 3 tons, effectively reducing the energy and material consumption of the device, and significantly increasing the efficiency. From January to June, the device achieved an efficiency increase of more than 1.6 million yuan.
