This year, Jinling Petrochemical Chemical ran a coal chemical plant to overcome the unfavorable factors of rising coal prices. Since then, it has intensified its management and innovation and tapped the potential to realize the transformation from a large loss-making unit to a profit-making unit.
From January to October, a total of 77,400 tons of hydrogen was supplied, an increase of 25% from a loss of 50 million yuan in the same period of last year to a profit of 50 million yuan this year. Both the amount of hydrogen supply and profits have created the highest level in history.
Since the pressure, the formation of a new management situation
'Implementation of the device throughout the year the number of unplanned downtime is zero, large units downtime is zero, the annual supply of 85,000 tons of hydrogen.' Earlier this year, a chemical workers in the General Assembly, the Director Wang Deli together with the workers under pressure.
This year, the operation department is in response to last year's losses, large unit problems and more criticisms. In the face of the pressure of overhydrogenation in the refinery plant in 2017, the operation department leads the full confidence of the whole staff and turns pressure into impetus and cohesion , Pull up their sleeves refueling dry, jumped up 'pick peaches.' They organize staff and workers to seriously carry out the 'full discussion Huiyi big', change their concept, check the problem, make recommendations, set strategies, see the action, the pressure on his shoulders, Hold the charge in your hand and put the hard work in the line.
Party members and cadres to take the lead, with a level, and gradually form a 'self-strict demands, strict working standards, the implementation of strict examination' of the new pattern.
From January to October, the Ministry of Operations received a total of 200 technical suggestions made by employees, including the building of the "Three Foundations", reducing cost and increasing efficiency, and analyzed and appraised, compared and implemented the policies one after the other, which motivated the enthusiasm of employees to offer advice and suggestions for the improvement of management , But also played an active role in upgrading grassroots management.
Build a solid 'three base' to avoid unplanned lockout
At 8:20 on November 27, Wu Lin, a member of the Purification and Synthesis Zone, started his daily morning inspection. After walking around the equipment, he specially came to the work area for ditch inspection to see that there was no debris in the ditch and was clean and clean. Other patrol points go.
This is one of the things Wulin must check every day.
This year, the operation department took the opportunity of the company 'Equipment Management Year' as an opportunity to start from a trivial matter, quantify the criteria, refine the examination, and build a solid foundation of 'three bases' to effectively prevent unplanned suspension of work.
They control the site management standards of "one level, two net levels, three levels, four levels and five levels", and the management personnel take the lead in strict implementation and do a solid job of key equipment check, no leak check and overhaul quality check on site management. 24 hours a day service production, and the management responsibility of each device implemented to people, assessment of people.This year, the coal mill picking bar originally scheduled for 6 days of repair, 3 days in advance to complete the tube machine gearbox troubleshooting , Staff fighting for 20 hours in a row, with the least time to put the equipment used.
At the same time, the operation department will once a month in the post-inspection into once every two months, departments and work areas strictly adhere to the day morning inspection, Zhou Gang inspection system, strengthen the post inspection implementation of the problem 'look back' to form a closed-loop management, to eliminate equipment defects , Truly 'no small event on the scene, the problem is not overnight' to prevent equipment failure, to ensure a smooth hydrogen supply.
From January to October, the coal-water slurry plant operated continuously and safely for 295 days with a total number of unplanned downtime of zero. Hydrogen production increased by 15,400 tons and efficiency increased by nearly 50 million yuan, the highest level in history.
Technological innovation to tap the potential benefits
Since the beginning of this year, the price of chemical coal has continued to rise, the average price has risen by nearly 50% per tonne over last year, and the cost of production has been on the rise. This has brought unprecedented pressure on the operation of facilities. The operation department vigorously implemented technological innovation, optimized production, Efficiency.
They pointed out the advanced indicators of the group companies, conscientiously searched for gaps and shortcomings, and held technical exchanges with Maoming Petrochemical Co., Ltd. on their hydrogen production and management. They explored issues such as burners and refractory bricks that restrict the long-term operation of the gasifier and explored the best Technical improvements.He changed the gasifier cone to the new furnace brick, the operating cycle increased from 4200 hours to 5000 hours, gasifier burner and single-furnace operation hit a new record of 126 days, reducing the frequency of the furnace, saving The cost of overhaul. The gasifier burner flange try to use top cone nut tightening torque wrench installed in place to avoid beating with a hammer to solve the risk of flange leakage, careful care, the healthy operation of equipment The more secure the more bar.
At the same time, after the operation department communicated with the relevant department, it took the initiative to mix more than 5,000 tons of low-grade "Shenyou 2" ultra-low ash coal and used "coarse grains" and "fine grains" together to draw lessons from the use of the coal When the blockage slag parking lesson occurred.Through the optimization pulping mill pulping rod parameters, adjust the amount of coal slurry additives to break the low ash coal pulping operation limits, so that the coal to meet the requirements of high-load production.At the same time, Strengthen the sampling analysis, accurate grasp of coal quality data, reasonable adjustment of blending plan, reduce the high-load operation risk.
After the implementation of these measures, the coal slurry concentration, viscosity, particle size and other 100% qualified when mixing and burning, stable operation of the device, while maintaining a good hydrogen quality, reduce costs and improve efficiency while feeding 20%.
