As of early October, since the Fushun Petrochemical overhaul, the thermal efficiency of the distillation furnace has increased by 2.6 percentage points, and the thermal efficiency of the hydrogenation furnace of the diesel hydrogenation unit has increased by 2.9 percentage points. The thermal efficiency of the heating furnace heating furnace has increased by 1.2 percentage points. Is Fushun Petrochemical Plant II part of the monomer equipment in September calibration data.
Fushun Petrochemical use of large maintenance equipment, technology, three agents and other advantages, the implementation of a new round of production optimization, mining device potential, product yield, pollutant emissions and other production and environmental indicators were made before the progress of progress, production quality And the ability to achieve a substantial increase in efficiency.
It is understood that the oil plant using a large overhaul, the 15 sets of equipment, 34 beds, 48 formulations were replaced, through the optimization of raw materials and product structure, the yield of products has been greatly improved, based on estimates, the annual efficiency $ 936 million.
In order to further reduce diesel production and increase naphtha production, this plant to improve the diesel fuel and hydrogenation plant structure, diesel fueling unit blending straight-run diesel ratio from 86% before the maintenance to 50% Naphtha yield increased by 7 percentage points in the current production of coal conditions under consideration, the plant can increase naphtha 150,000 tons per year to reduce the production of 50,000 tons of diesel, efficiency of 150 million yuan.It is estimated that this The proportion of straight-run diesel oil blended in the diesel fuel plant under the condition of non-production of coal transportation can be further reduced to 40%, and the proportion of straight-run diesel oil in the hydrocracking unit can be increased by 400,000 tons of naphtha.
Oil Plant with a major overhaul, the implementation of 11 major energy-saving technological transformation projects, to create a new bright spot, heating furnace thermal efficiency, heat supply temperature and other indicators on a new level, each year can save 16,600 tons of standard oil.
After the transformation, the temperature of the hot blast furnace was reduced from 230 degrees Celsius to 278 degrees Celsius, and the thermal efficiency was increased by 2.6 percentage points, and the energy saving rate was 3526 tons per year. On the 12 unmodified heating furnace air preheater was sweep ash and replace the heat pipe, through the depth of optimization operations, strict implementation of the 'one furnace a card' management, to strengthen the assessment, heating furnace thermal efficiency increased by 0.3 to 0.5 percentage points.
During the overhaul period, the oil plant will carry out inspection or inspection and repair of 14 external meters and 19 sets of meters for each other. The new meter and the reasonable parameters are measured and the measurement data are measured accurately. For the supply of materials 4755 tons.
To heavy oil catalytic flue gas denitrification system as the representative of environmental protection standards upgrade has become Fushun Petrochemical Plant production quality improvement is an important part of the maintenance period completed the heating furnace 89 low nitrogen fire mouth burner replacement, continuous monitoring after the transformation The data show that all the nitrogen oxide emission targets are substantially reduced and the distillation unit is reduced from 211 mg per standard cubic meter to 86 mg.
