Sinopec News Network reported that Zhongke Refinery has thoroughly implemented the spirit of reducing coal and carbon, combining internal cost reduction and efficiency enhancement with green environmental protection
.
Since June 8th, CFB boilers will burn chemical sludge at full load, which is expected to reduce 6,000 tons of thermal coal, reduce costs and increase efficiency significantly, and economic and technical indicators such as power supply standard coal consumption and heating standard coal consumption have been optimized
The chemical sludge oil is the sludge oil recovered during the oil transportation, replacement, and discharge during the cracking plant.
The original treatment method was to entrust a qualified manufacturer to handle it.
This not only wastes the heat value of the sludge oil, but also pays a processing fee
.
Zhongke Refining and Chemical Co.
In order to maximize the use of the original process and reduce the construction cost, the CFB boiler was modified to mix with slop oil.
Zhongke Refining and Chemical took the initiative to carefully study the process and characteristics of the device.
By adding a return heat exchanger, the slop oil temperature was effectively reduced
.
In view of the characteristics of chemical pollution oil that is easy to block the filter screen and other characteristics, management personnel and operators take special care on site to regularly measure oil temperature and oil pressure to ensure safe and reliable operation of transmission pipelines and ensure that no drop of dirty oil appears on site
.
Process, equipment, and safety professions work closely together to increase the amount of mixed firing, and closely monitor and record on-site operating conditions in detail
.
After many days of exploration, the amount of blended firing was gradually increased to the maximum amount, and a set of effective operation methods were explored to ensure that the economic and technical indicators and the green environmental protection indicators were met
