In recent years, the cost of refining and processing has been continuously rising, and on the premise of ensuring safe and stable production, the Group has fully tapped the potentials of three production facilities such as atmospheric pressure, catalysis and coking, and actively explored and applied various energy-saving technology measures. After the reform of the atmospheric pressure and coking wastewater recovery system, coking cold coke water and decoking water system in the workshop, the coking unit realized that the sewage outflow was zero. In the earlier period, the atmospheric sewage was reformed, and the wastewater was introduced into catalysis and coking with ammonia water. Each month, it can not only save more than 4,000 tons of fresh water, but also reduce the discharge of more than 3,000 tons of pollutants, with annual efficiency of nearly 100,000 yuan.
On this basis, the alliance will further focus energy management on production details. Completion of the reduction of the cooling water pipeline in the same period, as well as the addition of fresh water metering instrumentation into the device, water reforming of the coke filling station at the surface, etc., are all low-cost, no-cost projects. In the latter case, after reforming the water used for rushing to the ground, the workshop has analyzed and compared several schemes and adopted the method of draining wastewater from the decoking water reuse system pipeline. Only one valve and one hose can be added. Save nearly 3 tons of water every day.
In the near future, a total of 11 similar minor renovations and minor innovations have been carried out. The cumulative cost is less than RMB 6,000. Although the amount of water and electricity conservation is limited, these sporadic details add up and can save more than 42,000 tons of water every quarter. Saving 50,000 degrees or so.
The Changling refinery has changed its effectiveness
A few days ago, Changling Branch Co., Ltd. jointly used a coking cooling water pipe for coke-pumping to reduce the diameter. After the implementation of this small cost of 76 yuan, the cooling water consumption of the coke pump was reduced from 0.5 tons per hour to 0.3. Within tons.
