Yan’an Energy Chemical Gasification and Purification Center of Yanchang Petroleum: Coal slurry recovery boosts efficiency Author/Source: Yan’an Energy Chemical, Yanchang Petroleum Date: 2022-03-03 Clicks: 11 Recently, the gasification and purification center managed to recover approximately 100 tons of raw coal during maintenance work on the stirrers in the coal slurry tank of the gasification furnace. At current coal prices, this has helped the company save 90,000 yuan in production costs. It is reported that the agitators in the coal slurry tanks have suffered from corrosion and other issues due to long-term use, posing safety risks to the operation of the facility. Before repairing these agitators, it is necessary to completely remove the coal slurry from the tanks. To avoid waste of this coal slurry, the center conducted discussions and developed a plan for its recovery: the removed slurry is dried to remove excess water, after which it is transported to the coal storage bins for reuse. Currently, domestic coal prices remain high, putting certain pressure on the company’s operations. The measure of recycling coal slurry helps to further reduce production costs, making a positive contribution to the company’s efforts to cut costs and improve efficiency.
