Yellow phosphorus factory renovation and upgrading guide

Yellow phosphorus is an important basic product in the phosphorus chemical industry (excluding phosphorus fertilizers), mainly used for the production of phosphides such as phosphoric acid and phosphorus trichloride. The energy consumption of yellow phosphorus mainly consists of electricity consumption and coke consumption. The main problems with energy consumption include low grade raw materials leading to increased electricity consumption, insufficient comprehensive utilization of exhaust gas, and insufficent utilization of thermal energy. There is great potential for energy-saving and carbon reduction transformation and upgrading.

Yellow phosphorus factory renovation and upgrading guide:

1.Strengthen the development and application of cutting-edge technologies, cultivate benchmark demonstration enterprises

Promote the coupling innovation of phosphorus chemical industry to produce yellow phosphorus and Coal gasification, industrialize the reduction reactor, burner and other key technical equipment, improve the utilization rate of medium and low grade phosphate rock resources, and accelerate industrial innovation and upgrading through phosphorus coal joint production.

2.Accelerate the popularization and promotion of mature processes, and orderly promote transformation and upgrading

(1)Green technology process. Accelerate the promotion of yellow phosphorus tail gas sintering technology for medium and low grade phosphate ore and powder ore, improve the grade of incoming raw materials, and reduce power consumption. Accelerate the application of phosphorus furnace gas dry dust removal and continuous sludge phosphorus recovery technology. Promote the purification and purification of phosphorus furnace exhaust gas using catalytic oxidation and temperature and pressure swing adsorption methods for the production of chemical products.

(2)Energy system optimization. Optimize the yellow phosphorus furnace body with high insulation materials to reduce heat loss.

(3)Utilization of residual heat and pressure. The tail gas of the phosphorus furnace is used for raw material drying and sludge phosphorus recovery, and the combustion heat of the recovered tail gas is used to generate steam and power generation.
