Study on the Product Structure Optimization of Hot Process Phosphate Based on Comprehensive Utilization of Yellow Phosphorus Tail Gas
After desulfurated by electric furnace process, yellow phosphorus tail gas could be used to generate electricity or produce C1 chemical products. Through comparing the restraining factors and feasibility of the above two comprehensive utilization methods, the generation of using yellow phosphorus tail gas is considered as a more advantageous and developing comprehensive utilization way. Moreover this paper recommends a cascade recycling technology which focuses on the generation and recycling heat energy. Based on the above, the downstream products structures of yellow phosphorus can be divided into three kinds, Class A, B and C. Through comparative analysis, Class A is thought to be the best structure that could make the complete recycling of tail gas come true and recycle the waste heat to gain vapor which replaces coal-fired boiler.
