| Abstract: | The recycling of yellow phosphorous tail gas rich in carbon monoxide is related to energy conservation and environment protection.Based on the analysis of existing technologies for the recycling of yellow phosphorous tail gas,a novel continuous process was developed by combining the resources recycling of yellow phosphorous tail gas with formic acid production,which made phosphoric acid acidification method as the core and could produce formic acid with high quality and low cost on the basis of considering the high and variable viscosity of system and the rationality of energy utilization.At the same time,a multilevel acidification reactor was also designed by integrating the reaction,heating and condensation reflux,which was divided into several reaction regions and equipped with different stirrers.The novel acidification reactor as the core equipment had the advantages of compact structure,energy conservation and wide adaptability. |
