Transformation of low-temperature waste heat recovery in the drying and absorption process of sulphuric acid plant
The process flow,key points of transformation and main equipment situation of low-temperature waste heat recovery and utilization in the drying and absorption process of sulphuric acid production unit are introduced.The key to the low-temperature waste heat recovery system lies in material selection and process control.Based on the example of a company's low-temperature waste heat recovery renovation of the drying and absorption process,the operating costs of the equipment before and after the renovation are compared.After the renovation,the 300 kt/a sulphuric acid production plant can increase its annual income by more than 30 million yuan,and the economic benefits are very considerable.
