This article introduces a new and efficient process and device for acid gas recovery in refining and chemical enterprises-hydrogen sulfide dry acid production process and device. The main problems and failures in the operation of the device are explained, and the related problems and the causes of the failures are analyzed in a targeted manner. In the technical transformation of the base and lining of the acid gas incinerator and the adaptive transformation of the electric defogging system, the development and application of new all-glass steel cooling tower, the implementation of new technologies to improve the efficiency of defogging and acid separation, and the mass transfer and heat transfer efficiency of the process medium, The application of "three units" technology to improve the technical and economic level of the device, the use of sodium-alkali neutralization process to treat the wastewater and tail gas of the device, have unique insights and successful experience, and continue to carry out technical improvement, innovation, integration and application of results for the device. The safety, stability, long-term, economic operation and design and improvement of related fields have important guidance and reference significance.
