Technical Specification for the Design of the Ammonia-Based Desulfurization Unit Following the Sulfur Recovery Super Claus Process

1 Quality requirements for anhydrous sulfuric acid: specifications regarding whether it is in solid or liquid form, as well as requirements for purity or impurity levels. There are **standards** in place; these standards represent the minimum requirements, and the actual quality level can be higher than those standards. It is recommended to establish standard methods for the analytical testing of sulfuric acid an. 2 For the control criteria for flue gas purification, in addition to the **specified pollutant emission standards, an ammonia escape criterion must also be added. It is recommended to establish standards for analytical testing methods of ammonia escape. Ammonia is considered a type of VOC, and its control is necessary. 3 The crystallization process of anhydrous sulfuric acid is carried out in a closed environment, but the bagging process is done in an open area; it is recommended to control noise and airborne particulates. 4 The sulfuric acid crystallization process does not consume water; it is recommended to set limits on power consumption or energy usage. 5 Detection requirements for CEMS.
