What is the current SO2 concentration level in the exhaust gases from sulfur recovery? (For the best and worst cases,) it is necessary to identify the areas where process improvements are needed in order to meet the requirements of GB31570-2015 (Emission Standards for Pollutants in the Petroleum Refining Industry).
Generally, it's 400, 200, 100 I guess. These days, new projects are generally designed with 200 as the standard

Improvement measures: Optimize operations ； Stable inlet device acid gas flow rate ； Keep track of production changes in upstream facilities in a timely manner ； Regular calibration of online analyzers ； Introduce new technologies in a timely manner; exchange experiences periodically with peers using similar equipment.
As far as I know, the usual price is around four to five hundred; there are also options at two to three hundred. Generally, if modifications are required, the cost is considered to be within 100. We have the relevant power wave alkaline cleaning technology that can be used for such modifications.
