A sour gas emission management system and method

Abstract

The application discloses an acid gas emission management system and method, and relates to the technical field of acid gas emission management, which comprises a control module, a heavy metal removal module and an adjusting module, wherein the heavy metal removal module comprises a three-phase separation tank; the control module controls the temperature and pressure of the three-phase separation tank in a first temperature range and at a preset pressure respectively, so that hydrogen sulfide in the acid gas reacts with ammonia gas in the three-phase separation tank to generate non-gaseous ammonium hydrosulfide, and heavy metals in the acid gas react with sulfides in the system to generate sulfide solid phase; the three-phase separation tank performs three-phase separation, discharges the separated solid phase and liquid phase, and introduces the separated gas phase into an acid gas flare head for combustion; and the adjusting module adjusts the combustion temperature of the acid gas flare head to be in a second temperature range, and the second temperature range is a temperature range for inhibiting the generation of gaseous sulfur. The application can reduce or avoid the generation of sulfur particles, ammonium sulfate particles and sulfur trioxide.
