Sour gas enters the absorber through pipelines and contacts intensively with the Chelated iron solution. Hydrogen sulfide (H2S) in the sour gas is absorbed by the solution. The purified gas exits from the top of the absorber and goes through gas-liquid separation; the separated liquid is recovered for reuse, while the clean gas is delivered via pipelines.
The rich desulfurization solution discharges from the bottom of the absorber and flows into the regenerator. Inside the regenerator, the rich solution is regenerated with air under ambient temperature and atmospheric pressure, and sulfides in the solution are oxidized into elemental sulfur. The rich solution is thus regenerated into lean solution.
In the regenerator, sulfur particles are lifted by air bubbles to the liquid surface, forming a sulfur foam layer. The sulfur foam overflows into a sulfur foam tank, and is then fed into a filter press to separate sulfur particles from the desulfurization solution. The separated solution enters a filtrate tank, and is then pumped by a filtrate pump into the lean solution tank for recycling reuse.
Suitable for large flow rates with high H2S treatment efficiency compared with conventional processes.
The spray section adopts bidirectional nozzles, effectively increasing the actual number of spray layers.
Short construction period and simple operation and maintenance.
Particularly suitable for low-circulation H2S removal systems.
Multi-point and multi-layer spray gun distribution with accurate quantitative control ensure fast response at any operating load.
