treatment of sour gas from sour water stripper
(OP)
In our refinery, the sour gas from the sour water stripper is sent to the sulfur recovery plant.
It make trouble to the sulfur recovery plant.
(plugging and corrosion)
Is there any new process that can treat this sour gas stream?
The composition os this stream is:
H2S: 40%
NH3: 30%
With balance N2, H2O,HC
It make trouble to the sulfur recovery plant.

The other alternative is to remove the ammonia source from the feed stream, but then of course, it must be treated elsewhere.

The key is the RF temperature and the two patents on the process cite 1250C as the required temperature. Every burner and RF has its own characteristics and some manage at lower temps. It depends on the burner and mixing characteristics, and the relative load of SWS gas to AG.
Testing for NH3 breakthrough at the WHE outlet is the only way of determining your RF capability.
There is a detailed paper on this topic available on our website.

Typically that stream is ~30% H2S also, so in most cases, burning it directly without further downstream treatment would violate environmental regulations/permits for SO2 emissions.

There are ways to handle SWS gas successfully in the SRU as is done in countless refineries around the world. The key is sufficent temperature and mixing in the reaction furnace.

A processing step as the one above should be economically and environmentally weighed against others such as incineration and SRUs as JohnSames advises.
