The inlet of stage 1 of the compressor is severely contaminated with sulfur.

Process description: Alkaline desulfurization; the pressure at the desulfurization outlet is 40 kPa. Gas flow path: Roots blower ~ cooling tower ~ desulfurization tower ~ cleaning tower ~ compressor. The gas at the compressor inlet (exit of the cleaning tower) is severely contaminated with sulfur. The problem lies with the desulfurization cooling water. 1. The quality of the circulating water is poor; the job analysis indicates approximately 2 titers. 2. The circulating water cannot be replaced. Are there any other ways to solve this problem?
A Claus sulfur recovery unit is installed in front of the compressor, that is, after the cleaning tower.
An electrostatic precipitator is installed in front of the compressor, that is, after the cleaning tower.
It is recommended to focus on checking whether a bypass line is in use in the desulfurization tower, as well as the gas-liquid distribution and mist entrainment in both the desulfurization tower and the cleaning tower

This is a common phenomenon. First, it is necessary to improve the operation management of electrostatic precipitators. Second, the scrubber tower located after the desulfurization tower should have its packing and distributors checked regularly to ensure effective cleaning. Third, regular cleaning of the valves in Section 1 is essential; there are no other immediate solutions for this issue.
It’s caused by severe liquid carryover; it’s recommended to tidy up several columns! Separating water in imported water coolers and separation units: victory:
The problem lies in the design of the cleaning tower behind the desulfurization tower, where liquid carryover occurs. It’s fine once it’s fixed. It’s convenient to provide the conditions so I can prepare a plan for you.
I don’t dare; it would be troublesome if it gets blocked.
Consider installing an electrostatic coking removal tower after the Roots blower inlet and the desulfurization tower.
It is recommended to carry out timely technical upgrades, as this represents a safety hazard
