What areas in the sulfur recovery unit need to be protected from freezing in winter?
Attention must be paid to the acidic water discharge line, the liquid sulfur line, and the acidic gas line.
Check the steam trap to ensure there is no water left in it, otherwise it may freeze and crack

Pay attention to preventing freezing and condensation in the dead corners of the water lines and steam lines, as these areas are prone to cracking due to freezing. 2. Strengthen the inspection of steam traps, and address any blockages promptly. 3. Pay attention to the temperature after steam drainage to prevent liquid sulfur from failing to dissolve, which could lead to pipeline blockages. 4. The circulating water in the fan should be drained promptly and the system cleaned to prevent pipeline freezing and cracking.
Sulfur recovery is generally implemented as a combined unit with acidic water stripping; in winter, the pressure and flow measurement devices related to the acidic gas stream in the acidic water stripping process are prone to malfunction, so proper insulation measures must be taken； The person upstairs mentioned the circulating water for fans; our fans do not have circulating water cooling ； Anti-freezing measures must be in place for the low-point vent of the acidic gas line; otherwise, a leak can be very dangerous.
