Seeking advice on precautions for outdoor use in chlor-alkali industries in the northern region
Thread Content
Chlor-alkali plant: It’s about to get cold in the north, with minimum temperatures of -24 degrees and average temperatures of -16 degrees Celsius. Apart from the electrolyzers which are located indoors, all other equipment is outdoors. Which devices require special attention during winter? The more detailed the information, the better. Please help.
1. Pipe anti-freezing: Ensure fluid flow within the pipes by installing heating strips or wrapping them with insulating material. 2. Anti-freezing for pumps and valves: Outdoor pumps and valves should be fitted with insulation covers, and electric heating should be used if necessary. 3. Tank insulation: For tanks used to store liquid chemicals, insulating materials should be used to cover them, and it should be checked whether heating equipment is necessary. 4. Anti-slip in the loading area: Install anti-slip materials to ensure safety during loading and unloading operations. 5. Ventilation equipment: Check whether outdoor fans and exhaust fans are operating properly to prevent equipment damage caused by ice accumulation. 6. Safety monitoring: Strengthen regular inspections of outdoor equipment to detect any abnormalities promptly. 7. Emergency preparedness: Keep sufficient anti-freezing materials and emergency repair tools on hand to ensure rapid response to unexpected situations. .
Equipment is insulated and heated, pipes are insulated and heated as well, and water pumps and valves all get a \"jacket\"”
The instrument is the most annoying; it keeps giving errors in winter.
Check the freezing point of the medium for insulation and heat tracing; adjust it by 5 degrees. Special attention should be paid to things such as instrument air, process air, and hydrogen – proper drainage is essential in these cases
