Chlor-Alkali & PVC

1. Industry Demand

Chlor-alkali and PVC production involves electrolyzer cooling, VCM synthesis, caustic soda heating, hydrochloric acid stripping and polymerization temperature control. It features highly corrosive, toxic media, high temperature and high pressure with strict anti-leakage requirements. Heat exchangers must deliver superior corrosion resistance, pressure resistance, reliable sealing and high efficiency to stabilize reaction temperature, eliminate leakage hazards and ensure safe and high-quality production.

2. Core Working Stations

Core working scenarios include brine electrolysis cooling, high-pressure VCM synthesis heat exchange, high-temperature caustic soda heating, hydrochloric acid stripping waste heat recovery and precise PVC polymerization temperature control. Covering the full chlor-alkali and PVC production process, it realizes safe operation, stable product quality and energy conservation.
