Basic Chemicals

1. Industry Demand

Basic chemical production including sulfuric acid synthesis, nitric acid concentration and soda ash manufacturing features strong corrosive media, high temperature & pressure and drastic working condition fluctuations. Heat exchangers require premium corrosion resistance, reliable sealing, high heat transfer efficiency and structural stability to eliminate leakage risks, stabilize reaction status, ensure high product purity and support long-term safe production.

2. Core Working Stations

Core scenarios cover high-temperature flue gas cooling for sulfuric acid synthesis, high-concentration nitric acid concentration heat exchange, high-pressure cooling and mother liquor preheating for soda ash carbonation, calciner waste heat recovery and special tail gas cooling. Widely applied in bulk basic chemical production, it improves product quality, reduces energy consumption and ensures stable and safe operation.
