Chlor Alkali

Process solutions used in the chlor alkali industry must provide excellent resistance to the highly corrosive chemicals used in the production of chlorine, sodium hydroxide (caustic soda) and hydrogen gas. Chlor alkali chemicals will react harshly to metals, causing contamination, corrosion and hazards, in some cases, even violent chemical reactions. In addition, the chemical changes after undergoing electrolysis or other processes can cause expansion, putting extreme pressure on joints and welds. Leaks can lead to trapped gas, which can expand and break seals. All these factors mean the chlor alkali market requires non-conductive materials in its process systems that can withstand highly corrosive environments and elevated temperatures, in addition to stress from chemical reactions and electrolytic cells.

Dual laminate products used in the chlor alkali industry are constructed by combining a thermoplastic inner layer and a fiberglass-reinforced plastic (FRP) outer layer. The thermoplastic layer provides excellent resistance to a wide range of corrosive chemicals, including chlorine and sodium hydroxide, while the FRP layer provides additional strength and durability. Dual laminate products are a cost-effective and reliable solution for creating specialized components and equipment to last during long periods, from production to transport to storage.

Ceramics are commonly used in the chlor alkali industry due to their excellent resistance to corrosion, high temperature and wear. The use of ceramics includes storage, insulation and catalysts in chemical reactions, and various layers of linings can work together for added protection against leaks and product contamination.
