What is Chlorine?

Chlorine is a highly reactive chemical element with the symbol Cl and atomic number 17, belonging to the halogen group in the periodic table. It exists as a greenish-yellow diatomic gas (Cl₂) at room temperature and is well known for its pungent odor and strong oxidizing properties. Commercially, chlorine is produced through the electrolysis of brine (sodium chloride solution), yielding chlorine gas, hydrogen, and caustic soda as co-products. Chlorine is non-flammable but highly reactive, making it essential in disinfection, chemical synthesis, and industrial applications. Its key properties include strong bactericidal action, high solubility in water, and ability to form compounds with most elements. Chlorine plays a critical role in the production of polyvinyl chloride (PVC), solvents, chlorinated intermediates, and pharmaceuticals. It is also extensively used in water purification, sanitation, pulp & paper bleaching, and agrochemical production. Due to its effectiveness in safeguarding public health through disinfection, chlorine remains indispensable in modern industry.

Chlorine Production Plant: Key Highlights

• Process Used: Electrolysis of brine
• End-use Industries: Chemicals, water treatment, plastics (PVC), pharmaceuticals, pulp & paper, and agrochemicals industries
• Applications: Used in PVC production, bleaching agents, disinfectants, solvents, hydrochloric acid, and chlorinated organic compounds production

A chlorine production plant is a specialized facility designed to extract chlorine gas from brine through controlled electrochemical processes. The plant consists of brine preparation units, electrolyzers, gas treatment and drying systems, hydrogen recovery units, caustic soda concentration units, and chlorine compression and storage systems. During electrolysis, sodium chloride is decomposed into chlorine gas, hydrogen gas, and sodium hydroxide, which are all commercially valuable. Advanced plants employ membrane cell technology due to its higher energy efficiency and lower environmental impact compared to mercury-based processes. Machinery includes salt dissolvers, filtration systems, electrolyzers, drying towers, absorption columns, compressors, and scrubbers. Strict safety, environmental compliance, and monitoring systems are crucial due to chlorine’s hazardous nature. End products are distributed as liquefied chlorine cylinders, bulk tonnage containers, or piped gas to downstream industries.

Chlorine Industry Outlook 2025:

The chlorine market is primarily driven by its widespread use in polyvinyl chloride (PVC) production, a material essential in construction, automotive, and packaging. Demand for chlorine in water treatment and sanitation is also rising globally, particularly in urbanizing regions, as governments strengthen policies and launch initiatives for safe drinking water and wastewater treatment. For instance, the Government of Kerala’s Haritha Keralam Mission started a state-wide campaign in August 2025 to guarantee the supply of safe drinking water and prevent the spread of water-borne diseases through water-source chlorination efforts. As part of this campaign, local self-government organizations will provide the chlorine tablets needed for chlorination. The pharmaceutical industry also relies on chlorine derivatives for antibiotics, anesthetics, and intermediates. Emerging trends include the expansion of green building materials, boosting PVC consumption, and increasing focus on advanced disinfection solutions in healthcare and municipal infrastructure. Competitive advantages of chlorine production include co-product generation of caustic soda and hydrogen, which enhances plant profitability. However, the industry faces challenges such as stringent environmental regulations, potential health hazards during handling, and high energy requirements of electrolysis. Sustainability factors include the adoption of membrane cell technology, which minimizes mercury emissions and energy consumption. The industry response has been proactive, with companies investing in modernized chlorine facilities, integrating renewable power sources, and developing safer logistics for chlorine transport.
