Bromine is a versatile chemical element with applications ranging from pharmaceuticals and flame retardants to oil drilling fluids and water purification. Extracted primarily from brine and seawater, bromine has gained significant industrial importance over the years. Starting a manufacturing business of bromine chemical from sea water offers a highly profitable opportunity for entrepreneurs with access to coastal regions. With a steady demand from multiple sectors, this business model promises long-term sustainability and high return on investment.
Why Invest in Bromine Chemical Manufacturing?
The global demand for bromine is consistently growing, driven by industries such as oil & gas, electronics, agriculture, and sanitation. India, with its extensive coastline and increasing chemical production capabilities, offers an ideal environment to manufacture bromine from sea water. Bromine’s high value, combined with relatively low raw material costs, makes this a lucrative business for those seeking a niche in the specialty chemicals sector.
What is Bromine Chemical from Sea Water?
Bromine is a reddish-brown liquid element that occurs naturally in sea water and underground brine pools. It is extracted using oxidation and distillation processes, followed by purification. The bromine chemical from sea water is then converted into various compounds such as sodium bromide, ethylene dibromide, and hydrogen bromide, which are used in industrial and agricultural applications.

Raw Materials Required
The key raw material for bromine extraction is sea water, which contains approximately 65 parts per million (ppm) of bromine. Other materials include:
-
Sulfuric acid
-
Chlorine gas or bleach (oxidizing agents)
-
Activated carbon
-
Anti-scaling agents
-
Fresh water for washing and processing
Being a naturally available resource, sea water makes the production process cost-efficient, especially near coastal belts.

Manufacturing Process of Bromine from Sea Water
The bromine extraction and purification process involves the following steps:
-
Sea Water Intake – Large volumes of sea water are pumped into storage tanks.
-
Oxidation – Chlorine or bleach is added to oxidize bromide ions into bromine.
-
Air Stripping – Air is bubbled through the solution to strip out elemental bromine.
-
Absorption – The bromine vapor is absorbed in sulfuric acid to form bromine solution.
-
Purification & Distillation – The solution is then distilled to remove impurities and obtain high-purity bromine.
-
Packaging – The bromine is cooled and packaged in corrosion-resistant containers for storage or transport.
This process requires strict monitoring and handling due to bromine’s toxic and corrosive nature.
