DPR & CMA Data on Sodium sulphide by barium sulphate process

The project for the production of sodium sulphide via the barium sulphate process involves utilizing barium sulphate as a crucial raw material to produce sodium sulphide, a widely used chemical in various industries. Sodium sulphide is essential for its applications in textile, paper, and leather processing, as well as in the manufacturing of dyes and pharmaceuticals. The barium sulphate process offers a unique method to efficiently convert this sulfate into sodium sulphide with lower energy requirements compared to traditional methods. The production process includes the reduction of barium sulphate using sodium carbonate or sodium sulfite under controlled conditions to yield sodium sulphide and barium carbonate as a by-product, which can also be reused or sold. This environmentally friendly approach aims to minimize waste and improve sustainability in chemical manufacturing. Furthermore, with the increasing demand for sodium sulphide in emerging markets, the project holds strong potential for profitable returns. The market for sodium sulphide is driven by growth in several sectors such as water treatment, pulp and paper, and mining industries, making this an advantageous venture for stakeholders involved. Significant research and development efforts have been directed towards improving process efficiencies and reducing costs, thereby enhancing the competitiveness of sodium sulphide produced through the barium sulphate method in the global market. As the chemical industry continues to evolve, innovations in production methodologies will ensure that sodium sulphide remains a critical component in numerous applications.

• Growing demand in the textile industry due to increased production.
• Expansion of the paper manufacturing sector requiring bleaching agents.
• Rising use in water treatment applications and environmental sustainability.
• Increased interest in alternative and eco-friendly production methods.

Total capital investment ranges from ₹1,500,000 to ₹30,000,000 depending on the scale of operation. This covers plant and machinery, civil work, pre-operative expenses, and working capital. Larger scales require proportionally higher investment but typically offer better returns.

At the larger investment scale, the expected break-even is approximately approx. 5 years at approximately 80.00% capacity utilisation. Smaller setups may reach break-even sooner due to lower fixed costs relative to the capacity.
