    Study Notes

    Sodium Chloride (AR & IP Grade)

    • Sodium chloride, also known as common salt, is a very old chemical used since ancient times
    • It's a vital food ingredient and used extensively in various industries, including pharmaceuticals.
    • Sodium chloride is a key component in making sodium compounds like sodium carbonate, sodium sulphate, and sodium metabisulphate.
    • High-purity sodium chloride is used in laboratory analyses and in IV fluids.
    • Sea salt is the cheapest form but contains impurities like magnesium sulphate, magnesium chloride, and calcium sulphate that limit its uses in specific industries.

    Market Potential

    • High-purity sodium chloride is crucial in chemical labs, with the combined demand from many labs being substantial.
    • Industrial-grade sodium chloride, (IP Grade) is important in IV (intravenous) fluids, and the demand for this product continues to grow.
    • There isn't precise data on precise market size but there's a growing demand.

    Installed Capacity

    • Recommended installed production capacity for AR-grade sodium chloride is 72.0 metric tons per year.
    • Recommended installed production capacity for IP-grade sodium chloride is 48.0 metric tons per year.
    • The combined installed capacity is 120.0 metric tons per year.

    Raw Materials

    • The key raw materials are common salt, calcium oxide, and hydrochloric acid.
    • These raw materials are readily available locally from chemical suppliers.

    Manufacturing Process

    • Sea salt (with impurities like calcium sulphate, magnesium sulphate and magnesium chloride) is the starting material.
    • Impurities are reduced by washing
    • The filtered brine is heated to crystallize the sodium chloride.
    • The product is then further processed to produce AR (analytical reagent) grade or IP (pharmaceutical grade).

    • The study outlines the specific equipment required for this production unit.
    • Types including 250-liter drums, evaporators, centrifuges, driers, pumps, boilers, and laboratory equipment are included in the specifications

    Location and Infrastructure

    • Key factors for choosing a location include raw material availability, market access, and readily available infrastructure (cheap skilled labor).
    • Infrastructure facilities and labor are also important considerations.
    • Power needs 25 HP

    Project Cost and Finance

    • Detailed cost breakdown is included, including land, building, plant, machinery, and pre-operational costs.
    • The project's total cost is detailed.
    • The means of financing are also explained. The study assesses required working capital for a yearly operation.

    Annual Operating Expenses

    • The projected annual operating expenses of the production unit are broken down by raw materials, packaging, utilities, labor, factory overheads, and admin expenses.
