Calcium thiosulfate is an inorganic compound that is utilised as a liquid fertiliser for agriculture. It provides essential calcium and sulfur to crops. It is used in water treatment as a dechlorination agent and in other industrial processes. The growing focus on sustainable agricultural practices and efficient nutrient management leads to the increasing demand for calcium thiosulfate in speciality chemicals and the agriculture sector.
 

Industrial Applications of Calcium Thiosulfate

Calcium thiosulfate finds its applications as a fertiliser, dechlorinating agent, and complex-forming agent.

• Agriculture: Calcium thiosulfate is utilised as a liquid fertiliser to correct calcium and sulfur deficiencies in soil and plants.
  • Nutrient Supply: It provides calcium that is important for cell wall formation, root development, and nutrient uptake, and thiosulfate sulfur that is required for protein synthesis, chlorophyll production, and healthy crop growth.
  • Soil Amendment: It works as "liquid gypsum" to improve soil structure, porosity, and water infiltration, and helps in leaching harmful soil salts in acidic or sodic soils.
  • Nitrogen Stabiliser: It is used as a nitrogen stabiliser and helps to reduce ammonia volatilisation from surface-applied urea, which improves its efficiency.
• Water Treatment: It is used as a dechlorination agent to remove chlorine from tap water, wastewater, and aquaria. It's a safer and more eco-friendly option compared to some other dechlorinating agents.
• Flue-Gas Desulfurization (FGD): It is used in some advanced FGD processes for removing sulfur dioxide from industrial emissions.

Feedstock for Calcium Thiosulfate and Its Market Dynamics

The feedstock for calcium thiosulfate production varies depending on the specific manufacturing process chosen.
 

Feedstock for Production from Calcium Chloride:

The major feedstock for this process is calcium chloride and sodium thiosulfate.

• Calcium Chloride: It is commonly produced as a by-product of the Solvay process (soda ash production) or from the neutralisation of hydrochloric acid with calcium carbonate (limestone) or calcium hydroxide. The industrial procurement of calcium chloride is influenced by the demand for soda ash, energy costs for its production, and the availability of natural brines.
• Sodium Thiosulfate: It is produced by reacting sodium sulfite with sulfur, or from by-products of sulfur dioxide scrubbing processes in industrial emissions control. Its costs and availability are affected by sulfur prices, sodium sulfite costs, and the demand from its downstream industries like photography, dechlorination, and gold extraction.
   

Feedstock for Production via Metathesis Reaction:

The primary feedstock for this process is ammonium thiosulfate and either calcium hydroxide or calcium oxide.

• Ammonium Thiosulfate: It is produced by reacting ammonia, sulfur dioxide, and water, often with elemental sulfur. Its price is influenced by sulfur and ammonia prices, and the demand from its primary use as a fertiliser.
• Calcium Hydroxide/ Calcium Oxide: Calcium Hydroxide is produced by reacting calcium oxide (quicklime) with water, while calcium oxide is produced by calcining (heating) limestone (calcium carbonate) at high temperatures. Their prices are mainly influenced by the cost of limestone, energy (for calcination), and demand from construction, steel, and water treatment industries.
   

Dynamics Affecting Raw Materials

The dynamics affecting these raw materials are important for the cash cost of production and overall manufacturing expenses of calcium thiosulfate.

• Commodity Price Instability: The prices of calcium chloride, sodium thiosulfate, ammonium thiosulfate, and calcium hydroxide/oxide are affected by market fluctuations, geopolitical events, and supply-demand imbalances.
• Integrated Production Benefits: The producers that have large-scale industrial processes (like chlor-alkali, sulfur recovery, fertiliser production) have a cost advantage in sourcing raw materials.
• Energy Costs: Production of many raw materials (like sodium hydroxide, calcium oxide, ammonium thiosulfate) is energy-intensive, and their production costs are impacted by fluctuations in energy prices.
• Transportation and Handling Costs: The cost of transporting materials like sodium hydroxide or ammonium thiosulfate that require specialised handling adds to their production cost.
   

Market Drivers for Calcium Thiosulfate

The market for calcium thiosulfate is influenced by several factors:

• Growing Demand for High-Efficiency Fertilisers: The increasing global demand for sustainable and efficient agricultural practices that improve crop yield and quality contributes to its market. Its ability to provide essential calcium and sulfur, improve nutrient uptake, and enhance soil structure makes it a valuable additive in modern agriculture.
• Increasing Awareness of Soil Health: The growing awareness among farmers of the importance of soil health and structure boosts its demand further.
• Demand for Water Treatment Chemicals: The rising concerns for environmental sustainability and strict regulations for water quality drive the demand for effective dechlorination agents in tap water, wastewater, and industrial processes.

Calcium Thiosulfate Industrial Manufacturing Processes

This report comprises a thorough value chain evaluation for calcium thiosulfate manufacturing and consists of an in-depth production cost analysis revolving around industrial calcium thiosulfate manufacturing. We will examine two distinct processes for its synthesis.
 

Production from Calcium Chloride:

The manufacturing process of calcium thiosulfate involves a reaction between calcium chloride and sodium thiosulfate. In this process, calcium chloride reacts with sodium thiosulfate in a stirred reactor at temperatures of 45–90 degree Celsius. This double displacement reaction results in the formation of calcium thiosulfate and sodium chloride in solution. The final is separated and concentrated to get pure calcium thiosulfate as the final product.
 

Production via Metathesis Reaction:

In this metathesis process, ammonium thiosulfate solution is added to a slurry of calcium hydroxide (or calcium oxide) in a stirred reactor at 25–85 degree Celsius. This reaction leads to the formation of calcium thiosulfate and volatile ammonia (that is efficiently removed by heating, air sparging, or vacuum). The resulting solution is filtered and purified to get pure Calcium Thiosulfate as the final product.
