Chem Process Systems Pvt. Ltd. is a trusted provider of innovative technology for Potash (K₂SO₄) recovery from incineration boiler ash across India.
With a strong engineering legacy, we help industries convert waste streams from sugar and distillery operations into high-value, FCO-grade potash, enabling both environmental compliance and new revenue generation.
Our registered office is located in Sanand, Gujarat, India.
We transform incineration boiler fly ash into high-purity Potash (K₂SO₄) (>99%), supporting industries in achieving Zero Liquid Discharge (ZLD) goals efficiently.
Highlights
- Patented technology developed in collaboration with CSIR–CSMCRI
- First commercial-scale plant successfully implemented at DCM Shriram, Uttar Pradesh
- Proven solution for sugar and distillery ecosystem integration
The Challenge We Address
- Incineration boilers generate potassium-rich fly ash as a waste by-product
- Conventional disposal methods underutilize valuable potassium content
- High CAPEX and OPEX of ZLD systems require additional value recovery pathways
- Improper ash handling leads to environmental risks and disposal challenges
Our Breakthrough Solution
We offer a fully integrated process to extract, purify, and crystallize Potash (K₂SO₄) from boiler ash, converting industrial waste into a commercially viable product.
Features of the Technology
- High Purity Output: FCO-grade Potash (>99% purity, white crystalline form)
- Retrofit Friendly: Minimal modification required for existing plant integration
- Economically Viable: Revenue generation offsets ZLD operational costs
- Zero Waste Approach: Complete utilization of ash residues
- Sustainable Engineering: Supports circular economy and reduced environmental impact
Process Overview
- 1. Conditioning: Fly ash is mixed with water and treated with controlled pH adjustment
- 2. Separation: Potash-rich liquor is isolated using advanced filtration systems
- 3. Concentration: Multi-Effect Evaporation (MEE) increases solution concentration
- 4. Crystallization: Evaporative crystallization forms Potash crystals
- 5. Purification: Centrifugation and refining ensure high product purity
- 6. Residue Management: De-salted ash is utilized in construction-grade brick manufacturing
Benefits
- Converts industrial waste into high-value fertilizer-grade product
- Improves profitability of sugar and distillery operations
- Strengthens ZLD compliance and sustainability goals
- Reduces landfill dependency and environmental burden
- Enables reuse of residual ash in construction applications
Applications of Recovered Potash
- Agriculture: High-quality fertilizer for improved soil fertility and crop yield
- Industrial Use: Suitable for chemical and specialty-grade potassium sulfate applications
