Innovative Technology for Potash Recovery from Incineration Boiler Ash

In the sugar and distillery industries, Incineration Boilers are essential for meeting Zero Liquid Discharge (ZLD) norms and managing concentrated spent wash. However, these boilers come with high capital (CAPEX) and operational (OPEX) costs, often requiring additional equipment like turbines to justify their installation.

One of the major challenges associated with these boilers is the management of fly ash, a by-product that can contribute to environmental pollution if not handled properly. This ash contains potassium-rich salts (Potash), a valuable resource that has largely been underutilized due to the lack of efficient recovery technologies.

At CPS, we have developed a groundbreaking technology to recover high-purity Potash (K₂SO₄) from incineration boiler ash, transforming waste into a valuable resource while addressing environmental concerns.

The Problem: Fly Ash and Lost Opportunities

Fly ash generated by incineration boilers is often disposed of in ways that do not maximize its potential:

– Used as a potash additive in fertilizers, either directly or in granulated form.

– Sent to brick-making or cement industries as a filler material.

While these methods provide some utility, they fail to extract the full value of the potassium-rich salts present in the ash.

Our Solution Recovering High-Purity Potash

Our innovative process extracts Potash (K₂SO₄) in its purest form—white crystalline FCO-grade Potash with over 99% purity and high water solubility. This process not only recovers a valuable resource but also ensures that the residual ash can be used more effectively in other industries.

Key Benefits of Our Technology

Cost-Effective : Minimal modifications to existing systems, with easy installation and retrofitting.
High-Value Recovery : Produces FCO-grade Potash (K₂SO₄), a valuable fertilizer with lucrative market potential.
Environmental Sustainability : Reduces waste and pollution by recovering Potash and utilizing residual ash effectively.
Enhanced Brick Quality : Residual ash produces high-strength, durable bricks, adding value to the construction industry.
Self-Sustaining : The recovery process is profitable, making the plant setup economically viable.

Applications of Recovered Potash

The high-purity Potash (K₂SO₄) recovered through our process is ideal for:

– Fertilizers: Directly usable as a bagged fertilizer, enhancing crop yield and soil health.

– Industrial Use: Suitable for various industrial applications requiring high-purity Potash.

The Process: Simple, Efficient, and Sustainable

1. Ash Mixing and pH Balancing:

– The ash is mixed with water to a specific concentration.

– The high pH of the solution is balanced by adding acid.

2. Separation and Filtration:

– A separation catalyst is used to isolate the Potash-rich solution from the ash.

– The mixture is passed through a high-pressure filter, separating the ash and leaving behind a Potash-rich liquid.

3. Concentration and Crystallization:

– The Potash-rich liquid is concentrated using a Multi-Effect Evaporation Plant.

– The concentrated solution is then processed in an Evaporative Crystallizer to form white crystalline Potash.

4. Purification and Recovery:

– The crystals are separated using a centrifuge.

– Traces of organics are removed in a reactor using a catalyst at a specific temperature.

5. Residual Ash Utilization:

– The salt-free residual ash is ideal for brick-making, producing bricks with higher strength and durability compared to conventional red bricks.
