With five state-of-the-art manufacturing facilities and a legacy of process innovation, Raj Process is helping industries achieve Zero Waste while creating new revenue streams in the bio-fertilizer sector. What is Industrial Granulation? Granulation is the process of particle enlargement, where small particles or powders are gathered into larger, permanent aggregates. For industrial by-products, this is essential for: Improved Flowability: Fine powders often clog machinery and are difficult to transport. Granules flow easily through industrial dispensers and agricultural seed drills. Controlled Release: In fertilizers, granules ensure that nutrients are released slowly into the soil, preventing “nutrient leaching.“ Dust Reduction: Eliminating fine dust reduces respiratory hazards for workers and prevents material loss due to wind during field application. The Raj Process Technical Advantage At Raj Process, we don't believe in “one-size-fits-all.“ Our granulation plants are engineered based on the specific chemical and physical properties of your feedstock. 1. High-Precision Pan & Drum Granulators Depending on the required throughput, we offer high-efficiency Disc (Pan) Granulators for precision size control and Rotary Drum Granulators for massive industrial volumes. Custom Scrapers: Our systems feature adjustable scrapers to prevent material buildup, ensuring a smooth, continuous process. 2. Advanced Moisture & Binder Management The “secret“ to perfect granules lies in the binder-to-powder ratio. Our automated dosing systems precisely inject water or organic binders (such as molasses) to create strong, spherical granules that don't crumble during transport. 3. Integrated Energy-Efficient Drying Freshly formed “green“ granules contain moisture that must be removed. We integrate Fluid Bed Dryers (FBD) or Rotary Dryers that utilize waste heat from your existing boilers, drastically reducing operational costs (OPEX). Major Applications – Turning Waste into Gold 1.

With five advanced manufacturing facilities and a legacy of process engineering, Raj Process is redefining the circular economy. Understanding CCU – From Waste to Value What is CCU?Carbon Capture and Utilization (CCU) is the process of capturing Carbon Dioxide ($CO_2$) directly from industrial flue gases—such as those from distilleries, power plants, and refineries—and converting it into useful products. CCU vs. CCS: The Profitable Alternative Unlike Carbon Capture and Storage (CCS), which involves pumping $CO_2$ underground at a significant cost, CCU focuses on valorization. By treating $CO_2$ as a feedstock rather than a waste product, industries can create new revenue streams that often offset the entire cost of the capture plant. The Raj Process CCU Technology Suite At Raj Process, we understand that no two flue gas streams are the same. We offer a diverse range of capture technologies tailored to specific industrial profiles. 1. Advanced Chemical Absorption (Solvent-Based)This is the gold standard for high-volume emissions. We utilize specialized amine-based or potassium carbonate-based solvents to selectively “scrub“ $CO_2$ from flue gases.Efficiency: Achieves 95% to 99% recovery.Application: Ideal for large-scale ethanol plants and thermal power units. 2. Membrane SeparationFor plants with space constraints or lower flue gas volumes, our membrane systems offer a compact, energy-efficient solution. This technology uses semi-permeable materials to separate $CO_2$ based on molecular size and solubility. 3. Adsorption & VPSA SystemsUsing solid adsorbents like Zeolites or Activated Carbon, our Vacuum Pressure Swing Adsorption (VPSA) systems trap $CO_2$ molecules. This is a dry process, ideal for applications where water usage must be minimized. 4. Cryogenic Purification & Lique faction Once captured, the $CO_2$ must be purified. Raj Process systems deliver 99.9% purity, meeting the stringent requirements for:ISBT (International Society of Beverage Technologists) standards for carbonated drinks.

The spentwash Challenge in Modern Distilleries In the wake of India’s E20 Ethanol Blending Mandate and the global push for sustainability, the ethanol industry is booming. However, this growth brings a massive environmental hurdle: Spentwash. Also known as vinasse or distillery slop, spentwash is the dark, viscous, and highly acidic liquid left after the distillation of molasses or grain. With a high BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand), untreated spent wash can devastate local ecosystems. Raj Process Equipments provides the definitive solution with our Next-Generation Spent wash Dryers, designed to achieve 100% Zero Liquid Discharge (ZLD) while creating a revenue-generating by-product. Why Traditional Waste Management is Failing For decades, distilleries relied on “Lagooning“ or dilution. These methods are no longer viable in 2026 due to: Strict Regulatory Norms: CPCB and SPCB have mandated absolute ZLD for all distilleries. Groundwater Contamination: Leaching of salts and organic matter into the water table. High Land Footprint: Massive lagoons occupy valuable industrial land. Odor and Public Health: Foul smells lead to community friction and legal liabilities. The Raj Process Spentwash Dryer eliminates these issues by reducing waste volume by over 80%, converting a problematic liquid into a dry, easy-to-handle powder. The Raj Process Spentwash Drying Mechanism Our system is not a simple heater; it is a sophisticated thermal engineering platform. 1. Advanced Evaporation & Concentration Before drying, the spentwash is concentrated in our Multi-Effect Evaporators (MEE) or Mechanical Vapor Recompression (MVR) systems. This reduces the moisture content to a level where thermal drying becomes highly energy-efficient. 2. Thermal Drying & Solidification The concentrated wash is fed into the Raj Process Dryer. Utilizing controlled hot air or steam, we flash-dry the material. The result is a fine, free-flowing powder that retains all the nutrient value of the original waste but without the water weight. 3. Patented Energy Recovery Energy is the highest cost in drying. Raj Process systems are engineered with Waste Heat Recovery (WHR) units. We recycle the latent heat from the exhaust vapors to pre-heat the incoming spentwash, cutting fuel costs by up to 25%. 4. Emission & Odor Control (The Scrubber System) To address the “foul odor“ problem, our dryers are equipped with integrated venturi scrubbers and activated carbon filters. This ensures that the air released into the atmosphere is clean, odorless, and compliant with air quality standards. The Economic Value – Waste into Resource 1. Production of Bio-Potash Fertilizer The dried powder from a Raj Process dryer is a “Gold Mine.“ India currently imports a vast majority of its Potash. By drying spentwash, distilleries produce Bio-Potash, which can be sold to farmers or fertilizer companies at lucrative rates (₹15,000 to ₹25,000 per tonne). 2. Fuel Substitution In certain plant configurations, the dried solids have a Calorific Value of approximately 2,200 to 2,500 kcal/kg. This allows the powder to be co-fired in the distillery's boiler, reducing the consumption of expensive coal or bagasse. 3. Drastic Logistics Savings By reducing the volume of waste by over 80%, the cost of transporting waste for composting or disposal is virtually eliminated. 100 truckloads of liquid waste are reduced to just 20 truckloads of high-value powder.

RajVapor Operating Modes Molasses Mode (BMSW): Features an integrated degasser and ammonia stripper to remove volatile organic compounds before they foul the heat exchanger tubes. Grain Mode (Thin Slop): Utilizes Forced Circulation (FC) or Falling Film (FF) configurations to handle high-solid feeds (up to 40% solids) without scaling. Mechanical Vapor Recompression (MVR): For large plants (above 100 KLPD), we offer MVR technology, which uses electricity to compress vapors, virtually eliminating the need for fresh steam in the evaporation stage. The Raj Process Advantage – Why We Are the Best 1. Asia’s First Innovations: Raj Process is the pioneer behind Asia’s first 20 TPD CBG plant and has set benchmarks in integrated spent wash drying. Turnkey EPC Execution: From the first drawing (PID) to the final commissioning, Raj Process provides a single-window solution. We eliminate the “interface risk“ often found when buying fermentation from one vendor and evaporation from another.
