Scenario in General : Present & Likely future
PRESENT FUTURE
• Single plant up to 300 KLPD • Reasonably low energy
consumption • Sustainably reduced water
consumption • Recovery of maximum by
products • Relatively low pollution &
Damage to environment • Proven Effluent treatment
packages for Grain & Molasses distilleries
• Further enhanced capacities • Refining & Purification of Co-
products & waste generated from plant
• Maximization of value through Value Added Products
• Integrated Schemes & Models with focus on ZERO LIQUID DISCHARGE with minimum energy consumption.

Energy & water Scenario : Present & Likely future
PRESENT FUTURE
• Overall steam consumption in grain plants 4.5 Kg/lit – 5.0 Kg/lit
• Unused waste energy • 9-10 Lit/Lit fresh water
consumption • Substantial Cooling water
requirement
• Steam consumption @ 4.0 kg/lit
• Waste / Recycle stream will have same temperature as input temperature
• Minimum cooling water requirement
• Lowest possible Fresh Water ; Consumption Limited to Atmospheric losses only

General Concerns…….
• Lower Recoveries
• Higher steam consumption
• Inferior Product quality
• Higher Impure Spirit Cut
• Non utilization of 100 % syrup
• Evaporation of spent wash to the RIGHT SOLIDS
• Working of Spent wash incinerator
• Quality of DDGS
• How to approach ZERO LIQUID DISCHARGE?
• Process Streams
• Non Process streams
• Steam & Power Balance
TECHNICAL:
• Right Project Investments
• Ideal Operating Costs
• Commercial Viability of expansions
FINANCIAL:
• Skill sets of Team
• Operational philosophy
• Right mix between Manual Operations Vs Automation
OPERATIONAL

Challenges…..
Grain Based Plants
• Further reduction in energy consumption
• Evaporation of entire quantity of thin slops without steam
• No recycle of Thin slops in the Liquefaction
• Maintaining higher solids in thick slops
• Use of 100% Syrup in Drying process
• Use of Dryer vapours for energy optimization
Molasses Based Plants
Effluent treatment:
• BSW / RSW / RO Reject Evaporation
• Reduction in steam & energy
• Recycle of waste streams
Investment:
• Which route : EPC/EPCM/ Turn Key Contract ?
• In house Project Management or out sourced ?
Confidential | Copyright © VAPCO Engineers Pvt. Ltd.
Two different types of Feed
Wet cake + Thick Slurry
Variation in feed specifications
• Inlet solids
• Different grains as feed to Distillery
• Stable unit operations (Decantation & Evaporation)
Large amount of mass
Higher Steam Consumption
Capability to handle Syrup
Higher product temperature
Higher Back Mixing
Maintaining Nutritional value of DDGS
Maintaining DDGS Color & Fragrance
Challenges in Drying @ DDGS

What does it mean…
Dryer for which material?
• Usage pattern of RM on yearly basis
• Influencing Grain
• Uniform mix of usage
• Heavy use of one type of Grain on yearly basis
• Selection Criteria:
• Technical Requirement
• Investment Vs Returns
• keep option of DWGS !!!
