100 klpd 2g ethanol plant at iocl panipat

India’s first 2G Ethanol Plant has been constructed by Indian Oil Corporation Limited (IOCL) at an estimated cost of around Rs 900 crore and is located close to Panipat Refinery, with capacity of producing 100 KL of Ethanol per day using rice straw as feedstock

Ethanol from rice straw as feedstock

The utilization of lignocellulosic biomass for bioethanol production necessitates the production technology to be cost-effective and environmentally sustainable. Considering the evolution and need of second-generation biofuels, rice straw appears a promising and potent candidate for production of bioethanol due to its abundant availability and attractive composition. Biological conversion of rice straw into fermentable sugars, employing hydrolyzing enzymes is at present the most attractive

Challenge

• Use of SPI (smart plant instrumentation) for Instruments datasheet.
•  Use of PDMS for 3D Model.
•  Use of E plan for engineering drawing.
• Preparation of P&ID, PFD etc.
•  Preparation of cable tray layout & lightning & earthing layout.

Overview of Biomass size reduction Mill

Solution

Application Details - Biomass Reduction System Design Parameters

• Design Capacity: 7.5 TPH paddy straw / per train on Wet basis inclusive of moisture of 15%w/w
• Output Capacity: 5.7 TPH shredded Paddy Straw / per train (based on moisture of 20 %w/w)

Output

• 10 mm - 30mm:>=90%
• Between 30 mm -40 mm :<=5%
• Between 30 mm -40 mm :<=4.8%
•  Above 50 mm :<=0.2%

The System is designed for processing 30 TPH of Paddy Straw on 24 hours/day operation, with 5 trains in operation, with adequate redundancy for trouble free continuous operation. Briefly, our scope consists of the supply of 6 (5 +1) trains with the following equipment in each train.

• Bale Disintegrator
• Feed Conveyor
• Biomass Size Reduction Mill
• Cyclone Separator
• Bag Filters
• Compressor
• Induced Draft Fan
