Neutral Alcohol Plant in Ahwaz

The plant now operated by Razi (formerly Sugar Cane By-Products Corporation) was designed for a daily capacity of 110,000 liters of high quality pharmaceutical alcohol from cane molasses complying with EU standards. A special challenge was designing the plant for the extreme climatic conditions (0°C to 50°C) and the highest earthquake level UBC Zone 3.
The design and stress calculations in compliance with European standards for apparatus, tanks and pipelines were carried out at Vogelbusch and the assembly was performed in Iran under our supervision.
The following plant components were supplied: molasses reception and storage; continuous fermentation with untreated cane molasses including nutrient preparation and fermentation air supply; distillation with methanol separation and mash column under vacuum, (implemented as an energy saving MultiPressure system) alcohol storage and filling systems for trucks, rail tankers and barrels; central CIP system; cooling water unit; and laboratory. For those groups the complete piping material, the instrumentation and control as well as electrical components were supplied. Automation is based on a modern DCS system.
Following a four-year erection period and a short start-up phase in the first quarter of 2007, a test run was carried out, and the guaranteed product quality was achieved.
