The Chief Ethanol Fuels facility is utilizing Vogelbusch-licensed technology. In 2007, a third molecular sieve drying system was designed and installed, raising operating capacity to 832,000 liters per day.

The cooperation first started in 1983 when Chief Ethanol Fuels set up af 120,000 liters per day plant. Vogelbusch process design included MultiCont© continuous fermentation, MultiPressure distillation, and azeotropic dehydration using cyclohexane as an entrainer. The dry milling process was designed to use corn (maize) and/or milo (grain sorghum) as feedstock. By-products include DDGS (distillers’ dried grains with solubles) and DWGS (distillers’ wet grains with solubles).

In 1993, Vogelbusch technology was again featured in the expansion of the facility to a capacity of 325,000 liters per day. Azeotropic dehydration was replaced with a PSA (pressure-swing adsorption), molecular sieve alcohol dryer that was fed directly with vapor from the rectifying column. In addition, 190 proof vapor off the top of the rectifying column was routed to the first effect of a two-stage stillage evaporator where it was condensed and returned to the rectifying column as reflux. This heat-saving design resulted in reducing thermal energy consumption by 25 %.

Five years later, plant capacity was more than doubled to 670,000 liters per day. In addition to providing technology, Vogelbusch also designed and supplied components for a second molecular sieve alcohol drying system.

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.
