Abstract

Monoethylene Glycol is a widely used chemical and is a crucial component in the manufacturing of polyester film and fibers, Polyethylene Terephthalate (PET) resins and engine coolants. Monoethylene glycol application ranging from clothing and textiles, kitchenware, engine coolants, antifreeze, and packaging. In 2011, the global usage and production of monoethylene glycol
reach 20 million metric tons and is expected to increase 5-10% each year. However, conventionally the production of Monoethylene Glycol is not considered as a sustainable process since it is known as an energy intensive process. Production of Monoethylene Glycol usually involves excess water and the ratio of water to ethylene oxide is 20:1. Besides that the conversion of this process also did not reach maximum conversion. By applying reactive distillation column to replace the conventional process the problems stated above can be solved. Analysis for the selectivity, conversion, process mass intensity, heat and pressure will result in higher selectivity toward product, maximum conversion, lesser capital investment and lower energy usage. The simulation and modelling for this process will be carried out in ASPEN Plus TM. The result from this simulation is by using lesser molar ratio of water and ethylene oxide the conversion is bigger than 99% and the process mass intensity of reactive distillation column is 1, where all the raw material is converted to monoethylene glycol.
