The refining of crude methanol into high purity product methanol is an energy intensive process and a key unit operation in industrial methanol production.  In methanol refining a multi-component feed of methanol, water and trace amounts of ethanol, butanol and higher alcohols are refined to achieve a high purity product (Pure methanol with <10 ppm of ethanol inclusions ) and bottoms (pure water with > 5 ppm of other inclusions).  To achieve this high purity requirements, these refining columns have a side draw where ethanol, butanol as well as other higher alcohols are removed. In the recent years, due to ever stringent environmental constraints and commercial requirements these columns are required to operate at increased product methanol recoveries of ≥ 97.5 %.  This push to increase methanol recovery results in the composition of side draw which in current operations is a mixture of methanol and water to change to a predominantly water. As a result butanol and other higher order alcohols which are non-polar in nature will be repelled from the side draw region potentially resulting in the formation of a secondary phase, which in turn leads to a loss of process efficiency. 

In this project you will be tackling this problem from both a theoretical and an experimental angle where you will be looking into the thermodynamics of Methanol/Water mixtures with trace amounts of Butanol and higher order alcohols. This information will then be combined with state-of-the-art process simulations to determine the practical operations envelop of product recoveries that can obtained in an industry standard side draw column configuration. The study can be also extended further to look into other column design configurations currently being developed in industry subject ECTS requirements.
