The ancillary process for methanol production is purification. The aim of purification process is to separate the methanol from any impurities such as water, alcohol, alkanes, etc. Methanol is transferred to storage tanks which is specially assigned for crude Methanol. The Methanol will then be feed to the next part of the operation which is purification. In two different distillation columns, Methanol is purify to achieve the product quality which is required. In the first column, low boiling impurities known as light ends are removed. Light ends are materials that have a lower boiling point than Methanol. When heated, these materials will boil before Methanol. These unwanted impurities can be seperated out from the top of the column by
