Ether Product

The boiling point of the ETBE product depends strongly on its purity from below ambient temperature where excess hydrocarbon is included in the bottoms to 70°C at an ETBE purity of 96%. Pressurised storage is not required provided the product can be cooled satisfactorily from the column operating temperature. A 205 L drum is used to collect the product. A cap on top of the drum prevents excessive loss of flammable vapour through evaporation. Sub-optimal operation will result in a much larger than normal concentration of ethanol in the ether product. However, the boiling point of ethanol is also safely above ambient temperatures. If necessary, the bottoms product can be recycled to either feed tank if atmospheric collection is not appropriate.
