RAFFINATE

Raffinate is primarily a mixture of the butylenes and butane components such as, isobutane and n-butane. Raffinate is a colorless gas (liquid under pressure) with a mild petroleum odor. Raffinate 1 is the hydrocarbons remaining after extraction of butadiene. Raffinate 1 is a combination of- butenes with butane. Raffinate 2 is the hydrocarbons remaining after extraction of isobutylene. It consists of n-butenes and n-butane. Raffinate 3 is the C4 hydrocarbons remaining after butane-1 is removed; primarily butane-2 and butanes.

Product Uses

Raffinate 1 is a chemical building block used in the manufacture of methyl tertiary butyl ether (MTBE). Raffinate 2 is used in the manufacture of secondary butyl alcohol (SBA) and methyl ethyl ketone (MEK). Raffinate 3 is primarily used as feedstock in the production of gasoline
