Abstract
Methods and a system for manufacturing a base stock from an ethanol stream are provided. An example method includes dehydrating an ethanol stream to form an impure ethylene stream, recovering an ethylene stream from the impure ethylene stream, and oligomerizing the ethylene stream to form a raw oligomer stream. A light olefinic stream is distilled from the raw oligomer stream and blended with the ethylene stream prior to the oligomerization. A heavy olefinic stream is distilled from the raw oligomer stream and hydro-processed to form a hydro-processed stream. The hydro-processed stream is distilled to form the base stock.
