Abstract
Systems and a method for manufacturing a base stock from a light gas stream are provided. An example method includes oxidizing the light gas stream to form a raw ethylene stream. Water is removed from the raw ethylene stream, and carbon monoxide in the raw ethylene stream is oxidized. Carbon dioxide is separated from the raw ethylene stream, and the raw ethylene stream is oligomerized to form a raw oligomer stream. A light olefinic stream is distilled from the raw oligomer stream and a light alpha olefin is recovered from the light olefinic stream. A heavy olefinic stream is distilled from the raw oligomer stream. The heavy olefinic stream is hydro-processed to form a hydro-processed stream. the hydro-processed stream is distilled to form the base stock.
