摘要: This invention is directed to a method of removing dimethyl ether from an olefin stream. The method includes distilling the olefin stream so that the dimethyl ether is separated out of the olefin stream with propane. The olefin stream can then be further distilled to provide a polymer grade ethylene stream and a polymer grade propylene stream, with each stream containing not greater than about 10 wppm dimethyl ether.

摘要: A composite sheet material that includes at least one porous core layer including a thermoplastic material and from about 20 weight percent to about 80 weight percent fibers based on a total weight of the porous core layer, and at least one skin covering a surface of the core layer. The skin includes at least one of a thermoplastic film, a fiber based scrim, a non-woven fabric, and a woven fabric.

摘要: Disclosed is a system of making an olefin derivative from a dilute olefin feed. Dilute olefin is sent to an olefin reaction unit to form an olefin derivative product. The olefin derivative product is recovered from the reaction unit while a vent stream is also removed. Olefin is separated from the vent stream, and the olefin is sent to the olefin reaction unit for additional processing.
