Title:
CONVEYING SYSTEM FOR OIL OR GAS
Document Type and Number:
WIPO Patent Application WO/2012/119703
Kind Code:
A3
Abstract:
The invention relates to a conveying system for oil or gas, comprising a drive unit generating an exhaust gas flow; a conveying system powered by the drive unit, in the form of a pump or a compressor, which conveys and/or compresses the oil or gas; and an exhaust gas energy recovery device, which converts the heat of the exhaust gas flow into mechanical energy. The invention is characterized in that the exhaust gas energy recovery device is provided with an operating medium circuit, the operating medium being water, a water mixture, ethanol, an ethanol mixture, ammonia or an ammonia mixture. The operating medium circuit is provided with a heat exchanger for transferring the heat of the exhaust gas flow to the operating medium in order to evaporate it, in part or completely, an expansion machine, in which the operating medium expands while doing mechanical work, and a condenser for condensing the operating medium. The invention is further characterized in that the expansion machine is mechanically coupled to the drive unit and/or to the conveying system and/or to an additional working unit in order to power same.
