SCAVENGING SYSTEM

摘要

A vessel emptying system for emptying CNGs from a vessel used to transport CNG, the vessel being one of a plurality of cylindrical containers that are arranged vertically, with substantially parallel axes, wherein said system is arranged to expand the CNG through a turboexpander-compressor device (40, 50), the turboexpander-compressor device (40, 50) being adapted to use kinetic energy from the resulting rotation or movement of that turboexpander-compressor device (40, 50) in a secondary gas processing step of the system. publication
