低热值气体储备和技术解决方案货币化，通过带集成氮气回收的脱氮、NGL 萃取、LNG 和/或 LIN 生产实现收益最大化。
Cryogenic NRU offers the highest methane recovery rates and is standard practice for plants >15 MMSCFD.A Chart integrated nitrogen rejection unit is the ideal solution for the monetization of low btu gas reserves and increased revenue opportunities through the recovery of natural gas liquids (NGL) and helium and the off-take of LNG and liquid nitrogen.
Single low pressure column NRU
Single high pressure column NRU
Two (or more) Column NRU
Where inlet nitrogen concentrations are <40% and/or integrated helium recovery is required Chart’s patented and proven pre-fractionator nitrogen rejection technology is the optimum processing solution.The resultant two column design features a pre-fractionator followed by a low pressure NRU fractionator and offers the following:
