A continuous purification system overcomes amine degradation and the formation of corrosion-promoting heat stable amine salts.
Sulige Gasfield is located mainly in Erdos, Inner Mongolia Autonomous Region and Dingbian County, Shanxi Province. It is a strategic succeeding area of natural gas for Changqing Oil Field Company, PetroChina. There are 5 gas processing plants. The first plant has an annual natural gas processing capacity of 3 billion cubic meters and the others 5 billion. The sixth plant is under construction and to be operational by the end of 2013, resulting in a total capacity of gathering and transferring, and processing will reach 28 billion in Sulige once it is put into production.
Advances in gas treatment technologies over the past 10 to 20 yeasrs have widened the range of economically recoverable gas sources.
A hydrogenation catalyst capable of operating at low temperatured can substantially improve the performance of the tail gas treatment process. Possible configurations and achievements of the treatment using this catalyst are presented.
RAR Multipurpose, a variant of the RAR process, combines acid gas enrichment and Claus tail gas treatment, allowing the safe and efficient treatment of very lean H2S feedstocks containing impurities that can not be tolerated in Claus units. The paper describes the peculiar features, performances and experience in industrial plants, as well as the limits of application of the technology in the treatment of the lean feed streams.
With the old trays in the scrap yard and no working drawings available, an amine still revamp called for engineering detective work.
