Optimize sulfur recovery: Sub-dewpoint sulfur recovery with interstage membrane
The author’s company’s new sub-dewpoint sulfur recovery with interstage membrane (SSRIM) technology is a breakthrough for the sulfur recovery industry, as it is the first technology capable of achieving an overall recovery efficiency of > 99.9% without requiring a tail gas treating unit. This article discusses the basic SSRIM configuration and its advantages when compared to a traditional Claus/TGT configuration.
SOCAR, Baker Hughes partner on integrated gas recovery, H2S removal system at the Heydar Oil Refinery
Baker Hughes and SOCAR signed a contract for an integrated gas recovery and hydrogen sulfide (H2S) removal system that will significantly reduce downstream flaring at SOCAR’s Heydar Aliyev Oil Refinery in Baku, Azerbaijan.
Stamicarbon awarded a PDP contract for Mexican nitric acid plant
Stamicarbon will apply its proprietary NX Stami Nitrates technology for a tailor-made solution to remove nitrous oxide from the tail gas stream, optimizing nitric acid production and reducing the carbon footprint of the plant
Why sulfur plants fail: An in-depth study of sulfur recovery unit failures—Part 2
Equipment malfunction or an unplanned shutdown of a sulfur recovery unit (SRU) can have a significant effect on a production company’s profitability, along with an equally serious impact on personnel safety and the environment.
Soft startup of best practices for the commissioning of amine plants
The startup and commissioning of hydrocarbon plants can present unique challenges that, if not anticipated and addressed in the pre-commissioning and commissioning periods, will inhibit plant startup and increase the difficulty of achieving product specifications in a timely manner.
