Impacts of CO2 and H2S on the risk of hydrate formation during pipeline transport of natural gas

Solomon A. Aromada, Bjørn Kvamme

Frontiers of Chemical Science and Engineering 2019, Volume 13, Issue 3,   Pages 616-627 doi: 10.1007/s11705-019-1795-2

Abstract: The impacts of CO and H S in natural gas on the maximum mole-fractions of water that can be toleratedWater tolerance decreases with increase in concentration of H S.The maximum mole-fraction of water permitted in the gas to ensure prevention of hydrate formation alsodecreases with increase in the concentration of C H like H S.H S has the most impact, it tolerates the least amount of water among the components studied.

Internal corrosion control and monitoring of Puguang gas gathering system

Ou Li,Li Shijie,Su Guofeng

Strategic Study of CAE 2010, Volume 12, Issue 10,   Pages 70-75

Abstract:

The corrosion features of highly hydrogen sulfur and carbon dioxide sour gas field were introduced, and the corrosion research results of simulating site operation condition of Puguang gas gathering system during the Puguang Gas Field development were discussed. The corrosion control plan of"carbon steel + corrosion inhibitor + pigging + corrosion monitoring"  was expounded which is designed for the Puguang Gas Field with highly hydrogen sulfuer , involuted terrain, a dense population, and a "wet"  gas gathering system. The execution effect of corrosion control & monitoring was preliminarily evaluated, and the proposal for some existing problems was given.

Photoelectrocatalytic generation of H and S from toxic HS by using a novel BiOI/WO nanoflake array photoanode

Frontiers in Energy 2021, Volume 15, Issue 3,   Pages 744-751 doi: 10.1007/s11708-021-0775-7

Abstract: In this paper, a photoelectrocatalytic (PEC) recovery of toxic H2S into H2 andsub>2S totally converted S2– into S without any polysulfide (H2 was simultaneously generated at a rate of about 0.867 mL/(h·cm).The proposed PEC H2S splitting system provides an efficient and sustainable route to recoverH2 and S.
