H2S/sour gas

A corrosive gas that is fatal to humans in high concentrations should not be a toxic substance under Canadian environmental law, say federal researchers in a new proposal.

A look at the challenges in creating a foamer with corrosion and scale inhibition properties for application in wet-gas production.

In this work, the potential of a new low-temperature distillation process for natural-gas sweetening has been investigated.

An Excel-based tool was developed that uses cubic-equation-of-state (EOS) and thermodynamic electrolyte-chemistry modeling to assess sour-production streams.

This paper focuses on a numerical-modeling analysis of the acid-gas-injection (AGI) scenario in carbonate HP/HT reservoirs, and presents the way in which AGI impacts asphaltene-precipitation behavior.

When panels in an instrument equipment shelter kept tripping and the occasional smell of H2S led to an investigation of the rationale. Although a rare occurrence, this paper presents a strategy for prevention through careful site selection.

The Pugang gas field, one of the biggest inland gas discoveries of the last decade in China, has hydrogen sulfide (H2S) concentrations as high as 10%, making surface- and downhole-facilities design and execution challenging.

Sour gas is being produced from a number of carbon-steel-completed wells in the US, Canada, France, and Saudi Arabia.

A large mature onshore Saudi Arabian oil field is producing sour crude oil that multiplies well-integrity challenges.

High H2S and CO2 content in natural gas pose significant challenges to processing equipment. This article explores the challenges of sulfur removal and high pressures in the presence of acid gas.
