Analyzing hazards of sour water spills
Process Safety Progress, 2007AbstractThis article illustrates evaluating the consequence of a large spill of sour water by modeling the plume of hydrogen sulfide and ammonia to toxic limits. This modeling uses chemical equilibrium constants and rigorous thermodynamic formulas, coupled with dispersion modeling to show how the plume contours of H2S and of NH3 vary with initial ...

A New Inhibitor for Corrosion In Aerated Sour Waters
SPE Symposium on Handling of Oilfield Water, 1972Abstract Aggravated corrosion conditions caused by FeS sol ids and by mixed air plus H2S interactions are responsible for some of the highest equipment failure rates in the petroleum industry. laboratory studies have shown the existence of a transient, ionic, sulfur species which is formed when air and H2S react in ...

CORROSION 2002, 2002
Abstract The performance of three aluminium anode materials has been evaluated for a sub-sea gas transmission line with an external sour environment. Anode capacity tests were carried out in simulated service environments containing sour sea water with 10 ppm H2S and 2000 ppm H2S and sour sediment with 1000 ppm H2S.

Warming Waters and Souring Seas
2016Abstract This chapter examines the impact of climate change and ocean acidification on the oceans and their implications for the international law of the sea. In particular, it assesses the implications of rising sea levels for territorial sea baselines, the seawards extent of maritime zones, and maritime boundaries.

Sour water–gas shift reaction over Pt/CeZrO2 catalysts
Journal of Catalysis, 2016The influence of H2S on the performance of platinum catalysts for the water–gas shift reaction was investigated. Platinum catalysts supported on different oxides (γ-Al2O3, ZrO2, CeO2, Ce0.75Zr0.25O2, and Ce0.25Zr0.75O2) were tested under industrial conditions in the absence and presence of H2S.

Estimation of the Water Content of Sour Natural Gases
Society of Petroleum Engineers Journal, 1977Abstract Equilibrium water contents of sour natural gases are predicted using the Soave modification of the Redlich-Kwong equation of state. Calculated results are compared with published experimental data and with 180 field observations that were collected from the natural gas industry of western Canada and France.

Corrosion Behavior of UNS N08935 in Refinery Sour Water Services
CORROSION 2021, 2021Abstract The nature of hydroprocessing reactor effluent air coolers (REAC’s) to form hydrogen sulfide (H2S) and ammonia (NH3) from sulfur and nitrogen species present in the feed makes them prone to ammonium bisulfide (NH4HS) corrosion. Various industry driven research have helped understand the relationship between the hydrogen sulfide ...

Sour water–gas shift reaction over Pt/CeO2 catalysts
Catalysis Today, 2011Abstract Ceria-supported catalysts with 0.38–2.0 wt.% Pt have been studied under high-temperature water–gas shift (WGS) conditions with and without 20 ppm H 2 S present, which is a typical level in feed streams for WGS reactors in IGCC power plants. The effect of H 2 S on CO conversion decreased with increasing temperature in the range 573–723 K and ...

Prediction of water content of sour and acid gases
Fluid Phase Equilibria, 2010Abstract Estimating the feasibility of acid gas geological disposal requires the knowledge of the water content of the gas phase at moderate pressures and temperatures (typically below 50 MPa, below 380 K) and up to 6 mol NaCl. In this paper, a non-iterative model is developed to predict the water content of sour and acid gases at equilibrium with ...
