This article describes the adsorption capability of natural zeolites for the purification and dehydration of natural gases. Studies were carried out with natural clinoptilolite treated with various cadmium and titanium solutions. Zeolite-containing…
The determination of water content in crude oil is important for oil transportation, refining, and trade. However, the sensitivity and accuracy of the conventional azeotropic distillation (AD) method are inadequate. Karl Fischer titration methods may…
Scope: This test method covers the determination of the boiling range distribution of petroleum products. The test method is applicable to petroleum products and fractions having a final boiling point of 538C (1000F) or lower at atmospheric pressure…
1 Scope This document specifies a test method for the determination of the content of mono-aromatic, di-aromatic and tri+-aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates. This document defines two procedures,…
Sulfur compounds have significant geochemical information, and the removal of sulfur from petroleum products is one of the most important tasks in petroleum refining. However, it is a challenging task to reveal the chemical composition of sulfide at…
Detailed molecular analysis of complex mixtures such as crude oil and its fractions has been successfully covered by a number of groups during the past two decades. On the other side, the most glaring need is some type of method that allows…
Scope: This document specifies a method for the determination of hydrogen sulfide content in working field natural gas of upstream area by laser absorption spectroscopy. The analytical range expressed as mole fraction is 10 10-6 to 20 %. The…
This study reports a comprehensive approach for analysis of increasing hydrogen sulfide (H2S) concentration after 10 years of sweet gas production from Kangan and Dalan formations (Khuff) in a gas field. Increasing H2S concentration as a toxic and…
This paper discusses metrologically the best practice regarding the calibration curves applied to H2S mass fractions determination in natural gas by gas chromatography with sulfur chemiluminescence detection (GC-SCD). Three calibration curves were…
A new method was proposed for hydrogen sulfide removal from natural gas through the utilization of supersonic flow in a Laval nozzle. For this purpose, a mathematical model was established for the supersonic non-equilibrium condensation flow of the…
Hydrogen sulfide (H2S) is an undesirable compound in oil and gas reservoirs, which reduces the economic value of gas reservoirs and has toxic and corrosive effects on reservoir operation equipment. Albeit initial generation mechanisms of hydrogen…
Crude oils produced from different reservoirs in the world have very different chemical compositions and physicochemical properties. Naphthenic acids and sulphur content can affect the properties and impact the processing and refining of oils.…
Kashagan oil field has been under production since September 2016. The produced oil is associated with considerable amounts of sour gas that must be processed or disposed of while minimizing flaring. This paper will focus on the methodology for field…
This article describes the adsorption capability of natural zeolites for the purification and dehydration of natural gases. Studies were carried out with natural clinoptilolite treated with various cadmium and titanium solutions. Zeolite-containing…
As a complex mixture, high-hydrogen-sulfide natural gas has a high risk of poisoning and explosions after leakage. This study combined wind tunnel experiments, computational fluid dynamics (CFD) technology, and risk theory to explore the dispersion…
