... Abstract Mercaptans are naturally occurring components of sour crude oil and natural gas condensate. When present in appreciable concentrations, they generate a very disagrenable smell which can be a nuisance to operators and to surrounding communities. Regulatory authorities aften require...

... Abstract Removing mercaptans from sour natural gas has always been considered as a challenge. This is becoming an even more important issue with the global trend towards more stringent specifications for commercial gases. Amines have been extensively used because of their ability to meet...

...Introduction Abstract The formation of mercaptans and organosulfur species in Claus process leads to a reduction in the sulfur recovery efficiency, and an increase in the cost of tail gas treatment. While process optimization can be used to minimize their production in plants, the existing...

... Abstract Sulfur contaminants in the form of hydrogen sulfide and mercaptans are undesirable for various reasons during sour crude production. For example, hydrogen sulfide and mercaptans can be hazardous to personnel. Their presence can create major corrosion issues pertaining to the assets...

... Abstract Hydrogen sulfide and mercaptans are highly toxic. They can cause corrosion and contaminate fuels. For safe and efficient operation of oilfield applications, it is important to remove these constituents. Processes to remove sour gases with mercaptans include treatment of the hydrocarbon...

... At the end of the nineties, production of new fields has resulted in an increase of the mercaptans content in sour gases sent to upstream plants of the GASCO complex. As a consequence, the mercaptan content of the NGL stream was significantly increased and Ruwais plant molecular sieves units have...

... Abstract Mercaptans occur naturally in sour crude and condensate and cause an unpleasant odor which is a nuisance to operators and surrounding communities. Regulatory authorities often require control of mercaptan odors. A facility in Alberta stores condensate for use as a bitumen diluent...

... ABSTRACT Measured corrosion rates of carbon, low alloy, and stainless steels are significantly higher than that predicted by the modified McConomy curves in cases where significant concentrations of mercaptans are present in crude oils and hydrocarbon condensates. It suggested...

... Abstract. A major increase in mercaptan-containing crudes and gas condensates makes crude demercaptanization (DMC) an extremely important problem. The light crudes and gas condensates of Tengiz, Janajolsk, Markovsk, Douglas, and Qatar condensates have a high mercaptan content as well...

... Abstract Mercaptans are added to odorless natural gas for safety reasons. In normal operations, gas companies add mercaptans to natural gas when delivered to the city gates station for commercial usage. Gas transported in gas transmission lines and underground gas storage fields normally does...
