Mercaptan sulfur in crude oil

Mercaptan sulphur is generally present in crude petroleum in the form of methyl mercaptan, which is produced during the microorganic decomposition of animal and vegetable matter.

In a mercaptan oxidation (Merox) unit, these mercaptans are removed from the crude oil in a two-step process.

Several of these compounds are also found in crude petroleum oil. The industrial manufacture of mercaptans is carried out by combining an alcohol with hydrogen sulfide (H 2 S), for example, methyl mercaptan is produced by the reaction CH 3 OH + H 2 S -> CH 3 SH + H 2 O. The Zhanazol crude oil contains approximately 659ppm/wt of C1–C5 mercaptan measured as sulphur. There are other heavier mercaptans in the crude oil but fortunately the lighter (lower molecular weight) C1–C3 mercaptan species, which represent 469ppm of the total, are the most odorous and thus the ones targeted for removal. T ypical range of variation: 0.002 - 4 wt% total sulfur in crude oil. Back to Content Boiling and melting points, density, structure and molweight of organic sulfur compounds. Trace metal. What: Determination of nickel, vanadium, iron, sodium and other trace metals in crude oils and residual fuels . Why: Several of these compounds are also found in crude petroleum oil. The industrial manufacture of mercaptans is carried out by combining an alcohol with hydrogen sulfide (H 2 S), for example, methyl mercaptan is produced by the reaction CH 3 OH + H 2 S -> CH 3 SH + H 2 O. Petroleum refining - Petroleum refining - Mercaptan extraction: Simple sweetening is adequate for many purposes, but other methods must be used if the total sulfur content of the fuel is to be reduced. When solutizers, such as potassium isobutyrate and sodium cresylate, are added to caustic soda, the solubility of the higher mercaptans is increased and they can be extracted from the oil. In The corrosivity of four mercaptans and selected crude oil fractions were measured in lab tests. Conclusion: Mercaptan corrosion can contribute significantly to the total sulfur related corrosion in the temperature range 235–300°C, which agrees with observations of elevated temperature corrosion in refinery distillation equipment.

(17,500 m3) holding tank, typically contains 150 to 400 ppm of total mercaptans (as sulfur). Crude oil or condensate products often contain naturally occurring mercaptans. Excessive corrosivity of several crude oils and condensates with high mercaptan concentrations has been observed in distillation units. Published corrosion  3 Apr 2019 Mercaptan sulphur is generally present in crude petroleum in the form of methyl mercaptan, which is produced during the microorganic
