Abstract
A method for reducing the amount of hydrogen sulfide present in liquid hydrocarbon media while minimizing the amount of corrosion in processing equipment contacting the liquid hydrocarbon media. The method includes adjusting a glyoxal solution to a pH of from about 2.5 to about 6.0 and dispersing the adjusted glyoxal solution in the liquid hydrocarbon media. A hydrogen sulfide scavenging composition and method for making are also provided.
Claims32
A method for reducing the amount of hydrogen sulfide present in a liquid hydrocarbon media while minimizing the amount of corrosion in processing equipment contacting the liquid hydrocarbon media, said method comprising adjusting a pH value of a glyoxal solution to a pH in a range of from about 2.5 to about 6.0 and dispersing the adjusted glyoxal solution in the liquid hydrocarbon media.
A hydrogen sulfide scavenging composition comprising a glyoxal solution and a neutralizing agent and having a pH in the range of from about 2,5 to about 6.0.
A process for making a hydrogen sulfide scavenging composition comprising adjusting a glyoxal solution with neutralizing agents to a pH in a range of from about 2.5 to about 6.0.
A method for reducing the amount of hydrogen sulfide present in a liquid hydrocarbon media contained in a land-or boat holding tank, while minimizing the amount of corrosion of the holding tank, the method comprising adding a glyoxal solution to the liquid hydrocarbon media, forming an aqueous solution containing acidic components from the glyoxal solution inside the holding tank, and adjusting the pH of the aqueous solution to a range of from 4 to 11, wherein the aqueous solution forms a phase in contact with the hydrocarbon media and the holding tank's inner surface, and wherein the phase is continuous or semi-continuous.
