REMOVAL OF HYDROGEN SULPHIDE

Hydrogen sulphide is scavenged from a feedstock comprising crude oil and hydrogen sulphide by adding a compound of general formula: to the feedstock. X and Y are carbon or nitrogen atoms and the interatomic bond is triple or double as appropriate. Any two or more of R1-R4 are organic groups containi...

Beschreibung
Zusammenfassung:	Hydrogen sulphide is scavenged from a feedstock comprising crude oil and hydrogen sulphide by adding a compound of general formula: to the feedstock. X and Y are carbon or nitrogen atoms and the interatomic bond is triple or double as appropriate. Any two or more of R1-R4 are organic groups containing electronegative functional groups. The remaining two or less of R1-R4 are hydrocarbyl groups, hydrogen atoms or zero. Preferred scavengers include di-isopropylazo dicarboxylate and dimethylacetylene dicarboxylate.
