Abstract
Sulfhydryl compounds, including hydrogen sulfide and mercaptans, may be removed from a fluid or gaseous stream or substrate by reacting the hydrogen sulfide and mercaptans in the stream with a scavenger of the structural formula: wherein R1, R2 and R3 are each independently selected from the group consisting of R4 and R5, R4 is a C1-C20 straight or branched chain alkyl group, R5 is —[(CH)m—NH]p—(CH2)nOH, n and m are independently an integer from 2 to about 6, p is from 1 to about 6; and wherein at least one of R1, R2 and R3 is R4 and at least one of R1, R2 and R3 is R5.
Claims20
A method for scavenging hydrogen sulfide and/or mercaptans from a liquid or gaseous stream which comprises bringing the stream into contact with a scavenging effective amount of at least one triazine of the formula:
- wherein R1, R2 and R3 are each independently selected from the group consisting of R4 and R5, R4 is a C1-C20 straight or branched chain alkyl group, R5 is —[(CH)m—NH]p—(CH2)nOH, n and m are independently an integer from 2 to about 6, p is from 1 to about 6;
- and
- further wherein at least one of R1, R2 and R3 is R4 and at least one of R1, R2 and R3 is R5.
A method for reducing an amount of sulfhydryl compounds in a hydrocarbon substrate, comprising mixing the hydrocarbon substrate with a scavenging effective amount of a triazine of the formula:
- wherein R1, R2 and R3 are each independently selected from the group consisting of R4 and R5, R4 is a C1-C20 straight or branched chain alkyl group, R5 is —[(CH)m—NH]p—(CH2)nOH, n and m are independently an integer from 2 to about 6, p is from 1 to about 6;
- and
- further wherein at least one of R1, R2 and R3 is R4 and at least one of R1, R2 and R3 is R5.
