Abstract
Acrolein is a useful additive for treating hydrocarbon fluids, such as crude oil, for multiple purposes including, but not necessarily limited to, reducing or preventing microbial activity, scavenging hydrogen sulfide (H2S), and/or at least partially dissolving iron sulfide (FexSy). Acrolein can be stabilized against decomposition by mixing or combining it with at least one alkyl carbonate, which can also raise the flash point of the stabilized acrolein composition.
Claims18
A method for stabilizing acrolein from decomposition, the method comprising mixing:
- acrolein;
- and
- an amount of at least one alkyl carbonate solvent effective to stabilize the acrolein from decomposing;
- to form a stabilized acrolein composition.
A stabilized acrolein composition comprising:
- acrolein;
- and
- an amount of at least one alkyl carbonate solvent effective to stabilize the acrolein from decomposing.
A method for treating a hydrocarbon fluid, the method comprising:
- introducing an amount of a stabilized acrolein composition into the hydrocarbon fluid in an amount effective for treating it,
- where the stabilized acrolein composition comprises:
- acrolein;
- and
- an amount of at least one alkyl carbonate solvent effective to stabilize the acrolein from decomposing within the stabilized acrolein composition.
