Abstract
A method of equipment decontamination may include: introducing a cleaning stream comprising hydrogen and a solvent comprising a fatty acid methyl ester and an oxygenated solvent, or alternatively—comprising a—carrier fluid and a hydro-carbon solvent, into the equipment; and introducing a stream comprising nitrogen into the equipment, wherein the equipment comprises deposits and other contaminants.
Claims20
A system, comprising:
- a component of fouled equipment comprising deposits;
- a hydrogen source;
- a solvent source, wherein the solvent comprises a hydrocarbon solvent and a cutting fluid;
- a nitrogen source;
- and
- one or more fluid connections configured to convey a cleaning stream comprising the hydrogen and vaporous solvent into the component of equipment and configured to convey nitrogen into the component of equipment subsequent to introduction of the cleaning stream into the component of equipment.
3 more elements
A system, comprising:
- a reactor comprising a catalyst, deposits on the catalyst, and other contaminants comprised of, but not limited to, hydrogen sulfide, benzene, LELs, or combinations thereof;
- a stream comprising hydrogen;
- a stream comprising a solvent comprising a hydrocarbon solvent and a cutting fluid;
- a cleaning stream comprising the solvent from the solvent stream vaporized and/or dispersed within the hydrogen from the hydrogen stream, wherein at least a portion of the cleaning stream is disposed within the reactor such that the cleaning stream is in contact with the deposits;
- and
- a nitrogen stream, wherein the nitrogen stream is configured to be introduced into the reactor subsequent to the cleaning stream.
