Abstract
Provided here are methods and systems for treatment of a hydrocarbon feedstock fluid during transportation to reduce contaminants harmful to refinery cracking units. Methods include transporting a contaminated hydrocarbon feedstock fluid in a transport container outfitted with removable units containing an adsorbent. The removable units can be exchanged to provide fresh adsorbent, or configured to treat specific contaminants present in the hydrocarbon feedstock fluid.
Claims20
A method of pretreating a hydrocarbon feedstock fluid in a transport container, the method comprising:
- supplying a hydrocarbon feedstock fluid containing at least one contaminant to a transport container configured to transport the hydrocarbon feedstock fluid in bulk to a hydrocarbon processing facility, the at least one contaminant being one or more of diolefin compounds, oxygen compounds, nitrogen compounds, or halogen compounds;
- contacting the hydrocarbon feedstock fluid with an adsorbent contained within a removable unit positioned inside the transport container, the removable unit being configured to provide fluid communication between the hydrocarbon feedstock fluid and the adsorbent;
- and
- causing deposition of a portion of the at least one contaminant from the hydrocarbon feedstock fluid onto the adsorbent to produce a pretreated hydrocarbon feedstock fluid containing a reduced amount of the at least one contaminant.
A method of pretreating a hydrocarbon feedstock fluid in a transport container, the method comprising:
- supplying a hydrocarbon feedstock fluid containing two or more contaminants to a transport container configured to transport the hydrocarbon feedstock fluid in bulk to a hydrocarbon processing facility, the two or more contaminants being diolefin compounds, oxygen compounds, nitrogen compounds, halogen compounds, or combinations thereof;
- contacting the hydrocarbon feedstock fluid with a first adsorbent contained within a first removable unit positioned inside the transport container, the first removable unit being configured to provide fluid communication between the hydrocarbon feedstock fluid and the first adsorbent;
- contacting the hydrocarbon feedstock fluid with a second adsorbent contained within a second removable unit positioned inside the transport container, the second removable unit being configured to provide fluid communication between the hydrocarbon feedstock fluid and the second adsorbent;
- and
- causing deposition of a portion of a first contaminant from the hydrocarbon feedstock fluid onto the first adsorbent and deposition of a portion of a second contaminant from the hydrocarbon feedstock fluid onto the second adsorbent to produce a pretreated hydrocarbon feedstock fluid containing reduced amounts of the first contaminant and the second contaminant.
A method of pretreating a hydrocarbon feedstock fluid in a transport container, the method comprising:
- supplying a hydrocarbon feedstock fluid containing at least one contaminant to a transport container configured to transport the hydrocarbon feedstock fluid in bulk to a hydrocarbon processing facility, the at least one contaminant being one or more of diolefin compounds, oxygen compounds, nitrogen compounds, or halogen compounds;
- contacting the hydrocarbon feedstock fluid with an adsorbent present as a fixed bed within a circulation system positioned inside the transport container, the circulation system equipped with a pump to circulate the hydrocarbon feedstock fluid through the fixed bed of the adsorbent;
- and
- causing deposition of a portion of the at least one contaminant from the hydrocarbon feedstock fluid onto the adsorbent to produce a pretreated hydrocarbon feedstock fluid containing a reduced amount of the at least one contaminant.
