Abstract: Methods for the prevention or mitigation of fouling in amine-treating systems comprising providing circulating aqueous amine solution and a hydrocarbon stream comprising at least one acid gas; and interacting the circulating aqueous amine solution with the hydrocarbon stream comprising the at least one acid gas to remove the acid gas from the hydrocarbon stream and entrain the acid gas into the aqueous amine solution. The circulating aqueous amine solution comprises entrained acid gas comprises foulant precursors; and polysulfide ions are introduced to react with the foulant precursors to decrease the rate of fouling within the circulating aqueous amine solution.

Abstract: Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any “pitch” generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.

Abstract: A low-cost process for cleansing a liquid of volatile contaminants can be accomplished by cross flowing a liquid through a contactor vessel. As the liquid to be cleansed of contaminates cross flows through the horizontal contactor vessel, a radial flow pattern is induced in the liquid and the liquid is contacted with a cleansing gas introduced cross current to the flow of the liquid through the contactor vessel. As the liquid moves through the contactor vessel, contaminants enter the cleansing cross current gas percolating through the liquid. The cross current gas may then be collected and cleansed of the contaminates it collected. The cleaned cleansing gas may then be recycled back into the contactor vessel. The liquid to be cleansed may by any liquid or liquefied hydrocarbon, such as liquefied petroleum gas, gasoline, diesel, refinery component streams, distillates, gas oils, crude oils and/or emulsions. The volatile contaminates that may be cleansed from liquid include any undesirable element within the cross flowing liquid that can be absorbed and/or dissolved in the cleansing cross current gas percolated through the liquid. The cross flowing liquid may be cleansed to varying degrees, depending on specific down streams requirements.
