Abstract: A system and a method for producing a marine fuel are provided. An exemplary method includes processing a crude oil stream to remove at least a portion of metal contaminants to form a demetallized oil, processing the demetallized oil to remove at least a portion of sulfur contaminants to form a desulfurized oil, and stabilizing the desulfurized oil by removing light hydrocarbons to form the marine fuel.

Abstract: A method to enhance flow rate data that includes receiving flow rate data that includes a plurality of data values from a device measuring a flow rate of a fluid in a pipeline. The method further includes identifying and correcting erroneous data values with a flow rate signal enhancement system configured to determine a plurality of delta values and to detect discontinuities in the flow rate data by comparing the plurality of delta values to a continuity threshold. The flow rate signal enhancement system is further configured to correct data values associated with detected discontinuities with an interpolation method and identify erroneous data values. The flow rate signal enhancement system is further configured to determine a condition of the pipeline associated with each identified erroneous data value, correct erroneous data values based on the condition of the pipeline, and compile enhanced (corrected) data flow rate data.

Abstract: A method of forming C6-C8 aromatics may include selectively dealkylating a Fluid Catalytic Cracking (FCC) heavy cut naphtha that has at least C9+ aromatics to selectively crack C2+ alkyl chains from the C9+ aromatics, thereby forming the C6-C8 aromatics. The selectively de-alkylated heavy cut naphtha is then combined with a FCC middle cut naphtha, and aromatics including the C6-C8 aromatics are separated from the combined stream. A system for forming C6-C8 aromatics may include a fluid catalytic cracking unit for producing a FCC heavy cut naphtha comprising at least C9+ aromatics; a de-alkylation reactor for selectively cracking C2+ alkyl chains from the C9+ aromatics, thereby forming the C6-C8 aromatics; and an aromatic extraction unit for extracting at least a portion of the C6-C8 aromatics.
