    Abstract: Described herein are systems and methods of fouling mitigation in a hydrocarbon fractionation column. The methods correlate operating parameters of the fractionation column, specifically flow rate and temperature, with fouling. The methods can include measuring a temperature and a flow rate at a bottom stream of the hydrocarbon fractionation column; providing the measured temperature and flow rate to a processing device; determining, by the processing device, based on the measured temperature and flow rate of the bottom stream, an antifoulant treatment protocol for the hydrocarbon fractionation column; and treating the hydrocarbon fractionation column by controlling, by the processing device, a feed control unit in accordance with the determined antifoulant treatment protocol.

    Abstract: Processes and systems that control operation of a commercial refinery distillation column and/or splitter operable to separate hydrocarbons. An automated process controller (APC) receives signal from at least one analyzer that provides information about the concentration of at least a first chemical in a first fraction and a second chemical in a second fraction obtained from the distillation column. The APC comprises programming in the form of an algorithm that calculates real-time monetary values for the first chemical and the second chemical and alters the operation of the distillation column to change either the percentage of the first chemical in the second fraction or the percentage of the second chemical in the first fraction, thereby maximizing overall operational profit for the distillation column.

    Abstract: The process can include transferring heat from a light product in a first heat exchange stage to produce a cooled product and a first medium pressure steam and separating a steam cracker quench oil therefrom. Heat can be transferred from the steam cracker quench oil in a second heat exchange stage to produce a first cooled quench oil and a second medium pressure steam. Heat can be transferred from at least a portion of the first cooled quench oil in a third heat exchange stage to produce a second cooled quench oil and low pressure steam. A total heat duty generated in the first heat exchange stage, the second heat exchange stage, and the third heat exchange stage can be equal to QT1 and a heat duty generated in the first heat exchange stage and the second heat exchange stage can be ≥0.5QT1 joules/sec.

    Abstract: Turbine fuel provided for large-scale land based turbines used by utilities for producing electricity and desalinated water, and for large mobile engines and turbines in marine and remote applications where only liquid fuels are available. Use results in less corrosion, ash formation and emissions (NOx, SOx, CO2 and noxious metals) than firing contaminated heavy crude, refinery residual oils or high sulfur fuel oils. Manufacture is by decontaminating crude oils, non-conventional crudes, and other highly contaminated feeds. Each fuel is produced as a single product of unit operations, not ex-plant blend of various refinery products, yet using an apparatus configuration less complex than conventional crude oil refining. These fuels can be fired by advanced high efficiency turbines of combined cycle power plants having hot flow paths and heat recovery steam generation systems susceptible to corrosion, which systems cannot otherwise risk contaminated heavy crudes or refinery residual oils feeds.

    Abstract: Disclosed herein is a method of estimating a property of a hydrocarbon comprising the steps of: preparing a liquid sample of a hydrocarbon, the hydrocarbon having asphaltene fractions therein; precipitating at least some of the asphaltenes of a hydrocarbon from the liquid sample with one or more precipitants in a chromatographic column; dissolving at least two of the different asphaltene fractions from the precipitated asphaltenes during a successive dissolution protocol; eluting the at least two different dissolved asphaltene fractions from the chromatographic column; monitoring the amount of the fractions eluted from the chromatographic column; using detected signals to calculate a percentage of a peak area for a first of the asphaltene fractions and a peak area for a second of the asphaltene fractions relative to the total peak areas, to determine a parameter that relates to the property of the hydrocarbon; and estimating the property of the hydrocarbon.
