Described herein are systems and methods for control of an overhead crude section of a hydrocarbon refining process. In one aspect, the method comprises monitoring a plurality of operating conditions of an overhead crude section of a refinery; determining hydrogen chloride and amine conditions of the overhead crude section of the refinery at current operating conditions of the overhead crude section; determining a plurality of fields of action by simulating a variation of one or more of the plurality of conditions; determining a risk indicator of salting for each of the plurality of fields of action; and providing a recommended change in operation of the overhead crude section to one of the plurality of fields of action while adhering to one or more constraints.

System and method of predictive analytics for control of an overhead crude section of a hydrocarbon refining process

A system and method are outlined for controlling and optimizing chemical injection into a process unit to control fouling. The method uses an optical device to measure the fouling propensity of the process fluid at various points within the process unit. The measurements are compared with one another and prediction methods are used to evaluate the fouling potential within the unit, and determine the proper chemical dosage. Antifoulant chemical is then introduced into the unit to control the rate of fouling. The method and application continue on a frequent basis to maintain optimal fouling control within the unit.

Application of visbreaker analysis tools to optimize performance

A method includes assessing corrosion in a refinery operation having a piping network. Assessing can include identifying in a petroleum sample a presence and an amount of a species determined to be potentially corrosive to corrodible equipment in a refinery. A corrosion risk presented by the presence, the amount, and the boiling point of the species is determined. And, the corrosion risk is evaluated in view of piping network information. A system for implementing the method is provided, also.

Corrosion assessment method and system

A methodology and system is disclosed which addresses outstanding needs of refiners to process cheaper crudes or blends of crudes. This method and system comprises a number of steps, including characterizing the impact of various constituents in the crude which result in fouling of heat exchangers; estimating model parameters; monitoring and predicting qualitative and quantitative performance; and determining optimal dosage of chemical treatments.

Method and system for assessing the performance of crude oils

The present invention is directed to a method for producing an emulsified aqueous hydrocarbon solution comprising, providing a liquid hydrocarbon stream at a particular temperature and a separate water stream, mixing the water stream with a surfactant at a predetermined ratio, raising the pressure of the hydrocarbon stream to a pressure greater than the vapor pressure of steam at the temperature, spraying the water into the hydrocarbon stream at a pressure greater than that of the hydrocarbon stream in a pre-mix chamber; and passing the pressurized hydrocarbon-water mixture through a static mixing chamber.

Emulsified feedstock for hydrocarbon process units that incorporate spray atomization

The present invention provides a feedstock composition for increasing the efficiency of atomization in hydrocarbon processing that includes a water-in-hydrocarbon oil emulsion including a non-ionic surfactant capable of stabilizing the emulsion and having a hydrophilic-lipophilic balance of greater than about 12. The emulsion includes water droplets of about 5 to about 10 microns in diameter, the droplets being dispersed substantially uniformly in the hydrocarbon oil phase. These surfactants are capable of stabilizing the water-in-hydrocarbon oil emulsion under relevant temperature and pressure conditions for hydrocarbon processing. The inventive feedstock composition provides a metastable water-in-oil emulsion where expanding water vapor explodes under spray conditions where the system pressure is released, demolishing a larger oil droplet and producing smaller oil droplets.

Spray atomization

The present invention relates to additives for enhancing the lubricity of hydrocarbon fuel oils, the inventive additive composition including one or more of the reaction products of (i) an alkylated polyamine and (ii) urea or isocyanate, or the salt adducts of these reaction products. More particularly, the present invention provides for a process for improving the lubricity of hydrocarbon fuel oils, which are low in inherent lubricity due to treatment to reduce sulfur and aromatic components for improved emissions.
