A method for selective removal of polycyclic aromatic hydrocarbons from oils obtained as a result of petroleum processing, including two separate processes: filtration through a porous carbon-containing bed comprising and filtration through microfiltration membranes. The method is particularly useful for purifying oils selected from unconverted oils obtained in hydrocracking processes, products of further processing of these oils, engine oil and used engine oil.

A gas oil separation plant (GOSP) and method for receiving crude oil from a wellhead and removing gas, water, and salt from the crude oil, and discharging export crude oil. The GOSP includes online analyzer instruments for performing online analysis of salt concentration in multiple streams in the GOSP. Based in part on the online analysis, the salt content in the export crude oil may be determined and the flowrate for wash water supplied to the desalter vessel may be specified.

The invention relates to various nonlimiting embodiments that include methods, apparatuses or systems for processing natural gas comprising a heavies removal column processing natural gas and light oil reflux. The overhead stream goes to heavies treated natural gas storage. The heavies removal column reboiler bottoms stream product is input to a debutanizer column. The debutanizer column overhead lights are input to a flash drum where the bottoms is pumped through a heat exchanger as a light oil reflux input to the heavies removal column, while the debutanizer reboiler bottoms product is stored as stabilized condensate. Alternatively, debutanizer column overhead lights are sent to heavies treated gas storage and the bottoms stream product goes to a depentanizer column, the overhead lights are pumped through a heat exchanger as a light oil reflux input to the heavies removal column, while the depentanizer reboiler bottoms product is stabilized condensate.

Systems and methods for separation of hydrocarbon containing fluids are provided. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the system uses a first gas separation followed by pressure reduction and then a second gas separation. Indirect follows the second gas separation and then three-phase separation.

According to one embodiment, a heavy oil may be processed by a method that may include upgrading at least a portion of the heavy oil to form an upgraded oil, where the upgrading includes contacting the heavy oil with a hydrodemetalization catalyst, a transition catalyst, a hydrodenitrogenation catalyst, and a hydrocracking catalyst to remove at least a portion of metals, nitrogen, or aromatics content from the heavy oil and form the upgraded oil. The method may further include passing at least a portion of the upgraded oil to a refinery operation.

A system and process for refining crude oil to produce higher-purity, cleaner-burning designer fuels with reduced emissions. The crude oil may be treated with viscosity-reductant additives, which reduces viscosity by up to 50% and increases API gravity by more than 2 points. The method of spray-cracking and vacuum-flashing of crude oil separates light end chains and heavy end chains inside the reactor. The vapor is condensed into designer fuels like bunker, diesel, jet/kerosene fuel, naphtha and gasoline fuel using multi-stage horizontal reverse condensate-condenser. The GVF centrifuges are configured to separate targeted fuels of desired density value as per their ideal fuel densities, which carry out centrifugal polishing to generate targeted fuel products of desired density and hydrocarbon molecules of desired purity values. These designer fuels are further treated with desulfurization additive. A method for automating daily selection of designer fuels and chemical-rich residuum from the process is disclosed.
