  • Patent number: 10370948
    Abstract: The invention relates to injecting steam into crude oil for several benefits, primarily of which is to remove salt by transferring the salt into the condensed water from the steam. Steam transfers salt via a different transfer mechanism and therefore doesn't require the high shear mixing of conventional water injection systems. As such, steam injection through a variety of procedures, is more efficient at gathering salt into water that itself is easier to remove from the crude oil.

  • Patent number: 10336951
    Abstract: A petroleum desalting process in which the oil/water emulsion layer which forms in the desalter vessel between the settled water layer and the settled oil layer is separated into the oil and water components by contact with a heated high boiling hydrocarbon to break the emulsion and vaporize water from the emulsion in a flash drum. The vessel has an emulsion outlet for removing an emulsion stream from the emulsion layer and a conduit connecting the emulsion withdrawal port to an inlet of an optional settling drum to effect and initial separation into an oil-enriched phase and a water phase with the oil-enriched phase led to the flash drum.

  • Patent number: 10179880
    Abstract: Particulate mercury, in the form of metacinnabar, is removed from crude oil by thermally treating the crude oil at temperatures in a range from 150° C. to 350° C. and at a pressure sufficient to limit the amount of crude vaporizing to no more than 10 wt. %. In the thermal treatment, the particulate mercury is converted into elemental mercury, which can be removed by directly adsorption from the crude onto a support. In one embodiment, the elemental mercury can be removed by stripping the crude with a gas, and then adsorbing the mercury onto a support. The crude oil can be optionally treated prior to stabilization and contains 0.1 wt. % or more of C4-hydrocarbons. Following the thermal treatment, the treated crude is cooled and the pressure is reduced. The C4-hydrocarbons then vaporize from the crude and carry the elemental mercury with them. The elemental mercury in this hydrocarbon gas stream may then be removed by a solid adsorbent.

  • Patent number: 10077937
    Abstract: A method to produce LNG at straddle plants. In contrast to known methods, there is provided a slipstream of a high pressure, pre-treated, pre-cooled natural gas stream to a straddle LNG plant section. The slipstream is further cooled, and processed in a high pressure column to a methane content of 85% or 85 plus by mole. The processed stream is further treated to remove carbon dioxide. The de-carbonated high pressure stream is further cooled in a heat exchanger by a counter-current vapor fraction of the expanded gas before entering an expander apparatus. The processed, treated and cooled gas is expanded into a separator. The produced LNG fraction is pumped to storage. A portion of the LNG fraction is used as a reflux stream to the high pressure column. The cold vapor fraction from the separator flows through counter-current heat exchangers, giving up its coolth energy before being re-compressed into the high pressure transmission gas pipeline.

  • Patent number: 9199251
    Abstract: An atmospheric vertical oilfield tank designed to pre-condition oilfield fluid streams. Flow enters on tangent a vertical cyclone tube located within the tank and rotates inside the tube. Solids fall downward out of the tube to the bottom of the tank; gases exit upward out of the tube and vent from the tank. Liquids exit the cyclone tube tangential to the ID of the tank, additional solids separation due to impingement, and the liquid flows into the body of the tank where flow slows to allow for settling of solids. Solids are periodically removed from the bottom of the tank. The liquid flows over the top of multiple vertical flow dividing tubes located at the same elevation within the tank, creating separate and equal effluent discharge streams. The tank is taller than destination vessels to provide the height differential necessary to create flow into subsequent tanks without using pumps.

  • Patent number: 9157035
    Abstract: A portable, semi-portable, or permanent system for removing BS&W from crude oil at the local production or bulk storage site. A demulsifier is added to the crude as it enters a low shear pump which pumps the mixture through a plate and frame type heat exchanger where the incoming crude is preheated using outgoing heated and dehydrated crude. Then the incoming crude enters an oil-water separator where it is further heated by a secondary heater within the separator and passes through a special coalescing section. Water and basic sediment separate from the crude are discharged from the bottom of the separator. The heated dehydrated crude exits the separator, flows back through the heat exchanger where it is cooled as it preheats incoming crude, and then is pumped to clean oil storage. BS&W and flow monitors on the incoming crude and outgoing crude are used to control operation of the system.

    Abstract: Systems and methods generate steam in hydrocarbon recovery operations and may further enable emulsion separation and product upgrading. The methods rely on indirect boiling of water by contact with a thermal transfer liquid heated to a temperature sufficient to vaporize the water. Examples of the liquid include oils, recovered hydrocarbons, liquid metals and brine. Heating of the liquid may utilize circulation of the liquid across or through a furnace, heat exchangers, or a gas-liquid contactor supplied with hot gas. Further, a solvent for bitumen introduced into the water may also vaporize upon contact with the thermal transfer liquid.

    Abstract: Heavy crude oils having high sulfur content and viscosities are upgraded by a hydrodesulfurization (HDS) process that includes microwave irradiation of a mixture of the sour heavy crude oil with at least one catalyst and optionally, one or more sensitizers, and irradiation in the presence of hydrogen. The process is also adapted to microwave treatment of hard to break emulsions, either above ground or below ground where water-in-oil emulsions are initially formed, followed by the catalytic hydrodesulfurization promoted by application of further microwave energy to the demulsified crude oil stream.

  • Patent number: 8449776
    Abstract: Our idea is a new procedure that can be used to clean up and recover oil from spills or oil leaking from damaged ships or rigs. The reclamation is accomplished by restoring the oil's light density. This is accomplished with density control by adding light cycle oil, (LCO), with a density of 0.82 g/ml, to the oil being recovered for the purpose of reprocessing in refineries. Recovery is made possible through the application of solubility rules found in organic chemistry. LCO is a mixture of many different molecular weight hydrocarbons that have many different numbers of carbons in their chains, branches, or rings. Each of these hydrocarbons dissolves a small part of the oil preparing the mixture for collection and reprocessing as refinery feedstock. Furthermore, this idea can prevent the need for landfill storage and offset the cost of recovery.

  • Patent number: 8425777
    Abstract: A method of separating includes mixing a fluid into a mixture that has been separated from an oil well stream and that includes water, oil, and gas. The mixture including the fluid is fed into a separator and allowed to separate into a water phase and an oil/fluid phase. The cleaned water phase is removed from the separator via an outlet for water. The oil/fluid phase is subjected to a separation step separating the oil/fluid into an oil phase and a gaseous phase, from which gaseous phase the fluid is recovered by a condensation step and recycled for injection into the mixture. The separator is a liquid-liquid/gas separator in which the pressure is in the range of 0.5 bar to 25 bar, while the mixture including the fluid is separated into the water phase and an oil/gas phase.
