Systems and methods for crude oil desalting technology are provided. More specifically, systems and methods for the usage of waste heat from compression to treat high salinity water are provided. The systems and methods generate recycled water streams for desalter treatment. The systems and methods can treat high salinity waters from desalters and dehydrators. The high salinity streams are introduced to the compressed gas streams, where the waste heat causes the water portion of the water streams to evaporate, resulting in a fully or near-saturated gas stream and a concentrated waste water stream. The saturated gas streams are cooled and condensed, and low TDS water is separated from the gas stream in knockout drums. The low TDS water can be reintroduced to the desalting system as wash water, generating a circular water reuse.

The technology relates to the use of a high salinity produced water stream from a gas oil separation plant (GOSP), as a wash water stream for the desalter unit in a GOSP. The produced water stream is pretreated by a sequence of steps and subsequently desalinated by a ultra-high pressure reverse osmosis (UHP-RO) membrane. The UHP-RO produces a permeate stream and a reject stream. A portion of the permeate stream is reused as a wash water stream in the desalter unit of the GOSP.

A method for automating wash water rates into a desalter comprises the steps of collecting historical dry crude rates; collecting historical wash water rates; collecting historical salt content amounts, where the historical dry crude rates, historical wash water rates, and historical salt content amounts are from a historical time period; determining a percent wash water from the historical wash water rates and historical dry crude rates; developing a salt content versus percent wash water curve using the historical salt content amounts and percent wash water; developing a salt content predictive equation from the salt content versus percent wash water curve; programming the salt content predictive equation and the percent wash water equation into a distributed control system; and regulating a current wash water rate based on an expected salt content determined from the salt content predictive equation.

The utility model relates to the field of wastewater desalination, in particular to a wastewater evaporation desalter, and adopts the technical scheme that the wastewater evaporation desalter comprises a heating base, an evaporation tank, a tank cover, a driving motor, a radiating fin plate, a storage tank, a gas collecting pipe and a plum blossom stirring rod, the evaporation tank is mounted on the inner wall of an outer frame, and a threaded groove is formed in the upper end of the outer frame in a penetrating manner; according to the device, the plum blossom stirring rod is driven by the driving motor to fully stir salt-containing wastewater in the evaporation tank, so that the effect and the efficiency of evaporating and heating the salt-containing wastewater in the evaporation tank by the heating base are improved in an auxiliary manner, and high-temperature steam in the evaporation tank can be introduced into the gas collecting pipe through the gas collecting pipe; and the high-temperature steam in the gas collecting pipe is quickly cooled by the radiating fin plate, so that the steam is condensed into water, and the condensed water falls into the storage tank due to the weight of the condensed water so as to lift, so that the steam is recycled.

This technology relates to the treatment of a produced water stream to promote water circularity in a gas oil separation plant (GOSP). A wash water unit supplies a wash water stream to a desalter to desalt the crude oil in a GOSP. The desalter effluent stream is pretreated to produce a pretreated desalter effluent stream. Simultaneously, an untreated produced water stream is processed in a water oil separator (WOSEP) of a GOSP. The WOSEP produces a produced water stream and a recovered oil stream after separation. A portion of the produced water stream is pretreated and mixed with the pretreated desalter effluent stream resulting in a mixed stream. The mixed stream is desalinated to produce a permeate stream and a reject stream. The permeate stream is reused as a wash water stream in the desalter. The reject stream is recycled to either the WOSEP inlet or WOSEP outlet.

The technology relates to the pretreatment process of a high salinity produced water stream in a gas oil separation plant (GOSP). The produced water stream includes a salinity of up to 150,000 ppm of total dissolved solids (TDS). The treated produced water stream is processed by a desalination unit integrated in the GOSP, to produce a permeate stream with less than 5000 ppm of TDS and a reject stream. The permeate stream is reused as a wash water stream in the desalter unit of the GOSP, to desalt the crude oil or use it for other beneficial reuse purposes.

A method and assembly for improving and maintaining a seal between an insulating rod and a flange in a desalter entrance bushing assembly. The assembly includes an insulating rod with a shoulder for a biasing component, a hub nut with a spring seat for a biasing component, a biasing component, and a flange to which the insulating rod can create a fluid tight seal. The shoulder and spring seat can form approximately 90-degree platforms on which the biasing component can apply force when the hub nut is appropriately secured to the flange. The method includes threading the hub nut containing the biasing component into the flange. The nut is secured to a predetermined torque and the biasing component ensures that the seal is maintained during temperature and pressure fluctuations.
