A method for producing a supercritical water (SCW)-treated product is provided. The method comprising the steps of introducing a crude oil stream and a water stream to a supercritical water process, wherein the crude oil stream can undergo conversion reactions to produce the supercritical water (SCW)-treated product, wherein the SCW-treated product includes an increased paraffin concentration as compared to crude oil stream. The method further includes the step of introducing the SCW-treated product to a steam cracking process, wherein the SCW-treated product can undergo conversion reactions to produce furnace effluent.

An integrated hydrothermal process for upgrading heavy oil includes the steps of mixing a heated water stream and a heated feed in a mixer to produce a mixed fluid, introducing the mixed stream to a reactor unit to produce a reactor effluent that includes light fractions, heavy fractions, and water, cooling the reactor effluent in a cooling device to produce a cooled fluid, depressurizing the cooled fluid in a depressurizing device to produce a depressurized fluid, introducing the depressurized fluid to a flash drum configured to separate the depressurized fluid into a light fraction stream and a heavy fraction stream. The light fraction stream includes the light fractions and water and the heavy fraction stream includes the heavy fractions and water. The process further includes the step of introducing the heavy fraction stream to an aqueous reforming unit that includes a catalyst to produce an aqueous reforming outlet.

A slop oil treating device, including a pretreatment device, a solid-liquid separator, a demulsification nucleus-increasing treating device, a squeezing filter press, a three-phase separator, a buffer tank, a feeding pump, a circulating pump, a conveying pump, and an outputting pump. The slop oil is subjected to a pre-heating at a temperature ranging from 90 C. to 92 C. in the pretreatment device, and then conveyed to the solid-liquid separator for separation. Solid residue after a first-stage separation enters the squeezing filter press for solid-liquid squeezing. The squeezing filter press discharges the squeezed solid residue and conveys the squeezed waste water to the demulsification nucleus-increasing treating device. Oil and water after the first-stage separation enter the three-phase separator for second-stage high-speed centrifugal separation. Oil separated by the three-phase separator is conveyed to the buffer tank, and conveyed to a storage tank through the outputting pump.

A washing and desalting device includes a first shell and a plurality of filaments. The first shell has a first receiving cavity and is provided with a liquid inlet and a liquid outlet that communicate with the first receiving cavity. The plurality of the filaments is provided in the first receiving cavity, and the length direction of each of the filaments is consistent with that of the first receiving cavity. The device can be incorporated in a washing and dehydrating system.
