摘要： A system and method to partially vaporize a process or feed water stream does so in a liquid pool zone of a vessel as the stream comes into contact with a heating medium that is less volatile than the process stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the process stream is partially vaporized, any solids present in the process stream together with the unvaporized process or feed water stream move into the heating medium. These solids and unvaporized liquids may be further removed from the heating medium in the pool or in the pump-around loop. The vaporized process stream can be further condensed. Any heat recovered can be used to pre-heat the process stream or in the pump-around loop's heater in case of mechanical vapor recovery.

摘要： A vessel for treating an oil-in-water inlet stream houses an inlet flow distributor arranged to direct an inlet flow toward a perforated baffle of a coalescing section, the coalescing section housing a packing and being arranged upstream of a second baffle; a flotation section arranged to receive a flow exiting the coalescing section and being divided by one or more perforated baffles; and an outlet water collecting pipe arranged to receive a flow exiting the flotation section, the outlet water collecting pipe having one or more openings located along its length. The coalescing section may be divided into two sections, with one section preferably housing a different pre-selected sized packing than the other section. The flotation section may include one or more gas-inducing devices. A solid baffle may be arranged downstream of the second baffle and ahead of the flotation section to provide single or dual flow through that section.

摘要： A system and method to reboil a process or feed water stream in a distillation system does so in a liquid pool zone of a vessel as the stream is removed from a distillation column and comes into contact with a heating medium that is immiscible with and less volatile than the process stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the process stream is partially vaporized, any solids present in the process stream together with the unvaporized process or feed water stream move into the heating medium. These solids and unvaporized liquids may be further removed from the heating medium in the pool or in the pump-around loop. The vaporized stream is returned to the distillation column.

摘要： A method to remove oil from an oily water stream includes the step of pressure controlling a release of dissolved gases from the stream as the stream passes through two or more stages of gas flotation treatment. The operating pressure of the first stage of flotation treatment is purposefully reduced relative to that of an upstream unit so that a certain controlled percent volume of dissolved gases is released. The operating pressure of the second stage of flotation treatment is then purposefully reduced relative to that of the first stage so that another controlled percent volume of dissolved gases is released. Any subsequent flotation treatment stage is at a lower operating pressure than that of the previous stage so that the subsequent treatment stage releases a controlled percent volume of dissolved gases. By controlling the operating pressure in this way, overall separation performance is improved.

摘要： An apparatus and method for separating water from an oil-water influx are provided. The apparatus includes a separation vessel having an inlet, an oil collection portion at its upper end, and a water collection portion at its lower end. Multiple high voltage tubes, each containing an electrode, are located within the oil collection portion. These high voltage tubes are staggered in length and held in place by perforated plates. The oil-water influx flows through the inlet of the vessel into the high voltage tubes, where it is subjected to an electrostatic field. The electrostatic field causes water droplets in the influx to coalesce and form a water out-flux which flows downwardly into the water collection portion of the vessel. The remaining stream of dehydrated oil flows upwardly to the upper outlet end. The oil collection portion of the separation vessel may be oriented vertically or at an angle.

摘要： A system and method for removing acetic acid and other short chain fatty acids described as organic acid from a rich mono-ethylene glycol (“MEG”) solution does so by stripping the organic acid from the rich MEG solution by contacting the solution with a gas, the gas being nitrogen or a fuel gas such as methane; and stripping the organic acid from the gas by contacting the gas with a caustic solution such as a dilute sodium hydroxide solution. The stripping steps take place in respective stripping columns. A portion of the gas exiting the gas/organic acid stripping column can be recycled to the MEG/organic acid stripping column to reduce total gas usage. A portion of the waste stream exiting the gas/organic acid stripping column can be recycled back to the gas/organic acid stripping column to reduce the amount of caustic solution used as well as the amount of waste.
