Systems and methods for treating a rag layer in a gas oil separation plant. The method includes withdrawing the rag layer from a vessel proximate an oil water interface, conveying the rag layer to a separation device, and recycling separated oil from the separation device back to the gas oil separation plant process.

An apparatus for purifying water to be purified is provided with a tank with a bottom to receive sediment, an inlet connected to the bottom itself, at least one pump, outside the tank and connected to the inlet, at least one conduit disposed axially inside the tank, diverging upward and fluidically connected to the inlet to receive pressurized water fed by the pump, and a hydraulic accelerator/mixer assembly disposed in the tank and which connects the inlet to the conduit. The hydraulic accelerator/mixer assembly is configured to increase the speed of the flow of water to be purified, introduced into the tank.

A treatment process for remediating; contaminants in a mixture of contaminated fluids, including at least one liquid fluid and at least one gaseous fluid, includes the steps of: preparing a treatment composition containing at least 80 volume % of an aqueous solution containing at least one hydroxide compound at a collective concentration of 35-55 weight percent, and at least one organic acid selected from the group consisting of fulvic acid and humic acid at a collective concentration of 0.1-5 wt % of the treatment composition; adding a dosage of the treatment composition to a mixture of contaminated fluids including a liquid portion and a gaseous portion; and allowing the treatment composition to react with the mixture of contaminated fluids for at least 10 minutes. A pH of the treatment composition is at least 12.0

In one embodiment, an ice management system is provided for removing an amount of oil from a surface of a body of water. The ice management system includes an ice frame having an ice fence coupled with an ice cage, an oil skimmer device disposed within the ice frame, and an ice deflection assembly coupled with the ice frame. The ice deflection assembly includes an auger coupled with a motor. The auger includes a drum and a deflection mechanism, and the motor is configured to rotate the auger. The deflection mechanism includes a spiral flight or a series of tabs arranged in a corkscrew pattern about the drum. The ice fence includes a plurality of curved vanes. The curved vanes have a bent rectangular plate shape.
