Experience of Implementing an Intensifying Device on the Developed Mobile Well Production Treatment Unit

Abstract

The process of emulsion separation using an intensifying device tested on the developed mobile well production treatment unit was subjected to quantitative analysis followed by approbation. During tests, cassettes were mounted in the sump of the mobile unit with a distance of 5 mm (standard design) and 2.5 mm between the plates. Experiments were conducted with some variation: with the fluid entering the horizontal sump from the top and from the side, process temperature varying from 60 to 70°C, and with varying fresh water flow rates. It was found that the smaller distance between the plates ensures turbulent diffusion in the intensifying devices, leading to a more intensive oil treatment. It was also found that desalting processes proceed more intensively at 70°С than at 60°C and when fresh water flow rate is increased by 10 and 20%. A 30% increase in the flow rate of fresh water leads to an appreciable increase in the fraction of water in the treated drip oil, the desalting process deteriorates. The study showed that the use of intensifying devices with a distance of 2.5 mm between the plates leads to improved oil treatment: water cut decreased by 2–37% and the content of chloride salts decreased by 5–74% depending on the process.
