The quality of sand and water discharged into the sea or local water course is subject to increasingly strict legislation, making the removal and disposal of sand or other production solid materials an important environmental factor in addition to the benefits in protecting downstream process equipment. They are used to protect downstream equipment, facilitate produced water injection, prevent sand build up in separators and pipelines and protect sensitive items such as pumps and heat exchangers.
Our solid/liquid hydrocyclone has been developed for the efficient separation and cleaning of particles denser than water. The system is extremely versatile and can accommodate a variety of fluid rates, solid types and concentrations, as well as widely differing pressures and temperatures. As a result they are particularly suited for the unique applications found in the oil and gas markets, such as the treatment of produced, aquifer deballast, refinery water and other sand cleaning operations. They are used for primary separation on river or estuary intakes, for water injection systems. An important benefit of our solid/liquid separator is its compactness and light weight. With no moving parts, it can offer significant savings in both capital and operating costs and can be retrofitted into existing field developments.
Our units can be supplied in super abrasion resistant materials, polyurethane or steel, depending on the specific application and the erosive nature of the solids to be separated. Super abrasion resistant materials and polyurethane hydrocyclones are fully interchangeable
The hydrocyclones are typically installed within pressure vessels and internally supported by tube plates. For the smaller diameter cyclone range our design allows many hydrocyclones to be packed into the vessel giving a high unit flowrate.
The vessel inlet chamber is located within the vessel center section, allowing the clean fluid to flow out of the top section, with the removed solids accumulating in the bottom section. Typical pressure drops are between 1–5 bar
