Overview Cyclotech’s B20 Series Deoiling Hydrocyclone liner represents the state of the art in produced water treatment technology, a third generation geometry optimising the critical balance between oil removal effi ciency and capacity, ensuring that peak separation is achieved in the most cost effective and space effi cient manner. The B20 Series Deoiling Hydrocyclone is used to treat water streams containing up to 5,000 mg/l oil with a requirement to meet a discharge water oil content of 30 mg/l, or more commonly stretch targets of as low as 15 mg/l. For demanding

g process requirements, the B20 Series has been specifi cally designed for use with Cyclotech’s novel PECT-F® performance enhancement pre-coalescer and integrated with Cyclotech’s DeepSweep® CFU systems for ultimate separation performance. The B20 Series has proved itself to be one of the most effi cient Deoiling hydrocyclones available to the Oil & Gas industry with an enviable globally installed base on both onshore and offshore facilities. Principle of Operation A hydrocyclone has no moving parts and achieves liquid/liquid separation by virtue of a pressure drop across the unit. Oily water is forced under pressure into the inlet section of the liner via a tangential inlet port. This, together with narrow cyclone diameter, causes the fl uid to spin at high velocity, which creates a high g radial acceleration fi eld. Oil, the less dense liquid, is forced to the axial centre of the hydrocyclone to form a thin oil core. Through internal hydrodynamic forces and external differential pressure control, this oil core is removed counter currently via an axial port adjacent to the inlet while the clean water fl ow is discharged from the cyclone tail pipe. Hydrocyclone Liner Design The hydrocyclone geometry is critical to achieve optimal separation performance. Deoiling hydrocyclone designs cannot be scaled up, and so the B20 hydrocyclone liners are manifolded together in a common vessel to achieve the required system fl owrate. The ultra-slim external dimensions of the B20 Series liner has been designed to provide market leading liner packing effi ciency to maximize process throughput within a given vessel without compromising on performance. Cyclotech B20 Deoiling Hydrocyclone liners are most commonly manufactured in Duplex Stainless Steel. For erosive applications, Cyclotech offers liners with all inlet and tapered internal surfaces, exposed to high fl uid velocities, manufactured from a range of wear resistant materials. These include Stellite 6, Tungsten Carbide or Reaction Bonded Silicon Carbide, an advanced ceramic that will provide a wear live of up to 10 times that of a standard Duplex liner. High Turndown Vessel Design For applications requiring very high turndown, Cyclotech offers its HTD compartmentalised vessel approach. Internal baffl es are used to divide the vessel into either two or three compartments. Each compartment can be switched in or out of service using external valving, effectively providing a number of hydrocyclone liner banks within a single vessel housing. This operation can be automated. The Cyclotech HTD design has considerable benefi ts over traditional methods to increase turndown as it removes the need for either blanking liners or multiple vessels. In a typical installation, the Cyclotech HTD design can increase turndown from 3:1 to 10:1 for a two compartment and over 50:1 for a three compartment HTD vessel. New-Build Systems Cyclotech’s B20 Series Deoiling hydrocyclone systems form an integral part of our Produced Water Treatment capability. These systems can range from fully automated packaged systems to stand alone vessels. Standard pressure vessel designs are available at most design pressures and temperatures.
