ETS Deoiling Hydro-Cyclones balance oil removal efficiency and overall capacity to ensure that separation requirements are met in the most cost effective and space saving way. The liners have been designed so that the Hydro-Cyclone is ultra-slim with a high number of liners to accomodate a given vessel size.
Our Deoiling Hydrocyclone liners are most commonly manufactured in Duplex Stainless Steel with surface hardening on the internal surfaces exposed to high fluid velocities to ensure long life in erosive systems. For extreme erosive applications, ETS offers liners manufactured from Stellite 6, Tungsten Carbide or Reaction Bonded Silicon Carbide, an advanced ceramic which will provide a wear life of up to 10 times that of a standard Duplex liner.
For applications requiring very high turndown, ETS offers its HTD compartmentalised vessel approach. Internal baffles 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 smaller vessels within a single vessel housing. This operation can be automated. The ETS HTD design has considerable benefits over traditional methods to increase turndown as it removes the need for either blanking liners or multiple vessels. In a typical installation, the ETS 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.
The MC Series Desanding hydrocyclone geometries have been developed in house, undergoing rigorous testing both in the lab and in the field and are now widely used globally. Desanding Hydrocyclone separation efficiency and capacity is a strong function of hydrocyclone diameter. The smaller the diameter, the smaller the particles that can be separated but the lower the capacity of each hydrocyclone. ETS offers four sizes within the MC Series range to ensure that an optimised solution can be offered for the diverse range of solids management applications encountered.
In the MC Series configuration, large numbers of small diameter Desanding Hydrocyclones are installed in a single vessel to achieve high sand removal efficiencies at high flowrates. In all cases, the liner packing is highly efficient which allows ETS to offer highly compact vessel designs. ETS manufactures the MC series hydrocyclone liners from engineering grade alumina ceramics as standard but for highly erosive applications, Reaction Bonded Silicon Carbide, an extremely hard wearing advanced ceramic, is used, providing typically 6 times the wear life of an alumina ceramic equivalent.
