Multiphase gMAX® Desanding

The gMAX Systems multiphase desanding unit is designed to treat a combined gas/liquid flow with gas flows up to 100%. The inter-nal geometry of the gMAX® hydrocyclone is extremely important in multiphase applications and is driven by detailed knowledge of the fluid properties, multiphase flow regime, and allowable pres-sure drop and separation efficiency requirements. gMAX Systems has developed physical models based on empirical data and in-dustry knowledge of multiphase flow.

Wellhead Desanding

In order to protect downstream production equipment, multi-phase desanding units can be located at several locations in the production train. Multiphase units that are located upstream of the production choke are called wellhead desanding units.

These are usually high pressure, multiphase, harsh duty applica-tions which severely challenge the reliability and performance of the separation equipment. Wellhead desanding systems employ single insert or multiple liner designs with design pressures to 15,000 psig. Both methods are field proven and include an inte-gral or separate accumulator for solids collection. Fit for service valves and instrumentation allow for safe operation.

Wellstream Desanding

When placement upstream of the choke is not pos-sible, the optimum location would be in the wellstream prior to the production separator. Wellstream Desand-ing is typically a multiphase application similar to the wellhead but usually at much lower operating pres-sures.

Each engineered system is designed to meet or ex-ceed applicable standards. gMAX Systems can offer almost any material of construction including carbon steel and exotic alloys. Hydrocyclone liner material is wear resistant alumina ceramic or silicon carbide lining depending on the application.

TurnDOWN™

In order to accommodate large turndown requirements that ex-ceed 50:1, gMAX Systems offers its TurnDOWN™ design. Turn-DOWN™ allows for continuous operation without ever shutting down the vessel. This is accomplished by compartmentalizing the overflow section of the desanding vessel. Isolation valves are opened or closed to adjust the number of liners in operation de-pending on the system flow rate and pressure drop.

Company Overview

Recently, Krebs Engineers formed gMAX Systems to provide sep-aration technologies to the Upstream Oil & Gas Market. Originally founded in 1952 as Krebs Engineers, the company has bee the driving force in hydrocyclone technology for over 50 years. Ini-tial application of this technology was in mineral processing and water desanding fields. gMAX Systems has installed more than 120,000 hydrocyclone systems worldwide.
