High Pressure Sampling Systems Introduction

– Models 522 | 532 | 538 | 542 –

Analytically Correct Engineered Systems™ are tailored to the specific application and designed to ensure sample integrity is maintained throughout the sample extraction and preconditioning process. The High Pressure Sample System is an ACES™ tailored to the Natural Gas Industry. Consisting of a Genie® four-stage Heated Regulator™ in an insulated enclosure mounted on a Genie® Probe™. It is best suited to sampling natural gas at conditions near the hydrocarbon dew point and well above the cricondentherm. A typical application is the sampling of gas in midstream operations that is rich and at high pressure.


Genie® Membrane Technology™ on the tip of the probe separates liquid at source conditions to ensure a representative gas sample and to protect the analyzer by excluding contaminants from the entire sample handling system. Genie® Membrane Probes™ are designed to be safely retracted from a pressurized source without any special tools, so the Genie® membrane can be easily accessed and maintained. The GP series utilizes a housing with a foot valve for process isolation. The Genie® Direct Drive™ series is inserted and retracted through a full port process isolation valve.


The custom GPHV™, non-membrane probe is a fixed probe possessing a higher-pressure rating than the Direct Drive™ Series. The custom GPHV™ makes the Model 538 configuration the safest extraction system for applications ranging from 3,500 psi to 4,500 psi.

At source conditions near the hydrocarbon dew point the sample must be heated before pressure reduction for compliance with recommendations from industry standards to keep the sample temperature above the hydrocarbon dew point. This is accomplished by applying heat to the body of the regulator near the inlet port and by reducing the pressure in four stages to help compensate for the Joule-Thomson (JT) cooling effect and prevent condensation. Rounding off our ACES™ systems is a removable probe mounted enclosure that is insulated and heated to prevent ambient temperature from adversely impacting the sample.


High Pressure Rich Gas Sampling System Component Breakdown

Genie® Probes™
Our revolutionary Genie® Membrane Probes™ featuring patented Genie® Membrane Technology™ at the probe’s tip offers an Analytically Correct™ method for extracting a representative sample from a gas source near the dew point, in compliance with industry standards (API 14.1, GPA 2166 and ISO 10715). The custom GPHV™ is a fixed, non-membrane tipped, thick walled probe that is machined from a single piece of stainless steel and has a higher pressure rating.

Genie® Four-Stage Heated Regulator™
A+ pressure regulators are designed specifically for sample handling. The four stage regulator can be heated either with a 200 watt heating element or with a self-limiting (20 or 80 watt) heater block. The self-limiting heater block on the Model JTR-H™ is a small, simple, extensively certified device that provides a reliable heat source without temperature overload in small or densely populated enclosures. A proportional controller is used to regulate power to the 200 watt heating element in the Model 901-JTR™.

Insulated Enclosure
This case allows the sample pressure and enclosure temperature to be monitored at a quick glance, without having to remove the enclosure. For complete access to system components, one or both sides can be completely removed.
