SCS Sample Conditioning System

Accuracy in the measurement of Natural Gas and Biomethane, has a strong relationship with an ability to collect and deliver a representative sample defined by science and standard.

The value of natural gas is determined by its quality.

What is a Representative Sample? A representative sample is simply a volume of natural gas whose makeup is consistent with that flowing in the pipeline from which it was taken. The widely accepted standard API 14.1; GPA 2166, API MPMS 14.1, ISO 10715 (Biomethane EN 16723 Part 1 and Part 2) and  ISO 6976 Natural gas defined that a representative sample must be:

1. Identical composition, or as identical as possible to the sample source stream.

2. Above the hydrocarbon dew point.

3. Representative of the vapor phase

3. Representative of the vapor phase only the of portion of the system being analyzed.

3. Representative of the vapor phase composition.

SCS is usually needed to adjust and adapt the condition of sample in order to get the best condition sample for analyzer.

Sampling systems specifically tailored to your application.

Each SCS is designed to meet specific application needs; ensuring sample integrity is maintained throughout the sample extraction and preconditioning process.

With a wide range of sampling equipment, including our retractable sample probes using Genie® Membrane Technology™, to separate unwanted liquid aerosols and droplets from the gas sample at process conditions.

International Gas Standard References

We overall assure the compliance with GPA Standard 2166-05, API 14.1,  API MPMS 14.1, for Gas and Biomethane ISO 10715, EN 16723 Part 1 and Part 2.

The intrusive liquid elimination is done inside of the pipeline therefore the gas and liquid are at pipeline conditions of pressure and temperature. This assures compliance with the International Gas Standard for removal of liquids from a natural gas sample. Use a membrane tipped probe whenever possible.

Sample Conditioning System Task

a) Extract representative sample of the gas (most important task)

b) Reduce (regulate the pressure )

c) Transport the sample to the analyzer

d) Protect the analyzer (analyzer “safety net”)

e) Control flow rate

f) Remove contaminants

Maintaining the sample in the gas phase at all times after extraction. At least 30 °F of de-saturation is required by the API 14.1 standard to keep away from the hydrocarbon dew point (HDP).

DDP 755 Sample extraction probes with membrane tip and probe regulator

Model 755™: The new technology

Genie® Probes™ provide a means to insert Genie® Membrane Technology™ directly into a pipeline for the purpose of separating unwanted liquid and particulate from the gas sample at flowing conditions; in compliance with industry standards.

The pressure regulator is built into the probe immediately downstream of the membrane, inside of the pipeline. Heat is transferred from the flowing pipeline gas to the regulator to prevent excessive Joule-Thomson cooling, helping to prevent condensation during pressure letdown.

The probe Model 755™ can be inserted and retracted from a pressurized line through a full opening valve.

Portable & permanent Analytically Correct™ gas sample probes with “Easy Turn” insertion

The PIP™ Model 702 is a simple, safe and economical solution to extracting a representative vapor phase sample from a source. Compared to the PIP™ Model 701, the Model 702 is designed for sampling at a specific depth in a pressurized pipeline so each length is customized to fit your application.

Our Pressure Balance™ technique effortlessly lowers the 702 probe into a pipeline without the force and bulky equipment associated with pneumatic or hydraulic methods.

Once installed, the installation housing can be replaced with a shorter housing to accommodate partial retraction of the probe during pigging operations.

One to Four Stage Heated Pressure Regulator

The four-stage regulator not effected by supply pressure changes!

The Model JTR-H™ is a revolutionary product containing four stages of heated pressure regulation in one 316 stainless steel housing. The design of the JTR-H™ separates it from current multi-stage heated regulators that are typically limited to two stages.

Specifically designed for gas analytical systems, the JTR-H™ prevents condensation of the sample gas from occurring as a result of Joule-Thomson (JT) cooling during the pressure reduction process of high pressure and high dew point gases or due to low operating or ambient temperatures.

Analytically Correct Engineered Systems (ACES) for natural gas

Each Analytically Correct™ Engineered Sample System is designed to meet specific application needs; ensuring sample integrity is maintained throughout the sample extraction and preconditioning process.

In compliance with the GPA Standard 2166-05, API 14.1, ISO 10715, API MPMS 14.1, ISO 6976 Natural gas.

Genie® Membrane Separators™; Liquid/Gas and Liquid/Liquid separators

The original brand known for sample conditioning and analyser protection.

FOR GAS SAMPLING

The Supreme 100 Series™ remove 100% of entrained liquid and particulate in gas samples, which allow only gas sample to flow to analyzers. This action protects analyzers and other sampling components against liquid damage. They offer an improved housing design for easy maintenance and the innovative Liquid Block Technology™ .

  • Liquid Block™ option
  • Low internal volume
  • Straight through Bypass
  • Built-in membrane retention

FOR LIQUID SAMPLING

The Supreme 200 Series™ remove 100% of suspended, immiscible liquids in liquid hydrocarbon samples, which allow only hydrocarbon liquid sample to flow to an analyzer.

  • Used exclusively in Series 200 Genies.
  • Maximum temperature: 300°F (149°).
  • Polypropylene backing for easy handling (check process compatibility).
  • Rejects immiscible liquids from hydrocarbon liquid, such as water in Diesel, Kerosene, Gasoline.

Coalescing/particulate filtration

High performance filters providing the utmost flexibility for coalescing/particulate filtration needs.

The Avenger 30 Series Filters provide sample conditioning and analyzer protection by using a disposable filter element to remove solids and liquid droplets from gas sample streams.

Genie® Membrane Technology with Liquid Block can be added as an option to the 30 Series filters, in addition to the disposable filter element. The use of Genie® Membrane Technology in these filters will remove 100% of entrained liquid, including aerosols, from the sample stream. The Liquid Block will completely valve off flow through the membrane to prevent liquid break-through from occurring in the presence of excess liquid.

Continuously self-cleaning filter

Highly efficient, self-cleaning liquid bypass filters.

The Tornado Model 602 is a continuously self-cleaning filter that protects analyzers from particulate in liquid samples. In normal operation, components of interest flow through the Tornado’s element to the analyzer. Contaminants are shed by the element and removed through the Bypass port.

Merlin Cyclone Separator

The MERLIN Pre-conditioning System is the ultimate protection for all on-line process gas analysers and equipment against particulates, liquids and mists found in process gases. It employs a patented and innovative technology to protect on-line gas analysers over a wide range of operating conditions. It is the solution to top productivity and to ensure significant cost savings in the plants.

The Merlin Cyclone Separator for Gas Applications

  • Good separation achieved in typical gas applications by large density diffrenences.
  • Ultra smooth cyclone geometry prevents splashing of liquid droplets which creates the mists that can be carried-over with the clean gas outlet.
  • Smaller particles less than 10 micron adhere/stick to the liquid film for enhanced separation

Ultimate solution for very dirty service dual stage Merlin Cyclone Separation
