Following the recent start-up and commissioning of ASaP’s revolutionary, patented Phazer LNG probe-vaporizer at an FLNG vessel with 2.4 million tonnes liquefaction capacity, we plotted the results of our latest Phazer model and the previously installed probe-vaporizer. Even with the current low prices of LNG, in this example we are looking at a difference in[…]
Sample probes are designed for extracting a representative portion from the gas sample source in a pipe to the sampling system, and finally the gas analyzers.
Sample gas probes form a critical point between process and sample conditioning and analysis system. They extract sample gas from the process stream and supply it to the analysis system. They should already remove undesirable particulates at the sampling point and avoid cold spots thus preventing false measurements.
Sample probes for sample extraction are an utmost important part of the sampling system. Liquid carryover from the pipeline into the sample system should be prevented when sampling gas as it can directly impact the analysis and damage a gas analyzer.
Industry standards state that the equipment used to remove the liquid from the sample must be operated at flowing temperature and pressure conditions.
In addition it works as a filter, keeping dirt, and unwanted moisture out of the extracted gas sample. A well designed probe for sample extraction, reduces sample times, gets a better response time, reduces sample volume, and eliminates dead volumes.
Factors to take in account when choosing a gas probe for sample extraction:
- Toxic or corrosive components
- Climate conditions
- Accessibility for the field engineers
- Safety conditions
Benefits of a well designed sample probe:
- Reduced sample times
- Better response times
- Reduced sample volume
- Eliminate dead volume
ASaP can provide you a full service package including analyzers, service and system integration. Some of the probes, like the Phazer or the Flare Gas Probe are manufactured by ASaP, an ISO 9001:2015 certified company in the Netherlands.
Genie 133 Membrane Separator – A+ Corporation
The GPR™ consists of a housing and a membrane-tipped probe regulator. The housing is installed in a depressurized pipeline through a vertically mounted thread-o-let or flange
LNG probe-vaporizer for accurate LNG samples – The Phazer
The Phazer conforms to ISO 8943:2007 and surpasses NEN-EN 12838:2000. Your LNG measurement is only as accurate as your provided sample… The Phazer is the only cryogenic LNG probe-vaporizer that provides verifiably accurate and representative LNG samples at 0,5 barg.
Flare Gas Probe – Sample take-off and extreme sample conditions
One of the successful developments of ASaP’s R&D department is the ASaP Inclined Fall-back Stokes’ Law Flare Gas Probe. This Flare Gas Probe solves the ‘old’ problem of plugging and fouling the probe and the sample conditioning system and the gas analyzers downstream. It ensures that the analyzer system remains protected from unexpected fouling ensuring uninterrupted[…]
Vortex shedding – Not with Orbital VE technology
Accurate sampling starts at the sample probe. A typical probe used in process sample handling is a cylindrical piece of metal that is placed in the process pipe. One of the downsides of these conventional sample probes is the vortex shedding effect which means that a small Vortex gets formed at the tip of the[…]
Genie GPR Probe Regulator – A+ Corporation
The GPR™ consists of a housing and a membrane-tipped probe regulator. The housing is installed in a depressurized pipeline through a vertically mounted thread-o-let or flange
Genie 752 Direct Drive Thermowell Probe – A+ Corporation
The Direct Drive Model 752™ thermowell probe allows a resistance temperature detector (RTD) to be inserted and extracted from a pressurized system through a full opening valve.
