during deodorisation process in steam reforming units


State-of-the-art process analysers to debut at ADIPEC 2021


BARTEC will display some of their State-of-the-art process analysers at the upcoming ADIPEC 2021 in Abu Dhabi on November 15-18 at the German pavilion in Hall 8 on stand 8760. The analysers are very well known and established both in Abu Dhabi and across the globe.


In certain areas of the world, crude oils with high level of salts exist. This crude oil must still be transported and refined and the high levels of salt pose problems if left untreated. De-salting technology is well established, but to be utilized effectively the need for quick and accurate measurements of the level of salt concentration is necessary. The immediate response of an on-line analyser allows the operator to use de-salters as efficiently as possible.


In remote areas with high ambient temperatures, the alcohol solvents used for measurement have forced end users into costly environmental conditioning to prevent solvent deterioration. The P-601 utilizes a single solvent approach with enhanced solvent characteristics, reduced chemical metering, and reduced maintenance items while still offering the repeatability and reliability of the original system.


The BENKE RVP-4 Vapour Pressure Process Analyser measures the vapour pressure of various petroleum products. Due to its design, it can be used for gasoline applications as well as for high pressure applications on natural gas liquids. It is also the best choice for applications for viscous samples such as crude oil without the necessity of implementing additional wash cycles. It is also possible to measure the vapour pressure at different temperatures e.g. True Vapour Pressure (TVP) for storage tank application.


The BENKE VISC-4 Viscosity Process Analyser continuously measures the kinematic viscosity of a product via the capillary method. Due to the outstanding performance and sample temperature stability of ± 0.02 K the VISC-4 is the best choice for highly accurate viscosity measurements e.g. lube oil production and fuel oil blending. This high level of accuracy results in cost reduction while improving product quality. The VISC-4 is suitable to handle samples with a viscosity of up to 1000 cSt at measurement temperatures of up to 100 °C.


HYGROPHIL® F 5673 is a high-quality, multi-channel fibre-optic hygrometer for measuring the moisture of trace humidity at low dew-point


temperatures in gases and liquid. The extremely robust temperature compensated moisture sensor was developed especially for natural gas applications and is now applied for many different applications.

Steam reforming is a process used to produce high amounts of hydrogen from methane. In this case, a superior quality of methane is needed to be purified from all odorant compounds present in natural gas. To ensure the accuracy of the deodorisation process, it is necessary to monitor the quantity of sulphur compounds emitted while being separated from the natural gas, however, until now, analysing this compound in such a humid and complex matrix has been problematic.


Chromatotec solutions quantify hydrogen sulphide at high concentration (low ppm) samples taken directly from natural gas pipes and very low concentrations (low ppb) sample taken after deodorisation. This dual-range system works with two different volumes of sampling loops. The analyser automatically switches between the two sampling loops to avoid the saturation of the system and/or signal.


The energyMEDOR is capable of analysing H2


S, mercaptans, DMS and/or total reduced sulphurs by directly collecting the sample at the vent. All the molecules are then separated by chromatography and detected at a very low level (ppb and/or ppm). In this specific case, the energyMEDOR is equipped with two sampling loops adapted to two different ranges of concentrations (0-1 mg/Nm3


to 0-50 mg/Nm3 and integrated in an ATEX-certified cabinet.


Thanks to its internal calibration system, the results are validated automatically and there is no need for manual intervention. The LCD colour touchscreen allows the user to view and edit the results directly in front of the analyser without opening it. The data are also automatically exported to a control room where the user is able to switch manually between the two sampling options instead of automatic mode.


The energyMEDOR detects sulphur compounds thanks to a long-life (up to 10 years) sulphur- specific Electrochemical Detector (ED). The solution analyses individual compounds and total sulphurs by the sum of all the compounds.

For precise pressure calibration when using an external compressed gas source, the Ralston ControlPak is a manual pressure controller that includes everything you need for fast, fingertip control - right where you need it. It features a large, pressure-balancing piston for precise pressure control, encased in a durable, tactical plastic that protects the controls from mud, intense heat and extreme weather and makes it easy to transport to any test site. Just pull up your truck, connect the ControlPak to a nitrogen tank, and start calibrating right at the site of your device under test.

With a wide pressure range of 200 kPa to 20 MPa, the ControlPak allows the testing of multiple devices in a single setup, including differential and static calibration, even at very low pressure. The fine-adjust piston, fill, balance and vent valves are clearly labeled and intuitively arranged in the unit, which also includes storage space for hoses, adapters and accessories. And all inlet and pressure port fittings are Quick-test, which require no tools or thread tape for secure, leak-proof connections.


Use with your current reference, or pair it with our industry-leading FieldLab Pressure Calibrator or a Field Gauge LC10 or LC20 pressure gauges for a complete calibration solution.
