28 Measurement and Testing Effortless vapour pressure analysis


BARTEC BENKE’s RVP-4 Reid Vapour Pressure Analyser is designed to analyse petroleum and various high pressure applications for liquids from natural gas. It can also work with highly viscous samples, such as crude, without the need for additional wash cycles. RVP-4 can also measure vapour pressure at different temperatures due to its in-built temperature control unit, for example, true vapour pressure (TVP) at storage tank facilities.


BARTEC’s RVP-4 includes an ASTM compliant piston design, with a 4:1 expansion and an extremely precise and rugged measurement cell offering an extremely high level of performance because of the cell’s optimized assembly. This analyser requires virtually zero maintenance because of its integrated temperature control, insulating system and the absence of oil baths or pumps. The instrument’s low sample consumption also makes maintenance easier. The peltier is cooled down either by the analyser system itself or a coolant which enables RVP-4 to operate at a wide range of inlet temperatures. RVP-4 can perform heat tracing, self-monitoring and failure diagnosis and create validation reports for quality assurance purposes. RPA-4 is easily programmed via analogue or digital inputs and can be interfaced with Modbus/RTU and Modbus /TCP (bidirectional) and remote access is possible through Ethernet (VDSL or FOC is).

lead in a new era. The UV


and UV/VIS devices are a gain for every workplace in many respects. No matter whether they are used for disinfectant control, waste water and raw water treatment, drinking water treatment, the analysis of boiler and cooling water or for pool water control and swimming pool water treatment: Water analysis has never been easier with the XD 7000 and XD 7500.


Everything the user needs comes from a single source including the low-cost, barcoded cell test. Anyone can select the correct test method directly from the instrument. Using the external barcode scanner, the suitable analysis method can also be selected on reagent packaging, in the Lovibond®


Drone mounted, industrial emissions measurement


technology moves into production phase Aeromon, the company behind the compact and customisable emissions measurement devices that can be used in drone- mounted, hand-held and fixed configurations to reveal hidden industrial emissions, has announced the launch of its first commercially available product. The company aims to help industrial operators in maritime, oil and gas, waste and recycling, and pulp and paper mitigate environmental harm and meet emissions regulations in a low-cost, effective, and safe way.


“Aeromon has created the first FSC (Fuel Sulphur Content) measurement solution in the world that can be deployed on both fixed and rotary wing drones. This means industrial operators can select an emissions measuring solution with the cost point and operational capabilities they need to truly understand how their actions impact the environment – and what they can do to lower these effects,” said Aeromon CEO Teppo Virkkula.


“Our solution is already being used by the European Maritime Safety Agency to monitor maritime ships’ fuel sulphur content. We want to give industry the tools it needs to take control of fugitive emissions. We have invested significant time into building a completely new solution supported by a robust supply chain, partner network and distribution channels that can scale with future demand. We are ready to help industry tackle the challenge of fugitive emissions for the long-term,” he concluded.

with specifically requested barcoded templates for your own SOPs. The instruments automatically recognise the most common cuvettes in the most common sizes, report the use of an incorrect cuvette or adjust the measuring range. This makes annoying detours and time-consuming extra work processes a thing of the past.


Handbook of Methods offers valuable support for many analytical questions and applications. Countless technical details such as the UV and UV/ VIS optics or the light sources via tungsten halogen or xenon flash lamps turn the spectrophotometers into premium instruments as an economical system solution.

The instruments of the XD series also offer support for analytical quality assurance. User-defined calibration, password control and automatic logging are just some of the options. In addition the instruments provide simple user guidance and global usability thanks to multilingualism on all important levels. Besides, the Lovibond®


As of February 18th, industrial operators will be able to map fugitive emissions across a wide range of land-based and maritime locations, including those that have been traditionally difficult to access. Shipments are scheduled to begin by the end of February, with the company’s first distributor already in place for Spain and Portugal.


”We want to provide our customers with the best possible products and services to fulfill their current and future needs,” says Juan Carlos Cuchillo, Division Manager Analytica & Environmental at Izasa Scientific Spain and Portugal. “We have noticed increasing demand for emissions monitoring in our market and we were impressed by the new capabilities that Aeromon solution provides. We were happy to partner with Aeromon,” he concluded.


Aeromon’s modular BH-12 emissions measuring device can easily switch between airborne, hand-held and fixed configurations. The modular device enclosure can be configured to measure and visualise more than 70 different types of gases and particulate matter. Aeromon’s cloud service makes adjustments for local weather conditions, mapping potential leakage points and fugitive emissions hotspots on visualised maps of the monitoring areas.


The company was awarded the 2018 Frost & Sullivan Customer Value Leadership Award for developing “top-notch sensor measurement solutions with efficiency, reliability, and versatility unmatched on the market.” The company has successfully concluded pilots with a number of commercial operators, including Stora Enso, Gasum, and UPM.

A game changing pH electrode that can be relied upon


Refex Game Changing


Long Life Sensors for O+G/Petrochemical wet processes


Best for all Refinery/Petrochemical wet processes.


• Long Life • Accurate • Maintenance Free • Non Porous


Reference Interface


• Hydrocarbon Resistant • H2S Sour Water Resistant • Knick/Refex • Yokogawa/Refex • Emerson/Refex • ABB/Refex • Swan/Refex • CM42 Endress/Refex


Especially challenging are all oil and gas refinery applications and also petrochemical processes like ethylene quench waters these can be highly corrosive requiring accurate pH measurement and controls to counter costly corrosion damage to the plant.


email: For More Info, email: email:


Oil and gas refineries and ethylene plants processing petrochemicals where quench waters account for a vast majority of the waste streams are very difficult, yet very important locations in which accurate pH measurement and control is needed to counter against costly corrosive damage at the plant. Sour waters tested at these locations will be contaminated with hydrocarbons and contain up to 4% hydrogen sulphide with temperatures of 80 –100˚C.


Other tough places where pH measurement is a vital yet very tricky requirement include sulphur recovery units, low, ionic and corrosive boiler feed waters, overhead blow down sour condensate waters, effluent treatment plants with oily discharges and desalter waters in which potassium chloride (KCl) salt is removed by electrolysis. Contaminants such as these will quickly foul and poison any pH sensors with porous reference junctions, so regular ‘fire fighting’ in the form of cleaning, recalibration and expensive and time consuming electrode changes are regular occurrences. The electrode’s “weak link” component is always the porous reference junction “diaphragma” where there is a liquid to liquid contact and exchange. Effectively, this is built in obsolescence of all pH sensors.


A solution is at hand. Refex Sensor’s pH/mV sensors have a hard non porous ionically conductive interface/barrier that replaces the now obsolete porous junction (diaphragma). This unique interface barrier doubles as an immobilised electrolyte that protects the mV integrity of the AgAgCl reference by preventing all liquid/liquid contact and exchange between the KCl reference electrolyte that is separated by the interface barrier from the oily/sulphurous corrosive waters being pH controlled.


The Refex non-porous / long life pH sensors are totally resistant to HC fouling and H2 S poisoning. The highly reliable Refex pH


electrodes remain accurate and low maintenance and perform well many times longer than other pH electrodes in the most extreme oily/sulphurous corrosive waters even at high and varying temperatures and pressures. These electrodes are compatible with Yokogawa, Swan, Knick, Emerson and ABB instruments.
