Yokogawa Electric Corporation has announced that it has developed an explosion-proof version of the TDLS8200 probe type tunable diode laser spectrometer and will release it for sale on July 25 as part of its OpreX^TM Analyzer family. The TDLS8200 features low installation cost, high measurement stability, and high reliability, and is able to simultaneously and directly measure concentrations of two gas types (oxygen plus either carbon monoxide or methane) at high speed. Currently on offer are types that are capable of measuring temperatures up to 600°C and 850°C, and the addition of an explosion-proof version makes it possible to facilitate efficient combustion control and safe operation across a broader range of applications.

Any excess air that is supplied when controlling combustion in a heating furnace will absorb heat inside the furnace before exiting via the stack. In addition to resulting in heat loss, this can generate large volumes of nitrogen oxides and sulfur oxides, a source of air pollution. On the other hand, if insufficient air is supplied, complete combustion will not occur, resulting in energy loss, the emission of carbon monoxide and black smoke, and residual methane. Carbon monoxide and methane are flammable gases that can readily form an explosive mixture with air if allowed to accumulate inside a furnace.

As such, oil & gas, petrochemical, electric power, iron and steel, and ceramics plants need to monitor the concentrations of oxygen and carbon monoxide or methane inside furnaces in order to control and thereby ensure an efficient, environmentally friendly, and safe combustion process. However, the use of digital devices in zones where combustible gases reach concentrations that result in the risk of an explosion is limited by regional laws and regulations as they have the potential to ignite such gases. To address this need, Yokogawa has developed this latest version of the TDLS8200 probe type tunable diode laser spectrometer.

The most significant feature of the TDLS8200 is its dual laser light sources and optics, which give it the ability to simultaneously measure oxygen plus either carbon monoxide or methane concentrations for combustion control. Its direct measurement system relies on the use of lasers, which are easier to maintain than conventional sampling systems and are more robust than catalyst-based sensors. This ensures stable, simultaneous, and lossless measurement. Also, by adopting a probe design with no sampling device, it is easy to install and replace.

The explosion-proof TDLS8200 that is being released for sale conforms to the IECEx explosion-proof standard of the International Electrotechnical Commission (IEC), the FM explosion-proof standards of the United States and Canada, and the EU’s ATEX explosion-proof directives. Compliance with these regulations enables the device to be used in zones where combustible gases reach concentrations that result in the risk of an explosion. Going forward, Yokogawa will work toward acquiring certification for the explosion-proof standards of other regions and countries too.

Promass Q 300 provides the highest measurement accuracy for mass flow, volume flow and density. Being the preferred choice for custody transfer applications, it has also been optimized for liquid applications where entrained gas is known to be present. The compact transmitter offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. Heartbeat Technology ensures safe processes.

• Measuring principle operates independently of physical fluid properties such as viscosity or density

• Highest measurement performance for custody transfer, density and under tough process conditions

Device properties

• Mass / volume flow: measurement error ±0.05 % (opt.) (PremiumCal)

• Density: measurement error ±0.1 kg/m³ (opt.)

• High turndown due to low pressure loss/zero point

• Compact dual-compartment housing with up to 3 I/Os

• Backlit display with touch control and WLAN access

• Remote display also available

Benefits

• Secured measuring quality – unmatched accuracy of mass flow, volume flow and density

• Optimized performance for liquids with entrained gas – MFT (Multi-Frequency Technology)

• Fewer process measuring points – multivariable measurement (flow, density, temperature)

• Space-saving installation – no in-/outlet run needs

   

   

   

Product  Details

Emerson has launched the TESCOM™ Anderson Greenwood Instrumentation H2 Valve Series for hydrogen applications up to 15,000 pounds-per-square-inch (psi) (103.4 megapascal (MPa)). The new solution reliably isolates process pressure in high pressure gas applications such as hydrogen fueling stations and tube trailers, reducing fugitive emissions and improving safety.

As it moves from tank to pump, hydrogen is transferred at pressures of up to 15,000 psi (103.4 MPa). To protect personnel and prevent leaks, it must be effectively controlled and isolated. The Double Block Bleed (DBB) valve’s positive double block arrangement provides two layers of positive shutoff that shield maintenance staff from high pressure during instrument maintenance. Its modular design reduces the number of potential leakage points, and the reinforced sealing technology reduces the risk of fuel entering the atmosphere through the valve stem.

Among the cleanest fuels when produced using renewable resources, compressed hydrogen gas is used to power fuel cell electric vehicles (FCEVs). In 2021, 142 new hydrogen refueling stations began operating, the biggest increase in a single year, raising the total to 685 active stations worldwide. And, in January 2022, Global Market Insights Inc. predicted that the FCEV market will exceed $15 billion by 2027. To meet this growth demand, fueling station original equipment manufacturers (OEMs) must source reliable, high-performance components to ensure overall equipment effectiveness and ensure station safety.

“Given the pressures that hydrogen is subject to in these applications, it’s critical that equipment operates safely and reliably, every time. That’s why we’re committed to specifically developing components to help our customers effectively store and precisely control compressed hydrogen gas,” said Rob Lindquist, director of global marketing for TESCOM precision fluid control at Emerson.

The hand-operated, maintenance-free design of the hand valves and double block and bleed valves in the H2 Valve Series minimizes maintenance and downtime. With low operating torque and adjustment-free seal technology, these hand valves deliver a low cost of ownership in a compact solution.
