Mitigating safety challenges in H2 and CCUS applications
Safe and reliable measurement devices to enhance process efficiency in the Oil and Gas Industry
Accidents in process plants often have fatal consequences for the environment, people and the equipment. Endress+Hauser's extensive portfolio and expertise in process and functional safety help you to reduce, detect, and eliminate random or systematic failures. Given the nature of the gases and the risk for potential hazards, safety is paramount in hydrogen and CCUS applications across the value chain.
Hydrogen’s unique properties present several key challenges to operators. Be it the risk of permeation and embrittlement due to the element itself or demanding process conditions such as high pressure, high temperature or cryogenic conditions. Carbon dioxide presents challenges when it comes to pipeline transport in dense phase due to its unique behavior and the risk of phase changes as well as impurities which could cause issues related to pipeline integrity and safety.

Hydrogen pressure measurement with gold-plated membrane
Pressure measurement in hydrogen applications presents a unique challenge due to permeation. In hydrogen gas service, molecules diffuse through the diaphragm surface of the pressure transmitter and form gas bubbles in the fill fluid. Since the pressure cell or diaphragm seal is a closed environment, this additional volume has no means of escape and thin 316L / Alloy C membrane becomes distended resulting in damage.

Reliable temperature measurement in SMR and ATR processes
Steam methane reforming (SMR) is one of the most important and efficient processes for hydrogen production. In reforming reactors, methane is heated with steam to obtain a mixture of hydrogen and carbon monoxide after an endothermic reaction in the presence of a catalyst at high temperature (900 °C) and high pressure. Further process steps in hydrogen production involve a water gas shift reactor and Pressure Swing Absorbers (PSA).
この分野における実績
In autothermal reforming (ATR), oxygen and steam react with hydrocarbons to produce syngas. The process conditions are characterized by maximum operating temperatures between 900°C and 1200°C, strong thermal gradients in two zones filled with high-performance catalysts, and pressure of up to 80 bar.
Continuous monitoring of the operating temperature range is essential to achieve high plant efficiency and safety. By relying on Endress+Hauser temperature measurement devices, you benefit from:
Robust, high-temperature thermocouples guaranteeing long lifetime thanks to innovative thermowell materials with increased wear and chemical resistance for continuous heat supply optimization
Improved flow measurement with Coriolis flowmeters
Hydrogen is the lightest gas that exists and at atmospheric conditions it has a density that is 10 times lower than natural gas. Since hydrogen streams have little mass to propagate sound and often exhibit high gas velocities, velocity-based measurement principles struggle to produce repeatable and accurate flow measurement results.
この分野における実績
Coriolis mass flow meters from Endress+Hauser can help you overcome these challenges:
Coriolis mass flow meters do not use any of the gas properties as part of the measurement principle which makes this technology the preferred choice for hydrogen measurement
Highest measurement sensitivity to achieve the widest mass flow measurement range
Superior zero-point stability, can measure hydrogen at low pressure with the lowest measurement error in the market
Guided wave radar level measurement in CO2 storage tanks
With the deployment of CCUS technologies, large volumes of carbon dioxide are captured from industrial complexes to minimize emissions. CO2 can be transported in different phases and offers unique challenges due to phase changes. CO2 is primarily stored in liquid phase and transported via marine vessels for sequestration/permanent storage. Safety considerations are critical here considering the low temperatures of liquid CO2 and material handling.
この分野における実績
Liquid CO2 level measurement in storage and transportation tanks is challenging due to its low dielectric constant. Endress+Hauser guided wave radar technology offers benefits related to:
Patented end-of-probe evaluation algorithm as well as a coaxial probe enabling stable and precise measurement
The measurement is unaffected by fluctuations in the process density, temperature, or build-up ensuring process reliability
No maintenance and moving parts unlike mechanical instruments guaranteeing safety and availability
Capacitance level measurement for liquid hydrogen tanks
Liquid hydrogen (LH2) level measurement presents a challenging task due to the extreme cryogenic temperatures down to -253°C and operator challenges associated with handling this substance. There are different technologies in Endress+Hauser’s portfolio to measure those low temperatures: DP level measurement with impulse pipes is a classical solution in cryogenic applications, however, servo technology can also do the job as well as Endress+Hauser’s oldest technology: capacitance probes.
この分野における実績
Capacitance technology provides proven in use measurement in LH2 applications. The measurement is independent of the dielectric constant, vapors, temperature, and pressure changes, thus providing safe and reliable level measurement.
Enhanced safety through proven capacitance technology
Special insulation components and separate electronics make sure the cryogenic temperatures do not harm the devices
Proven in use and suitable for use in small and medium stationary tanks
