High plant availability in hydrogen production
Why pressure measurement in the steam reformer operates reliably and easily at Messer Industriegase
Messer produces hydrogen in a steam reformer. The facility has a large number of protection and safety devices where pressure values play an important role. Endress+Hauser measuring devices meet all the challenges of hydrogen production due to the gold-coated membrane among other things. They are reliable and provide user-friendly functions, making work easier for the Messer team.
Benefits
-  High plant availability 
-  Accurate and reliable measurement even in very small pressure ranges 
-  Time savings as the devices are easy to operate 
-  Minimum training required 
-  Extended maintenance intervals 
Customer challenge
Pressure measurement is demanding in the steam reforming process. Requirements include temperatures up to 900 °C during production and pressures up to 200 bar during filling. The pressure in the reformer furnace is often in the millibar range. Hydrogen diffusion poses a difficult challenge. The hydrogen atoms can penetrate the metallic membrane of the oil-filled sensors. Bubbles then form in the fill fluid. This causes a zero point shift and eventually leads to a malfunction.
Our solution
The pressure and differential pressure sensors used in Messer's hydrogen production include the Cerabar PMP71B and Deltabar PMD75B. Endress+Hauser has installed pressure gauges in Messer's steam reformer that meet the special requirements of hydrogen production:
- A 25µ-thick gold coating reliably prevents hydrogen diffusion through the membrane into the pressure cell. 
- The devices monitor themselves automatically without interrupting plant operation. 
- A digital assistant guides users through commissioning, maintenance and SIL proof testing step by step. 
- The Bluetooth connection facilitates convenient access to the device.
