How TÜV SÜD are serving to to handle technical challenges
As a part of the worldwide drive to scale back greenhouse gasoline emissions there is a urgent want to move towards clear fuels for power. The use of hydrogen as a substitute for pure fuel in the gas grid networks is seen as a major contributor to assembly this objective. Manufacturers, fuel community corporations and governments are working closely collectively to handle a selection of technical challenges earlier than this alteration can turn out to be a actuality. TÜV SÜD National Engineering Laboratory is a world-leading centre for move metrology analysis and improvement. To assist handle those challenges, it’s building a variety of hydrogen tests amenities. These services include the Hydrogen Domestic Gas Metering Test Facility, developed for testing smaller scale gear at lower pressures, coupled with the event of a gasoline main circulate commonplace test facility, which supplies decrease measurement uncertainty and higher choices for fundamental metrology research, as nicely as higher hydrogen move fee and pressure ranges. เกจแรงดัน describes the prevailing hydrogen test facilities and those underneath improvement at TÜV SÜD National Engineering Laboratory.
The hydrogen domestic gas metering test facility has been developed to provide a platform to investigate not only the efficiency of circulate meters, but in addition for different gear associated to hydrogen operation, including control valves, PRVs, regulators, heat exchangers, etc. in a hydrogen service. The take a look at facility has been developed for small scale applications and can ship a range of gasoline flows together with hydrogen, methane, nitrogen or mixtures of hydrogen and methane. The check facility is able to delivering as much as 38 Sm3/h of hydrogen to the system beneath test at line pressures up to 1500 mbar, with temperatures starting from -25 to fifty five ˚C. It can operate with line sizes starting from 5 to 20 mm. Construction was accomplished final year and it’s now out there to be used by business for product development or circulate testing of hydrogen gear and valves.
The swap over from natural fuel to hydrogen might take place in a staged method involving hydrogen/natural fuel blends or direct change to pure hydrogen. Manufacturers can carry out a whole evaluation of equipment performance across a spread of hydrogen to natural gas compositions from 0 to one hundred pc hydrogen.
The hydrogen domestic fuel metering test facility has been specifically designed for low-pressure hydrogen functions and TÜV SÜD recognised that there was additionally a necessity for a larger flow, greater stress test facility. TÜV SÜD has undertaken a challenge beneath the BEIS-funded Flow Programme to ascertain a Gas Primary Flow Standard Test Facility. Initially, it will function with hydrogen, nitrogen and methane however with a view to be prolonged to carbon dioxide. The facility is currently in the detailed design stage and the plan is to have an working envelope of up to a hundred Sm3/hr of fuel with the ability to operate as a lot as a hundred and twenty bar.
