Compression of Hydrogen can be identified as a
critical component involved in the production, transportation, storage
and utilization of hydrogen. This is because of the fact, that
production of Hydrogen either from methane or from water electrolysis is
done at low pressure, but its usage in almost every industrial process
applications requires higher gas pressures. Another factor that makes
Hydrogen Compression important is that at the time of transportation and
storage, higher pressure reduces the size of the cylinders, as well as
the space required for storage of hydrogen.The compressors used for the purpose are solid-state, devices which use heat to compress hydrogen. Hydrogen is usually compressed into high-pressure tanks.
Hydrogen Compressor
The process of a Hydrogen Compressor consists of absorbing hydrogen into a two identical hydride beds in a parallel configuration at low pressure. Each bed is comprised of a certain number of hydrogen heat exchangers, the bed is heated and the hydrogen is released from the alloy at high pressure. The beds are alternately heated and cooled which ultimately results in release of the hydrogen. The cool and hot fluid streams are periodically switched between these to ensure that one bed is always absorbing inlet hydrogen while the second bed is releasing high pressure hydrogen.
Various features of a high quality Hydrogen Compressor are :-
- These compressors consists of pistons and cylinders that are oil &
lubrication free, which provides protection the process gas from oil
contamination.
- Their intensifiers are perfect for high pressures, slow operating
speeds and loads.
- A quality Hydrogen Compressor comes with a simple arrangement and
a piston which is specifically designed to simplify maintenance.
- The pressure of the gas helps at the time of compression by
intensifying the strokes, thus, resulting in increasing of the
overall efficiency.
- They does not require inlet-pressure regulators.
