Leading gas compressor company Burckhardt Compression (Burckhardt) has been chosen by South Korea’s largest hydrogen (H2) liquefaction plant to supply it with three Process Gas Compressor AP1618 systems for the compression of hydrogen during liquefaction.

As part of the country’s clean energy strategy, the plant is set to produce up to 90 tonnes of liquefied H2 per day by its completion of 2023.

Allowing for higher liquefaction capacity and an increase in atmospheric pressure of the hydrogen up to 58 bar, the supplied compressors will include auxiliaries and will have a shaft power of 6.6 megawatts per compressor.

Ideally suited for such large-scale projects, Burckhardt claims that its piston compressor technology stands for the longest mean time between overhauls.
