A system for providing industrial gas to a usenpoint in relatively small quantities that wouldnotherwise require the use of high pressure gasncylinders, wherein industrial gas (4) is generated (30) from anfeed (1), liquefied using refrigeration generated by anrefrigeration system (34), and stored in a storage vessel (33)nprior to provision to the use point (7). The preferrednrefrigeration system is a pulse tube system powered byngas associated with the industrial gas generationnsystem. |
