Preface

My interest and experience in cryogenic engineering began in the early 1960s when we set up the first postgraduate training course on “Cryogenics and Its Applications”. At that time, cryogenics meant LOX, LIN, LH2 and LHe. This course was developed to involve industry in the teaching and the hands-on demonstrations, together with a 3-month project in industry for all the students in participating companies. Very soon, we found the project work was taking us into 3-year Ph.D. research programmes on a wide range of interdisciplinary topics, together with expanding into higher temperatures within the world of hydrocarbons, using a purpose-build LNG Safety Laboratory. This expansion was also taking us into the new territory of irreversible thermodynamics and the extraordinary properties of cryogenic liquid mixtures. LNG was one of these mixtures, but not the only one or the first one we met. At that time (1960), LPGs with normal boiling points between −40 and −2 °C were being developed as an industrial fuel by liquefying the gas being flared off at refineries and oil wells. We were soon introduced to the problems of handling LPGs in bulk and surprised to
