Abstract

THE METHOD OF THE INVENTION FOR LIQUEFYING A NATURAL GAS CONSISTS IN LIQUEFYING AT LEAST A PART OF THIS GAS BY EXPANDING IT WITH MECHANICAL ENERGY, WHEREBY DURING THIS EXPANSION THE GAS CHANGES FROM THE DENSE PHASE TO A LIQUID PHASE WITHOUT UNDERGOING A PHASE TRANSITION.THE METHOD COMPRISE AT LEAST THE FOLLOWING TWO STEPS: A) THE NATURAL GAS MADE UP OF SEVERAL CONSTITUENTS IS COOLED AT A PRESSURE THAT IS THAT LEAAST GREATER THAN OR EQUAL TO THE CRITICAL PRESSURE VALUE OF METHANE AND AT A TEMPERATURE WHICH IS SUCH THAT THE GAS WILL BE IN THE DENSE PHASE AT THE END OF COOLING,B) AT LEAST A FRACTION OF THIS PHASE OBTAINED FROM STEP A) IS EXPANDED AND LIQUEFIED THROUGH A DEVICE DESIGNED TO REDUCE THE PRESSURE OF THE GAS BY EXPANSION WITH MECHANICAL ENERGY, THE CHANGE OF STATE FROM THE DENSE PHASE TO A STATE OF LIQUID SUBSTANTIALLY OCCURING WITHOUT A PHASE TRANSITION.
