Résumé :	This engineering project is dedicated to the evaluation of the techno-economic potential of a process of liquefaction of ethylene gas resulting from the boil-off phenomenon. A mathematical model has been presented to evaluate the quantities of ethylene produced by boil-off. The obtained results were validated by experimental measurements carried out on site. The sizing of the recovered ethylene liquefaction plant is performed using the Hysis software. Different aspects, technical and geometrical, related to the equipments that make up this installation have been analyzed. In order to test the profitability of the proposed liquefaction plant, the evaporated ethylene, technical and economical analysis was done. The economic potential of the process has been evaluated for the recovery process with respect to the amount of ethylene recovered. It is demonstrated that the technical feasibility and economic opportunity of the proposed process are promising solutions.
