The project of the Martiniquaise Air Liquide Company is to increase its liquid nitrogen storage capacity in order to meet the growing needs of the market. Currently, the SOMAL has a storage capacity of 5500 L and wants to increase to 26000 L. This project requires the installation of a new tank, and equipment necessary for operations. The implementation of a new nitrogen reservoir will also have many positive impacts on the SOMAL’s incentive, namely, better day-to-day production management and therefore limiting the shutdown and restart phases of the production unit, a decrease on electricity consumption. Thus, it should be noted that this project is structured around 3 actions which are: optimisation of the carbon dioxide working stand, the installation of a paint booth and the increase of nitrogen production capacity.
