The paper deals with the problem of cold recovery for direct utilization both in the site of regasification facility and far from it.A modular LNG regasification unit is proposed having the regasification capacity of 2 billion standard cubic meters/year of gas. The modular plant is based on use of a Power Cycle working with Ethane or Ethylene which allows operation of cold energy transfer, contained in LNG to be regasified, in a range of temperatures suitable for multipurpose use of cold, reducing regasification process irreversibility. Some electric energy is produced by the Power Cycle, but the own mission of modular unit proposed is addressed to deliver cold suitable for industrial and commercial use in the proper 1 Corresponding Author -E-Mail: dispenza@unipa.it * Viale delle Scienze Parco d'Orleans, Ed. 9, 90128 Palermo, Italy, EU ** Salita Santa Lucia Sopra Contesse, 5, 98126 Messina, Italy, EU ACCEPTED MANUSCRIPT temperature range. The option considers, also, the use of Carbon dioxide as a secondary fluid for transfer of cold from regasification site to far end users. This option seems very attractive due to expected wide future exploitation of LNG regasification in the World.Results of a detailed thermodynamic and economic analysis demonstrate the suitability of the proposal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
