Recompressed transcritical cycle with vaporization in cryogenic or low-temperature applications, and/or with coolant fluid

A liquefied natural gas (LNG) regasification line comprising a regasification section, wherein step 6) of a process for regasifying a fluid and generating electrical energy, said process comprising subjecting a flow of an operating fluid to the following steps:

• 1) pumping, said pumping step comprising a low pressure pumping step 1a) and a high pressure pumping step 1 b),
• 2) heating in a recuperator, thus obtaining a heated flow, said heating step comprising a low temperature heat recovery step 2a) and a high temperature heat recovery step 2b),
• 3) further heating through a high temperature source, thus obtaining a further heated flow,
• 4) expanding in a turbine, with generation of electrical energy, thus obtaining an expanded flow,
• 5) cooling in a heat recuperator by heat exchange, in a step 5a) with the flow of step 2b), and in a step 5b) with the flow of step 2a), thus obtaining a cooled flow, and
• 6) condensing said flow of said operating fluid and regasifying said fluid,
• wherein after the low pressure pumping step, a portion of the flow of said operating fluid to a recompression step, thus obtaining a flow which is combined with the flow of the operating fluid obtained from step 2a),
• is carried out inside said regasification section.
