Abstract: An offshore assembly to operate a facility, in particular an underwater oil and gas production facility. The offshore assembly has: a semi-submersible support structure arranged in a body of water and having at least one tubular portion; a wind turbine to generate electricity and equipped with a tower, a nacelle and a blade assembly. The offshore assembly also has at least one back-up power source mounted on the semi-submersible support structure to generate electricity. A plurality of compartments are stacked on top of each other within the tubular portion. Each of the compartments is dedicated to housing respective equipment to perform respective functions, and a cooling and ventilation system cools and ventilates the plurality of compartments.

Abstract: A process for liquefying and simultaneously purifying natural gas from acidic compounds is provided. The process involves pre-cooling a natural gas flow in a cryogenic exchanger, pre-treating the pre-cooled natural gas flow inside a pre-treatment unit and obtaining a purified flow, heat recovering and obtaining a higher temperature flow, compressing the higher temperature flow and obtaining a first compressed recirculation flow, cooling the first compressed recirculation flow and obtaining a compressed and cooled flow, and separating from the compressed and cooled flow a recirculation flow portion of natural gas. One or more cooling steps are carried out by a flow of nitrogen circulating inside a closed nitrogen refrigeration cycle.

Abstract: A process for regasifying a fluid and producing electrical energy includes subjecting a working fluid to 1) high-pressure pumping, 2) heating in a recovery unit to obtain a heated flow, the heating step comprising a low-temperature heat recovery step 2a) and a high-temperature heat recovery step 2b), 3) further heating to obtain a further heated flow, 4) expanding in a turbine, with production of electrical energy, to obtain an expanded flow, 5) cooling in a recovery unit by heat exchange, in a step 5a) with the flow of step 2b) and in a step 5b) with the flow of step 2a) to obtain a cooled flow, 6) expanding with production of mechanical energy, and 7) condensing the flow of working fluid. After step 5), a portion of the flow of working fluid is not subjected to step 6) and is subjected to a recompressing step.

Abstract: A process for regasifying a fluid and generating electrical energy includes subjecting an operating fluid to 1) pumping, the pumping step including a low pressure pumping step 1a) and a high pressure pumping step 1b), 2) heating in a recuperator to obtain a heated flow, the heating step including a low temperature heat recovery step 2a) and a high temperature heat recovery step 2b), 3) further heating through a high temperature source to obtain a further heated flow, 4) expanding in a turbine, with generation of electrical energy to obtain an expanded flow, 5) cooling by heat exchange to obtain a cooled flow, and 6) condensing the flow of the operating fluid and regasifying the fluid. After low pressure pumping, a portion of the flow of the operating fluid is subjected to recompression to obtain a flow combined with the flow of the operating fluid obtained from step 2a).

Abstract: A method for stripping CO2 from a biocatalyst-containing CO2-rich absorption solution to produce a biocatalyst-containing CO2-lean absorption solution and a CO2-rich gas is provided. The method includes generating a stripping gas from a portion of the biocatalyst-containing CO2-lean absorption solution in a stripping gas generation unit, and contacting the biocatalyst-containing CO2-rich absorption solution with the stripping gas in a gas-liquid contactor to produce the CO2-lean absorption solution and the CO2-rich gas.
