Abstract: Provided is a machine unit layout system that simplifies the layout of a compressor unit and an expander unit and is extremely effective in terms of not only the reliability of the entire machine but also maintainability. Two separate compressors, a low-pressure-side compressor and a high-pressure-side compressor (11A, 11b), are disposed on either side of a steam turbine (10). Two separate expanders, a low-pressure-side expander and a high-pressure-side expander (12A, 12B), are disposed outside the low-pressure-side and high-pressure-side compressors (11A, 11b). The steam turbine (10), the low-pressure-side and high-pressure-side compressors (11A, 11b), and the low-pressure-side and high-pressure-side expanders (12A, 12B) are coupled by rotor shafts comprising a single shaft. The torque distribution between rotator shafts is optimized.

Abstract: This invention relates to the separation of components from a gas mixture. Aspects of the invention relate to the separation of components, for example carbon dioxide (CO2) and/or hydrogen sulphide (H2S) from, for example, acid gas, for example natural gas, syngas or process gas although features of the invention may be applied to other source gases. Such a process is sometimes referred to as acid gas removal (AGR). In examples described herein, the source gas mixture contains CO2 and/or H2S in addition to other components and in some examples, the CO2 and/or H2S components of the gas are referred to as acid gas components. In examples of the invention, some or all of the acid gas component is removed using a solvent absorption method; some examples described use a chemical absorption system (for example including N-Methyl diethanolamine (MDEA)), and others use a physical solvent (for example based on methanol (MeOH)).

The control unit measures a closed circuit voltage and a charging current during charging, and a first closed circuit voltage after a first waiting time and a second closed circuit voltage after a second waiting time. The second waiting time is longer than the first waiting time.

Abstract: A method is described for use in the separation of carbon dioxide from a gas mixture comprising carbon dioxide. The method includes the steps of: (i) compressing and cooling the gas mixture using a compressor to form a two-phase mixture including liquid carbon dioxide (ii) separating a liquid carbon dioxide stream from the two-phase mixture; and (iii) recirculating at least a part of the liquid carbon dioxide stream and introducing the recirculated liquid stream into a process stream by recirculating separated liquid CO2 into an upstream process stream, cooling of the process stream can be obtained. By using the liquid stream, additional cooling is possible as cooling is affected by the evaporation of the liquid CO2. Thus the recirculated liquid can be used to reduce the temperature of the process stream.
