Description

WO 2011/151549 PCT/FR2011/051030 Method and Apparatus for Producing Liquid Carbon Dioxide The present invention relates to a method and an 5 apparatus for producing a carbon dioxide-rich liquid. It applies in particular to gas separation and purification processes based on the principle of physical absorption, which require operation at temperatures below 012C, such as the Rectisol@ or the 10 Selexol@ process, in which the carbon dioxide must be produced either in liquid form, or in compressed form for purposes such as sequestration, EOR (Enhanced Oil Recovery), or any other application dedicated to reducing carbon dioxide emissions. 15 In a gas separation and purification unit based on the physical absorption principle which requires operation at temperatures below 01C, like the Rectisol® or the Selexol@ process, it is necessary to supply large refrigeration loads for the process to operate 20 efficiently. The refrigeration duty is commonly supplied by refrigerating units operating on fluids external to the process, such as ammonia or propylene, for example. In the context of reducing carbon dioxide 25 emissions by precombustion processes, the separated carbon dioxide must be produced either in liquid form for road, river or maritime transport, or in compressed form for pipeline transport. These processes also use a compressor operating with the fluid to be liquefied 30 (carbon dioxide) to provide the heat balance required for producing carbon dioxide in liquid or compressed form. Figure 1 shows an apparatus of the prior art. A gas separation and purification unit of the Rectisol@ 35 type 10 separates a gas to be treated containing carbon dioxide 1 to produce a purified gas 2 and a carbon dioxide-rich gas. The separation unit 10 is cooled by means of an external refrigerating unit 11 using a WO 2011/151549 - 2 - PCT/FR2011/051030 refrigerant 3, 3'. The carbon dioxide is liquefied in a liquefier 12 to produce liquid carbon dioxide 5. According to an object of the invention, a method is provided for producing a carbon dioxide-rich liquid 5 as end product, in which: i) a feed gas comprising carbon dioxide is separated by physical washing with a solvent at a temperature below 0"C ii) the solvent required for the physical 10 washing of step i) is cooled iii) a carbon dioxide-rich gas is produced by separation according to step i), the said gas is compressed and liquefied iv) the carbon dioxide-rich gas is cooled 15 upstream and/or downstream of the compression operation of step iii) and v) a single refrigeration cycle, using carbon dioxide as refrigerant, supplies the refrigeration for the cooling operation of step iv) and 20 for a cooling operation required in step i), at least part of the carbon dioxide used as refrigerant issuing from the liquefaction operation of step iii). According to other optional aspects: - the same refrigeration cycle serves to cool the 25 carbon dioxide-rich gas upstream and/or downstream of the compression operation; - the same refrigeration cycle serves to cool the solvent upstream of the washing operation; - the solvent is methanol; 30 - the carbon dioxide-rich gas is liquefied after the compression operation of step iii). According to a further object of the invention, an apparatus is provided for producing a carbon dioxide rich liquid as end product, comprising 35 i) a separation unit comprising a column for physical washing with a solvent and means for cooling a fluid of the separation unit, WO 2011/151549 - 3 - PCT/FR2011/051030 ii) a unit for compressing and liquefying a carbon dioxide-rich gas derived from the separation unit in order to produce liquid carbon dioxide as end product, the compression and liquefaction unit 5 comprising means for cooling the gas upstream and/or downstream of the compression operation, iii) a single refrigeration cycle using carbon dioxide as refrigerant, being suitable for supplying refrigeration to the means for cooling the 10 fluid of the separation unit and to the means for cooling the carbon dioxide-rich gas upstream and/or downstream of the compression operation and iv) means for sending part of the liquid carbon dioxide from the separation and liquefaction 15 unit to the refrigeration cycle. Optionally, the apparatus comprises means for cooling the solvent upstream of the washing operation by means of the refrigeration cycle. The invention consists in using a single 20 refrigeration cycle supplying the refrigeration for cooling required for the gas separation and purification unit, for example of the Rectisol@ type, in particular for cooling the washing solvent, and for cooling a stream of carbon dioxide-rich gas issuing 25 from the gas separation and purification unit. Such a method serves to reduce the investment by combining the functions. The invention is described in greater detail with reference to Figure 2. A unit for separating and purifying gas by 30 physical washing with a solvent at a temperature below 0 2 C of the Rectisol@ type 10 separates a gas to be treated 1 containing carbon dioxide to produce a purified gas 2 and a carbon dioxide-rich gas 4. The separation unit 10 is cooled by means of a cycle using 35 a refrigerant 103, 103' issuing from a unit 12 for treating the carbon dioxide-rich gas 4. The carbon dioxide treatment unit 12 is a compression unit C followed by a liquefaction unit L producing carbon WO 2011/151549 - 4 - PCT/FR2011/051030 dioxide in liquid form 5. The carbon dioxide-rich gas compressed by the compression unit C is liquefied by the unit L to produce the end product 5. A portion 103 of the liquid formed can cool the compressed stream 5 downstream and/or upstream of the compression unit C by means of the heat exchangers El, E2. In particular, the refrigerant 103 sent to the unit 10 can serve to cool a stream of solvent used in a washing step of the method. 10 The same fluid can serve to cool the carbon dioxide upstream and/or downstream of the compression operation in the unit 12. The fluid is carbon dioxide and issues from the gas 4 treated in the unit 12. 15
