    • A batch process and apparatus (1) for producing a pressurized liquid carbon dioxide stream includes forming a feed stream (11) of carbon dioxide vapor from a liquid carbon dioxide supply (10) by vaporisation or distillation; introducing the carbon dioxide vapor feed stream into at least one purifying filter (13,14); condensing the purified feed stream within a condenser (18) to form an intermediate liquid carbon dioxide stream (24); introducing the intermediate liquid carbon dioxide stream (24) into at least one high-pressure accumulation chamber (30); heating the high pressure accumulation chamber (30) to pressurize the liquid carbon dioxide contained therein to a delivery pressure; delivering a pressurized liquid carbon dioxide stream (43) from the high-pressure accumulation chamber (30); and, discontinuing delivery of the pressurized liquid carbon dioxide stream (43) for replenishing the high pressure accumulation chamber (30).
    • 一种用于生产加压液体二氧化碳流的分批方法和设备(1)包括:通过汽化或蒸馏由液体二氧化碳供应(10)形成二氧化碳蒸气的进料流(11); 将二氧化碳蒸气进料流引入至少一个净化过滤器(13,14)中; 在冷凝器(18)内冷凝纯化的进料流以形成中间液体二氧化碳流(24); 将中间液体二氧化碳流(24)引入至少一个高压积聚室(30)中; 加热所述高压蓄积室(30)以将其中包含的液态二氧化碳加压至输送压力; 从高压储存室(30)输送加压液态二氧化碳流(43); 并且停止输送加压液体二氧化碳流(43)以补充高压储存室(30)。
