Abstract: The invention comprises a system for supplying carbon dioxide liquids while maintaining a desirable pressure in a liquid carbon dioxide storage vessel. In an exemplary embodiment, an improved vaporizer is deployed in a downstream line from the storage vessel. The vaporizer converts a portion of the withdrawn liquid carbon dioxide into replacement carbon dioxide vapor using heat from steam or electricity supplied by the facility. This replacement carbon dioxide vapor is returned to the storage vessel to maintain the desired internal tank pressure as liquified carbon dioxide is withdrawn. The vaporizer includes an elongated cylindrical steel shell with spaced apart ends. Each end has a steel end cap that is welded to the body. Either end cap may be removed to service the vaporizer. The vaporizer body is penetrated by three ports, a steam inlet, a liquid carbon dioxide inlet and a carbon dioxide vapor outlet. The steam inlet accepts steam from the facility while the inlet accepts liquid carbon dioxide and the outlet emits carbon dioxide vapors. Other types of heating mediums such as air or hot water, may be used as well. The vaporizer body houses a tubing unit for vaporizing the liquid carbon dioxide. The tubing unit has an inlet, outlet and vaporization section. The vaporization section tubing is preferably formed from copper while the inlet and outlet pipes are preferably steel. The tubing unit includes several individual coils wound in a series of loops extending between the inlet and outlet pipes respectfully. When servicing the vaporizer, the technician may remove an end cap by cutting it off with a welding torch or another suitable method. The tubing unit may then be freed by uncoupling the inlet unions adjacent the inlet ports. The entire tubing unit may then be removed from the body.

Abstract translation: 本发明包括一种用于在液体二氧化碳储存容器中保持理想压力的同时供应二氧化碳液体的系统。 在示例性实施例中，改进的蒸发器部署在来自存储容器的下游管线中。 蒸发器使用来自设备供应的蒸汽或电力的热量将一部分抽出的液体二氧化碳转化成替代二氧化碳蒸气。 当液化的二氧化碳被排出时，该替换的二氧化碳蒸汽返回到储存容器中以保持所需的内部罐压力。 蒸发器包括具有间隔开的端部的细长圆柱形钢壳。 每个端部都有一个焊接到车身上的钢制端盖。 任何一个端盖可能被移除以服务蒸发器。 蒸发器主体由三个端口，蒸汽入口，液体二氧化碳入口和二氧化碳蒸气出口穿透。 蒸汽入口接受来自设施的蒸汽，而入口接受液体二氧化碳，出口排出二氧化碳蒸汽。 也可以使用其他类型的加热介质，例如空气或热水。 蒸发器主体容纳用于蒸发液体二氧化碳的管道单元。 管道单元具有入口，出口和蒸发部分。 蒸发部管优选由铜形成，而入口管和出口管优选为钢。 管道单元包括几个单独的线圈，其缠绕在一系列循环中，该系列在入口管和出口管之间相互延伸。 在维修蒸发器时，技术人员可以用焊炬或其他合适的方法切割端盖。 然后可以通过使靠近入口端口的入口接头脱离联接来释放管道单元。 然后可以将整个管道单元从身体移除。
