Abstract
Large quantities of CO.sub.2 snow are provided by a system and method which utilizes two reservoirs which maintain at least about 4500 pounds of CO.sub.2 at about its triple point, a substantial portion of which contains solid CO.sub.2. A first such reservoir subcools high pressure liquid CO.sub.2 flowing therethrough and permits efficient production of CO.sub.2 snow. A second such reservoir assists in cooling and condensing CO.sub.2 vapor recirculating through the system, as well as in efficiently obtaining CO.sub.2 being delivered to the system from an outside source.
