摘要:
A manufactured dry ice product containing ozone entrapped or absorbed on said dry ice. The dry ice product can be used to chill and preserve food products and provides the added benefit of ozonation of the food product to kill bacteria. Novel processes for ozonating liquid and solid CO2 are provided.

摘要:
The invention provides a system for unloading liquified gases from rail cars or other transport vehicles by using an energy buffer system which allows the shifting of electric demand to off-peak hours when electric power rates are lower. The system employs a buffer tank containing solidified gas to withdraw vapor remaining in the rail car after the liquified gas has been removed. The invention relies on the fact that the liquified gas which is to be unloaded has a triple point pressure that is low enough to allow recovery of the majority of the residual vapor in the rail car. The system allows the use of a smaller refrigeration unit operating at a constant load over a long period of time, in place of a larger refrigeration unit. The system also provides an additional advantage of extracting vapor from a rail car at a faster rate than the rate which is possible with a typical compressor.

A blower is used to induce a flow of air through a porous container of solid carbon dioxide and the resulting stream of mixed air and gaseous carbon dioxide is mixed with the ambient atmosphere in an enclosure for euthanization of a large number of non-human animals in an enclosure.

摘要:
A process for removing lubricant, hydrocarbons and mixtures thereof from a vapor compression mechanical refrigeration system by using carbon dioxide as a solvent is disclosed. The process is carried out using supercritical, liquified or gaseous carbon dioxide and removes lubricant to a level below about 5% so as to be compatible with environmentally acceptable refrigerants.
