摘要： The present invention provides a food processing system and method for refrigerating articles of food. The food processing system includes at least two cooling stages formed by a cryogenic freezer and a hydrocooler. The cryogenic freezer receives the articles of food and transfers heat from the articles of food to the cryogen so that the articles of food are refrigerated. After the transfer of heat from the articles of food to the cryogen, the cryogen boils off to form cryogenic vapor. The hydrocooler receives the articles of food prior to the cryogenic freezer and transfers heat from the articles of food to supplied cooling water. Such heat transfer reduces the quantity of cryogen required to refrigerate the articles of food. Additionally, an eductor is connected to a pump and to vent line from the cryogenic freezer. The cooling water is pumped through the eductor to suction cryogenic vapor from the cryogenic freezer and to mix the cryogenic vapor and the cooling water prior to reception of the cooling water in the hydrocooler. Such mixing transfers heat from the cooling water to the cryogenic vapor to increase the heat transfer between the articles and the cooling water in the hydrocooler. As a result of such increased heat transfer, the amount of cryogen required in refrigerating the articles is further reduced The eductor and pump combination has general application to the cooling of articles.

摘要： A method for removing contaminants from a natural gas stream such as a biogas/landfill gas stream. The natural gas stream is fed to a first adsorption unit for removal of certain contaminants and then to a second adsorption unit for the removal of additional contaminants. Alternatively, a membrane stage may be employed between the adsorption units. The method utilizes the external purge to enhance pressure swing adsorption working capacity so that the vacuum level required for regeneration is not as high.

摘要： Using a high pressure rotary adsorbent wheel, a high value compressed gas feed can be purified by concentrating the impurity such as water, condensing it out, before final purification. Instead of exhausting gas from the system, the effluent can be put back into the feed at a point prior to condensation of the high value gas feed, and therefore the entire feed is purified without any high value gas feed going into a waste stream.
