Abstract: A system and method for preparation of meat flavorants, and flavorants, having increased flavor and aromatic intensity and which more closely resemble the natural flavor and aroma of cooked meat. Preheated edible, food grade oils and fats are exposed to temperatures between 290° C. and 475° C. under vacuum, in the presence of oxygen. The developing flavor vapors are immediately and completely removed from the heated oils and fats. The mixture of air-purge/flavor-vapor is immediately carried away from the heat transfer surface of the edible oil or fat. An evaporator, preferably a spinning disc, spinning band or thin film evaporator, without a condenser is used as process equipment. The air-purged flavor-vapors are diffused and absorbed in an absorption device into suitable food-grade liquids.

Abstract: An exemplary water purification system has a base and a cover that is coupled (e.g., heat sealed) to the base to form a chamber. Raw water, such as seawater or polluted water, is inserted into the base. The raw water evaporates and condenses on an inner surface of the cover, which is inclined to cause the condensed water to flow to a collection channel so that potable water may be drawn from such channel. The base and cover are formed of a lightweight, flexible material to allow the system to be collapsed for easy transport. In addition, the base and cover are supported by a collapsible frame. Accordingly, the system can be easily packaged and shipped at a relatively low cost.

Abstract: Disclosed herein is a process and a plant for recovering ammonia from a mixture including ammonia, acid gas containing H2S and/or CO2 and low-boiling water-soluble organic components. To avoid an enrichment of volatile organic compounds in the acid gas absorber, a partial stream of the liquid phase is withdrawn from an acid gas absorber and processed such that gaseous ammonia with a reduced content of volatile organic components is obtained, which is recirculated into the acid gas absorber.

Abstract: A system and method for removing water from a liquid desiccant such as a glycol used to dry cooled air in order to restore the desiccant to a purity up to around 97% in a closed continuous flow process. Liquid desiccant can be sprayed into cooled air in a conditioner where it gains moisture. The wet or gained desiccant can be optionally preheated in an economizing heat exchanger and then routed into a concentrator. Desiccant pure to around 97% can be removed from the concentrator, passed through an economizing heat exchanger to provide the preheating and returned to the conditioner holding area. The concentrator can be heated by steam or other means such as natural gas to boil the wet desiccant causing mixed vapor to enter a vertical distillation column where most of the glycol condenses out on the column packing or plates and returns to the concentrator.

Abstract: A device for delivering purified water from a reservoir of salt water including a vapor tube supported concentrically inside a barrier tube The vapor tube has apertures that provide a passage of purified condensate from interior of the purified waste to the space between the space between the outside of the vapor tube and the inside of the barrier tube. A pump between the reservoir of salt water and the interior of the vapor tube generates a pressure differential that forces water vapor from the surface of salt water to the inside of the vapor tube. Condensate inside the vapor tube flows as fresh water to outside the vapor tube.

Abstract: The invention provides a means for reducing the energy consumed by thermally activated separation processes such as fractional distillation. This is done by recovering at least part of the reject heat from such processes and upgrading it for recycle back to input heat. The upgrading is accomplished by another low temperature source of heat which may also be the separation process reject heat. A simple and reliable heat pump using the reverse absorption principle is incorporated in the separation process to accomplish this upgrading.
