Patent ES-8402729-A1 (ES)
Title: Separation of gases
IPC: B01D59/12
Filed: 1981-04-21
Abstract: The invention provides a method of operating a cascade gas separation process and a gas separation cascade (10) useful for uranium refining and employing a carrier gas. The method and cascade of the invention involve arranging relative gas flow rates between at least some modules (12) in the cascade so that the relative proportions of process gas leaving and entering each of said modules are such that there is a substantially constant molar flow rate of gas in each direction along the cascade through said modules. The proportion of carrier gas relative to process gas increased in opposite directions from the feed (14) to the opposite ends (20, 22) of the cascade and the modules through which the constant molar flow rate takes place have substantially the same size, capacity and construction.

Patent ES-8305489-A1 (ES)
Title: Heat exchanger.
IPC: F28D9/04
Filed: 1981-08-17
Abstract: A heat exchanger, especially for the processing of food or pharmaceutical products comprising at least two coaxially superimposed frusto-conical jackets defining an annular space therebetween. Inlet and outlet means for a first fluid are connected to opposite ends of said annular space, and a spacer in the form of a conical helix is freely and releasably disposed in said annular space in contact with the opposite conical surfaces thereof. The spacer and the conical surfaces defining a helical fluid channel leading from the inlet means to the outlet means. Means are provided for releasably attaching the frusto-conical jackets at their large ends and for sealing the large end of said annular space. The first fluid exchanges heat with a second fluid in contact with a surface of one of said jackets contiguous but exterior to said annular space. Preferably, the exchanger comprises three coaxially superimposed frusto-conical jackets defining two adjacent annular spaces, each having a helical spacer therein defining helical fluid channel for two different fluids in heat exchange relationship. The heat exchanger may be readily disassembled for cleaning purposes. Cleaning is facilitated by the removal of the helical spacer and the fact that the conical surfaces of the jackets are smooth. The helical spacer may be changed by a different one having a different pitch, cross section or coiled in the opposite direction in order to change to flow rates and/or velocities and/or residence times and/or direction of flow of the fluids.
