    摘要: A method for maintaining a flammable solvent in a nonflammable environment involves covering the flammable solvent with a nonflammable vapor blanket provided by a nonflammable solvent, such that vapors from the flammable and nonflammable solvents form a nonflammable gaseous mixture in the blanket. Such a method is used in removal of both oil-based and polar contaminants to control the flammability potential of an alcohol solvent. An apparatus for cleaning articles using fluorocarbon and alcohol solvents includes a chamber having a plurality of compartments for containing the solvents and a bounded vapor space. At least one of the compartments contains liquid fluorocarbon and at least one other will contain liquid alcohol. The solvents voltalize into the bounded vapor space to provide a nonflammable vapor blanket over the alcohol-containing compartment. Volatilized alcohol is mixed with the volatilized fluorocarbon to form a nonflammable mixture which is purified and separated, and the recovered fluorocarbon can be reused in subsequent cleaning operations.

    摘要: A method of stabilizing chlorofluorocarbon compositions thereby is provided. The stabilized composition comprises a chlorofluorocarbon and a sufficient amount of an epoxidized, generally high molecular weight stabilizer having an oxirane content sufficient to effectively stabilize the chlorofluorocarbon. The stabilizer is preferably an epoxidized oil having a molecular weight in the range of about 300 to about 1,500 and an oxirane content of at least about 4%. The method includes the step of adding a sufficient amount of such a stabilizer to the chloroflurocarbon composition. The chlorofluorocarbon composition typically comprises chlorofluoromethane, chlorofluoroethane, mixtures thereof or a chlorofluorocarbon-alcohol azeotropic solution. Also provided is an improved continuous dialyzer cleaning method utilizing the stabilized chlorofluorocarbon composition.

    摘要: Systems and methods for performing hemodialysis to remove metabolic waste from the blood of a patient are disclosed. The systems and methods preferably comprise at least one blood processing apparatus that receives whole blood from a patient. Cellular blood components are removed from the whole blood by hemofiltration, to provide filtered plasma comprising metabolic waste that is substantially reduced of blood cells. The cellular blood components may be returned to the patient. The filtered plasma comprising waste may be removed from the blood processing apparatus through a waste path for further processing in a separate apparatus, or in the same apparatus in a second stage processing procedure to remove metabolic waste components and excess water from the plasma by hemodialysis. At least one of the hemofiltration and hemodialysis processing apparatus comprises a Taylor vortex-enhanced separation apparatus.
