摘要： A process for recovering waste heat which comprises: (a) passing a liquid phase working fluid through a heat exchanger in communication with a process which produces the waste heat; (b) removing a vapor phase working fluid from the heat exchanger; (c) passing the vapor phase working fluid to an expander, wherein the waste heat is converted into mechanical energy; and (d) passing the vapor phase working fluid from the expander to a condenser, wherein the vapor phase working fluid is condensed to the liquid phase working fluid. The preferred working fluid is an organic Rankine cycle system working fluid comprising compounds having the following general structure: where x, y, z, and m are each selected from the group consisting of: fluorine, hydrogen, Rf, and R, wherein R and Rf are each an alkyl, aryl, or alkylaryl of 1 to 6 carbon atoms, and wherein Rf is partially or fully fluorinated.

摘要： A method of detecting a leakage of a chemical from a closed system into the environment and/or revealing the location of the leakage is provided. The method includes the steps of: placing a test strip in close proximity of or in direct contact with a suspected leak in the closed system, the test strip including a support material and a color forming composition disposed on the support material, the color forming composition including a dye precursor encapsulated in a microcapsule, a developer and optionally a filler; and detecting development of a color on the test strip in response to contact of the microcapsule with the chemical thereby indicating the presence of and/or the revealing the location of the leak.
