摘要:
A counter-flow simultaneous heat and mass exchange device is operated by directing flows of two fluids into a heat and mass exchange device at initial mass flow rates where ideal changes in total enthalpy rates of the two fluids are unequal. At least one of the following state variables in the fluids is measured: temperature, pressure and concentration, which together define the thermodynamic state of the two fluid streams at the points of entry to and exit from the device. The flow rates of the fluids at the points of entry and/or exit to/from the device are measured; and the mass flow rate of at least one of the two fluids is changed such that the ideal change in total enthalpy rates of the two fluids through the device are brought closer to being equal.

An air operated heat exchanger has a plurality of process tubes for process fluid, a plurality of rotating fans to move ambient air along an air stream path past the plurality of process tubes. At least one optical fibre is configured within the one or more air stream paths. At least one light pulse is passed into the at least one optical fibre, and at least one optical signal is detected from the at least one optical fibre in response to the at least one light pulse, to provide at least one signal profile. One or more air temperatures at a plurality of locations along the at least one optical fibre are determined from the at least one signal profile and evaluated against one or more comparison operational conditions.

A method of positively locating the source of leaks in the heat transfer surface area of the plate heat exchanger between separate product and service fluid paths arranged in an intimitate heat exchange relationship is disclosed. The method comprises: circulating a solution through one fluid path of the exchanger, the solution consisting of solvent with appreciable vapor pressure under the chosen test conditions; providing a gas flow across the other fluid path of the exchange surface by means of forced or natural convection; applying a positive pressure differential between solution and gas stream; and detecting visually the location of deposited solutes on or around the other fluid path.

A plate fin fluid processing device includes active layers, where each active layer includes a fin plate sandwiched between parting sheets so that an active fluid space is defined between the parting sheets. The active layers include an outermost active layer having an inlet and an outlet. A contingent layer body is positioned adjacent to the outermost active layer and includes a fin plate positioned between a parting sheet and a cap sheet. The contingent layer body has a fluid space that is sealed with respect to the atmosphere. A pressure monitoring system is in communication with the fluid space of the contingent layer body. An emergency pressure relief device is configured to release a pressure within the fluid space if a preset pressure is exceeded.
