A method and apparatus for separating a separation component from a gas stream. One exemplary method includes: flowing the gas stream across a process surface of a compliant composite heat transfer wall, wherein: the gas stream has an initial concentration of the separation component, and the gas stream has a gas temperature; flowing a cooling fluid across a cooling surface of the wall, wherein: the cooling fluid has a fluid temperature, and the fluid temperature is less than the gas temperature; and producing an output gas stream, wherein: the output gas stream has an output concentration of the separation component, and the output concentration is less than the initial concentration. Another exemplary method includes separating at least a portion of the separation component from the gas stream by: accumulating the portion proximate the process surface; and delaminating the portion from the process surface with a flow of the gas stream.

A system and method removes thermal decomposition components from biphenol and/or diphenyl oxide heat-transfer fluids. Light, volatile decomposition components including benzene, water, hydrogen and phenol leave the system for vapor recovery, chemical adsorption or thermal decomposition. Dimerized and polymerized heavy components such as biphenyl phenyl ether, terphenyl and related isomers are concentrated and recovered. The system can be a continuous, semi-continuous or batch operation. Solar electric plants employing the system can use solar field fluids and heating to operate the system during generator operation hours. A wash system operating at or near atmospheric pressure concentrates heavy thermal decomposition components while allowing removal of light, volatile decomposition components for separation from the majority of the thermal fluid components. Temperature-controlled condensation of the majority of the thermal fluid components allows collection of the thermal fluid, while allowing light, volatile decomposition components to be removed prior to vent processing.

The wireless communications device may be further configured to display an outside temperature, an outdoor humidity, a water level, an indoor temperature, an indoor humidity, and a dew point. The wireless communications device may be further configured to receive control instructions, and wherein the wireless communications device is further configured to communicate the control instructions to the atmospheric water generator.

Method and apparatus for condensing a majority of the solvent in a process gas stream at low temperatures, e.g., below the freezing point of water, ca. 5 C. The gas stream exiting the condenser step may be further processed in one or more emission control devices, such as a single or multi-step series of concentrator devices, such as zeolite concentrator devices. One or more emission control operations can be carried out downstream of the single or multi-step concentrators. The aforementioned condensing process enables the one or more concentrators to operate in a favorable temperature range for removal of 99% or more of VOC, thereby meeting or exceeding strict environmental regulations.
