1084 results about "Dew" patented technology

Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation. As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that at which it can evaporate, resulting in the formation of water droplets.

Compression stripping of flue gas with energy recovery

A method of remediating and recovering energy from combustion products from a fossil fuel power plant having at least one fossil fuel combustion chamber, at least one compressor, at least one turbine, at least one heat exchanger and a source of oxygen. Combustion products including non-condensable gases such as oxygen and nitrogen and condensable vapors such as water vapor and acid gases such as SOX and NOX and CO2 and pollutants are produced and energy is recovered during the remediation which recycles combustion products and adds oxygen to support combustion. The temperature and / or pressure of the combustion products are changed by cooling through heat exchange with thermodynamic working fluids in the power generation cycle and / or compressing and / or heating and / or expanding the combustion products to a temperature / pressure combination below the dew point of at least some of the condensable vapors to condense liquid having some acid gases dissolved and / or entrained and / or directly condense acid gas vapors from the combustion products and to entrain and / or dissolve some of the pollutants while recovering sensible and / or latent heat from the combustion products through heat exchange between the combustion products and thermodynamic working fluids and / or cooling fluids used in the power generating cycle. Then the CO2, SO2, and H2O poor and oxygen enriched remediation stream is sent to an exhaust and / or an air separation unit and / or a turbine.

Portable, potable water recovery and dispensing apparatus

A portable, potable-water generator for producing high-purity liquid water by condensation of water vapor from ambient air. The generator (125) employs an air filter (119) to remove particulates and aerosols from the incoming air. An enclosed heat absorber cools the filtered air to its dew point and collects droplets of condensate into a condensate collector (5). Before discharge, the collected dew is treated in a bacteriostat loop to destroy adventitious living organisms and to filter out undesirable and dangerous contaminants. A recirculation loop provides the ability to recirculate stored condensate, including during periods of inactivity. Further, quick disconnect fittings (55b) and variable length flexible tubing allows use of the invention to serve remote dispensers and / or appliances and allow use of municipal water treated through the apparatus in low condensate situations.

Method and apparatus for determining an optimal pumping rate based on a downhole dew point pressure determination

The present invention provides a down hole spectrometer for determination of dew point pressure to determine an associated optimal pumping rate during sampling to avoid precipitation of asphaltenes in a formation sample. A sample is captured at formation pressure in a controlled volume. The pressure in the controlled volume is reduced. Initially the formation fluid sample appears dark and allows less light energy to pass through a sample under test. The sample under test, however, becomes lighter and allows more light energy to pass through the sample as the pressure is reduced and the formation fluid sample becomes thinner or less dense under the reduced pressure. At the dew point pressure, however, the sample begins to darken and allows less light energy to pass through it as apshaltenes begin to precipitate out of the sample. Thus, the dew point is that pressure at which peak light energy passes through the sample. The dew point pressure is plugged into an equation to determine the optimum pumping rate for a known mobility, during sampling to avoid dropping the pressure down to the dew point pressure to avoid asphaltene precipitation or dew forming in the sample. The bubble point can be plugged into an equation to determine the optimum pumping rate for a known mobility, during sampling to avoid dropping the pressure down to the bubble point pressure to avoid bubbles forming in the sample.

Vehicle control device and method of controlling vehicle

In a hybrid vehicle, an ECU executes drive control of an EHC. For the control, the ECU first executes low-voltage drive in which a drive voltage is reduced to 50 V when an energization request of the EHC is made. Then, based on a resistance value of the EHC, the ECU detects whether or not electric leakage is caused by dew formation of condensed water in the EHC. Consequently, if the electric leakage is detected, the energization of the EHC is inhibited. If electric leakage is not detected, the drive voltage Vd is increased to 200 V for normal drive to heat a catalyst by the EHC.
