Basic manual dew point measurement devices are commonly used by surveyors when monitoring the dryness of a cargo tank prior to loading a liquid chemical product. Which of the descriptions below is a summary of how the measurement is carried out?
A small quantity of Methanol is placed into the device and dry-ice is progressively added to it to steadily reduce the temperature. A sample of the atmosphere in the tank is continuously drawn through the device, passing over the surface of the Methanol. When the first signs of evaporation are observed (smoke rising from the surface), the temperature of the Methanol is noted. Reference may be required to tables to correct the reading for calculation purposes.
A quantity of Acetone is placed into the device and dry-ice is progressively added to it to steadily reduce the temperature. A sample of the atmosphere in the tank is continuously pumped through the liquid. Bubbles will be seen to reach the surface of the bath until the dew point is reached. When the flow of bubbles ceases, the temperature of the Acetone is noted. Reference may be required to tables to correct the reading for desired parameters.
A small quantity of Acetone is placed into the device and dry-ice is progressively added to it to steadily reduce the temperature. A sample of the atmosphere in the tank is continuously drawn through the device, passing over the polished or mirrored surface of the container. When the first drop of mositure (dew) is observed to form on the polished surface, the temperature of the Acetone bath is noted. Reference may be required to tables to correct the reading for desired parameters.
A small quantity of dry-ice is placed into the device, submerged in deionized water. A sample of the atmosphere in the tank is continuously drawn through the device, passing across a reagent filter. When the dew point is reached, this reagent filter will change colour from white to green, indicating saturation. The temperature of the deionized water is noted at this time and corresponds to the dew point. Reference to correction tables is required to correct the reading for barometric pressure.
