Abstract

A technique to cool and reheat a sampling gas to dehumidify the gas is described herein. The technique reduces related humidity of the sampling gas. The technique utilizes a vortex tube and two heat exchangers for different temperature gas flow. One temperature gas flow is in a hot side and another gas flow is in a cold side. The gas is introduced to the cold side of a first heat exchanger to cool the sampling gas. Afterwards, gas is introduced to the hot side of a second heat exchanger to reheat the sampling gas.

APPARATUS AND METHOD TO DEHUMIDIFY THE GAS

 

BRIEF ABSTRACT

A technique to cool and reheat a sampling gas to dehumidify the gas is described herein. The technique reduces related humidity of the sampling gas. The technique utilizes a vortex tube and two heat exchangers for different temperature gas flow. One temperature gas flow is in a hot side and another gas flow is in a cold side. The gas is introduced to the cold side of a first heat exchanger to cool the sampling gas. Afterwards, gas is introduced to the hot side of a second heat exchanger to reheat the sampling gas.

DETAILED DESCRIPTION

            A sampling gas contains moisture due to which related humidity in the sampling gas is quite high. With high humidity, condensation easily occurs on hydrogen probe tip. When the condensation results in water becoming stuck in a membrane in the probe tip, the hydrogen probe does not function properly. Therefore there is need to dehumidify the sampling gas. To dehumidify the sampling gas there are several constraint which include temperature of the sampling gas, explosion proof, and low maintenance among others.

            A conventional technique includes a hydrogen detection sensor for dry sampling gas to utilize a vortex cooler, an inlet filter, liquid block and a membrane dryer to dry the sampling gas.

            Another conventional technique includes a hollow cylindrical heat pipe with vaporizable liquid. The heat pipe includes an evaporating section to absorb heat and boil fluid to vapor phase, and liquid returns back to the lower part of cylinder.

            Another conventional technique includes apparatus to remove oil and water vapor from a compressed gas in which the gas is passed through an oil filter and then a portion is fed into a vortex tube.

            Yet another conventional technique includes a double pass heat exchanger...
