The difficulty of measuring the water content in natural gas：
Most of the natural gas components are methane, but pollutants usually exist in one or several states. They may be three glycols, ethanol, natural gas liquids, H2S and various particulate pollutants. What pollutants do they contain depends on the source of natural gas. The pressure range of natural gas may range from 50bar to 100bar. These conditions are all difficult for the operating conditions of the dew point analyzer. In most cases, it is necessary to carry out complex cleaning steps for natural gas, such as washing steps to ensure the normal operation of sensors, which makes the workload of instrument maintenance personnel increase.
The best scheme for water measurement of natural gas：
Nanotechnology: sensor familly dew point analyzer using a nano porous metal oxide film technology patents, both from dry to wet or from wet to dry has fast response, and has high accuracy and high repeatability. Nanotechnology has changed the critical characteristics of the materials, so the familly sensor in -110 ~ +20 ~ C (DP) can be accurate, repeatable and rapid measurement range.
