Moisture analysis – Choose an online hygrometer moisture analyzer

How to choose the right online hygrometer process moisture analyzer for your application? When selecting a gas analyzer for moisture analysis, you may not be sure which one is the best for your requirements or process. Choosing the right moisture analyzer for your specific application goes beyond specifications which don’t show the complete picture. Moisture measurement performance for your process sample or what is necessary for uninterrupted all year operation are just some examples of criteria which can’t be found on the datasheet. Therefore, it’s crucial to understand the functionality and performance of the instrument from a complete process view.

Moisture in short

Moisture in process gas is a contaminant that reduces the thermal conductivity and increases the viscosity of the gas. The presence of moisture indicates that either the system was not purged adequately after the last maintenance cycle or that there is an ambient leak, which can be a very damaging and hazardous condition.

Types of moisture analyzers for MOISTURE ANALYSIS

Quartz Crystal Microbalance (QCM) analysis

Quartz Crystal Microbalance (QCM) for moisture analysis employs a quartz crystal whose oscillation frequency changes in response to mass variations on its surface. When exposed to a gas sample, moisture adsorbs onto the crystal, altering its mass and consequently its oscillation frequency. This frequency shift is directly proportional to the moisture content, allowing for precise and sensitive moisture measurements. QCM is valued for its sensitivity and response.

Chilled mirror analysis

Chilled mirror technology for moisture analysis involves cooling a mirror to a temperature where moisture from a gas sample condenses on its surface. This dew point temperature is precisely measured, providing an accurate indication of the moisture content in the sample. This method is suitable for various applications that require precise humidity control and measurement.

Silicon Oxide sensor technology

Silicon Oxide sensor technology for moisture analysis utilizes a sensitive layer of silicon oxide to detect water vapor. When water molecules interact with the silicon oxide surface, they cause a measurable change in the sensor’s electrical properties, such as capacitance or resistance. This change is directly correlated to the amount of moisture present, providing accurate and reliable moisture analysis in various applications, from industrial processes to environmental monitoring. This technology is prized for its sensitivity, stability, and rapid response to changes in moisture levels, making it suitable for a wide range of applications where accurate moisture detection is critical.

Range of moisture measurement applications

Transmission Pipelines

Gas is transported from the processing plant to underground storage sites, industrial users and city gate metering stations via a large network of pipelines. As the gas travels along the pipeline, it passes through metering points where it is sold from one party to another – this is the custody transfer point. Understanding the gas quality at custody transfer points is essential.

Dehydration

The dehydration process removes water vapor in natural gas. Several different methodologies are used to accomplish this, including compression, phase separation, absorption and adsorption. Tri-ethylene glycol contactors and molecular sieve dryers are two of the more common dehydration methods for gases. Moisture measurement is critical to optimize the drying process and ensure that the gas is dried to the required specification. Analysis is typically performed at the outlet of the drying process.

Sweetening

Sweetening is the process whereby hydrogen sulfide (H2S) and carbon dioxide (CO2) are removed from the natural gas. Both H2S and CO2 promote corrosion through the formation of acids in the presence of water and can cause stress cracking in the pipelines. 

Landfill Gas

Landfill gas is generated from the decomposition process of organic materials contained in a landfill. Similar to conventional natural gas, landfill gas can be transmitted in a pipeline network for use in transportation, power generation, or at industrial end users. Unlike conventional natural gas, landfill gas typically contains a lower concentration of methane and higher concentrations of impurities, such as carbon dioxide (CO2). Landfill gas must be treated to remove unwanted impurities, such as CO2, hydrogen sulfide (H2S), or water vapor (H2O), prior to injection into a pipeline or transmission to an end use.

Underground storage

Just like transmission measurements, impurities in the captured CO2 need to be measured.  Although levels of H2S, methane, and carbon monoxide are not likely to significantly change during storage, moisture levels can. Pipeline managers need to understand any changes in the moisture levels in order to properly manage it.

Gas purification

Most industrial gases are produced to meet a specified purity. This requires accurate monitoring of any contaminants such as moisture, carbon dioxide, carbon monoxide, hydrogen, oxygen, or hydrocarbons, during the production process to ensure the necessary quality is met. Industrial gas suppliers demand accuracy to certify product quality. Fast, precise and reliable analysis of the gas is carried out to ensure impurities remain within specified, very low limits.

Hydrogen recycle gas

Proper moisture balance in feedstocks and hydrogen recycle streams must be maintained to optimize product yield and catalyst life. Accurate and rapid results are required despite wide variations in moisture content.

Quality

The aim of gas purification is to ensure the required level of product quality. Monitoring the trace contamination from moisture and other compounds using a range of technologies helps determine the final quality.
