Factors to Consider When Choosing a Natural Gas Moisture Sulfur Analyzer Indonesia

Accuracy

Electrochemical sensors, quartz crystal sensors, and electrolytic sensors have an important similarity; they all interact with the gases, where moisture is absorbed into the treated surface and several changes in physical properties occur that can be measured appropriately. Due to the gradual decrease in the effectiveness of sensor surfaces, it drifts over time.

Recent developments in Spectroscopy have made it possible to send a beam of light through a natural gas sensor which is then analyzed to determine the absorbance of certain wavelengths of light. This technique is not susceptible to contamination and is not sensitive to flow, because the sensor does not touch the gas flow.

Speed

Some processes occur very slowly and the amount of moisture in natural gas does not change rapidly. In other cases, the so-called "slug" or "snail" spike may occur with very harmful effects. For example, if something goes wrong at the dehydration plant, or if a wet gas source is inserted upstream, the water content can jump.

With laser-based natural gas analysis, there is no time required for absorption. Readings are provided every second, with the only delay is the time it takes to get the sample to the analyzer. This eliminates delays in reading time.

Disturbance

Interference occurs when a sensor can be fooled by a gas other than the target gas. The surface-based sensor works by allowing moisture molecules to the surface where it can react with the sensitive
sulfur analyzer indonesia layers inside them. But what if other molecules can get into the surface and react?

Laser-based moisture analyzer measures light absorption. Since there are no other components in natural gas absorbing light from the same wavelength, there is no interference. The laser-based analyzer is completely immune to the amount of methanol, amine, glycol, sulfur, or other gases present; just detect water molecules!

Maintenance

Electromechanical and electrolytic sensors require regular restoration or replacement of sensor heads. Some sensor heads have to keep at hand to prevent long downtime. Quartz crystal analyzers require the replacement of sensor heads and the replacement of desiccant tubes and expensive permeations that require special downtime and training.

The laser-based natural gas analyzer consists of an electronic component (solid state) that is not in contact with natural gas and has no moving parts. This tool is so powerful and simple that it hardly requires maintenance.

Underline

For the total cost of ownership, the initial investment plus the cost of maintaining the analyzer for some time should be added together.

The first year of ownership shows the least cost electrochemical or electrolytic sensors, but by the end of the year two costs will be equal to the number of laser-based systems. After 5 years, the cumulative cost can be twice as high or more
