Moisture Analyzers for Emission Monitoring

As we become more aware of the environmental impact of industrial operations, governments and regulatory organizations around the world continue to establish increasingly stringent emissions requirements. In order to ensure compliance with the latest emissions standards, most industrial facilities employ emissions monitoring systems with moisture analyzers to observe and modify pollutant concentration in their emissions. Industrial emission monitoring systems are typically engineered in two designs: continuous emission monitoring systems (CEMS) and predictive emission monitoring systems (PEMS).

CEMS provide ongoing monitoring of gases and particles being expelled by an industrial system. They compile and analyze emissions data to ensure that pollution levels fall below regulatory limitations. PEMS uses computerized software to analyze the cause of combustion inefficiency and improve overall processes. PEMS are less expensive than CEMS and easier to configure; however, each system offers unique benefits for different industrial systems and regulations.

Analyzing Process Gases

Moisture analyzers are used in a variety of industrial processes for detection and mitigation of gases and particle pollutants, including:

  • Coal Mining: Methane is a harmful greenhouse gas that is frequently released into the atmosphere during coal mining operations. In order to reduce these methane emissions and comply with environmental regulations, emission monitoring equipment is used to verify methane levels and adjust operations accordingly.
  • Waste Management: Waste incineration performed at landfills can release harmful gases and particles into the air. Moisture analyzers in emission monitoring equipment help to accurately measure potential pollutants in order to ensure optimal filtration operations.
  • Ethanol Refining and Distilling: Harmful greenhouse gases are released during processes for refining and distilling ethanol. To comply with emissions standards, emissions monitoring systems equipped with moisture analyzers offer accurate emissions analyses to facilitate adequate mitigation.

Analyzing Heated Gases

Moisture analyzers are also used in a variety of heated industrial processes, including:

  • Flue Gases: Monitoring gases as they pass through the industrial stack‘s exhaust flue helps to ensure that exhaust systems are operating with optimal efficiency to keep emissions within designated limits.
  • Steam Generators: Steam generators create energy by burning fuel in the presence of oxygen. The nitrogen oxide emissions released by these systems can be significantly reduced through the use of dedicated emissions monitoring equipment.
  • Process Heaters: Process heaters in refineries are increasingly using less expensive fuels that create higher levels of pollution. This makes monitors with moisture analysis especially critical to maintaining appropriate emission levels.
  • Oxygen Furnaces: Oxygen furnaces are typically used to heat steel to high temperatures for manufacturing purposes. Unchecked, these furnaces can release significant amounts of CO2 into the atmosphere. Accurate emissions monitoring with the use of moisture analyzers allows manufacturers to reduce these emissions to safer levels in accordance with regulatory standards.

We serve a wide range of business sectors, including power generation, cement, oil & gas, and more.

We are proud of all the products we manufacture, which include moisture analyzers, steam flow meters, and steam flow transmitters. Here, we focus on our steam flow meters and share everything you need to know about these efficient and accurate instruments.

About Our Steam Flow Meters

Our rugged and reliable steam flow meters are made to function as in-line devices that can operate in any flow direction. Steam pressure is converted to velocity as it is forced through a narrowing outlet, known as the throat. That velocity increases until it reaches the maximum speed, which is sonic flow, or the speed of sound. This requires a small drop in pressure across the nozzle, making steam flow meters ideal for operations that vent steam to the atmosphere or open tank. The flow rate is controlled by throttling just before the inlet of the meter.

The meters are mechanical in operation, with no moving parts that are susceptible to breaking. The mass flow rate of steam is clearly displayed on a calibrated panel gauge that shows pounds per hour and kilograms per hour of pressure.

These instruments are used in a variety of applications, including

  • Atmospheric blanchers
  • Steam injection to process ovens
  • Steam eductors
  • Sparging tanks
  • Any applications where steam is exhausted through a nozzle or manifold to a lower pressure

What Is Steam Flow Rate?

Steam flow rate is the rate at which steam is flowing through a pipe, measured in pounds or kilograms per hour.
