Continuous Emission Monitoring Systems (CEMs) are also known as chimney monitoring systems, chimney gas meters, stack pollution meters, and so on. According to a Department of Industrial Works notification, these CEMs are required to be put in factories to assess air pollution.
The law says that factories in certain groups have to share pollution measurement data every day. They have to report more than 80% of their total operational hours each day and do so in real time, which means that on average, every chimney in a plant that has polluted the air has to report its data within an hour.
If your plant is required to report measurement data, installing CEMs for each stack can quickly become a costly endeavor. Depending on the size and complexity of your plant, the cost of installing CEMs can be overwhelming. This is especially true if your plant has a large number of stacks that require monitoring. It's natural to question if there's a method to cut down on the expense of installation.
The answer is in today's article.

1. Your plant has multiple chimneys with the same production or combustion fuel.
2. The boiler and the diameter of those chimneys are the same size.
3. There is no or only a 10% difference in gas concentration and air flow rate between those chimneys.
Congratulations! You can save up to 70% on CEMS installation costs!
You can save money by combining the analytical instrumentation systems if your chimney meets the aforementioned requirements. This method is called time-shared measurement.
This cost-saving opportunity is a result of the time-shared measurement method, which allows for multiple chimneys to be monitored with the same range of air pollution concentrations. By taking advantage of this method, you can significantly reduce your CEMS installation costs without sacrificing accuracy or compliance.
The next step, if your facility has a chimney that satisfies the aforementioned requirements and you want to implement time sharing measures, is to submit the necessary paperwork to the Department of Industrial Works for approval.
Installation cannot begin until the necessary permits have been obtained from the Department of Industrial Works.
