Prolific Group (PHI) Partners with DXG for Advanced Pollution Control Solutions
We are excited to announce that Prolific Group (PHI) is partnering with DXG to enhance our pollution control solution system. DXG is renowned for its high-precision optical analysis systems tailored for both research and industry, along with its cutting-edge plant-based flue gas analyzers and Continuous Emission Monitoring Systems (CEMS).
About DXG
Established in 1989, DXG achieved a significant milestone in 1998 by localizing high-precision spectroscopic equipment. With extensive experience in optical instrument development and manufacturing, DXG introduced South Korea’s first domestically produced flue gas analyzer.
DXG is a leading designer and manufacturer of gas analyzers and monitoring systems for a variety of applications, including power plants, incinerators, petrochemical complexes, and maritime vessels. This expertise has positioned DXG as a premier manufacturer of flue gas analyzers, representing South Korea on the global stage.
Certifications and Recognition
DXG has earned numerous certifications, including those from the US EPA, the primary standard recognized by Thai authorities for current CEMs systems.
This partnership marks a significant step forward in our commitment to delivering superior pollution control solutions. Together with DXG, we aim to set new standards in environmental monitoring and protection.
What is CEMs? & Why it’s important for the environment?
Continuous Emission Monitoring Systems (CEMS) track and control industrial pollution by measuring and recording pollutants in real-time. These systems are used in industrial plants, power stations, and waste incinerators to monitor sulfur dioxide, nitrogen oxides, carbon monoxide, carbon dioxide, and dust particles using advanced technologies like optical and electrochemical analysis.

CEMS data helps factories comply with environmental regulations, improve processes, and reduce environmental impact, and is also reported to regulatory agencies.
In Thailand, new regulations issued on June 10, 2022, and effective from June 11, 2023, mandate the installation of CEMS nationwide, expanding beyond the previous scope in Rayong province. This regulation requires certain factories to install these systems to monitor emissions continuously, divided into 13 groups based on production units and size. The pollutants monitored vary by factory type, fuel used, and potential emissions, helping industries comply with environmental laws and improve air quality management.
Factories are legally required to measure and report their pollution levels in real time to the Pollution Online Monitoring System (POMs). POMs is a remote monitoring and warning system that displays real-time water and air pollution data from factories on a public website. This allows regulators and the public to monitor industrial emissions and ensures that factories comply with environmental regulations.
CEMS (Continuous Emission Monitoring Systems) can be divided into two main types: Extractive and In-situ. Here are the details and differences between them:
1.Extractive CEMS:
Principle of Operation : Extracts gas samples from the stack and analyzes them using external equipment.
Main Components : Sample collection tube, gas conditioning system, gas analyzer.
Advantages:
- Can measure multiple parameters simultaneously.
- Allows for sharing of analyzers between multiple stacks.
- Analyzers are housed in controlled environments for temperature and humidity, extending their lifespan.
- Easier to maintain and calibrate.
- Limitations: Potential delay in reporting results depending on the length of the sample Point.
- Gas samples need to be conditioned before analysis.
2. In-situ CEMS:
Principle of Operation : Measures pollutants directly within the stack.
Main Technology : Uses optical techniques such as light absorption or light scattering.
Advantages : Provides real-time measurement results. No need for gas sample management systems.
Limitations : May have limitations in measuring certain parameters. Difficult and costly to repair if equipment malfunctions. typically, suitable for monitoring only one stack.
The choice of system depends on the specific characteristics of the facility and the types of pollutants that need to be monitored.
DXG provides a table of Analyzers by Component, where each model can measure different parameters. The selection of the appropriate model depends on the parameters that the facility needs to monitor.
Analyzer by component
1. Extractive Monitoring Type
Gas is extracted from the designated sample point and subsequently directed through a heated sample line to the pre-conditioning facility. This preparatory stage involves the removal of moisture and particulate matter, ensuring that the gas is finely tuned to meet the precise measurement criteria of the analyzer. This approach allows for easy accessibility of the analyzer in challenging installation locations. By installing the equipment in a convenient location, optical gas measurement is achieved through pre-conditioning. The extractive method can vary in configuration based on the required sample handling approach

2. IN-SITU MONITORING TYPE
The In-situ method entails inserting a specialized probe into a chimney or duct through which gas is flowing. This probe enables the instantaneous measurement of gas concentrations within the internal space of the chimney or duct. One significant advantage of this approach is its rapid response time, enabling quick and precise measurements. Moreover, its streamlined installation and operational ease further enhance its practicality, as it negates the requirement for additional pre-conditioning process.
