Sample handling systems are designed to condition samples from the process stream and provide representative samples to the analyser. This helps in live monitoring and control of the production process. The significance of these systems lies in their ability to maintain the integrity and representativeness of the samples, leading to more reliable data and better decisions.

Process analyzer sample handling systems are important for ensuring accurate and reliable analysis of liquid and gas samples in various industrial processes, especially in industries such as oil and gas, pharmaceuticals, and chemicals, where precise measurements are vital for maintaining product quality, optimising production, and ensuring safety and compliance.

Components of Sample Handling Systems

Sample handling solutions comprise several key components, each serving a specific function to ensure the accuracy and reliability of the analysis.

  1. Sample Probes

Sample probes are the first physical contact with the process stream. They take a sample from the process and it can be used to make a representation of the entire procedure. The location and design of the sample probe are important for minimising the impact of fouling substances and the collected sample being representative of the process conditions. 

Based on the need, the inline probes are used for continuous monitoring or the grab sample probes are used for taking samples at given intervals.

  1. Conditioning Units

Sample conditioning units prepare the sample for analysis by changing its pressure, temperature, and chemical makeup. Such units may include filters, heaters, coolers, and separators among other equipment. To avoid degrading the analysers and maintain the representativeness of the sample, proper conditioning of the sample is critical.

For example, a fluid sample drawn from a high-pressure pipe may need to be depressurized for analysis, while a gaseous sample might require moisture removal before testing.

  1. Transport Mechanisms

The conditioned sample is transported from the extraction point to the analyser by the given transport mechanisms like tubing and pumps. This is because the type of transport to be used in moving the sample depends on the phase of the sample whether liquid or gas as well as distance and the requirement to maintain certain conditions of temperature or pressure. 

For instance, peristaltic pumps are applied to liquid samples that may contain some solid impurities, while gas samples are transferred through heated lines to avoid condensation.

  1. Data Acquisition Systems

Data acquisition systems collect and process the data generated by the analysers. These systems often include software for data logging, visualisation, and analysis, providing real-time insights into the process conditions and enabling prompt corrective actions if necessary. 

Advanced data acquisition systems can also integrate with other plant systems, such as distributed control systems (DCS) or supervisory control and data acquisition (SCADA) systems, for comprehensive process management.

How Sample Handling Systems Work

Sample handling systems follow a structured process to ensure accurate and reliable analysis:

  1. Sample Extraction: The sample probe extracts a representative sample from the process stream.
  2. Sample Conditioning: The sample conditioning units adjust the sample’s properties to match the requirements of the analyser.
  3. Sample Transport: The conditioned sample is transported to the analyser via transport mechanisms.
  4. Sample Analysis: The analyser performs the necessary measurements and sends the data to the acquisition system.
  5. Data Processing: The data acquisition system processes and displays the results for monitoring and decision-making.

Maintaining sample integrity throughout this process is critical. Any contamination or alteration can lead to inaccurate results, compromising the reliability of the analysis and potentially leading to incorrect decisions. 

For example, if a gas sample is exposed to moisture, it could affect the accuracy of the analysis for components like sulphur or hydrogen sulphide.

Types of Sample Handling Systems

Sample handling solutions can be categorised based on several criteria:

Continuous vs. Discrete Sampling

  • Continuous Sampling: In continuous sampling systems, the sample is continuously extracted and analysed, providing real-time data on process conditions. This is ideal for processes where conditions change rapidly and require constant monitoring, such as in refining or chemical reactions.
  • Discrete Sampling: Discrete liquid and gas sampling systems extract and analyse samples at specific intervals. This approach is suitable for processes where changes occur more slowly or where continuous sampling is not feasible, such as in batch processing or environmental monitoring.

Mechanical vs. Automated Systems

  • Mechanical Systems: Mechanical systems rely on manual operation and control. While simpler and less expensive, they require more hands-on management and are prone to human error. Mechanical systems might be used in smaller facilities or where automation is not economically viable.
  • Automated Systems: Automated sample handling systems use advanced technologies to control the sampling, conditioning, and analysis processes. These systems offer higher accuracy, consistency, and efficiency, reducing the risk of human error and improving overall reliability. Automated systems are particularly beneficial in large-scale operations or in hazardous environments where human exposure should be minimised.

Custom Solutions for Specific Industries

Different industries have unique requirements for sample handling systems. Custom sampling handle systems are designed to meet these specific needs, ensuring optimal performance and reliability.
