10. Swagelok Calibration and Switching Module CSM Why Use a Calibration and Switching Module To ensure proper function of an online analyzer and to protect the equipment for maximum uptime all process samples must be conditioned to meet an analyzer s requirements Conditioning includes verifying that a sample is being inserted into the analyzer at the appropriate pressure temperature flow and filtration level Pressure Sie Supplying the sample fluid at the appropriate pressure is important in both gas and liquid systems For gas samples lower pressure will keep the sample away from its dew point and create safer work conditions In addition many injection style analyzers such as a chromatograph depend on constant pressure to ensure a constant injection volume Liquid systems should maintain a higher pressure to keep a sample away from its bubble point Temperature A conditioning system must control sample g sy p Typical Swagelok Calibration and temperature Gases at higher temperature will Switching Module CSM be less likely to reach their dew point or result in water condensation in the sample system Liquids should be maintained at a temperature low enough to avoid bubbling but warm enough to prevent freezing Flow The flow rates set at the sample conditioning system dictate the response time of the entire sample system A typical analyzer flow rate is far too low to result in an acceptable response to

14. ction An ideal stream selector uses double block and bleed valve configurations to switch sample lines without allowing any mixing or leaking from unselected inlets any old internal samples are vented to a bleed line In addition the outlet dead space is flushed through the remainder of the sample system to the analyzer by flowing the new sample around a purge loop A stream selector should also include the inlets from any calibration fluids for the analyzer These fluids can contaminate a sample line in the same manner and should be treated as a separate sample stream to the analyzer A stream selector unit should be installed as close to the analyzer as possible Everything downstream of the stream selector will be exposed to all samples and calibration at different times so minimizing the number of components downstream of the stream selector helps keep the full system clean and easier to maintain Therefore the majority of sample conditioning functions should be done upstream of the stream selector where sample purity is less a concern Key Features The CSM is built on the Swagelok MPC platform utilizing the Swagelok stream selector valve SSV product which allows the user to select the configuration required for the specific system The standard model described here accepts up to ten process and two calibration fluids either all liquid or all gas The main function of the CSM is to condition and select process streams or to select a
