2 - SCS O VERVIEW Personnel should have a thorough understanding of the operation of the OXY5500 analyzer and the SCS, including procedures presented here, before operating the sample conditioning system. The process sample at the sample tap may be at a high pressure. A field pressure reducing regulator is located at the sample tap to reduce the sample pressure and enable operation of the sample conditioning system at a low pressure.
OXY5500 Analyzer About the SCS Refer to the system drawings and schematics found in Appendix A of this manual for your specific system configuration. For a typical full-featured SCS, as shown in Figure 2–1, sample gas enters the sample conditioning unit [at the specified supply pressure set by an upstream regulator] via the sample supply port, passes through a shut-off valve, pressure regulator that maintains constant pressure in the measurement manifold, and membrane separator where any liquid in the stream is removed.
SCS Overview The flow exiting the bypass loop is combined with the flow exiting the measurement manifold and sent out the sample return port to be vented to a safe location. Typical SCS Component Overview Some of the typical components used in the SCS will be described in this section.
OXY5500 Analyzer Figure 2–2 Analyzer and probe interface Sample Conditioning System Filters A guard filter is typically installed at the inlet to the SCS with a fine element to protect the flow controllers, flow meters and pressure regulators from fine particulates.
SCS Overview Sample Transport Tubing Sample transport tubing must be made of an appropriate material, which may be coated, and of an appropriate diameter for the application. Many times the sample transport tubing must be heat-traced to prevent sample condensation or to prevent fluctuations in measurement due to changes in ambient temperature.
