Endress+Hauser 4-1
4 - SAMPLE CONDITIONING SYSTEM
The Sample Conditioning System (SCS) has been specifically designed to
deliver a sample stream to the analyzer that is representative of the process at
the time of sampling. To ensure the integrity of the sample stream and its
analysis, care must be taken to install and operate the SCS properly. Therefore,
any personnel intending to operate or service the analyzer and SCS should
have a thorough understanding of the process application and the configuration
of the SCS.
Most problems experienced with sample systems tend to result from operating
the system differently than intended. In some cases, the actual process
conditions may be different than originally specified (e.g., flow rates, presence
of contaminants, particulates, or condensables that may only exist under upset
conditions). By establishing understanding of the application and the design of
the system, most issues can be avoided altogether or easily diagnosed and
corrected ensuring successful normal operation.
If there are any remaining questions concerning the design, operation, or
maintenance of the SCS, contact “Service Repair Order” on page B-25.
About the SCS
Endress+Hauser sample conditioning systems are designed to filter incoming
gas, as well as control pressure and flow to the analyzer. The SCS uses a
7 micron particulate filter and a membrane separator that removes entrained
liquids or particles from the natural gas stream before they enter the analyzer.
Because Endress+Hauser analyzers are immune to vapor phase contaminants
found in natural gas, using the particulate filter and membrane separator
prevents any contamination of the analyzer.
Personnel should have a thorough understanding of the operation
of the H
2
S analyzer and the procedures presented here before
operating the sample conditioning system.
The process sample at the sample tap may be at a high pressure.
A pressure reducing regulator is located at the sample tap to
reduce the sample pressure and allow operation of the sample
conditioning system at a low pressure. Use extreme caution when
operating the sample probe isolation valve and field pressure
reducing regulator.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before operating
the SCS.
