The Sample Conditioning System
Proper sample conditioning starts at the sample probe; travels through the sample transport umbilical; continues at the sample conditioning panel; completion of the sample conditioning system does not cease until the sample return point. When temperature is high, then dew point of the gas sample may be above ambient temperature and condensate can alter composition of sample. Therefore, heated sampling probe and sample transport line may be required. Additionally, where ambient temperature is below 32F/0C, sample transport and SCS system must be freeze protected.
Low MTBF begins with a well-designed sample conditioning system. Flow rate control, temperature control, high pressure, multi-stream, reference standards, and alarm systems are only some of the considerations.
