Abstract: The present disclosure provides a system and method for real time speciated or total measurement of chlorine containing compounds, specifically HCl and RCI, in combustion or process gas generated at refineries. The system may include a sample inlet line, a zero-filter, an RCI converter, an HCl analyzer, and an exhaust line. At least one valve may divert a sample gas to the components of the system. Plain lines and connectors connect the components of the system. The system may be installed as part of a continuous assembly or separate from an industrial operation unit in a facility. The method of measuring the chlorine concentration in the sample gas includes operating the system in a plurality of separate modes such that the sample gas is diverted to the different components of the system and analyzed accordingly.

Abstract: A sampling system including a probe having at least one sorbent trap disposed in a fluid passage that receives and delivers a sample gas, and an in-line temperature measurement located within the fluid passage of the probe. The in-line temperature measurement may be provided by a temperature measurement device having a thermal sensing portion located proximate to, or at, the sorbent trap for providing a more accurate temperature measurement of the trap during sampling of the gas. The sampling system includes a controller configured to receive a signal corresponding to the temperature measured by the thermal sensing portion within the fluid passage, in which the controller may be configured to control the temperature of the sorbent trap based upon the temperature signal.
