Figure S-1-1 Sampling Train for Vinyl Chloride Releases

In Figure S-1-1, a sample is drawn through a probe located in the stack.  Also located in the stack or vent is a pitot tube which is connected to a manometer outside the vent.  The sample then flows through a series of optional impingers or condenser to remove moisture which are connected to a pump followed by a needle valve and rotameter to control and measure the flow.  The exhaust from the rotameter is directed either to the sampling bag by a quick connect coupling or to atmosphere for purging the sample lines before sampling.

Figure S-2-1 Sampling Train for Measuring Reactor Opening Releases

In Figure S-2-1, a sample is drawn through a probe located in the reactor.  The sample line is connected to a pump followed by a needle valve and rotameter to control and measure the flow.  The exhaust from the rotameter is directed either to the sampling bag by a quick connect coupling or to atmosphere for purging the sample lines before sampling.
