2.4.2 Mating of the Process and Analyzer System Flanges
The analyzer is shipped with a 316 SS blind flange plate and gasket mounted inside the oven
enclosure to prevent the process gas from flowing into the compartment before installation
of the sample probe assembly. Check to ensure that this blind flange is in place and secure.
Explosive, toxic and hot gases and molten sulfur may be released once the
stream jacketed ball valve is opened. All company and/or regulatory agency
safety procedures and rules should be adhered to. Breathing apparatus and
personal protective equipment (
ie.
gloves, coveralls and protective eye wear)
should be worn and a safety person(s) should be observing.
Do not take
unnecessary risks even if you believe the tailgas line to be at negative pressure.
Before mounting the analyzer at the process (sample) connection, check to ensure that the
following conditions have been met.
1. The bolt holes in the steam jacketed nozzle flange are large enough to accommodate
the four (4) bolts on the oven cabinet flange
2. The two (2) flanges are correctly aligned
3. A new gasket of proper size and material is available
4. The appropriately sized nuts are available to put onto the oven cabinet flange bolts
(5/8”, 11 UNC).
The sample probe length is unique to each individual analyzer. The length of the
probe is determined at time of ordering based on process pipe diameter and other
relevant dimensions such that the probe provides a minimum of 25% (i.e at
minimum one quarter of the pipe’s inner diameter) penetration into the process
pipe.
If
all the above
conditions are satisfied:
1. Put the new gasket in place and move the oven cabinet into position placing the four
bolts through the steam jacketed nozzle flange holes.
2. Place the four nuts onto the bolts and tighten.
3. Inspect the flange connection using company and/or regulatory agency procedures to
ensure that the connection is leak-tight (no gases are escaping).
4. Check that process gas is not leaking into the analyzer oven.
When the analyzer system is securely fastened to the process sample point flange, make
sure that the oven cabinet cradle is secured to the support structure. This is to ensure that
the framework and support structure, not the flange connection, are bearing the weight of
the oven cabinet.
2.4.3 Installation of the Sample Probe
Once the analyzer system is securely installed on the process pipe, the sample probe
can
be installed by following the procedure below.
1. Lift off the lid from the oven cabinet and place it in a secure location.
