Well....

Way back when I worked at the Exxon oil refinery, I ran the Sulphur 
Recovery Plant section which had a triple pass heat exchanger on two 
separate processor plants. The flow of each triple pass heat exchanger 
was set to enter the vessels in sequence in order to get the maximum 
exchange of heat between the counter-flowing vapors.

The "in sequence" flow pattern worked perfectly well for taking the 
temperature down in stages, each exchanger dropped the temperature by 
more than 40 degrees. However, this required that each vessel have a 
flow controller valve installed upstream to prevent overheating inside 
the vessel.

In the event of reactor overheating or excessive pressure in the 
pipeway, the vapors would bypass the exchanger and go directly to the 
effluent stack to be burnt and avoid burning down the heat exchangers 
or melting the tubes inside the vessels.

Should this be a problem for us to worry about? Is there a chance that 
Macintosh will provide a safety system to divert the excess heat 
through an external cooler system? If so, who will come to your 
location to install it? Will private owners have to have additional 
plumbing installed in their homes? Etc, etc, etc?

This subject is fraught with technical questions and should be 
discussed over a pitcher of beer and an extra large combo pizza. Who 
wants to be the host?
