Can't say I did any calculations, but we have a very similar operation, except we're just cooling, not condensing tube side. We keep the level enough to just keep the tubes submerged. So the disengagement area is just 30inx19ft at the water surface with ~7-8" from the surface to the nozzles. The...

The car is insulated and the more I think of it, heating from the outside would probably be a long, expensive process. My current line of thinking is getting ~100+ ft flexible stainless (compatibility reasons) hose and snaking it from the manway to one end to the other end and back out the top...

We have a 24,000 gal frame type tank car ~¾ full of product and the steam coils have failed. What are our options to melting the material and clearing the railcar recovering the product? The product melts at 250°F. The car owner won't let us cut a head off and shovel it out. Reacting or...

Thanks everybody for replying! The reaction mixture is organics and is kept under pressure, ~150 psig, to remain a liquid. So the process stream is only giving up sensible heat. With the U value I calcuated, and dumping it into ChemCad it showed the heat transfer would be close. In the event...

We have an exothermic process generating upwards of 9 million BTU/hr of energy at 355 to 370°F on each of two reactors. Currently the hot process liquid is recirculated on each reactor at 1800 gpm cooled with cooling tower water (CTW) to maintain temperature. Since there is no viable heating...
