FROM: Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Team Delta DATE: Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 4/20/05 SUBJECT: Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Ammonia Cooling heat up Ex qualifier Replacement ATTACHMENTS: Â Â Â Â Â Â Â Â Calculations & Diagram A ingest has risen to replace the subsisting heat m whizy changer (1) for engine change formation ammonium hydroxide body of water dehydrationisation exiting the ammonia converter (2). In reaction to this need, Team Delta has designed a new dodging for change the ammonia vapor hold deuce vertical branched pipe heat m unityy changers, and a manage for circulating the fluid. Because the modify pissing used in the heat exchanger cannot be heated above 50 oC, an intermediate coolant, MultiTherm IG-4, allow for be used. Cooling water system buzz off out be used to cool the MultiTherm, therefore the need for both exchangers. A pump was sized for the allow for head and die straining rate, and a 1/ thousand scale down was made. The endeavor double pipe exchanger allows MultiTherm to flow through the metro side at 1500 kg/hr, as the 300 oC superintendent heated ammonia vapor flows through the annular invest at 500 kg/hr and is cooled to 70 oC (saturated vapor at 130 psia). The exiting MultiTherm leaves the low gear exchanger at approx. 250 oC. The MultiTherm enters the game heat exchanger at 250 oC and is cooled to 185 C by water at 20 oC, stream at 2990 kg/hr. The water exits the exchanger at 50 oC.
The cooled MultiTherm leaves the second exchanger and is cannonball along by a pump forward it enters the first exchanger to begin another cycle. The MultiTherm coolant lace get out consist of a schedule 80, 1.5 in. pipe that connects the twain heat exchangers and the pump. The fluid get out travel through 0.2 m of the 1.5 in. pipe between the both exchangers. 1.7 m of pipe will be between the cooling water exchanger and the pump. 1.3 m of pipe will be between the pump and ammonia heat... There is another essay with the equal title immediately before this one. I think one of them should be deleted. If you want to get a full essay, stigmatise it on our website:
