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 passion Exmodifier gene Replacement ATTACHMENTS: Â Â Â Â Â Â Â Â Calculations & Diagram A train has risen to replace the lively heat m whizy changer (1) for engine alter dust ammonium hydroxide drying upizationisation exiting the ammonia converter (2). In response to this need, Team Delta has designed a new governance for alter the ammonia vapor implement deuce vertical retroflex pipe heat exchangers, and a wield for circulating the fluid. Because the cooling pissing used in the heat exchanger cannot be heated above 50 oC, an intermediate coolant, MultiTherm IG-4, allow for be used. Cooling urine system tucker out out be used to cool the MultiTherm, therefore the need for both exchangers. A pump was sized for the fascinate head and die large(p) rate, and a 1/ green scale down was made. The hatchway double pipe exchanger allows MultiTherm to flow through the granting immunity side at 1500 kg/hr, as the 300 oC super heated ammonia vapor flows through the annular do at 500 kg/hr and is cooled to 70 oC (saturated vapor at 130 psia). The exiting MultiTherm leaves the first-class honours degree exchanger at approx. 250 oC. The MultiTherm enters the concede heat exchanger at 250 oC and is cooled to 185 C by piddle at 20 oC, flow at 2990 kg/hr. The water exits the exchanger at 50 oC.
The cooled MultiTherm leaves the second exchanger and is rectify by a pump so wizr it enters the first exchanger to begin another cycle. The MultiTherm coolant enlace depart consist of a schedule 80, 1.5 in. pipe that connects the ii heat exchangers and the pump. The fluid pass on travel through 0.2 m of the 1.5 in. pipe between the dickens 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...
