In response to this need, Team Delta has designed a new system for cooling the ammonia vapor utilize deuce vertical bifurcate piping heat exchangers, and a fondness for circulating the fluid. Because the cooling micturate apply in the heat exchanger cannot be heat above 50 oC, an intermediate coolant, MultiTherm IG-4, allow for be used. Cooling water system get out be used to cool the MultiTherm, hence the need for both exchangers. A pump was sized for the appropriate head and die hard rate, and a 1/ 1000 scale down was made. The initiative double pipe exchanger allows MultiTherm to flow through the resistance boldness at 1500 kg/hr, as the 300 oC superintendent het ammonia vapor flows through the annular put at 500 kg/hr and is cooled to 70 oC (saturated vapor at 130 psia). The exiting MultiTherm leaves the first exchanger at approx. 250 oC. The MultiTherm enters the endorse heat exchanger at 250 oC and is cooled to 185 C by water at 20 oC, flowing at 2990 kg/hr. The water exits the exchanger at 50 oC.
The cooled MultiTherm leaves the second exchanger and is quicken by a pump before it enters the fir st exchanger to let another cycle. The Mul! tiTherm coolant loop will consist of a roll 80, 1.5 in. pipe that connects the two heat exchangers and the pump. The fluid will give way through 0.2 m of the 1.5 in. pipe surrounded by the two 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...
