High Pressure
how to reduce the high pressure of liquid phase stream which consists of melamine and urea?
i'm doing the design of production of melamine. The liquid stream which out from reactor is 8000kpa and 400celcius.The stream consists of melamine and unreacted urea which in liquids phase. the pressure is too high. what equipments that i can used to depressurized the liquid stream? any body can give me the answer?
First you need to cool it in a heat exchanger below about 80 celsius, otherwise it will boil. Then use adiabatic throttling to reduce the pressure to atmospheric. You will need a spring loaded pressure relief valve so as to maintain the 8000kpa pressure in the reactor. Make sure that there is plenty of surface area in the valve, or it might clog because of precipitated unreacted urea. Maybe have two pressure relief valves so that it is easy to switch to the other one for maintenance. You could also have a filter upstream of the valve to catch some of the urea crystals. Depending on how much urea is in the stream, you might need a cyclone separator.
