En una planta de fertilizantes, se utiliza un sistema de absorción para recuperar amoníaco de una corriente de entrada de gas que contiene 70\% de amoníaco (NH3) en nitrógeno (N2). Se sabe que la torre de absorción puede recuperar por una de las corrientes de salida el \( 95 \% \) del amoníaco que ingresa (por esta corriente sólo sale amoníaco), y además que la corriente de residuo tiene un muy bajo porcentaje de amoníaco, y un flujo molar de \( 60 \mathrm{~mol} / \mathrm{h} \). a) Realiza el diagrama de flujo de este proceso. b) Para verificar que el problema se puede resolver, realiza el análisis de grados de libertad. c) Escribe (sin resolver) todas las ecuaciones que puedes plantear para este problema (balances de masa, relaciones del proceso y relaciones de composición). d) Ahora si! Emplea las ecuaciones escritas en el punto anterior para calcular todos los flujos y fracciones molares desconocidas.

Step 1
- Corriente de entrada: Contiene 70% de NH3 y 30% de N2. - Corriente de salida 1: Recupera el 95% del NH3. - Corriente de salida 2 (residuo): Tiene un flujo molar de 60 mol/h y un bajo porcentaje de NH3. Show more…

An absorber must recover 99% ammonia from an air-ammonia feed stream, using water as the absorbent liquid. The ammonia content in air is 20 mol%. The temperature of the absorber is maintained at 30 °C by cooling coils and the pressure is 1 atm. a) What is the minimum flow rate of water? b) For a water flow 40% higher than the minimum value, how many global transfer units based on the gas phase are needed?

You are a process engineer working on an ammonia synthesis plant. 100 ton/h of a feed with the following compositions is fed to the plant: Component mol% mol weight H2 40.0% 2 CH4 10.0% 16 CO 45.0% 28 CO2 5.0% 44 The feed is first fed to a CO-shift reactor where the carbon monoxide (CO) is converted to hydrogen via the CO-shift reaction: CO + H2O CO2 + H2. Not all the CO in the feed is converted and the product stream from the reactor contains 4mol% CO. The water for the reaction is added to the reactor as steam. Calculate the molecular weight of the feed stream and convert the 100 ton/h to kmol/h feed. Calculate the mol flow rate of each component in the feed. (5 marks) Calculate the mass flow of water to the reactor. (4 marks) Calculate the mol flow rate of each component in the reactor outlet. (4 marks) 85% of the hydrogen is recovered as pure hydrogen in a pressure swing adsorption unit (PSA). The pure hydrogen and nitrogen from an air separation unit (ASU) is fed to an ammonia synthesis reactor. What is the expected mass of ammonia that will be produced in ton/h? The ammonia synthesis reaction is: 3H2+N22NH3 (NH3 mol weight = 17kg/kmol) (2 marks) The feed to the CO-shift unit is at a temperature of 350°C and a pressure of 25 bar abs. Calculate the line size for this feed line. Use a velocity of 30m/s as economic gas flow velocity. (6 marks) What size would be a good guesstimate for a flow control valve in this feed line? (2 marks)
