Hi Guys,
I am a student from Monash University and I have a question regarding to my design project.
Currently my team is building a Oleochemical Plant that major in C16 and C18 fatty alcohol.
I am responsible for the part after hydrogenation reactor.
According to the information, two phase mixture which consist of H2,C16 and C18 fatty alcohol, hydrocarbon, methanol and trace amount of water is transferred to a separator to remove H2.
The two phase mixture is flowing in the pipeline with 200barg and 250 degree C.
Questions
What is the device to reduce the pressure and temperature of the two phase mixture?
I am planning to use a Pressure Reducing Valve to reduce the pressure to 10 barg in order to enter my knock out drum but do anyone know the calculation of PRV? or should I just follow the specification of vendor from the websites.
I also planned to use a heat exchanger to reduce the pressure but what is the formula to calculate the energy consumption for two phase mixture in the heat exchanger?
