Issues regarding the separator after the heat exchanger
Thread Content
As the title suggests, after the design of a heat exchanger, the client requested the addition of a separator, with a maximum allowable pressure drop. How should such a separator be designed? I use EDR to design heat exchangers; do I need to use ASPEN for simulation as well?
A separator needs to be installed downstream of the heat exchanger... Explained in two scenarios: 1. If the gaseous fluid at the top of a distillation tower is condensed using a condenser, then the condensate is essentially what we need, but this condensate may consist of more than two components. In such cases, a horizontal storage tank is usually used, with a partition inside to separate the different components. 2. If condensation occurs within the piping system, then a vertical buffer tank (with a demister inside) is required. You are likely referring to the second scenario; if so, it mainly depends on which type of demister to use, which in turn determines the allowable pressure drop
In my equipment, water flows on the shell side, while the tube side contains substances such as ethanol and methyl formate; everything there is in vapor form
If it is a vertical buffer tank, how should it be designed? Use ASPEN for simulation again?
You might need to first calculate the amount of gas, then determine the size of the equipment required. Finally, you can contact the manufacturer to find out what the pressure loss will be for a mist eliminator of a certain size and height...
