compute_vacuum_system_power_and_cost(F_mass, F_vol, P_suction, vessel_volume, vacuum_system_preference=None)

Return a dictionary of vacuum system requirements.

Parameters:

• F_mass (float) – Vapor mass flow rate entering vacuum system from vessel in kg/hr (not including inleakage).

• F_vol (float) – Vapor volumetric flow rate entering vacuum system from vessel in m3/hr (not including inleakage).

• P_suction (float) – Suction pressure in Pa

• vessel_volume (float) – Vacuum volume in m3

• vacuum_system_preference ('Liquid-ring pump', 'Steam-jet ejector', or 'Dry-vacuum pump') – Name(s) of preferred vacuum systems
