The quantity is based on solubility of solvent at that
particular thempreture and Pressure.

At room temperture & pressure ,suppose the feed quanity is
as (A = 10 kg, B=15kg, solubility of solvent is 0.150 kg
of B/kg of sovent while that of A is negligible.

Solvent required to extract 15 kg of B = (15/0.150)= 1000
kg.

If we increase the T & / P solubility increase then we have
to take respective solubility value at that particular T
& / P while calculation the solvent.

PROCESS DESIGN - EXAMPLE 21.2 : The names of the flow streams could be represented by : H1 for first hot stream, H2 for second hot stream, C1 for first cold stream, C2 for second cold stream. Data of supply temperature Ts in degree Celsius : 150 for H1, 170 for H2, 30 for C1, 30 for C2. Data of target temperature Tt in degree Celsius : 50 for H1, 169 for H2, 150 for C1, 40 for C2. Data of heat capacity Cp in kW / degree Celsius : 3 for H1, 360 for H2, 3 for C1, 30 for C2. (a) Find the enthalpy changes, dH for all streams of flow H1, H2, C1 and C2 in the unit of kW. Take note of the formula dH = (Cp) (Tt - Ts). (b) Match the hot streams H1 and H2 with the suitable cold streams C1 and C2 to achieve the maximum energy efficiency.
