Estimate the total heat requirement and size of a vertical emulsion treater to treat a separator outlet stream $($expected BS&W $1\%)$ at operating temperatures $100F$ and $125$ F with the following properties:

Oil flow rate: $1000bblpd$; inlet temperature $85F$; inlet BS&W $15\%$; oil specific gravity: $0\mathrm{.}86$; oil viscosity: $20cp$ at $100F$ and $10cp$ at $125F$; brine specific gravity: $1\mathrm{.}06$ ; specific heat of oil: $0\mathrm{.}5BT\frac{U}{l}\frac{b}{}F$; specific heat of brine: $1\mathrm{.}1BT\frac{U}{l}\frac{b}{}F$; for $BS$&$1\%$ the

$1$

droplet size can be estimated as $d_p($in micron$)=200(oil$ viscosity $(incp){)}^{\frac{1}{4}}$ ; retention time: $20$min; heat loss factor: $10\%.(5$ Marks$)$
