Example 1: $30\mathrm{MMscf}/\mathrm{d}$ of a $0.65\mathrm{sp}$ gr natural gas enters a TEG contactor at $600\mathrm{psia}$ and $100^{\circ }\mathrm{F}$. Outlet water content specification is $7\mathrm{lb}{\mathrm{H}}_2\mathrm{O}/\mathrm{MMscf}$ and the TEG circulation rate is 3 gal TEG/lb ${\mathrm{H}}_2\mathrm{O}$. Estimate the contactor diameter and number of bubble cap trays or height of structured packing required to meet this requirement. Assume $\mathrm{z}=0.92$. Example 2: Determine reboiler duty for conditions in the previous example. Assume the rich TEG temperature entering the regenerator is $300^{\circ }\mathrm{F}$ and the reboiler temperature is $400^{\circ }\mathrm{F}$.
