$($a$)$ A triethylene glycol dehydration plant receives $80$ MMscfd water

saturated natural gas $($molar mass $22)$ at $110\backslash$deg F and $285\mathrm{.}3$ psig. The dry

gas leaves the plant at $40\backslash$deg F and $485\mathrm{.}3$ psig. Calculate the triethylene

glycol circulation rate in gallons per minute. Use $1\mathrm{.}5$ gallons of TEG

for $1$ lb of water in the inlet gas as the industry standard.
