Problem $1$:

Estimate if there is any hydrate formation for the following problems, if so$,$ calculate

the amount of $85\%$ EG inhibitor needed to be injected.

a$.50MMSCFD$ of gas contains $70\%C1,20\%C2,10\%CO2$ is going through cooler to

cool the gas from $600$ psia and $80$F to $595$ psia and $20$F$.$

b$.100MMSCFD$ of $1000$ psia and $70F$ contains $90\%C1,10\%C2$ is going through

turboexpander to $250$ psia. Assume isentropic with efficiency $100\%.$

c$.$ Solve the section $($a$)$ by using $95\%$ methanol.
