Hello everyone

Is there a way to predict the amount of MeOH to be injected as a function of natural gas flow and water content, in order to inhibit hydrate formation ? In other topics i saw that once formed, hydrate will not dissolve upon MeOH injection, is this right?

Purpurato,

Use the search feature of the forum and you will find several posts on hydrate formation and hydrate inhibition. One link is provided below:

an accurate correlation to predict the inhibition effect of methanol is that of Nielsen and Bucklin

dT = -129.6 * LN (1.0 - XMeOH)

dT = degrees Fahrenheit
XMeOH = 0 ... 0.8

you can calculate the hydrate formation temperature (at specified pressure) with and without methanol injection with many software applications, as example I use Prode Properties (see prode.com).
