This can be done by creating a material stream with specified T & P conditions, required compositions and then adding a utility of type binary phase envelope.

<span style="font-family: arial, sans-serif; font-size: small; line-height: normal;">I obtained the VLE data and exported the data to excel, however, l managed to get the range where it lies using the NRTL method: it lies between 0.87 and 0.9 mole fraction of ethanol. My question is how do l pinpoint the exact composition. Is there anyway l can attach the files for your reference, may be your email address. Thanks.</span>
