Abstract
Abstract This work reports high-quality isothermal vapor–liquid equilibrium data for ethane + ethanethiol (or ethyl mercaptan) at 303 K, 323 K and 343 K and pressures up to 6.25 MPa. A sapphire-tube equilibrium cell with an online micro sampler and GC-TCD are employed to measure equilibrium phase concentrations at specific temperatures and pressures. Peng Robinson equation of state with classical alpha function is found adequate for data treatment and thermodynamic modelling.
