Review of Scientific Instruments. 85(4): 045123-. doi:10.1063/1.48715870034-67481089-7623 (Online)isidoc: AH1ZNpubmed: 24784675https://hdl.handle.net/10321/4688The measurements of hydrate dissociation points are generally achieved using the well-established isochoric method. This method implies determination of the total pressure of the system under study, as a function of temperature. It is quite time consuming, especially at higher pressures. Working at higher pressures requires equilibrium cells with thicker walls, which compromises on fast heat exchange. The use of a variable volume cell is therefore quite attractive as it allows for the measurements of hydrate dissociation pressure under isothermal conditions. This paper describes a transparent variable volume cell used for efficient and rapid measurements via the isothermal procedure.4 pPrinten02 Physical Sciences03 Chemical Sciences09 EngineeringApplied PhysicsArticle2023-03-2710.1063/1.4871587
