    hydrate formation inhibition with methanol, accuracy, Prode Properties

    dear experts, can you give an estimate of errors when estimating hydrate formation conditions for a natural gas stream + methanol as inhibitor with prode Properties ?
    Thanks !

    Re: hydrate formation inhibition with methanol, accuracy, Prode Properties

    there are a few values published by developer,

    [link Point to another website Only the registered members can access]
    I have verified some of these points (ask Prode for the list),
    with simplified model for hydrate formation pressure you may expect an error in the range 3-15% (depending from structure and temperature),
    errors in hydrate formation temperature are in the range 1-2 K

    the complex model is more accurate,

    when adding methanol as inhibitor erros are about the same (with the specific parameters provided for CPA PR Cubic Plus Association or other models,
    however I suggest to contact Prode for more accurate figures...

    Re: hydrate formation inhibition with methanol* accuracy* Prode Properties

    I can confirm accuracy for complex model (that available in commercial version)*
    comparing with free version errors are (in many cases) about 50% lower
