    What are the main factors to consider when determining the appropriate upgrading technologies (PSA, membranes, etc)?

    As a general rule of thumb, flowrates less than 1500 scfm find membranes to be a cost effective method for producing RNG. At higher flowrates, technologies such as PSA and amine systems may be better options. For all of these systems, the quality of the biogas and purity requirements of the utility play important roles in which technology is the best for each project.

    Kim, thank you very much for replying. As well, I think the Opex of membrane systems is lower? making them more attractive?
