    Where are S.G. or M.W. measurements generally used?

    JWM - thanks for the links - D&V are my fleid. The ASTM D2501 and MW from D&V are new ones on me and I'll check these out. Pumpsonly, its only since learning of compressor surge control that I discovered how MW can be useful for control. I'm unfamiliar with refineries and hence asking the...

    Where are S.G. or M.W. measurements generally used?

    As a follow on to my previous question of dehydrogenisation to produce propylene, I'm trying to get a better undersatanding of how our products are used within a refinery. I would be very interested to know where either S.G. (specific gravity) or M.W. (molecular weight) are measured in...

    Producing Propylene by Dehydrogenation: explanation of the process

    Hi, I recently visisted a refinery to comission our S.G. / M.W. meter. I wanted to get a better undestanding of the process, but due to time limitations and language barrier I could only learn a little. The refinery (can I say the company name on this forum?) made propylene from propane using...
