    API618 Recip compressor Piston vent hole question.

    Hi all, In our refinery we have a issue with an recip compressor where there is a mark on a liner at the cylinder. OEM said possible cause is from vent hole at the piston ring groove because the jet pressure from this hole would make such mark. and for this issue, OEM told us to make another...

    Reciprocating compressor

    Hi, I am doing a case study and wonder whether my thought is valid or not. background: - Recip Compressor valve damaged, because of fouling due to uncleaned piping. - It was working well but later it hits discharge pressure alarm. - gas composition changes thus mole weight varies. - worry...

    Super-heated state

    Hi, I read the one of the incident report that pump explored by closing suction and discharge valve closed. It was water pump so, the temperature increased and the water that is kept between two valves became super-heated state, and pressure increased. Thus, it exploded. and I just wonder...

    Torsional natural frequency

    hi all, I am doing some calculation with regards to torsional natural frequency given one set of equipment with motor and pump along with respected moment of inertia for both. and it also gives you "the first torsional natural frequency" and here I really don't understand what it mean by "...

    Sticking?

    hi all, Can anyone please explain what it mean by sticking which will lead to local control failure? I tried the google, but it does not show the how such phenomenon is formed, and what real is. thank you,

    Few questions on compressor failure.

    I started work recently as a rotating equipment engineer and currently studying by myself with compressor. and while studying I just wonder about few failure modes Failure mode 1. If pressure does not build up properly due to old(reused) impellers, can these cause rotor imbalance as pressures...

    why do we use Nitrogen for storage?

    Good morning everyone. I have found that in many industries storage is done with the filling the gas inside and most of time with Nitrogen. This is also applied to rotor storage and it is recommended to use Nitrogen of (minimum 1.5bar). I know this has been like this for years but I just...

    What does Kernel size indicate?

    I have been reading an article on the auto-ignition for my thesis, and wonder about the bubble(spark) that produced in auto-ignition process. First question is What does this Kernel(bubble) indicates? I understand it as just an evidence of auto-ignition during combustion process but does it...

    how high is the hig pressure mean?

    I am reading papers relate to the viscosity of the gas mixture which is one of the consideration in an experiment. It seems there are various numerical ways to calculate the viscosity of the gas mixture. For instance Wilke, chapman and etc. So I tried to use some of them to compare with the...

    DME gas through the regultor problem.

    I am currently setting up a combustion experiment and I encountered a problem with a fuel I am using. For this set up, I am using DME gas and thread type is POL. When DME is released through the regulator, it gets really cold that it almost freezes over in few minutes. (This is beacuse of...
