    Tower internals inspection

    I'm a process engineer working for an LNG and we have a stripping tower containing 20 trays, we are facing a disturbance in process regarding the specs of liquid coming out of the tower and one of the possible reasons is tray damage. We can't shut down the plant and so we need to perform an...

    Separator carryover

    yea it works for a couple of days after any opening for the vessel. ofcourse there is a big possibility for hydrate formation, could you please tell me how this could affect the separator efficiency?

    Separator carryover

    tickle, thanks alot for your contribution, what we are sure about is that there isn't anything wrong with the LCV. also if you mean by gas break through gas blowby with the drained liquid then we ofcourse don't have that as gas pressure is 50 Bar while liquid drain is collected in a vesel of 3...

    Separator carryover

    Hi, currently we have a problem at the gas plant i work for. we have a dehydration system it consists of the following: a horizontal separator vessel to separat the free water up to 10 microns in the feed gas, after which the feed gas enters a filter coellescer to separate water particles up to...

    Output of PV vs Flow

    thanks for your replys, i'll try to add more information. the vessel has 2 PC with 1 PV each. one PC controls the low pressure inside the vessel by allowing nitrogen to flow in when the pressure is low while the other controls the high pressure by flaring excess gases at high pressure. we are...

    Output of PV vs Flow

    i'm having a problem that's driving me crazy, we have a PV that controls the pressure in a a vessel through allowing gaseous nitrogen into the vessel to increase pressure whenever needed. we can view the output of the valve on the DCS, however we can't track the flow of nitrogen into the vessel...

    a couple questions regarding fluid flow

    i'd like to have an indepth idea about these topics; 1) what is Choke velocity and how to calculate it? is it just mach 1? 2) what's surge in compressors and minimum flow in pumps? and how to calculate them? 3) regarding compressors we have 6 turbocompressors that are controlled via a system...
