Hello everybody,
i need help with the following situition;
we have a knock out drum before our Cold flare, this vessel is made from SS and during extensive flaing level could rise to about 35-40% of cold NGL minimum -50C, the ambient temprature is warm about 20-25C how could i determine how long...

I work for an LNG company 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 reason is tray damage.

thanks for your answers, also i want to know, if i pass the FE exam and licienced as an EIT in a state can i work there even if i'm graduated from a university outside the USA.
i visited the NCEES web site but couldn't find the section to send them mails regarding my questions!!!
Hello all,
i'm a chemical Engineer graduated from a university outside the USA and the NCEES agreed with a university in my country to offer both the FE & PE exams for local engineers.
i'm taking the FE exam next October and i have those questions;
1) what will happen next if i pass the FE exam...
i'm planning on entering the FE exam next October. i graduated 2 years ago and so i think i'll need lots to pass the exam, so what do you think is the best books to study from?!!
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?
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...
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...
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...
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...
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...
