    Back to basics flow vs density relationship in an orifice

    Hi guys, Why is the relationship between the mass flow and the density not linear in flow through an orifice?

    PSV flange leak testing

    I am installing a new PSV on an HP methanol pump discharge line and I need to prepare leak test P&IDs for new flanges. This is a brownfield job therefore my issue is there are no isolations downstream of the PSV so I was wondering how to leak test the PSV flanges as it is not possible to create...

    Thoughts on a gas condensate line being decommissioned

    Hi there, I'm no specialist in decommissioning of pipelines, so would like some thoughts from those with some experience in this. I've got a gas condensate line that's been shut in for several years now and looking to be decommissioned. First task is to actually work out what could actually be...

    Degasser design

    Hi, I am looking to size a degasser at a high level (i.e. I don't yet need to specify liquid levels) and wondered whether I should size it for a horizontal two phase or three phase? At first I thought two phase, but then wondered that maybe I need to consider three phase because as well as...

    Blowdown with water vs water free basis

    Hi, Can anyone advise, as the results I am getting are confusing the theory I thought! I did a blowdown in Hysys of a vapour phase stream with a fire case with water and then removed the water and normalised my components and did it on a water free basis. I had thought that the water free...

    Advice on a peak blowdown rate required

    Hi guys, I need some advice. I am doing some work with flarenet so I require some peak blowdown rates for my system. My blowdown valve is a globe valve (CV = 77). I am going to use hysys, but I am not sure about the vapour flow equation in Hysys, so I wonder if anyone knows a way to convert my...

    Annulus vent ideas?

    Anyone got any ideas for what to do with an annulus vent which is not able to be tied into the flare system because the flare is too high a pressure for this to be possible?

    Control valve with flashing across it

    Hi everyone, I have an existing control valve and I wish to check it is adequate for some different flowrates. When I model the valve in Hysys with a pressure drop, I notice that the liquid phase upstream of the valve becomes liquid with a bit of vapour downstream. Do I need to use any...

    Gas lift pipeline pressure after cooling down

    Hi, I have a 17 km gas lift pipeline (no water present in the gas as the gas has been dehydrated). It is at a temperature of 41 C and 220 barg. The pipeline is closed in and then left until the temperature has cooled to seabed temperature of 8C. How do I work out what the new final pressure...

    PCV or LCV control setup?

    I'm trying to work out whether I can use a level control setup for my solution. I've attached a schematic showing only the water stream which I am dealing with. My pump is a positive displacement pump. At the moment my configuration uses a pressure control setup but I am not sure if this is...

    Pumps in parallel with different discharge pipework

    Hi All, In many references I have come across regarding use of pumps in parallel, all examples and theory covers a situation where the discharge of the second pump's pipework is identical to the first pump's pipework, up until their point of rejoining. However, in reality, this sometimes isn't...

    Pipeline settle-out conditions

    Hi, Can anyone provide some steps to help me determine the settle-out pressure of a pipeline? I am going to be doing a blowdown calculation of the contents in the pipeline, but I need initial conditions, which will be the settle-out pressure. The pipeline departs at a pressure of 44 barg and...

    Well start-up/revival

    I was wondering whether anyone could provide some assistance on their experience of what has been done in a situation where a well has been shut-in for a period of time (say during a compressor wash or period of low gas demand) and is required to be revived. There is currently no artificial...

    Glycol regeneration package ESDV fails to close

    Hi All, I am reviewing a case where an ESDV on the liquid outlet line of a glycol skimmer did not close. This line feeds into part of the glycol regeneration package (more specifically the glycol regenerator heater). If such an event was to occur in the future (it has currently been...
