WE are designing a heat shield for our flare for an offshore application. This heat sheild is located at the base of the flare tip to protect the stack structure. We have used flare sim to calculate the heat load and temperature and submitted to the heat shield vendor (we have used standard...
Hi
I am looking at an oil and gas platform. I have worked out the fail scenarios if the main instrument air system is cut. The case i am looking at is if the air system is cut what is the maximum load on the flare header "blowdown". Alas alot of my valves on the platform and blowdown valves...
Hi All
I have an oil and gas platform. I have an LP separator with two feed sources. One source comes from an HP separator with pressure 85 barg which conveys an oil stream to LP separator. The other feed source at approx 16 barg has low pressure well fluids. I am looking at the gas blowby case...
I am looking at sizing the lines upstream and downstream of a liquid case psv. My pipe contains produced water i..e water with a very small amount of gas 1%. I have sized the inlet for 3% pressure losses as per api520. Is there any guidelines or good working practices w.r.t max velocity...
WE can have a scenario when the tube rupture occurs, in my case this is the aftercooler on the 3rd stage compressor this is a bursting disc case. In coincidence we can also flare the production. Note this is only what i would called a temporary flaring scenario. WE have PCVs on the 1st stage...
Question on flare Scenarios
Note this for an oil and gas platofrm offshore.
I have been asked to look at the production flaring case on a platform. All the literature for the platform indicates the worst case in this scenario is a tube rupture coincident with production flaring. WE have on my...
Hi everyone
What i am trying to do is size new control valves on the cooling medium output side.
What i have is a shell and tube heat exchagner where the process side flowrate is diminishing as a function of time. The cooling water in this case seawater is being manipulated to control the...
Hi
This platform is quite old. When i state the min design temp is -45 then they chose the pipe spec for carbon steel. The original blowdown calcs dont reach the -45 limit so they were OK. Originally a few years ago the system was allowed to run hotter. Nowadays we export the gas the temp...
Thanks
I have put a -45 pipe spec all upstream of the system. Alas we also looked at the wall temperature upstream and this is fine. So relatively happy on the upstream section before BDV. Its the downstream section im more concerned about. I have considered putting a low temp high pressure...
Hi
I am designing a blowdown system for a gas export line topsides (modification to an existing plant). The calculations on hysis indicate we are 10 degrees below the minimum design temperature on the flare header.
I am using the detailed heat loss in the software as well.
Our piping have...
