    Shell and Tube Heat Exchanger Simulation by ASPEN EDR

    Gentlemen, I installed ASPEN exchanger design and rating recently. Currently, I’m trying to be familiar with it by simulating the existing exchanger in the plant I work for. I developed a simulation model for shell and tube heat exchanger based on the available data sheet. When I run the...

    Ice formation downstream LCV

    Thanks Montemayor for your reply,the liquid is hydrcarbon mostly ethane, propane and normal butane. The ice forms on the outside of the pipe. We assume that the hydrate forms on the internal side of the pipe since the level of the boot increases and the level control valve opens fully...

    Ice formation downstream LCV

    Thanks europipe and DRWeig, the valve is two phase valve not flash valve, is the two phase valve considered as flash? i took a sample and i simulated the sample composition and it showed that the hydrate forms downstream LCV. I think the heat tracing is short term solution but what about long...

    Ice formation downstream LCV

    We have drain boot connected to the gas headers upstream the dehydration plant. The liquid from the drain boot is sent to the Blow down system while the vapor is recycled back to the gas headers. The pressure on the gas headers is around 400 psig and the temperature is between 100 to 120 F. The...

    Pump High Discharge Flow alarm

    Gent, last month, we installed two pumps on the outlet of the pressure sewer drum. The function of pumps to pump the hydrocarbon that entrained from our feed gas to treatment plants where gas, oil and water are separated from each other. If the level of the drum reaches certain point, the pump...

    The difference between LPG, NGL & LNG

    Thanks for your reply. The facilite that I worked in is NGL recovery unit. However, in the past it was called as LPG recovery unit. I am confused and I need more clarfication about the difference between them.

    Steam Assisted Flare

    Gent, I am working in LPG facility, we are running our flare system which is steam assisted system. I have a concern because always operation operates the steam that provides the smokeless capacity over the requirement flow. Does this affect the smokeless efficiency because I read through the...
