    Flooding in Amine regenerator column

    the severe form of flooding is Puking. puking can destroy trays intensively. in puking the bottom level of tower goes up and down for more than one time, in other word, in level graph versus time you have a wavy graph, a graph like nearly sin(x), I say nearly, not exact sin(x). plugging trays...

    Flooding in Amine regenerator column

    damaging just one part of tray of course cant lead to flooding. I mean, damaging at least in 3 consecutive trays leads to flooding. we faced a terrible flooding in amine regeneration column. this flooding caused to break all of trays in the column. I investigated all parameters that lead to...

    ejector design

    Hello to all in our gas sweetening plant we have 6 trains. I've decided to design an ejector in order to inject the gas of every train which should be flare into sour gas header(the feed of our plant). Have you ever had any experience or study about this issue?

    Corrossion in absorber

    Dear Steve Jones Thank you for your answer. I attached a photo although this is not cearl. feed gas Temperature is 50 deg C. lean Amine Temperature is 55 deg C. maxium Temperature in absorber is 102 deg C in tray 20. the cl ion in amine is 9-10 PPM. gas flow rate is 13 MMSCMD and amine flow...

    Corrossion in absorber

    Hello Our Feed gas in gas sweetening plant has 1200 PPM H2s and 2 mol% CO2.The Amin is DEA 32 wt%. the absorber has 32 trays. maximum temperature in absorber is 102 deg C. the trays are S316 and the body of absorber is carbon steel. we have a corrosion among tray 18 until tray 22, the body and...

    Reducing amine circulation rate

    Dear georgeverghese thank you for your time and reply. Do you think we should decrease amine rate by experience? because the existing formula cant satisfy our aim Thank you in advance

    Reducing amine circulation rate

    Hello In our plant we use DEA to treat sour gas. our sour feed gas has 3000 PPM H2S and 1.7 mol% CO2. gas flow rate is about 7000 m3/hr. Amine rate is almost 330 m3/hr (calculated from known formula and simulation software).outlet gas has 0.18 mol% CO2 and 1 ppm H2s. As you know the outlet gas...

    corosion in amine plant

    Hello to all, In our gas plant, we treat gas with amine solution (DEA). The body of absorption tower is carbon steel and trays are stainless steel. we had a major corrosion in the connection of tray to body of tower. what kind of corrosion we had face? what should we do to repel the corrosion...

    Strainer at pump discharge

    I think it is used for separate some solid particles which are harmful for downstream equipments

    Amine Concentration in Gas Sweetening Plant

    when you increase amine concentration, you face with enhancement in corrosion and energy consumption.

    modification new pipe

    I think you want to joint these two pipe with welding if so, purging is necessary to avoid explosion. after purging if LEL is lower than explosion limit, you can weld.

    MDEA Folw Rate

    how can we calculate MDEA flow rate for Gas sweetenig? in handbooks I found an equation for DEA flow rate but could not find for MDEA. For DEA: L= (4.39 Qg. Xa)/(C.density.Al) Qg gas flow ate. C: amine weight fraction Al= Amine loading Xa= mole of removed acid gas however this equation can not...

    mitigate H2s content

    Dear georgeverghese, Thank you for your time. amine should be injected befor or after of the tools? Do you have any experience about that tools in your plant or elsewhere?

    mitigate H2s content

    Hello there I work in a gas refinary. our feed gas had 1200 PPM H2s(gas flow rate=50 MMSCMD & P=80 bar).we use amine solutions to sweet gas. a new feed gas are added to refinary that has 6000 PPM H2s (gas flow rate=20 MMSCMD & P=80 bar). we want to mitigate H2s content to about 3000 PPM by an...
