    Convert On-Off Valves to Control Valves

    @LittleInch, Thanks for the suggestion, but I don't want to lose the idea of automation control in the system process.

    Convert On-Off Valves to Control Valves

    @shvet, I need a control valve for a small project (domestic use). It's applied to small flow rates up to 15 lpm, max pressure up to 5 bar, and it doesn't need high accuracy. What I need is for it can be fully closed, half open, and fully open and affect the flowrates at downstream...

    Convert On-Off Valves to Control Valves

    Background Story: I'm looking for a control valve that can control the stream to the desired flow. What I found in the domestic market are mostly Actuator valves, an On-Off type valve. I asked some sellers if it is possible to make that actuator to control the stream flow (like with 25%, 50%...

    Vent and Drain in Custody Meter

    I see, thank you again for your answer. Now I have better idea wether to add them or not. I would let people knows that I'm still open for their answer and experience. More story means better insight.

    Vent and Drain in Custody Meter

    @LittleInch thank you for your response. When I'm looking at custody meter P&ID/GA drawing, either for gas or HC liquid, some stream configuration has vent or drain after strainer or gas filter but some other dont have it installed to the metering stream even after the branch to the proover...

    Vent and Drain in Custody Meter

    Hi Engineers, I want to ask. Are PRV + vents and drains actually needed in the Custody meter stream? Or does it serve its purpose only during maintenance?

    Increasing Raw Natural Gas Dew Point and Molar Flow Rates

    oh yeah, you're right @1503-44. Above are the Hysys calculations if I follow the gas flow rate at 17 MMSCFD. Below are the calculation of the what-if scenario when the raw gas flows at 30 MMSCFD, and it barely reaches 200 bbl/days. Unless the specs of the equipment output they give me are...

    Increasing Raw Natural Gas Dew Point and Molar Flow Rates

    Thank you all @1503-44, @GBTorpenhow, @MortenA for your answer~ @GBTorpenhow, the initial problem is the client wants HC liquid product to be ~1300 bbl/day. since the raw natural gas is dry (I just know it's unusual, perhaps I'm going to ask the client to make sure again) I need to reduce its...

    Increasing Raw Natural Gas Dew Point and Molar Flow Rates

    Thank you for the reply. - The raw gas composition (by Hysys calculation) is 17 MMSCFD, but the client gave me the expected refined gas spec (after the separator) to be 30 MMSCFD. Thus I wonder if molar gas flow can be changed by physical process or not; like changing its Pressure, Velocity...

    Increasing Raw Natural Gas Dew Point and Molar Flow Rates

    Hello, I'm new in natural gas processing and refining. I have this problem in that I need to separate HC liquid from Raw Natural Gas fresh from the well (@ 200 degF). The gas composition has very low water composition and low heavy carbon composition, thus its dew point temperature is around 97...
