    Outlet temperature of HE at higher inlet temp.

    Drexl, Thanks for the reminder. This scenario (fan trip) was also discussed in our HAZOP. The HE tube is designed to withstand up to 220 ºC. This uncondensed gas will then end up at flare. Design concern is more for the equipment on the liquid / condensed side.

    Outlet temperature of HE at higher inlet temp.

    Guys, Appreciate your input / view on this. How to calculate the new outlet temperature of a fin fan cooler if the inlet temperature is increased. The inlet temperature of the fin fan cooler under normal operation is 130 oC. The outlet temperature is 50 oC. There is one scenario that the...

    Rectriction Orifice (RO) calculation

    Thanks Homayun.. Firstly, my apologies.... the sketch should be as attached below. If i not mistaken, according to pump laws, pump speed has a direct impact to volumetric flow & pump head. Thus I guess this will also help to increase the discharge pressure. Pls correct me if I were wrong. V1...

    Rectriction Orifice (RO) calculation

    Hi guys, Need advice from you all. Refer to attached sketch; After installing new line (line no 4), the header pressure was dropped from 5.0 barg to 4.0 barg (as expected due to additional opening) Line no 1 to 4 are at all at same level & orientation. Hence equal distributed flow...
