    Multibedreactor with small diameter

    Hi Folks, I am currently working on a study about revamping the reactorsection of our Lubeoil-Hydrogenation plant. This means, designing a new Reactor (with multiple beds and gasquenches) for it. When doing the calculation for the needed insidediameter of a new reactor considering having a...

    HYSYS – Simulation of a distillation column with defined cutpoints for sidedraw

    @all: see my specs in the attached pdf. @TD2K: Wny are you specifying both the vapor and liquid D86 points --> warong post by myself...see pdf attached My question: is there an easier way to run the simulation than using these three specs? Regards, Andre

    HYSYS – Simulation of a distillation column with defined cutpoints for sidedraw

    Thanks George, I defined two Specs (in HYSYS called 'cutpoint') to receive a defined draw: Spec1: Stage 13 Type: D86 Temp: 200°C Phase: Liq Spec2: Stage 13 Type: D86 Temp: 300°C Phase: Vap Let's say stage 13 ist my stage for the sidedraw. For solving the simulation, I have to vary the...

    HYSYS – Simulation of a distillation column with defined cutpoints for sidedraw

    Dear all, I am trying to find the best way to simulate and design a distillation column with a defined cuts for a sidedraw. The sidedraw will be the mainproduct in this operation. Example: Assay Boilingrange: 150°C to 350°C Sidedraw with CUT: 200-300°C Which type of Subflowsheet and...
