QRA (Quantitative Risk Analysis) studies are one of the most important prerequisite of projects involving high risks. Some engineering firms offer paid services to conduct QRA and propose valid recommendations against such project scope. If anyone of you guys did such evaluations, do recommend me ...

ibrahim, cascade control loops with temperature are always tricky ones. You should use PID controller for temperature with a sluggish response initially. Add some derivative factor also. Keep in mind there are two controllers in series working to control temperature. Tune level controller separately ...

Thanks ibrahim for information regarding fired heater. Hysys has a limitation regarding solid handling. As we require solid fuel based boiler to be simulated. Do share if you have any idea how to do that. It will be a fluidized bed combustion based boiler. Also do tell me if there is any other ...

Such a wonderful sharing, thanks proeng. And yeap, we are currently referring that book "Fuel Cell Handbook" by Parsons Inc. Let me give a little background also; we actually are working on a power-plant as a whole, using municipal waste. as you may aware that contains many other metallic oxides ...

Fuel cell is a very interesting, effective and clean way to produce electricity using hydrogen based fuels. However industrial usage of this technology is a big question. If any one has any type of experience related to industrial usage of fuel cell, kindly do share along their feasibility.

ibrahim, in general boigas production is done thru either natural an-aerobic process (uses of enzymes are also common to enhance the rate) or thru catalytic gasification process. Gasification process is further divided based on bed types; Fixed Beds (Downdraft, Updraft, Slagging Fixed Beds) and ...

I have read that document, but this covers the guidelines using some software. Is their any authenticated thumb rule available to verify or design some exchanger without any software.

But this paper has no information regarding boilers and furnaces in HYSYS. I am stuck with a simulation of reforming furnace and a water tube boiler. Can any one guide my thru.
