    Requirements of a chemical/process engineer in a fuel cell manufacturing company

    Hello, I hope I am phrasing this question clearly. I am looking to transition into the hydrogen industry, and one of the big players currently are fuel cell companies. I am curious as to what process engineers actually do in these organisations. Assuming a company manufactures a container...

    System pressure drop in a closed Loop Heat Transfer System with branch connections

    Hello guys First of all I apologise if this has been covered somewhere else, I have done a bit of searching but haven't seen it. As the topic suggests, what I have is a closed loop heat transfer system which heats up process streams around an oil & gas separation facility. The HTF (Therminol...

    Circulation vent design- API 650 Internal Floating Roof Storage Tank

    Hi guys I had posted this topic in another thread, but was advised to post over here instead. Basically I'm involved in a project for a fuel storage facility. We are designing tanks both fixed roof tanks, and internal floating decks, and I am sizing vents for these tanks. The requirements...

    Circulation vent design- API 650 Internal Floating Roof Storage Tank

    Hi. I'm involved in a project for a fuel storage facility. We are designing tanks both fixed roof tanks, and internal floating decks, and I am sizing vents for these tanks. The requirements and calculations for fixed roof tanks are quite detailed in API 2000, however it explicitly states...

    Low capacity Diaphragm pump - sizing suction and discharge

    Hi. I am trying to size a pump for a client, to output chemicals from an injection pot to an overhead tank. The capacity of the pump they want is in the 10gallon per hour range (the chemical injection shot pot is 2 gallons in volume). However, I am getting very small values for suction size...

    Draining a storage tank through attached piping.

    Hi. I am currently involved in a design involving a vessel which is to drain by gravity. I am trying to calculate the maximum velocity of flow [at maximum fluid height in tank]. Now i have seen a lot of papers and even answered posts on here about solving for discharge time through an orifice...

    3 phase [oil, gas, water] flow pressure drop

    Hi. I am doing some work on crude oil separation and am having problems finding correlations / methods on pressure drop calculations for the crude lines. Basically it's a design for a new flowstation, and i am trying to do some preliminary line sizing calculations. Is it OK to assume a...

    How to model changes in flowrate in HYSYS

    I'm a [junior] process engineer, learning how to use HYSYS. The tutorials that came with the software have been helpful, however, when i finished modelling the ACID-gas sweetening with DEA tutorial, there was an excercise which basically asked me to make changes to the model to accept a doubling...
