Do you know about frequent failures in an industrial furnace, in particular those located at Z-neck and SQE?
Also, could you suggest a detailed book regarding furnaces operations and maintenance?
How can I calculate the quantity of liquid (in kg/s or cm3/s) entrained by vapour, given the quantity of liquid in a pool and the quantity of vapour flowing through this liquid pool? Thanks.
What is the typical purity of water demineralized by anionic and cationic resins? In particular, how much ppm or ppb of salt it typically contains? Thanks.
It exist any equation to calculate fouling factors? In particular I am interested to the case of demineralized water in closed loop at low pressure and a temperature around 50-70 °C. Thanks.
What is the typical time period required before to clean an heat exchanger? In particular I am interested to know this information for a tubular heat exchanger or evaporator or reboiler (e.g. shell and tube or double tube) in the case in the shell are circulating demineralized water and steam...
Do you know any kinetic data for the following reaction or where I can find these data or any software or method to estimate them (even roughly) without doing any laboratory experiments?
CH4 + 0.5 O2 + C8H4O3 --> C9H8O4
methane + 0.5 oxygen + phthalic anhydride --> monomethyl phthalate...
The mixture of 32,5%wt urea with water is called AUS32 and it is liquid at standard conditions (1 bar, 298 K), but in Hysys this mixture is predicted as liquid-solid and a lot of urea doesn't dissolve in water (so it is in a solid phase).
How can I adjust the value of solubility of urea in...
How can I use a kinetic equation different from that provided by Aspen Hysys?
I need it in the form:
vr = A*exp(B*T)*C1*C2
where:
vr: reaction rate
A, B: experimental parameters
T: temperature
C1, C2: concentrations of reagents
