Thank you for your answer. Do you know any certificate useful for Junior roles?

What are the most important and recognised certificates related to Environmental Protection or Environmental Management for a Chemical Engineer?

Millisecond furnace with induced-draft fan, operating at around 800-870 ℃ and -0.5 mbar.

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?

Thank you again.

The vapour is bubbling through the liquid. Essentially, steam is generated by water.

Regarding the fooling factors, do you mean to check them in literature or experimentally?

Thank you.

Thank you very much. Please let me know if you have a source (e.g. a book) where I can have more information at this regard.

Thank for your answer, but it does not help me. I am looking for the method (equations, principles, theory) to apply to calculate the % of liquid entrained. I am not asking for the number. For example the Sauders-Brown equation can be used to assess if there is entrainment or not in a vessel...

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.

Thank you. Do you know which other substances are found in demineralized water and in which percentage?

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...
