Dear Gentlemen,
I would like to ask one question. We are replacing gus ducts on some of the gas lines in sulfuric acid plant. Contractor firm started to bring material to site but as a process engineer, it looked odd to me that manufacturer made welding on the middle of the knots of every...
Dear Collegues,
We ended up applying partial rubber coating where the most of the thinning down of metal occurs. (We applied to 5 trucks and I will keep watching to see how it will be)
Thanks for your efforts and sincere support.
It looks like we will brick line both acid preheating vessel and reactor.
I need to find out what kind of heat exchanger we need to use for preheating H2SO4 up tp 190 C while cooling the NaHSO4 melt down.
Dear Gents,
Thanks for your replies. As an update,
- We are advised to install vacuum valve onto the tankers to stop the effect stems from humidity.
Regarding teflon coating, do you think it is flexible enough when subject to vibration due to movements of the trucks?
Dear fellows,
I am working in a chemical handling company. We are mainly transporting H2SO4 and HCl by chemical tanker trucks. Recently, we measure the thickness of the tankers, we notified that there is quite noticeable thinning after using the tankers for 6 years. (The material used for...
Dear Colleagues,
I would like to design a continuous reactor for the production of Sodium Bisulfate melt with immersion burner which will keep the reactor temperature over 240 C, continuously agitated and sulfuric acid (1700 kg/hr 98% conc. 1.8 gr/cm3 density) and sodium chlorine (1000 kg/h)...
Dear Colleagues,
In one part of the plant (phosphoric acid) I am working as a process engineer, we have 4 CSTR crystallization tanks in series and the slurry is flowing as overflow from one to another and from 4th tank to filtration section by slurry pump. For a long time, we have been having...
