Does anyone of you have an experience with using crude oil for burners in steam boilers?
If so, what type of treatment for sulpher or others are conidered.
Thank you in advance

If I remember well, non of the cracking furnaces I have seen has burner handling FOP. Therefore, this doesn't mean that using FOP is not possible but you just need to check with vendors of burners and the furnaces technology provide to assure you no impact and feasible.
But I do see the...
For me, I did move into another company with similar business as previous one after 5 years.
The reason is that the previous company did not give me anything either promotion nor salary increase when I got my MS degree in same major (Chemical Eng) as part-time student for about 4.5 year...
Most of the DeC4 columns I have seen in about 4 ethylene plants do have reboiler with spare one.
The reason is that the base temperature causes the conversion of dienes to form polymerization material.
You can do the following:
- Add a spare reboiler if you are concerned about down time and do...
Does any one know the price of acetylene nowadays?
I'm evaluating a process (Absorption by DMF)for recovery of acetylene from cracked gas process of an ethylene plant?
Any help is highly appreciated

I think you need to have PSV if there is possibility of blockage of the HE equipment and where compressor PSVs are way from the blockage piping system.
If there is no isolation valves in between, using PSV of compressor would be possible if these safety valves can cover the max flow of the...
I think this is generic question as many factors fall on the selection of drain size of tanks.
Such factors are steam-out purposes, size of the tank, material stored..etc
I have seen various drain sizes as 2" for small tanks and 6" for large tanks
Hope this would help
cheers

Your question needs further elaboration
I got questions for you:
- Are there isolation valves causing blocked discharge of cold fluid
- If yes, then pumps are not of a problem as you will look for the trapped or blocked volume of liquid in the piping having isolation valves from both sides...
Sorry for making a question with this post but it is related to the same subject:
Which one velocity limit or pressure drop is the criteria of sizing of cooling water piping?

There are some companies specialized in such applications.
From experience, we did use a special contractor to do chemical cleaning of a system similar to system and the result was a mazy (time take is 2 days compared to 7 days we used to to take for cleaning)
You can look to the market where...
I think you need to have safety valve to protect the piping from damage that would lead to significant damage.
Sizing the safety valve depends on the gas properties (expansion coefficient and others) that will be subjected to constant heat flux when the line is blocked.
Hope this would help...
I have got a question by one of my friends as follows:
- In a heat exchanger, assuming the heating side on the shell side is constant, the question is that if the flow rate of the cold stream in the tube side is reduced, Is its outlet temperature is gone be high or low?
His answer to this...
Thanks for the contributions
Let me express my view as well:
Being a manager is the one of our goals in the future of most of us that we are looking for to get one day. Even it is early for some people to think about the managerial position but it gives the power and push to do the best in the...
