05/01/2020 Q: The last time we opened the fired heaters of the Platformer units, we noticed lots of dust accumulating on the tubes. We are looking for ways to externally clean the coils online.

Is there a way to do it with our internal resources?

If not, what are the companies that offer this service?

 
04/01/2020 Q: Why is the diameter of top and/or bottom of a VDU smaller than rest of the column?  
01/01/2020 Q: My question is related to an amine absorber used to strip out H2S from fuel gas or recycle gas. We know thatthe optimum temperature difference between gas and amine is to be maintained at 8 to 11 degrees Celsius.

1) Why does absorption decrease when delta T is below 8 & above 11? Please answer for individual case.
2) Moreover, does only delta T matter or do individual temperatures of gas and lean amine also matter for determining absorption efficiency ?
3) If individual temperatures do matter then what should be the optimum range of both?
 
01/01/2020 Q: It is planned to replace the inlet system of the Reformer in a Hydrogen Generation unit with upgraded metallurgy from SS 304 to SS 347. This upgradation is warranted due to an increase in inlet temperature of the Reformer feed (Prereformer is being introduced as a part of a revamp).
We would like to know if anyone has carried out such modification in your hydrogen generation unit.
Please share the details including precautions to be taken.
 
18/12/2019 Q: In our Hydrotreating & Hydrocracking Units, we do Catalyst Sulfiding in 2 stages: Low Temperature Sulfiding and High Temperature Sulfiding. What are the advantages of doing Sulfiding in 2 stages?
If we are treating heavier Feeds is 3 Stage Sulfiding used?
