Thanks for the reply.
We burn lean refinery gas in the our burner. It is pretty clean fuel equivalent to natural gas. Could this fuel cause van / Na / nox ash deposit.
Can sulphidation occur in 9 Chrome Metal. Does 9 Chrome metal has copper in it.
We are seeing some flakes like deposit on the furnace tubes. These flakes glow in bright off white color when the furnace is running. I believe it might a product of sulphidation. Our tubes are 9 chrome.
Thanks...
Does any one have experienced that improper cleaning of the scale deposit from the tubeside of an exchanger resulted in a pressure drop higher than it was before cleaning ?
Just wanted to confirm if a simple ratio ( old delta p / new delta p ) can be used to prorate the pressure drop in a line for a new flowrate.
new dp = ( Q2 / Q1 ) * old dp.
Thanks
We've checked GPSA and API data books and the net, and can't find net and gross heating values for the following components:
methy mercaptan
ethyl mercaptan
n-propyl mercaptan
2-methyl-2-pentene

Wonderful thank you very much.
It really helped me in clearing up my confusion. Just out of criusoity , I am asking is there any special course, one has to take to learn these softwares or any chemical engg. with books can learn this on his own. I am working as Co-op student in a refinery and in...
Thank you very much. I really found very helpful material on this web site and moreover GPSA link is also helping me out in understanding Hydrates formation.
Could you please specify more about ProII & Hysys? If I am not wrong these are simulation software , how they help in predicting hydrates...
Does anybody have any informatin about the problems that gas hydrates can cause in natural gas pipelines and under what circumstances these hydrates are formed.
What precautionary control measures have to be implemented to off set their effects. We are using natrual gas as a commodity ( it is...
Can any body direct me how to calcualte N2O emission from the combustion of fossil fuels.
N2O is one of the Green House Gases.
Fuels we are using are
Coke
Gas Oil
Diesel
Kero
Natural Gas
Refinery Gas
Thanks.

Hi Steven Van ,
I really liked your example of the bolier ( fired on excess gas ) but on the same token Sandeep 's option of liquifying excess refinery gases or extracting CH4 or propane out of it is also good option to minimise flaring( by such an extraction you reduce the volume of your...
Hi Guys ,
On my request one of my company's well experienced manager replied to this flaring issue as follows :
This feedback is from Coleen West ( Manager Site Wide Energy & GHG Coordination & Management )

Hi DKF,
Flaring in refineries is practised as a last easy avaialble option in emergencies. In refinery most of the processes are interconnected , with or without intermediate storage available. For example refinery / off gases from bitumen coker or distillation towers have to be used in either...
Hi,
Can anybody guide me in calculating Energy Intensity or Energy index of a refinery , actually our operation is consist of 3 main processes ,
1. Exploration / production
2. Extraction / Conditioning of Crude
3. Refining
our site wide energy sources are Coke , Refinery Gases, Natural Gas...
Hi ,
Can anybody help me in identifying the GHG emission reduction opportunities in any Petroleum Refinery.
And any basis of Calculating and REDUCING the amount of CO2 emitted from different processes of Steam Generation / H2 generation and etc.
