Gents, Thank you very much for yoyr answers. The model showing back flow in the main flare stack after hot relief is stopped and system being cooled down due to a rainstorm.

And also if this is a realistic scenario, how to solve this problem? Thanks

Gents, I am calculating the emergency purge rate for the HP flare system which has two stacks - main for the small reliefs and emergency for the large reliefs. Calculation is done using dynamic simulation for the case when the emergency stack is open and main is closed. The flow which we...

Dear sirs, Now I am working on the project where we are installing a line to transport a water which can contain significant quantity of sand. Main purpose is to size this line diameter small enough to have the actual fluid velocity less that terminal velocity to avoid the sedimentation of...

Dear all, Currently I am working on the project, where we installed two dissimilar check valves to protect system from the back flow. One of our concerns now is how to do a regular check of these valves without disconnecting them. I would appreciate if you could advice me a standard which I can...

Dear all, Now I am working on the project which involves blowodown calcualtion using HYSYS utility. We need to blow down a small inventory (piping spool with volume of 0.3 m. cub)and concerned about the minimum temperature upstream of the restriction orifice because the design temperature of...

Thanks to all for your help!

Dear Colleagues, We are looking for suitable washable filters to reduce Total Dissolved Solids (TSS) in Produced Water from 160 mg/l to 20 mg/l. The majority of particles are less than 20 microns. The filters should preferably occupy small space and require a minimum amount of washing water as...

Thank you very much for all your comments they seem very useful.

Dear all, Could you please help me with the following query: Now I am doing the blowdown calculations for the gas injection manifold. It is 16" Manifold with 10 meters line with enlarger at the end (increasing line size to 6") and blowdown orifice on the 6" line. Is it possible to use the...

Hello, Happy new year to all!!! we are going to replace the existing lube oil in our compressor with a higher grade (150 vs. 100). The lube oil circulates between crankcase and lube oil cooler (air h-xchanger). Basically, we want the lube oil that leaves the crankcase to have higher...

EmmanuelTop, Thank you very much for your help. But I need some type of standard to refer it in my calculations. Thanks.

Hello sirs, I am working on the project which covers the modification of the existing produced water tank. Recently I have been asked to verify the size of the vent line, which is located on the overflow line of that tank. The main purpose of this line is to help to avoid the "syphon effect"...

Sirs, I would appreciate if you can help me with the following issue: Now I looking for Distance learning course to get the MSc degree in the chemical engineering. I am interested in the Process design for Oil and Gas industry. I have already got this degree but unfortinately my university is...

Hello sirs, Now I am working on modification of ground flare system, which includes both HP and LP flare headers. So could anybody help me to find a criteria or at list to advice a standard for the setting of flare staging valve pressure? Thanks in advance.
