Certainly, most of the time, understanding the slug volume and its distribution over time is often just informative. The crucial aspect for designing the slug catcher or separator is the surge volume. However, there are instances when this information is needed for control system design or...
you are totally right when we need to size the slug catcher or determine the required surge size , we will calculate surge volume as the difference between the accumulated flow rate and drain rate .
but my question if i activated the slug tracking model in OLGA , many variables can be found...
thread798-156994
in OLGA software , in the TRENDDATA, PROFILEDATA output variables I can found many slug flow characteristics like slug length (LSLEXP) ,bubble length (LSBEXP), slug frequency but i can found slug volume , So how I can calculate the max liquid slug volume and average...
Thank you very much for your attempt to assist, although I might still be struggling to clarify my question.
Based on the findings of the Fire and Explosion Risk Assessment (FERA) study, different levels of radiation contours are associated with specific actions and considerations:
4.7 kW/m2...
After conducting a FERA (Fire and Explosion Risk Assessment) and QRA (Quantitative Risk Assessment) study, what is the the recommended risk level / radiation contour to placement / install of fire hydrants. and can we install fire hydrants within the 10^-4 (or 0.0001) risk level contour (ALARP...
Thank you for your response; it clarifies the reasons behind the variations in guidelines concerning the minimum separation distances required between crude oil tanks.
You are right when I checked NFPA 30 , I found many different tables, but I refer to class II liquids in ch. 12, actually, I don't have hand experience in NFPA, but I am surprised that the safe distance is minimal compared with GAPS Guidelines or CCPS (Center for Chemical Process Safety)...
is this correct According to NFPA 30, the recommended minimum separation distances between crude oil tanks are as follows:
For non-fire-resistance-rated tank construction:
For tanks with a capacity of more than 15,000 gallons (56,780 liters), the separation distance should be a minimum of 1.5...
The open and close drain system design is based on segregated system (The Open Non-Hazardous Drainage System is segregated from all other open or closed drain systems.), What is the API code which cover this point
is there a minimum inventory for the standalone tank to install the Lightning protection system, ex. if we have stand-alone storage tanks with 1000 bbl crude oil, should we install a Lightning protection system?
I totally agree with you, from an engineering judgment point of view, I think we can cover this area with fire extinguishers or portable fire fighting, but I wonder if the code cover this point and what is the minimum hydrocarbon inventory required to install fixed firefighting system
if I have a standalone crude oil storage tank in the desert with a capacity of 200 M3 , is it necessary to install a fixed fire fighting system or I can depend on portable fire fighting
actually the fixed cooling water system is only to protect the vessels from radiation and not for fire fighting , so if the distance between the vessel is very high and fire radiation does not affect the adjacent vessels structure, So we can depend on engineering judgment to evaluate the...
