[MW:15081] RE: 15076] API 580 (Nov 2009) - RBI: Para 14.9(d)

Ali,

 

The statement is self-explanatory – you didn’t understand it. What it means is that liquid phase imposes lesser consequences than gas phase. In molecular theory, gas molecules travel faster, occupy more space, and exert more pressure than liquid molecules. Therefore, gas leaks are more explosive than liquid leaks.

 

Hope this help.

Dear All,

 

I was going through the contents of RBI and am confused with the interpretation and reasoning for the following statement

 

"Example of reducing the magnitude of consequence: substitute gas phase technology for liquid phase"

 

What I interpret from this is that the gas phase has lesser consequence than the liquid phase and its better to work with gas phase.

 

But why? I collect that gas leaks lead to explosions while liquid leaks are still leaks. For example during pressure tests we take more precautions when using air than with water.

 

Please pour in some logic to this topic.

 

 

Regards,

 

Muhammad Ali
