Hi

 

I am dealing with propane vaporiser system in which the propane comes in liquid form from a buffer tank and is pumped into a propane vaporiser .After the vaporiser the vapor propane goes into a fuel gas system .

 

During startup and shut down , nitrogen (which is usually closed in normal operation )is allowed to pass through the system to pressurise it.

 

My question is if during normal operation ,the nitrogen is inadvertently released into the line which contains propane,will slug form occur? My understanding of slug flow is inadequate,so please help me out with the possible consequences . I think it will lead to an increase pressure in the system.

 

 

I also have doubts regarding the Joule Thomson effect .Is it possible in this system,i.e. can an external leak in the vaporiser or any pipeline cause the J-T effect, (because the suddenly fluid changes from high pressure to low pressure) ,or is the Joule -Thomson effect valid only the fluid passes through an expansion valve?
