Hi,

 

I am currently working on a project where our equipment has to perform the following functions:

 

1. Reduce the pressure of the incoming natural gas from 15 bar to 5.5bar

2. remove all liquid content

3. Superheat the gas to 20°C super heat at the terminal point of our equipment

 

The incoming natural gas is available at a minimum of 10°C. After pressure reduction and liquid separation, the temperature can drop down to 4.5°C.

 

A heater is needed to superheat the gas to acheive the III objective but what it means by 20°C superheat? Does it mean 10°C + 20°C? or 4.5°C+20°C? dew point + 20°C? (the dew point I calculated is -22°C).

 

Regards,

Kashyap.

Kashyap,

 

As per the info you provided; it means 4.5 C+20 C. Indeed, appears 4.5 C to be the dew point of the outgoing natural gas from the separator at 5 barg...

Hi Fallah,

Thanks for the clarification.

 

I got the dew point calculation incorrect. I have checked it now and it is indeed 4°C (not -22°C)
