Hello, I'm looking for chemical and physical properties of LNG. If anyone has some data regarding to it please share with me.

Hi,

Regarding vaporizer you should contact vendor familiar with this type of application , a link is attached .

Different set up are available , scroll the menu .

For properties , you are the one who is the supposed to know the material and composition , if not ask for a COA or specification .

note : Go to number 14 ( excel sheet)

 

 

To me you should prepare a spec sheet and submit to vendor .

 

Good luck

I'm calculating heat duty require to increase temp. Of LNG from -156 C to 0 C at 90 bar. At -156 C LNG is subcooled liquid it's boiling point is -82 C. I am tried using mCpdt + m(latent heat of vapor.) + mCpdt but i can't get heat duty 19.95 MW(actual heat duty as per datasheet) i got around 24 MW. Can anyone help me around this ?

I would follow Breizh's advice, in order to obtain accurate values you must know LNG composition, then accurate models such as for example GERG, will allow to calculate the properties.
