Dear all,

Any of you have experience using nitrogen blanketing to reduce emissions of internal floating roof tanks? I have been asked if it is possible use nitrogen under pressure in the space between the floating cover and the fixed roof in order to reduce emissions but I have never seen it and I am not sure that a floating cover can work under pressure. As far as I know the nitrogen blanketing for internal floating roof tanks aims to avoid the flammable mixtures inside te tank.

Thank you for any help.

Hi,

Look into API 650 Apendix F. You will find venting requirement of internal floating roof tank.

Thanks.
