tank blanketing
(OP)
Hi..
I need to study the tank blanqueting process so have a few quetions about it. what's the principal reason this process is instaled?Reduce the emissions?
How this proces really works?
I'd really appreciate your help

RE: tank blanketing
The actual scheme to blanket the tank is dependent on the design pressure of the tank and the method used to control/dispose of the vented contaminated waste gas during filling or tank breathing.
I hope this helps

RE: tank blanketing
how it's the cost of a blanked instalation? i asume it's lower tan a VRU instalation and equiment.
i hope you can help me..
thanks!

Fisher sells the ACE 95 series tank blanket regulators. Several threads have discussed tank blanketing on this site. Do a search for "tank blanket". If that brings no results, my normal response, put the same words in an advanced search to bring up several pages.
RE: tank blanketing
For instance if the blanket pressure is 20 and the vapor pressure of the liquid product is 6, the maximum concentration of the vapor space will be approximately 6/20 or 30%. The units on the pressure do not matter as long as they are the same. If you can get the blanket pressure high enough not to exceed the design pressure of the tank and that pressure is sufficiently high to reduce the maximum vapor concentration allowed by air pollution regulations, then blanketing may be an option.
As far as relative costs of VRU vs. blanketing, there is no way to answer than without knowing the product, product cost, blanketing gas, blanketing gas cost, vapor flow rates, tank design pressures, etc. That would require more work than this free forum allows.

A blanket of natural gas, with a flare will increase CO2, H2O and so forth in emissions, but will eliminate stuff like H2S, VOC's, etc...
A natural gas blanket with a VRU can provide the same protection and the gas can be recompressed for boiler/heating purposes (I wouldn't re-use it as blanket because of potential O2 contamination). $$$$ would be the determining factor here.
Inert blankets, such as N2 are used when the product is sensible to other types of gases.
A blanket can reduce noxious emissions, provide fire prevention, protect a product that could deteriorate if exposed to air, etc... There are several uses
