As biofuel production becomes more and more widespread, the issue of safety, - especially in terms of the handling, transporting, and storage of methanol - becomes more of a concern for experts to consider.
When methanol is stored in tanks, it has a tendency to form vapors that are extremely flammable. In an effort to prevent the formation of these vapors, Nitrogen gas is introduced as an inert gas to take up the extra space in the tank.
The process of using Nitrogen in atmosphere blanketing, or tank blanketing, for methanol gas increases the safety factor of storage and transport. Nitrogen is a clean, dry, inert gas that is nonflammable and noncombustible. Nitrogen is introduced to the tank to eliminate the presence of Oxygen, an essential factor for combustion.

Research with Nitrogen blanketing and biofuel production has shown that, in addition to preventing hazardous fires, the presence of Nitrogen in methanol, biodiesel, and soybean oil storage tanks also reduces oxidation and other factors that affect the quality of the biofuel. So the process of Nitrogen blanketing not only increases the safety factor of storing and transporting biofuel, it also provides a high quality product.
Further contributing to the safety factor is the use of a Nitrogen Generator for providing high purity Nitrogen gas on-demand for the tank blanketing process. A Nitrogen Generator eliminates the need for dealing with high pressure N2 cylinders while safely and reliably providing the purity and flow necessary to maintain the proper inert atmosphere for blanketing applications.
Use of a Nitrogen Generator on-site is also a cost effective solution to tank blanketing for biofuel production:
- eliminate contracts with gas suppliers,
- generate as much or as little N2 gas as necessary at any given time,
- maintain a constant, steady supply without worrying about running out, and
- eliminate the cost of gas lost to evaporation during transportation and storage.
