Chemical Tank BlanketingMarket Application Publication Background: It is common during industrial manufacturing to use a variety of chemicals at various points in the manufacturing process. These chemicals can be very sensitive to their environment and/or extremely dangerous. A nitrogen blanket is commonly used to ensure the chemical's integrity and minimize flammability or exptosivity concerns. This protection is necessary to preserve chemicals, maintain their useful Life and guarantee safety. • Price of our nitrogen is constant. Supplier Nitrogen is subject to pricing increases, rentaL agreements, hazmat fees, delivery surcharges, local & state taxes, etc. A nitrogen generator offers long term price stability. • Your cost increases relative to usage with bulk, dewar or cylinder nitrogen. Costs decrease as usage increases with a nitrogen generator. • Maintain chemical integrity with "inert" N2 Atmosphere. • Nitrogen has a very Low boiling point, and is continuously evaporating when supplied as Liquid in bulk or dewars. It can cost thousands of dollars if these gases are not recaptured. • A nitrogen generator eliminates the contracts required from bulk gas suppliers. No more automatic renewals, automatic increases or 1-year written notice for contract termination. • Ease of installation. Pipe in compressed air and pipe out Nitrogen. Contrast this with the installation re quirements for a bulk tank, including a concrete pad, fence and significant square footage. • Complete start up and testing procedure at the factory prior to delivery. • Very Little maintenance or monitoring required once system is up and running. Simple and straightforward operation. • Proven technology with numerous references available. Over 10,000 successfuL generator instaLLations. • Improve safety by minimizing flammability concern.

Application: Tank blanketing, or "padding", is the application of covering a chemical surface with nitrogen gas in order to protect a product from contamination, degradation, or chemical change. Introducing nitrogen, at a low pressure (typically less than 10 psig) and purity (typically 95-99.5%) will displace oxygen & water vapor, and maintaining this positive pressure prevents the ingression of ambient air (and oxygen). This nitrogen blanket is also used to balance tank volumes, minimizing any fluctuations due to changes in temperature, and to prevent a vacuum during discharge, averting any...
