CHEMTANE 2 DATA SHEET

• What is CHEMTANE 2 concentrate? It is a trade secret formula of blended chemicals.
• Is CHEMTANE 2 patented? No. There are various obvious reasons, which can be discussed upon request.
• Mixing (blending) proportions are one (1) part CHEMTANE 2 concentrate to 199 parts propane/LPG.
• MSDS (Material Safety Data Sheet) on both CHEMTANE 2 gas and CHEMTANE 2 concentrate are available upon request.
• CHEMTANE 2 drums are filled to 50 gallons to allow for any possible expansion and contraction of the CHEMTANE 2 concentrate with temperature changes.
• The average total shipping weight is 340 pounds per shipping drum.
• Classification Numbers:

U.S. Department of Transportation chemical concentrate classification No. = UN 1993
U.S. Department of Transportation blended fuel gas classification No. = UN 1075

• The blending (mixing) process is very simple - no special equipment is required. Here are some examples:

The blending can be done in a LPG bobtail truck equipped with a pump and a meter. For example, to blend 1,000 gallons of CHEMTANE 2 fuel gas, you can add 5 gallons of CHEMTANE 2 concentrate in the truck and then add 995 gallons of LPG/propane (199:1ratio). You then simply mix the final cutting fuel one complete turn over by using the truck%u2019s pump and metering system. (Details can be furnished.)

Another method is to blend the final product in the 199:1 proportion in a bulk storage tank, using a recirculating pump to mix. From there you simply meter the blended finished product into a delivery truck for delivery to bulk customers, or into cylinders for cylinder delivery.

• The types of cylinders used by customers are those which are standard in the LPG/propane industry. In the U.S., 240 or 260 psi (pounds per square inch) cylinders are typically used. Standard cylinder sizes are 25 Lbs., 60 Lbs., 100 Lbs. and 420 Lbs.
• Instead of using an acetylene tip which will not work with CHEMTANE 2, Chemtane Energy, LLC. recommends using an industry standard 2-piece propane tip or natural gas tip. The two-piece tip is recessed, and it has more splines which are the openings from which the cutting fuel flows for better heat dispersion.
• With CHEMTANE 2, customers can use hoses, regulators and gauges which are standard in the industry and which are recommended by the manufacturer for the particular application of the cutting fuel. There are, however, certain qualities that make CHEMTANE 2 cutting fuel more versatile than acetylene as the brochure outlines in the %u201CProduct Features and Benefits%u201D section.

Other benefits, for example, specifically on the acetylene gauges, there is a red line at 15 psi, which is the maximum psi acetylene can be used safely. The reason for this is that there is a danger of drawing acetone from the acetylene cylinder above 15 psi.

Although a pressure setting of, say 5 psi, might be recommended for cutting 1-inch steel plate with CHEMTANE 2, you can operate with a much higher psi if required for a particular application. Acetylene must not be used at depths greater than approximately 20 ft., because its maximum safe operating pressure is 15 psi. With CHEMTANE 2, you can cut at depths to which divers can descend and perform satisfactorily, using pressures up to fuel gauge limits or tank pressure.

• In addition to reduced product and labor costs, there are a couple of other factors which should be considered when analyzing the cost savings associated with CHEMTANE 2:

With acetylene, up to 20% is trapped in the cylinder and can thus never be used. This factor becomes important when comparing cylinder quantities of acetylene vs. CHEMTANE 2.

Another factor to consider is production. Acetylene cuts 1-inch steel at 13-14 inches per minute. CHEMTANE 2 cuts 1-inch steel at 20 inches per minute.

Cutting with CHEMTANE 2 consumes approximately the same oxygen when performing the same task as acetylene, but CHEMTANE 2 consumes 42% less oxygen than when that same cutting task is performed with propane.
