SuperCap™ Announcement

Advanced Specialty Chemicals Co., LC (AdSpec) announces a new product to conveniently add extra Percap™ 355 ethyl mercaptan odorant to LP-Gas tanks. This new product is Supercap™, which is available in three sizes.

"Odor fade" is a problem that has plagued the LP-Gas industry for a number of years. It is well documented that new steel tanks can absorb, adsorb, or react with the ethyl mercaptan in LP-Gas, resulting in dangerously low levels of odorant. Used tanks exposed to air can also present a risk of odor fade. Installations with new piping may also contribute to odor fade.

Further, the odorant level in LP-Gas tanks naturally increases over the first few fill cycles. A Supercap can accelerate this natural accumulation, providing additional ethyl mercaptan at the beginning of new service for a tank or distribution system, or placing into service a used tank exposed to air.

Supercap is a unique design that simultaneously provides for ease of use, reliable operation, and reasonable cost. A Supercap container is placed in-line between a fill hose and an LP-Gas tank. Premeasured Percap 355 ethyl mercaptan is contained between two rupture disks, which burst during the normal transfer of LP-Gas into a tank.

Supercap increases the ethyl mercaptan concentration in a newly filled LP-Gas tank by 2 to 3 times normal odorant level, depending on the size of the tank. Supercap can also be used to add odorant to an LP-Gas tank suspected to be under-odorized.

Supercap is a compact unit. AdSpec's instructions, labeling, quality system, and Supercap design make the process simple and virtually foolproof.

The robust construction of the Supercap prevents leakage concerns and allows it to be torqued and treated as a typical pipe fitting.

Price of Supercap is $16.50 to $18.00 for each treatment (depending on tank size) plus shipping cost, with no deposit.

Empty containers may be disposed by returning to AdSpec in the original packaging, with return-shipping cost paid by AdSpec via convenient label.
