• The use of adsorption and zeolite filters in Halozone Recy c l i n g
Incorporated's patent-protected (proprietary) Blue Bottle® technology is
helping the refrigeration and air conditioning industry meet Montreal
Protocol targets and local government regulations.
The key to the Blue Bottle technology is a synthetic zeolite (Halozite)
which selectively adsorbs halogenated hydrocarbons. Halozone's Blue
Bottle system eliminates virtually all emissions of refrigerant in a wide
variety of processes including routine purging of low pressure centrifugal
chillers and during service and decommissioning of air conditioning and
refrigeration equipment. Adsorption is a phenomenon where molecules
concentrate on a solid surface without any chemical change. Adsorption
takes place due to unsatisfied forces in a surface that attract and hold the
molecules on the surface. The Halozite inside the Blue Bottle cylinder acts
as a selective molecular sieve, and therefore only refrigerant is captured. No
other compounds adhere to the Halozite. Refrigerant gases are captured at
ambient temperatures, and the capture occurs under atmospheric pressure;
that important feature eliminates the need for special, p re s s u r i z e d
transportation vehicles and licensing.
Once a Blue Bottle cylinder has been charged with refrigerant, it is sent to
Halozone's central reclamation facility outside of Toronto, where the
captured refrigerant is reclaimed without chemical breakdown. These
reclaimed refrigerants are returned to industry standard specifications
(ARI-700-93) before being transferred to certified storage containers. The
Halozite adsorbent is regenerated and the Blue Bottle cylinders are sent
back out to the field for reuse.
By reclaiming CFCs, Halozone's technology allows users to operate their
refrigeration and air conditioning equipment until the end of its useful life,
thus deferring the expense of conversion to alternative chemicals or cooling
processes.
• On-site applications are turn-key recovery systems that effectively capture,
recover and reprocess dilute emissions in industrial settings. In some cases,
the end product is returned directly to the industrial process without further
purification. These industrial uses of halogenated hydrocarbons include
CFCs used as solvents and cleaners, the fumigation gas — methyl bromide,
and the fire retardant — halon.
• The Thermco Terminator technology can improve the efficiency of the
condenser and evaporator in certain commercial refrigeration systems,
permitting lower energy consumption by the compressor motor.
