Alternative Formulations and Packaging to Reduce use of by T.P. Nelson
By T.P. Nelson
This booklet describes replacement formulations and packaging suggestions for the relief or removing of chlorofluorocarbon (CFC) use as an aerosol propellant. Use of CFCs in particular different types of aerosols thought of "nonessential" used to be banned via the U.S. in 1978. contemporary renewed curiosity in additional decreasing around the globe construction and intake of CFCs, and different chemical compounds implicated within the depletion of the earth's stratospheric ozone layer, is chargeable for this research, which covers presently exempted and excluded CFC aerosol functions and their possible choices.

Glossary 21 Coalbed Methane – methane is generated during coal formation and is contained in the coal microstructure. Typical recovery entails pumping water out of the coal to allow the gas to escape. Methane is the principal component of natural gas. Coalbed methane can be added to natural gas pipelines without any special treatment. Coefficient of Haze (COH) – measurement of the quantity of dust and smoke in the atmosphere in a theoretical 1,000 linear feet of air. A COH of less than three is considered clean air and more than five is of some concern.

Glossary 37 possibility of adverse health effects based on the best scientific information available. Heats of Formation – the heats of formation for a reaction can be described as the total heat evolved when a given quantity of a substance is completely oxidized in an excess amount of oxygen, resulting in the formation of carbon dioxide, water and sulfur dioxide. The energy liberated during the formation of combustion products is known as the “heat of explosion”.
In vacuum purging, a vacuum is drawn on the vessel or reactor and then the vacuum is relieved with an inert gas. The procedure is repeated in cycles until a desired oxidant level is reached. In pressure inerting, the vessel or reactor is purged with an inert gas under pressure. The vessel or reactor vents to atmospheric pressure. The procedure is repeated unto a desired oxidant level us reached. Other forms of inerting are Sweep-through purging and Siphon purging (see separate definitions). Institutional Control (IC) – term used by EPA refereeing to nonengineering measures intended to affect human activities in such a way as to prevent or reduce exposure to hazardous substances.
