Abstract: The present invention is a method and apparatus for effectuating commerce in claimant-driven individual pollution credits which allows gas utility consumers to claim pollution credit when reducing their pollution levels while employing energy efficiency measures, which has value. Such reduced pollution credit is given value by a third-party, thus, individuals, government agencies and related parties, working in concert with a third-party identify the need, establish ownership, calculate the pollution credit value, and create a new market that has economic value and environmental benefit.

Abstract: A detector system and method are described for accurately indicating filter capacity of a filter assembly positioned within the piping network owned by the end user, includes the steps of: (a) introducing the natural gas stream to a filter selected from a group that includes at least activated charcoal and impingement adsorbing and absorbing media whereby natural gas contaminants concentrated in the gas stream at sufficient levels to be a detection threat by aperiodic loading of such network in which contaminants become clumped into packets due to dampening effects of the compressor-driven equipment and multiple customer outlet usage that add to aperiodic loading of the natural gas stream coupled with surprising longevity of the in situ contaminant, is filtered from the gas stream and captured, (b) passing an unfiltered sample of natural gas stream and a filtered sample of such stream to the detector system of the invention wherein capacity of the filter assembly located within the end user-customer's piping

Abstract: A detector system and method for accurately indicating over- and under pressurization conditions within the piping network owned by the end user, includes the steps of: (a) introducing the natural gas stream to a filter selected from a group that includes at least activated charcoal and impingement adsorbing and absorbing media whereby natural gas contaminants concentrated in the gas stream at sufficient levels to be a detection threat by aperiodic loading of such network in which contaminants become clumped into packets due to dampening effects of the compressor-driven equipment and multiple customer outlet usage that add to aperiodic loading of the natural gas stream coupled with surprising longevity of the in situ contaminant, is filtered from the gas stream and captured, (b) passing filtered sample of natural gas and a sample of ambient air to a pair of identical systems excepting the set point level of each is formulated to indicated the occurrence of either an over-pressurization condition or of an unde

Abstract: Temperature of the gas stream entering the end user's internal piping system has been found to be fairly stable (at about 50 degree F.) but still variable while the temperature of the end user's internal piping system (irrespective of total length) has been found to vary as a function of the ambient temperature exterior of the end user's internal piping system. Each of such temperatures can be used in association with a differential pressure leakage detection system that uses a piezoresistive pressure sensor which measures differential pressures between the natural gas and ambient air both entering the sensor to provide a pair of output signals with the difference between these signals being related to the occurrence of small leakage of natural gas within the internal piping network of the end-user, such flow being normalized so that any such flow is due only to leakage.

Abstract: A method of filtering a natural gas stream, at the end user's home, business or the like, in which at least a single gas appliance is located, is described in which natural gas odorants have been concentrated in the stream at sufficient levels to be a significant health hazard and/or an adverse environmental threat, such method comprising the steps of: (a) introducing the stream to a filter selected from a group that includes at least activated charcoal and/or impingement adsorbing media wherein in the odorant in the gas stream at sufficient levels to be a significant health hazard and/or an adverse environmental threat due to aperiodic loading of the network occurring as a result of dampening effects of compressor-driven equipment and multiple customer outlet usage causing the ordorant to become clumped into packets, is filtered from the gas stream and captured irrespective of mode of transport, (b) passing the filtered natural gas stream to the end user's gas appliance wherein safe use of the energy associa
