Patent ID: 8021612

Claim:
A system for monitoring and recording removal by a removal device of undesired constituents of a gas produced by a variable gas source, the system comprising: at least one gas sensor that senses characteristics of the gas and provides gas signals indicative of the characteristics of the gas before removal of undesired constituents from the gas; at least one removal device sensor that senses characteristics of the removal device as the removal device removes undesired constituents of the gas and provides removal signals indicative of operation of the removal device; a computing system comprising a computer readable medium storing software code for execution by the computing system in order to perform operations comprising accessing the gas signals and the removal signals; using the gas signals and the removal signals to develop a first record that corresponds to a quantity of undesired constituents removed from the gas; verifying data developed from the gas and removal signals; in response to determining that the data is faulty, permitting replacement of the faulty data with replacement data; and in response to receiving replacement data, developing a second record indicative of the replacement data as well as a rationale for selection of the replacement data.
