Abstract:
Methods and apparatuses, including computer program products, are described for measuring greenhouse gas. A calibration device receives a first sample of atmospheric gas from a first port exposed to the earth's atmosphere. The calibration device receives a second sample of atmospheric gas from a second port exposed to the earth's atmosphere. The calibration device routes the first sample and the second sample to a measurement device for greenhouse gas analysis. The measurement device determines a characteristic of a greenhouse gas present in at least one of the first sample and the second sample. The measurement device transmits data associated with the determined characteristic of the greenhouse gas to a computing device for determining sinks and sources of the gas.
Abstract:
Combustion tube (100,130,150) and method for combusting a sample to form combustion products for analysis. A primary combustion chamber (102) receives and combusts a sample to form first combustion products. A secondary combustion chamber (110) receives and combusts the first combustion products to form second combustion products. The secondary chamber is disposed around the primary chamber and comprises a plurality of—preferably, three—combustion compartments (112-116). Each successive compartment is disposed around the preceding compartment and defines a respective gas flow channel having an inlet opening (108,118,120) and an outlet opening (118,120,122) at opposite ends. Each successive gas flow channel shares its inlet opening with the outlet opening of the preceding channel. The plurality of combustion compartments define a substantially continuous gas flow conduit from the inlet opening of the innermost compartment to the outlet opening of the outermost compartment. Static gas mixers (132,134) may be employed to enhance mixing of the combustion products.
Abstract:
A device and method for removing particles, such as catalyst, from a chemical reactor tube by inserting a hollow tube body into the bottom end of a vertical tube, sealing between the hollow tube body and the vertical tube, blowing a gas through the hollow tube body into the bottom of the vertical tube, and vacuuming the top of the vertical tube while continuing to introduce gas into the bottom of the vertical tube.
Abstract:
A method that identifies the compounds contributing to a detected burnt odor from an air conditioner artificially reproduces the detected burnt odor, and prepares a corresponding burnt odor composition is provided. Through the analysis method of the present invention, the compounds that contribute to the detected burnt odor from an air conditioner are be identified and quantified. The detected burnt odor is reproduced from a combination of the compounds identified by the analysis method of the present invention. The reproduced burnt odor provides significant data required for development of an apparatus and a method for removing specific odor.

Abstract:
An embodiment of an apparatus is configured to determine a portion of a first signal according to a first algorithm, and to determine a portion of a second signal according to a second algorithm. For example, such an apparatus may include an analyzer and a determiner, where the analyzer is configured to indicate whether the portion of the first signal meets a first criterion and whether the portion of the second signal meets a second criterion, and where the determiner is configured to determine the portion of the first signal according to the first algorithm in response to the analyzer indicating that the portion of the first signal meets the first criterion, and to determine the portion of the second signal according to the second algorithm in response to the analyzer indicating that the portion of the second signal meets the second criterion.
Abstract:
An embodiment of an apparatus includes first and second component determiners configured to determine, respectively, first and second components of a signal, and includes an interpolator configured to interpolate a portion of the signal in response to the first and second components. For example, where the portion of the signal is empty, such an apparatus may include a periodic-component determiner, an aperiodic-component determiner, and an interpolator. The periodic-component determiner is configured to convert the signal into a frequency-domain transformed signal, and to convert the transformed signal into a time-domain periodic component of the signal, the periodic component having a periodic-component portion that corresponds to the empty portion of the signal. The aperiodic-component determiner is configured to determine, statistically, an aperiodic component of the signal, and the interpolator is configured to interpolate the empty portion of the signal in response to the periodic and aperiodic components of the signal.
Abstract:
A computer implemented, real-time, continuous, electromagnetic, spectroscopic, high sensitivity, digital method for analyzing a gas sample can include using an inline gas component analyzer to receive the gas sample. An electromagnetic beam generator can generate a beam to pass through a filter in a sample chamber and into the sample gas to form a sample wavelength. The sample wavelength can pass into an electromagnetic beam detector. A processor and data storage can be in communication with each component of the inline gas component analyzer for monitoring and controlling thereof. The processor can be in communication with client devices through a network for remote monitoring and controlling thereof. The inline gas component analyzer can be calibrated with a calibration gas sample.
