摘要： An apparatus and method for simultaneous detection of N gas species through laser radiation attenuation techniques is disclosed. Each of the N species has a spectral absorption band. N laser sources operate at a wavelength λN in a spectral absorption band separated by the cutoff wavelength for single-mode transmission. Each laser source corresponds to a gas species and transmits radiation through an optical fiber constructed and arranged to provide single-mode transmission with minimal power loss.

摘要： The invention embodies methods and apparatuses to monitor and control the characteristics of a creping process. The method involves measuring optical properties of various points along a creped paper sheet and converting those measurements into characteristic defining data. The invention allows for determining the magnitude and distribution of crepe structures and their frequency and distribution. This allows for the generation of information that is accurate and is much more reliable than the coarse guessing that is currently used in the industry. Feeding this information to papermaking process equipment can result in increases in both quality and efficiency in papermaking.

摘要： A filtering system for monitoring fluid emissions from a process includes a plurality of filter assembly sections arranged in a parallel fluid flow manner with respect to each other so as to selectively receive a sample fluid (e.g., a sample gas) entering at an inlet of the system. Each filter assembly section includes a filter unit to filter particulate materials from a fluid flowing through the filter, first and second valves disposed at upstream and downstream locations of the filter unit, and a blowback flow path configured to selectively direct a cleaning fluid through the filter unit in a direction that opposes a direction in which the sample fluid flows through the filter unit. Each filter assembly section can be selectively isolated from other portions of the system so as to prevent the sample fluid from flowing through the filter assembly section while allowing a cleaning fluid to be delivered through the blowback flow path of the filter assembly section.

摘要： A method for indirect gas species monitoring based on measurements of selected gas species is disclosed. In situ absorption measurements of combustion species are used for process control and optimization. The gas species accessible by near or mid-IR techniques are limited to species that absorb in this spectral region. The absorption strength is selected to be strong enough for the required sensitivity and is selected to be isolated from neighboring absorption transitions. By coupling the gas measurement with a software sensor gas, species not accessible from the near or mid-IR absorption measurement can be predicted.
