Process and plant engineers responsible for green energy production, co-generation electric power, pollution monitoring or environmental compliance will find the new Green Energy Gas Flow Measurement Application Guide from Fluid Components International (FCI) as a suitable solution to meet the challenges of precise air/gas flow measurement in clean, wet or dirty hydrocarbon-based gases. The Green Energy Gas Flow Measurement Guides are available from AMS Instrumentation & Calibration .
With over 40 years experience in flow and level measurement, FCI's flow meters and flow switches feature a highly reliable no-moving parts design with no orifices to plug or foul. They are utilised in traditional and alternative energy process control, pollution monitoring and environmental management applications. FCI's instruments provide data for regulatory compliance and carbon trading as well as greenhouse gas reduction incentives and credits.
Thermal dispersion technology mass flow meters and flow switches from FCI are designed for operation in rugged, wet and dirty gas environments. They measure the mixed composition gases in explosive environments over a wide range from exceptionally low-flows to high pressure environments with rapid turndowns. Their exceptional performance over a long life with virtually no maintenance ensures accuracy, while eliminating expensive field technician time and costly re-engineering of critical plant processes.
Ethanol production is a distillation process that requires boilers whose efficiency is optimised with the control of their air-to-fuel ratio using thermal type flow meters. In addition to producing ethanol, this process generates greenhouse gases or volatile organic compounds (VOC's) that must be monitored. The precise measurement of fuel gas, air and waste gases flowing in small to large lines under variable temperatures, flow rates and less than optimum flow profiles is essential for efficient ethanol production with the lowest carbon pollution footprint.
The recovery of methane (CH4) gas from coal mining operations is creating a new energy resource. The three major sources of coal mine methane (CMM) are degasification systems (drainage type), both pre-mine and gob, ventilation air (VAM) and abandoned or closed mines. Thermal dispersion type flow meters are suitable for operations in co-gen engines or methane oxidiser systems as well as for providing data for incentive credits.
Decomposing waste on dairy cow farms, cattle feed lots, poultry ranches and other livestock operations produce extensive amounts of biogas that can be harvested as fuel gases. Rather than emitting these dangerous CH4 and other greenhouse gases, operators are capturing this waste gas to power plant operations and/or export to the public power grid. Accurate thermal technology air/gas flow meters ensure the efficiency of such operations.
Landfill gases are a mixture of CH4 and carbon dioxide (CO2) with trace gases that also include N2, O2 and others. Thermal instruments accurately measure gas flow for environmental reporting to regulatory agencies. These gases also can be supplied for co-generation electric power, which can be used for power needs at the landfill site as well as the public power grid.
Organic waste from fruit and vegetable peelings or meat preparation in the food and beverage processing industries is digested under anaerobic conditions in a reactor tank or fermentation tower. The gas output is a mixture of CH4, CO2, water and trace amounts of H2S that is measured with thermal instruments. The gas mixture is either flared off or supplied to a plant electric co-generation station for plant energy purposes or exported to the public power grid.
In municipal waste treatment plants, anaerobic digesters produce biogas measured with thermal flow meters. The biogas is a dangerous combination of CH4 and CO2, with smaller percentages of H2S and other gases. The gas flow varies widely based on fluctuating plant demands and seasonal variations in temperature and humidity.
