There are many compressor stations along long-distance natural gas pipelines. Natural gas can be transported using different boot programs and import pressures, combined with temperature control parameters. Moreover, different transport methods have correspondingly different energy consumptions. At present, the operating parameters of many pipelines are determined empirically by dispatchers, re...

Gas flaring is a combustion device to burn associated, unwanted or excess gases and liquids released during normal or unplanned over-pressuring operation in many industrial processes, such as oil-gas extraction, refineries, chemical plants, coal industry and landfills. Gas flaring is a significant source of greenhouse gases emissions. It also generates noise, heat and provided large areas uninh...

Title of Document: Efficiency Enhancement for Natural Gas Liquefaction with CO2 Capture and Sequestration through Cycles Innovation and Process Optimization Abdullah Alabdulkarem, Doctor of Philosophy, 2014 Directed By: Professor, Reinhard Radermacher, Mechanical Engineering Liquefied natural gas (LNG) plants are energy intensive. As a result, the power plants operating these LNG plants emit hi...

Reduction of energy consumption and CO2 emissions are recognized as important issues in today’s world. In addition, oil and gas companies are looking for ways to increase their capacity and maximize system uptime in order to meet the global energy demand. To realize these goals, oil and gas facilities are looking for 261 STUDY OF LARGE VSI DRIVE SYSTEM FOR OIL AND GAS INDUSTRY

Selectivity and low power consumption are major challenges in the development of sophisticated gas sensor devices. A sensor system is presented that unifies selective sensor-gas interactions and energy-harvesting properties, using defined organic-inorganic hybrid materials. Simulations of chemical-binding interactions and the consequent electronic surface modulation give more insight into the c...

OBJECTIVE To describe the kinetics of metabolic gas exchange at the onset and offset of low level, constant work exercise in patients with chronic heart failure. SETTING Tertiary referral centre for cardiology. PATIENTS 10 patients with chronic heart failure and 10 age matched controls. METHODS Each subject undertook maximum incremental exercise testing with metabolic gas exchange measure...

For modern Gas sensors, high sensitivity and low power are expected. This paper discusses design, simulation and fabrication of new Micromachined Thermal Converters (MTCs) based on GaAs developed for Gas sensors. Metal oxide gas sensors generally work in high temperature mode that is required for chemical reactions to be performed between molecules of the specified gas and the surface of sensin...
