The reduction of greenhouse gas emissions using various thermal systems in a landfill site
In this paper, the Greenhouse Gas (GHG) emissions from an uncontrolled landfill site filled with Municipal Solid Waste (MSW) are compared with those from controlled sites in which collected Landfill Gases (LFG) are utilised by various technologies. These technologies include flaring, conventional electricity generation technologies such as Internal Combustion Engine (ICE) and Gas Turbine (GT) and ...

Cost allocation in cogeneration power–desalination plant utilising gas/steam combined cycle (GTCC) in Kuwait
Gas turbine combined cycle (GTCC) plants have high overall thermal efficiency, and are used for large base–load power plants (PPs) to produce electric power (EP) and desalted seawater (DW) at the lowest cost per units of EP and DW. Allocating the cost of each product (EP and DW) is the subject of this paper. Energy and exergy analyses as well as the power loss due to supplying steam to desalting ...

Thermal Mass Flow Meters Improve Efficiency in Wastewater Treatment Plants
Every municipality throughout the country has a wastewater treatment plant to safely treat water that enters back into our environment. This doesn’t mean they are immune to problems. One of the biggest problems for US wastewater treatment plants is the aging infrastructure with an estimated 180 billion dollars needed to repair many wastewater plants. A close second is the energy needed to ...

Thermal protection - WWTF gets ahead of the curve with thermal mass flowmeters
For the Santa Cruz Wastewater Treatment Facility (WWTF), dependability matters. Since 1989, this state-of-the-art WWTF, nestled in a shallow canyon in the coastal city of Santa Cruz, Calif., has been leading the way for renewable energy programs and environmental protection in the West. Santa Cruz WWTF generates its own electric power by using internal combustion engines that burn a mixture of ...
