The reported experimental results involve fully condensing flows of pure FC-72 vapor on a horizontal condensing surface (316 stainless steel) which is the bottom surface (wall) of a rectangular cross-section duct of 2 mm height, 15 mm width, and 1 m length. The sides and top of the duct are made of clear plastic. The experimental system in which this condenser is used is able to control steadyi...

This study was conducted to investigate thermal aspects of municipal solid waste landfills as a function of operational conditions and climatic region. Spatial and temporal distributions of waste temperatures were determined at four landfills located in North America �Michigan, New Mexico, Alaska, and British Columbia�. Temperatures of wastes at shallow depths �extending to 6 to 8 m depth� and ...

The incineration of municipal waste under existing legislative and operational boundary conditions is a very complex process. An optimisation in the emissions is possible by a splitting up of the combustion air into primary and secondary air. The mixing of the secondary air into the furnace is the most important feature in order to reach uniform oxygen, temperature and velocity distributions. T...

This paper deals with the design of mixed thermally coupled-heat integrated distillation sequences. The approach considers from conventional columns (each distillation column with a condenser and a reboiler) to fully thermally coupled systems (only one reboiler and one condenser in the entire system). A discussion about superstructure generation and the convenience of using a representation bas...

The article describes the technological scheme and principle of operation a pyrolysis bioenergy plant (PBEP) with recuperative heat exchanger, which simultaneously provides hot water, gaseous liquid biofuels to consumer. results mathematical modeling exchange processes in condenser are presented order identify optimal thermal parameters for cooling biomass steam. A model balance “mixing-displac...

This work presents a reactive distillation column for the catalytic disproportionation of trichlorosilane to silane which includes three consecutive reversible reactions. This reaction system is however characterized by a large distinction in the boiling points of the components, which make the reactive distillation extremely favored. Nevertheless, the normal reactive distillation column posses...
