Fractionation of Waste MDF by Steam Refining

Decontamination of laboratory microbiological waste by steam sterilization.

A steam sterilizer (autoclave) was tested to determine the operating parameters that affected sterilization of microbiological waste. Tests involved standardized loads (5, 10 ad 15 lb [ca. 2.27, 4.54, and 6.80 kg, respectively]) contaminated petri plates in autoclave bags placed in polypropylene or stainless steel containers. Thermal and biological data were obtained by using a digital potentio...

WASTE MINIMIZATION THROUGH IMPROVED PROCESS THERMODYNAMICS: CRUDE OIL FRACTIONATION by

Improve the Anaerobic Biodegradability by Copretreatment of Thermal Alkali and Steam Explosion of Lignocellulosic Waste

Effective alteration of the recalcitrance properties like crystallization of cellulose, lignin shield, and interlinking of lignocellulosic biomass is an ideal way to utilize the full-scale potential for biofuel production. This study exhibited three different pretreatment effects to enhance the digestibility of corn stover (CS) for methane production. In this context, steam explosion (SE) and t...

Continuous Steam Explosion of Wheat Straw by High Pressure Mechanical Refining System to Produce Sugars for Bioconversion

This study demonstrated the use of a pressurized mechanical refining system for the continuous steam explosion pretreatment of wheat straw. Wheat straw was first impregnated with either dilute acid (0.5% sulfuric acid) or water and then steam exploded in an Andritz pressurized refiner. The effect of a range of pretreatment conditions, including refining retention time and steam pressure/tempera...

Refining Abstract Machine Specifications of the Steam Boiler Control to Well Documented Executable Code

We use the steam boiler control speci cation problem to illustrate how the evolving algebra approach to the speci cation and the veri cation of complex systems can be exploited for a reliable and well documented development of executable, but formally inspectable and systematically modi able code. A hierarchy of stepwise re ned abstract machine models is developed, the ground version of which c...
