The steam pipes are sometimes prone to rupture, however. In , a gigantic steam explosion ripped through a street, killing three people and sending mud and debris several stories into the air. Alternative steam explosion techniques There are different alternatives to steam explosion treatment that have been used for pre-treatment of biomass for fermentation processes. Steam refining In conventional steam explosion processes the defibration is achieved by . Based on low pressure steam explosion technology, steam explosion integrated mechanical carding, steam explosion integrated super grinding and steam explosion integrated washing and alkali extraction are designed to realize stalk fractionation at different levels. Industry implementation of these technologies was also by: 1. Steam Explosion (SE) Steam Explosion (SE) is the most commonly used pretreatment of biomass and uses both physical and chemical methods to break the structure of the lignocellulosic material through an hydrothermal treatment. The biomass is treated with high pressure steam at high temperature for a short time, then it is rapidly depressurized andFile Size: 2MB.

Steam explosion is a rapidly developing technique for the fractionation and modification of lignocellulosics and for the extraction of industrial polysaccharides.
This book is a primary integrated presentation of the fundamental and technological aspects of this process, and provides an exhaustive discussion of its prospects for the future.
The main topics concern the kinetic and engineering.

A steam explosion is an explosion caused by violent boiling or flashing of water into steam, occurring when water is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals (as in a fuel–coolant interaction, or FCI, of molten nuclear-reactor fuel rods with water in a nuclear reactor core following a core-meltdown).
Steam explosion pretreatment has been examined in many studies for enhancing the enzymatic digestibility of lignocellulosic biomass and is currently the most common pretreatment method in commercial biorefineries.
The information available about the effect of the explosive decompression on the biochemical conversion is, however, very limited, and no studies prove that the latter is actually Cited by: On Jan explosion in Manhattan, New York City, sent a geyser of hot steam up from beneath a busy intersection, with a story-high shower of mud and flying debris raining down on the crowded streets of Midtown Manhattan.

Ejaz Ahmad, Kamal K. Pant, in Waste Biorefinery, Lignin From Steam Explosion Process. Steam explosion is an old process used for separating lignocellulosic biomass constituents for cellulose pulping in pulp and paper industries .In a typical steam explosion process, lignocellulosic biomass is exposed to high pressure (in the range of 35 bar) and moderate temperature, i.e., 1.
Introduction. Extraction by the steam explosion is a relatively new and developing method that in through self-evaporation results in the displacement of a large part of the volatile molecules in the plant (Meng and Ragauskas, ).This process is based on the volatility of fugacious compounds where, the raw materials are exposed to saturated vapor for a short period of time, which varies Cited by: 4.
