Pollution Prevention through Process Integration: Systematic by Mahmoud M. El-Halwagi

By Mahmoud M. El-Halwagi

The environmental impression of business waste is likely one of the such a lot critical demanding situations dealing with the chemical procedure industries. From a spotlight on end-of-pipe therapy within the Seventies, chemical brands have increasinglyimplemented pollutants prevention guidelines within which pollution are mitigated on the resource or separated and recovered after which reused or sold.

This booklet is the 1st to offer systematic options for low cost toxins prevention, changing what has been an paintings that will depend on adventure and subjective opinion right into a technology rooted in primary engineering ideas and approach integration. step by step techniques are offered which are largely acceptable to the chemical, petrochemical, petroleum, pharmaceutical, nutrients, and metals industries.

Various degrees of class starting from graphical tips on how to algebraic methods and mathematical optimization, a number of functions and case stories, and built-in software program for optimizing waste restoration structures make Pollution Prevention via strategy Integration: Systematic layout Tools a needs to learn for a large spectrum of working towards engineers, environmental scientists, plant managers, complicated undergraduate and graduate scholars, and researchers within the parts of pollutants prevention andprocess integration.

  • Allows the reader to set up pollution-prevention pursuits for a procedure after which advance implementable, low-priced solutions
  • Contains step by step techniques that may be utilized to environmental difficulties in a wide selection of method industries
  • Integrates toxins prevention with different method objectives
  • Author is the world over well-known for pioneering paintings in constructing mass integration technological know-how and technology

Recyclingtechnik: Fachbuch für Lehre und Praxis (German Edition)

Das Recycling von Altgeräten, Werkstoffen und anderen Materialien leistet einen wesentlichen Beitrag zur Ressourcenschonung, Schadstoffbeseitigung und Energieeinsparung sowie zur Reduzierung von Deponievolumen. Die einsetzbare Recyclingtechnik ist dabei eine grundlegende Voraussetzung für die wirtschaftliche Realisierung der Prozesse.

Solid Waste Management in the World's Cities: Water and Sanitation in the World's Cities 2010

In our speedily urbanizing international society, reliable waste administration should be a key problem dealing with the entire world's towns. sturdy Waste administration within the World's towns offers a clean viewpoint and new facts on one of many greatest matters in city improvement. utilizing the framework of built-in Sustainable Waste administration (ISWM), the record brings jointly unheard of examine from 22 towns throughout six continents.

Analysis and Fate of Surfactants in the Aquatic Environment, Volume 40 (Comprehensive Analytical Chemistry)

An figuring out of the destiny and behavior of natural chemical substances, corresponding to surfactants, within the surroundings is a prerequisite for the sustainable improvement of human healthiness and ecosystems. As surfactants are being produced in large quantities, you will need to have an in depth wisdom approximately their lifetime within the surroundings, their biodegradability in wastewater remedy crops and in ordinary waters, and their ecotoxicity.

Amine). These resins can be used to eliminate various species from wastewater, such as dissolved metals, sulfides, cyanides, amines, phenols, and halides. Leaching, which is the selective solution of specific constituents of a solid mixture when brought in contact with a liquid solvent. It is particularly useful in separating metals from solid matrices and sludge. Stripping, which corresponds to the desorption of relatively volatile compounds from liquid or solid streams using a gaseous MSA. Examples include the recovery of volatile organic compounds from aqueous wastes using air, the removal of ammonia from the wastewater of fertilizer plants using steam, and the regeneration of spent activated carbon using steam or nitrogen.

Such contact can be accomplished by using various types of mass-exchange units and internals. In particular, there are two primary categories of mass-exchange devices: multistage and differential contactors. In a multistage mass exchanger, each stage provides intimate contact between the rich and the lean phases followed by phase separation.
