Basic Principles and Calculations in Chemical Engineering

niques used in the field of chemical engineering as well as biological, petro-leum, and environmental engineering. Although the range of subjects deemed to be in the province of chemical engineering has broadened over the last twenty years, the basic principles of this field of study remain the same.

Fundamentals of Chemical Reactor Theory1

Chemical kinetics and reactor engineering are the scientific foundation for the analysis of most environmental engineering processes, both occurring in nature and invented by men. The need to quantify and compare processes led scientists and engineers throughout last century to develop what is now referred as Chemical Reaction Engineering (CRE).

Wastewater Effluent Discharge: Effects and Treatment …

divided into two broad categories: biological and chemical (Kris, 2007). 2.1. Ecological impacts The major chemical pollutants in wastewater areavy metals, detergents, e nitrogen, phosphorus, h pesticides and hydrocarbons. Of these chemicals, the two commonest nutrient limiting ones are nitrogen and phosphorus (Larsdotter, 2006).

Engineering Project Proposal

Appendix B. To better guide the design the relative importance of each customer requirement was determined through a pairwise comparison, as seen in Appendix D. The customer requirements were then translated to quantitative engineering specifications through benchmarking of existing PECVD designs and consultation with the project sponsors.
