Chemical engineering

Chemical thermodynamics is the investigation of the exchange of heat and work with chemical reactions or with physical changes of state inside the bounds of the laws of thermodynamics. It involves not only laboratory measurements of different thermodynamic properties, but also the utilization of mathematical strategies to the investigation of chemical questions and the spontaneity of processes. The structure of chemical thermodynamics depends on the initial two laws of thermodynamics. Beginning

Challenges in teaching thermodynamics for biotechnology engineering students Praphulla Rao1,*, Prathibha N2 1,2 B M S College of Engineering, Bangalore, Karnataka * Corresponding author. Tel: +91 9036471963, E-mail: praphulla.rao@gmail.com Abstract—The disciplines of physics, biology, and chemistry have adopted highly diverse approaches and strategies on thermodynamics education. Many studies have addressed the problems in making the students understand the fundamentals in thermodynamics

Over the past few decades, there has been a rapid increase in the use of the stirred tank bioreactors. The volumetric mass transfer coefficient (kLa) is often used to compare the efficiency of the bioreactors and as an important scale-up factor. It characterizes the oxygen mass transfer in stirred tank bioreactors. In the present work, a mathematical and statistical approach was adopted to study the effects of the various experimental variables on volumetric mass transfer coefficient in a 1 L stirred

Olefins are usually produced in large quantities in the petrochemical industry. The separation of olefins from paraffins is of primary importance to the chemical industry. Olefin/paraffin mixture is difficult to separate due to their similar physical and chemical properties such as molecular sizes and boiling point. The most common method for olefin/paraffin separation in the industry is the distillation process, commonly known as cryogenic distillation which is considered as one of the most energy-intensive

General Instrumentation in a Power Plant In a Thermal Power Plant, Chemical Energy of fuel is converted to Electrical Energy. Actually this energy conversion takes place in different stages. Firstly, in Boiler, the chemical energy in fuel is converted into heat energy. During process of combustion the carbon, sulphur etc available in the fuel reacts with air and liberates heat and flue gases. This heat is absorbed by the water-walls of the furnace and steam is generated. Secondly, in Turbine this

Introduction Carboxylic acids (Lactic, propionic, caproic, acetic, picolinic etc.) are chemicals extensively used in pharmaceutical, food and other allied industries, as they find diverse application as reactants, solvents and even as catalysts in a few work instances (Talnikar et al., 2014). These acids when obtained by fermentation of sugars

Blacktown Water Treatment Plant Project Brief Version: 1.1 Date: 8/22/2014 Copy: Uncontrolled Document Acceptance and Release Notice This is Version 1.1 of the Blacktown Water Treatment Plant Project Brief. Title: Blacktown Water Treatment Plant. Background: This treatment plant is designed to remove potentially harmful substances from waste water. It also includes safe effluent discharge and production of agro-ash.

Answer each question in a short, typed paragraph or two. Your responses must be neatly typed, and free of major grammatical and spelling errors. Be specific – points will be deducted for vague or incoherent answers, as well as spelling and grammar problems. It’s always a good idea to make it easy for instructors/supervisors to give you credit for your work! 1) Case Study: Amy West suffered severe lacerations (cuts) on her legs from flying glass, when a bottle of carbonated soda exploded in a

operation derived from literature will be solved to demonstrate the features of the two methods and differentiate between them showing advantages and disadvantages of both. Introduction: Huge amount of energy and fresh resources (i.e. water, chemicals, solvents) are consumed by process industries to achieve the desired product specifications.There is a strong current drive to an efficient use of these resources amongst the few reasons for this drive include environmental sustainability, stringent

conversion, but pre-combustion treatments—such as gasification and oxy-combustion—also require the separation of H2 and O2¬ gases, respectively.1 Regardless of when the CCS stage occurs, CO2 capture is the most costly step with common approaches including chemical absorption, surface adsorption, and membrane technology. The most developed and commonly used technique is absorption, often using amines such as monoethanolamine (MEA).1 MEA is effective due to
