http://chemcircle.blogspot.com/2009/12/e-quilibrium-means-condition-of-balance.html
Friday, December 18, 2009. E quilibrium means a condition of balance. In thermodynamics the concept includes not only a balance of forces, but also a balance of other influences. Each kind of influence refers to a particular aspect of thermodynamic (complete) equilibrium. Thermal equilibrium refers to an equality of temperature, mechanical equilibrium to an equality of pressure, and phase equilibrium to an equality of chemical potentials. August 12, 2016 at 2:49 AM.

Chemical Engineering: What do you know about POOL BOILING??
http://chemcircle.blogspot.com/2009/12/what-do-you-know-about-pool-boiling.html
Sunday, December 13, 2009. What do you know about POOL BOILING? 1) Pool boiling occurs when a heater is submerged in a pool of initially stagnant liquid. 2) When the surface temperature of the heater exceeds the saturation temperature of the liquid by a sufficient amount, vapor bubbles nucleate on the heater surface. 4) Nucleation is a molecular-scale process in which a small bubble (nucleus) of a size just in excess of the thermodynamic equilibrium is formed. At the bubble interface. We manufacture wide...
Chemical Engineering: February 2010
http://chemcircle.blogspot.com/2010_02_01_archive.html
Thursday, February 18, 2010. Selecting Entrainers for Azeotropic Distillation. An entrainer facilitates the separation of an azeotropic mixture by selectively altering the relative volatilities of the components in question, thereby effectively "breaking" the azeotrope. The entrainer is specific to the mixture in question - e.g., benzene is a feasible entrainer for separating ethanol and water, but not for separating ethanol and methyl ethyl ketone - so there are no universal entrainers. Various commerci...
Chemical Engineering: Size and Type of Heat Exchanger
http://chemcircle.blogspot.com/2009/12/size-and-type-of-heat-exchanger.html
Thursday, December 10, 2009. Size and Type of Heat Exchanger. Heat exchangers basics, the knowledge of heat exchanger and its importance in industry should be known. Do you have any idea, how to size heat exchanger and its type designated? First we will consider sizing part; what do you mean by sizing designations? How to designate shell diameter, shell thickness , heat exchanger length, tubes dimensions, baffle size etc. Theoretical explanation is as fallows:. U-tube exchanger (U) with bonnet-type stati...
Chemical Engineering: December 2009
http://chemcircle.blogspot.com/2009_12_01_archive.html
Saturday, December 19, 2009. Terms in Kinetic Models for Nonelementary Reactions. The types of intermediates we may postulate are suggested by the chemistry. Of the materials. These may be grouped as follows. Free atoms or larger fragments of stable molecules that contain one or more unpaired electrons are called free radicals.The unpaired electron is designated by a dot in the chemical symbol for the substance. Some free. Radicals are relatively stable, such as triphenylmethyl. Ions and Polar Substances.

Chemical Cleaning - Chemical Circulation - Air Blows - Hydrolaze
Chemical Cleaning - Chemical Circulation. Air Blowing - De Greasing - Hydro Testing - Equipment Rentals. Chemical cleaning or Chemical Circulation is a pre-commissioning procedure that generally refers to the cleaning of a boiler or HRSG with chemistry. Formulated to remove mill scale from the water tubes. It is also used on piping and vessels that need to have mill scale removed as well. This mill scale removal minimizes tube failures during startup. Cleaned metal is passivated with a passivating agent.
