Silence can say more than a thousand words.
This day shall unite us all about this unbelievable painful & shockingevent and show some respect and love to those who lost their loved ones. On April 30th 2007, the Blogosphere will hold a One-Day Blog Silence inhonor of the victims at Virginia Tech. More then 30 died at the US college massacre.

This technique is especially useful for equilibrium-limited reactions such as esterification and ester hydrolysis reactions. Conversion can be increased far beyond what is expected by the equilibrium due to the continuous removal of reaction products from the reactive zone. This helps reduce capital and investment costs and may be important for sustainable development due to a lower consumption of resources.

Plant Innovation Award Winner...
The Plant Innovation Award (PIA) was inaugurated in 2005 by Chemical Processing to enhance the peer recognition of engineers who solve challenging problems at existing facilities with ingenuity and creativity. Unfortunately, such engineers rarely get visibility beyond their employers for such accomplishments. PIA is the only public award of its kind.
World Intellectual Property Day
Most people are aware of intellectual property (IP) - of copyright, patents, industrial designs and trademarks. But many still view these as business or legal concepts with little relevance to their own lives. To address this gap, WORLD INTELLECTUAL PROPERTY ORGANISATION (WIPO) ’s Member decided in 2000 to designate an annual World Intellectual Property Day. They chose April 26, the date on which the Convention establishing WIPO originally entered into force in 1970.
a message from WIPO Director General Kamir Idris.
“World Intellectual Property Day is an opportunity to encourage people to think about the role played by intellectual property in everyday life, and about its importance in stimulating and safeguarding innovation and creativity”. ..

A packed bed is a hollow tube or pipe that is filled with a packing material. The packing can be randomly filled small objects like Raschig rings or else it can be a specifically designed structured packing.
The purpose of a packed bed is typically to improve contact between two phases in a chemical or similar process. Packed beds can be used in a chemical reactor, distillation process, or a scrubber, but packed beds have also been used to store heat in chemical plants. In this case, hot gases are allowed to escape through a vessel that is packed with a refractory material until the packing is hot. Air or other cool gas is then fed back to the plant through the hot bed, thereby pre-heating the gas feed.
- PROCESS WITH 2-PROCESS FLUIDS (liquid- gas, liquid-liquid, liquid-solid, liquid-vapor) are in contact and separation take place.
- LOW PRESSURE DROP (typically 0.35 - 2mm Hg per theoretical plate for packed column compared to 3.05m Hg for trays)
- HIGH CAPACITY
- LOW LIQUID HOLD-UP
- GOOD RESISTANCE TO FOULING

Distillation is a method of separating chemical substances based on differences in their volatilities. Distillation usually forms part of a larger chemical process, and is thus referred to as a unit operation.
Distillation has a number of uses. It is used to separate crude oil into more fractions for specific uses such as transport, power generation and heating. Water is distilled to remove impurities, such as salt from sea water. Air is distilled to its components such as oxygen for medical applications and helium for party balloons. The use of distillation on fermented solutions to produce distilled beverages with a higher alcohol content is perhaps the oldest form of distillation, known since ancient times.
An introduction on distillation site for fresh engineer and refresher for experienced engineer being maintained by M.T. Tham from Department of Chemical and Process Engineering at the University of Newcastle, Tyne, UK.
The purpose of below notes is to expose you to the terminology used in distillation practice and to give a very basic introduction to:
- column internals
- distillation principles
- vapour liquid equilibria
- distillation column design
- the factors that affect distillation column operation
Will bring to you some industrial distillation related stuff next round...

Following tabulate listing of useful documents and links for STEAM & WATER engineering... if some of you have better site, please drop me a comments...
Armstrong has been sharing know-how since they invented the energy-efficient inverted bucket steam trap in 1911. In the years since, customers’ savings have proven again and again that knowledge not shared is energy wasted. Armstrong’s developments and improvements in steam trap design and function have led to countless savings in energy, time and money. This section has grown out of our decades of sharing and expanding what we’ve learned.It deals with the operating principles of steam traps and outlines their specific applications to a wide variety of products and industries. This section also includes Recommendation Charts that summarize our findings on which type of trap will give optimum performance in a given situation and why.
The most basic part of energy management is utilizing all valuable Btu within the steam system. Depending on the pressure, condensate exiting a trap contains approximately 20% of the heat energy transferred at the boiler in the form of sensible heat. Effective recovery of condensate reduces three tangible costs of producing steam :
- Fuel/energy costs associated with producing steam
- Boiler water make-up and sewage treatment
- Boiler water chemical treatment

Thermo Utilities v3.0(1.75 Mb) offers a large number of functions for calculating the properties of water, steam, air, flue gases and other fluids. The functions used for steam and water properties are based on a set of equations accepted by the members of the Sixth International Conference on the Properties of Steam. The sets of equations are also known as "IFC Formulation for Industrial Use". Thermo Utilities calculates the properties of dry air, moist air, exhaust and flue gases by using equations accepted by ASHRAE and CIBSE (Chartered Institute of Building Services Engineers). Lee-Kesler method used in this package can be applied to a large number of chemicals for estimating thermodynamic properties. The database accompanied with this package for use with Lee-Kesler method supports more than 450 chemicals. The package also offers a large number of inverse functions which are useful for applied thermodynamics calculations. (source : Taftan Data)
