Wine and Wine Making

Aug 02 2010 12:57 PM | Chris Haslego in Other Topics

Wine is fermented grape juice. Wine can be made from grapes, fruits, berries etc. Most wine, though , is made from grapes. And no matter what the wine is made from, there must be fermentation, that is, that sugar be transformed into alcohol. If the amount of alcohol is relatively low, the result is wine. If it is high, the result is a "distilled liquor," something like gin or vodka.

Why Become a Chemical Engineer?

May 30 2012 06:50 PM | Chris Haslego in For Students

How about a career where the opportunities are endless? Trying not to sound like an advertisement, I'd like to describe some of the more common careers pursued with a Chemical Engineering degree. Firstly, if you're considering studying Chemical Engineering, but you're a little timid because of the horror stories that you hear, you actually may want to think about it some more!

What is a Heat Pipe?

Nov 08 2010 01:20 PM | Chris Haslego in Other Topics

A heat pipe is a simple device that can quickly transfer heat from one point to another. They are often referred to as the "superconductors" of heat as they possess an extra ordinary heat transfer capacity and rate with almost no heat loss. The idea of...

Water Chemistry and Treatment

Jun 03 2012 06:50 PM | Chris Haslego in Utilities

Water is a natural solvent. Rain water is acidic due to carbon dioxide picked up in the atmosphere. Water and CO2 make carbonic acid (acid rain). Water hardness is primarily calcium and magnesium. Calcium is limestone - common throughout Midwest. Acid water dissolves limestone, iron, and other minerals in soil.

Valve Sizing and Selection

Dec 05 2011 03:20 PM | Chris Haslego in Fluid Flow

Sizing flow valves is a science with many rules of thumb that few people agree on. In this article I'll try to define a more standard procedure for sizing a valve as well as helping to select the appropriate type of valve. **Please note that the corr...

Understanding Compressible Flow

Nov 08 2010 01:40 PM | rxnarang in Fluid Flow

Understanding the flow of compressible fluids in pipes is necessary for a robust design of process plants. The main difference between incompressible fluid, like water, and compressible fluid, vapor, is the greater change in pressure and density. This...

Steam Tracing with MS Excel

May 24 2012 06:50 PM | adelange in Heat Transfer

Heat tracing is used to prevent heat loss from process fluids being transported in process fluid pipes, when there is risk of damage to piping, or interference with operation such as fouling or blockage, caused by the congealing, increase in viscosity, or separation of components, in the fluid below certain temperatures, or when there is risk of formation of corrosive substances or water due to condensation in corrosive services.

Statistical Process Control: Process and Qualit...

Jul 14 2012 06:50 PM | Chris Haslego in Process and Reactions

Statistical Process Control (SPC) provides a way to monitor chemical and other processes. We'll focus on continuous chemical processes and how the process and quality control departments utilize SPC. Process control engineers use SPC to monitor a process's stability, consistency and overall performance. Quality control engineers use SPC to see if the process is functioning within quality standards. In industry, these two departments work together to monitor a chemical process.
