Free Environmental Ebooks Hazardous Waste Generator Regulations - September 8, 2008

This web-based document serves as a user-friendly reference to assist Environmental Protection Agency (EPA) and state staff, industrial facilities generating and managing hazardous wastes as well as the general public, in locating and understanding the current RCRA hazardous waste generator regulatory requirements.1 These requirements are located primarily in Title 40 of the Code of Federal Regulations (CFR) at Part 262. The requirements as laid out in this reference document are organized by...

Free Ebooks Ammonia and Urea Production - September 6, 2008

Ammonia and urea are two chemicals which are very important. This article covers a process used by Petrochem in Kapuni, South Taranaki, to synthesise ammonia from natural gas and air, then synthesise urea from this ammonia and carbon dioxide. As has been stated above, most of the ammonia is used on site in the production of urea. The remainder is sold domestically for use in industrial refrigeration systems and other applications that require anhydrous ammonia. The urea is used as a...

Virtual Sensors: A revolution in Control Engineering - September 4, 2008

Any process that must be monitored requires sensors to find the variables of a process in real time. If required to monitor a large number of variables in the process, in the same proportion will require a large number of sensors for these variables. The sensors are costly, require maintenance, and can be calibrated become very sensitive, besides needing a hardware that connects with the monitoring unit. Would not it be better if we could dispense with a few sensors and still be able to monitor.

New generation of microprocessors: parallel processing - September 4, 2008

The numerical calculation is a key tool for chemical engineering, as well as in many other sciences. An example of this are the simulation software and process optimization. When the number of variables and equations to solve is high, the limiting factor is the processing capacity. Advances in the speed of microprocessors are reaching their practical limit, and how to obtain higher performance then is to use multiple CPUs in parallel (multi-core). Another activity that requires more and more...
