Equipment design efficiency

Typical new equipment design efficiencies are between 99 and 99.9%. Older existing equipment have a range of actual operating efficiencies of 95 to 99.9%. Several factors determine fabric filter collection efficiency. These include gas filtration velocity, particle characteristics, fabric characteristics, and cleaning mechanism. In general, collection efficiency increases with increasing filtration velocity and particle size. 

Older existing cartridge collector types have a range of actual operating efficiencies of 99 to 99.9% for PM,q and PMj j. Typical new equipment design efficiencies are between 99.99 and 99.999 -t- %. In addition, commercially available designs are able to control submicron PM (0.8 m in diameter or greater) with a removal efficiency of 99.999 + %. 

Typical new equipment design efficiencies are between 99 and 99.9%. Older existing equipment have a range of actual operating efficiencies of 90 to 99.9%. 

The residual oxygen content remaining after deaeration varies depending on equipment design and operational efficiency, but suffice to say that, unless the deaerator is scrupulously well maintained, its per-... 

The considerations above have been utilized by various manufacturers in designing efficient ultrafiltration and reverse osmosis equipment. 

Plant description. Two nearly identical 430-Mw(e), western, conventional pulverized-coal-utility boilers (referred to as plants A and D) were tested. Both units use tangentially fired burners and burn low-sulfur 200-mesh coal of heat content approximately 27 000 J/g. Both units are equipped with cold-side electrostatic precipitators (ESP) of design efficiency of 99.5% or greater, and a modern flue-gas desulfurization (FGD) system consisting of four verticle spray towers. 

At this writing, we have designed and built a small production unit to test and demonstrate the CBI process in a continuous system. The equipment design (patent pending) incorporates mechanical simplicity and energy efficiency into a reliable,... 

Since the chemical industry operates by handling potentially hazardous materials safely, safety has always been an important consideration for chemical engineers. Engineers have never been able to discharge their professional responsibility only by designing efficient equipment or developing efficient processes. Today society has expanded that traditional responsibility to include environmental and community protection. The chemical industry s operations and products should not have an unacceptable impact upon its neighbors, its customers, or the environment. 

Dry process cement production facilities often have several other types of manufacturing equipment designed to increase fuel efficiency. First, many dry process kilns add a preheater to the feed end of the kiln to begin heating of the feed prior to its entrance to the kiln. Two main types of preheaters exist, the suspension preheater and the traveling grate preheater both use hot, exiting kiln air to facilitate a more efficient heat transfer to the feed than could occur in the feed end of the kiln itself.1 This... 

Lastly, manufacturability of a dmg product can be affected by the physical properties of the drug substance. Manufacturability refers to the ability to execute a process efficiently, without excessive operator intervention, and without the need for specialized equipment designed solely to overcome specific product properties. In the case of drug product manufacturing, this typically includes the ability to transfer powder blends through each drug product unit operation. The physical properties of the API such as particle size and shape can affect the flowability of the intermediate and final powder blends.
