Process Development from

After tlie system has been defined, a hazard evaluation technique can be used to identify different types of hazards within tlie system components and to propose possible solutions to eliminate the hazards. This topic is treated in more detail in the next t o chapters. These procedures are e.xtremely useful in identifying system modes and failures that can contribute to the occurrence of accidents diey should be an integral part of different phases of process development from conceptual design to installation, operation, and maintenance. The hazard evaluation tecliniques tliat are useful in tlie preliminary and detailed stages of tlie design process include ... 

New processes, developed from laboratory research, through pilot plant, to a commercial process. Even here, most of the unit operations and process equipment will use established designs. 

Tower Biology A biological waste-treatment process, developed from the Activated Sludge process. The sludge is contained in a tall tower, at the base of which oxygen is injected as small bubbles. The bubbles are almost completely absorbed by the time they reach the surface of the liquid. The system uses less energy than does surface aeration. Developed by Bayer in 1980 for its plant at Leverkusen, Germany subsequently adopted in India and then elsewhere.

A recent process development from Zurich by M. Bariska (20) has a number of important and interesting features. The method is specifically designed to test the applicability of ammonia forming to commercial practice. Secondly it constitutes a lower extremum, an investigation of conditions of minimum useful plasticity. Furthermore it is based on extensive investigations of kinetics, thermodynamics, sorption processes, and structural changes characteristics of the ammonia wood system.

There have been several investigations of nitrogen fixation reactions in RF plasma devices, however, and some patents have been granted protecting processes developed from these investigations.
