Oxygen industrial uses

It is now important for us to explain the nature of systems of many compartments and chemicals. Why should systems evolve not only new chemistry but do it in many compartments rather than in a simple single compartment The question applies equally to the manner in which industrial plants or organisms develop. Any compartment is, of course, based upon a division of space, either by physical boundaries or by fields (Table 3.7 see also Tables 3.2 and 3.4). We saw that abiotic cycles of water (clouds) and oxygen (ozone layer) formed in compartments containing droplets or ozone, respectively. Here each system has one component, controlling fields, with no physical barriers or information transfer. 

This oxygen sensor system has been successfully used by us with a number of different types of packaged foods and packaging processes, being continuously developed and optimized in these real-life conditions and applications. It was validated in several small laboratory scale and medium industrial scale trials19,30 with the following foods and processes ...

Blending also plays a role in the chemical industry. The use of Raman spectroscopy to control gasoline blending, particularly oxygenated species such as methanol, ethanol, propanols, and butanols, is discussed in US patent 5,596,196.64 The system can be operated in a feed-forward and/or feedback control scheme. In feed-forward, the composition of each of six remote feed tanks is measured sequentially. A control computer then...
