Levels of analysis, Description and calculation of the CHARACTERISTIC TOURISM INDUSTRIES.

A complex chemical manufacturing process is a combination of elementary physical, physico-chemical and chemical processes. The number of elementary processes, their characteristics and define the structure of the sequence of the CHARACTERISTIC TOURISM INDUSTRIES in General. In the vast majority of practical cases of the CHARACTERISTIC TOURISM INDUSTRIES structure is complex and very difficult to correctly select technological mode of holding them. Indeed, each reaction is characterized by its type influences the basic parameters-temperature, pressure, concentration.

In addition, reactions accompanied by mass transfer, selection or absorption of heat and relevant heat exchange. Study of the CHARACTERISTIC TOURISM INDUSTRIES to choose rational technological and management regimes are not the complex set of elementary processes, and piece by piece (by levels). Level is a simple components flowing complex process. It is a tiered approach allows the most correct and quick selection of technological regimes of complex CHARACTERISTIC TOURISM INDUSTRIES and their management. Thus, analysis and description of the CHARACTERISTIC TOURISM INDUSTRIES hold consistently, taking into account the level of the.

Molecular level involves the description of processes like molecular interaction of reactive substances. Take, What substances react well mixed and their molecules can freely interact with each other. Flow CHARACTERISTIC TOURISM INDUSTRIES describes the regularities of the kinetics of chemical reactions. When describing, analysis and calculation of chemical reactions as an element of the CHARACTERISTIC TOURISM INDUSTRIES use known kinetic laws without opening the reaction mechanism. So they say, that course of conduct formal language process kinetics. In the simplest case, these laws can be used to describe a homogeneous processes, When reagents, effective reaction, good pre mixed, as well as for heterogeneous processes, the kinetic field in the periodic action.

On small volume level Describes the flow of heterogeneous processes for small volume interacting phases, for example, particles of solid material, reacting with a gas or liquid, grain catalyst, gas bubbles, rising in the liquid, drops of liquid, washed by gas, etc. The need to consider the processes at this level is related to the fact, that analysis and calculation of heterogeneous processes knowledge flow patterns only chemical reactions in most cases insufficient. These laws should be supplemented by the flow patterns of the physical processes of heat and mass transfer. The joint course of chemical reactions and processes of heat transfer and mass describes patterns macro.

Flow rate considering the flow of particulate on the totality of the process, liquid drops, catalyst grains and other varieties 2malogo volume», being in the flow of reactive substances. Takes into account the effects, related to the nature of traffic flows, changing temperatures and concentrations in various sections of the reactionary volume. For heterogeneous processes their leakage patterns in small volume are complemented by changes in the concentration and temperature patterns along the length of the reaction zone, through which passes a stream of.

Reactor level considers the design features of the reaction zones, their number, mutual location, the ratio of technological process with the passage of the stream from one reaction to another zone.

The level of chemical-technological system (XTC) takes into account the interlinkages between the reactors, heat exchangers, mixers and other devices, used for processing raw materials into finished products.
