There are many different ways to produce acetylene. Among them, such as manufacturing out of calcium carbide, pyrolysis of hydrocarbons and gas separation from gases which consist acetylene. All of these technologies are based on chemical or mass transfer processes, etc. However, they are energy consuming and pour on the environment. Production using pyrolysis spends a lot of heat in the process of selection of the product, so there is an opportunity to significantly improve the technical and economic performance using plasma process, but these measures have not been ever brought in real life. If we consider the process of production of reactive acetylene gas using dimethylformamide, it is certain that a large amount of dimethylformamide can spend to achieve the level of concentration in the reaction of acetylene gas. Only the following reasons, the quality of the incoming gas mixture can vary significantly. In this regard, we seek such factors by which the process will be more meet feasibility requirements and reduce the impact on the environment.
The manufacture of acetylene gas from the reaction gases is designed to produce high quality acetylene by mass transfer processes taking place in absorbers.
The process of mass transfer in the absorber is one of the most important steps in being saturated with acetylene production cycle. Production of acetylene from the reaction gas is the most economical way of obtaining acetylene because all unused products in the process of returning to a pure storage, where they can be used again in the process. The research on real objects is expensive, very difficult and dangerous, so this improvement is relevant and necessary.
To solve the problems of design of process equipment, synthesis and study of control systems the challenge of obtaining the mathematical model of the process object that best reproduce the properties of real prototype to a wide range of operation. For this purpose, a mathematical model is needed, which would most closely corresponds to the actual and also based on the complexity of the device and the usage of simplifications, which could be neglected .
Today we know a few models of packed absorbers, including regression models and mathematical models are based on the theory of fuzzy logic and fuzzy set theory. However, most of them do not allow simulating the dynamics of the process, and thus make it impossible to optimize dynamic processes.
