RESEARCH ON THE EFFECT OF THE BALANCE, DRIVING FORCE AND KINETICS OF THE ABSORPTION PROCESS ON FOAMING IN THE PROCESS OF PURIFICATION OF GASES FROM SOUR COMPONENTS USING MDEA

ABSTRACT

Natural gas is one of the most widely used and consumed natural resources among energy resources today. In this case, its low cost and simplicity under favorable conditions of production, transportation and storage, as well as processing technologies, are the main industrial factor, while gas extraction and processing, on the other hand, have great economic efficiency. This article provides information about the world's natural gas reserves, their physico-chemical properties and prospects for the extraction, processing and use of natural gas.

АННОТАЦИЯ

Природный газ на сегодняшний день является одним из наиболее широко используемых и потребляемых природных ресурсов среди энергоресурсов. При этом его низкая стоимость и простота при благоприятных условиях добычи, транспортировки и хранения, а также технологиях переработки являются основным промышленным фактором, в то время как добыча и переработка газа, с другой стороны, обладают большой экономической эффективностью. В этой статье представлена информация о мировых запасах природного газа, их физико-химических свойствах и перспективах добычи, переработки и использования природного газа.

The fact that the absorption process is typical of substance exchange processes between interacting phases is sabali, the basis of substance exchange laws in revealing these processes.

In matter exchange processes, two phases are usually involved (in some cases there may also be many), and in the interphase boundary, matter exchange processes go as one phase moves to the other one phase. The course of substance exchange processes can be divided into three [1-2]:

1. Mixing nuclear-giving phase components in the separation chega;

2. The transition of components at the boundary of phase separation;

3. The phases are the mixing of the component at the separation limit to the receiver.

The transfer of substances from one phase to another at the boundary of the phase separation is called the transfer of matter, on the surfaces of the separation, the transfer of substances from the volume of phases to the opposite direction is called-the processes of transport of substances.

The interaction of two phases according to the second law of thermodynamics, their state goes in the direction of equilibrium formation, and the temperature and pressure of the phases in equilibrium and thus the resulting phases are characterized by the chemical potential of each of the comopnents. The driving force of the transition of the desired component from one phase to another is caused by the difference in the chemical potential of the comopnent in the interacting phases. The transfer of a component goes in the direction of its decrease in chemical potential [3].

In many cases, matter is involved in exchange processes in three fields: first-phase distributives (G), second-phase distributives (L), and distributives (M) that go from one phase to the other.

The transfer of matter from one phase to another (where the rain components pass from one phase to the other), whose components do not undergo a reciprocal chemical reaction, is called equilibrium phase equilibrium (or phaseout), which occurs in heterogeneous systems. One of the most important general laws of physical chemistry was established in 1876 by V. Phase equilibrium introduced into science by Gibbs; is a law on the phase rule, and is referred to by the name of the phase rule [4-5]. Before inducing a phase rule, it is necessary to give a definition to the concepts of the degree of freedom of the system" phase"," component"," number of components". From other parts of the system, the boundary is separated by surfaces, from which, differing in its thermodynamic properties and chemical composition, the components that can stand independently of each other time and consist of the same – sex substances-are called components of the system. The smallest number of variations of a substance necessary to represent the chemical composition of any phase in the system is called the number of components of the system. The properties of the system will depend on the number of components. If chemical reactions do not occur in the system; the number of components is equal to the number of structural clamps; the number of components in the opposite hole (when there are chemical reactions) is less than the number of components. If chemical reactions go between the component parts at equilibrium, the number of components must be subtracted from the number of components to the number of chemical reactions that bind the concentrates of these substances. To better understand the terms presented here, let's calculate the number of components in single-phase and multi-phase systems. The simplest example for a multi-component single-phase system is a mixture of gases composed of helium, hydrogen, and argon gases. In this system, any chemical reaction cannot go. For this, the total content is equal to the number of parts.

The hypothesis is that an equilibrium system consisting of a kilaylik, N-phase, and K-component is berylgai, in which every component in the system can freely move from one phase to another. Let's determine the degree of masculinity in this system. The state of a given system is clearly expressed in the knowledge of pressure, temperature and the percentage of each component in any phase. In such a system, the number of degrees of freedom is equal to the value that subtracts the number of equations connecting these parameters with each other from the total number of parameters. Here, one should pay attention to the fact that the composition of any phase in the system is expressed in the phakat (K-1) component concentration bilai, since the sum of all components is equal to 100%. If we know which phase (K-1) component concentrates, we can also know the concentration of the K – component. The parameters of the system must have values such that the chemical potential of any component in all phases is equal to the same value [6-7].

A characteristic sign of a system in an equilibrium state consisting of several phases is two: one – the chemical potential of substances in all phases is equal to one (has the same wear), the other-the temperatures of the phases will also be the same. Even when a system of several phases comes into equilibrium, the processes of transition of molecules from one phase to another do not stop. For example, in an equilibrium system consisting of "water – water vapor", molecules always pass from water to steam and vice versa from Steam to water. At equilibrium, the rate of evaporation of water is equal to the rate of condensation of steam.
