TECHNOLOGICAL AND CONSTRUCTIVE OPTIMIZATION OF SEPARATORS OF THE GAS PREPARATION INSTALLATION

Abstract

As a result of the analysis, it was determined that the urgent task is the development of methods for regime-technological and hardware-constructive optimization of the separation equipment of gas preparation plants. At the same time, attention should be paid not only to empirical dependencies, but also to numerical simulations. Preparation and processing of oil and gas are technological processes that are implemented with the help of technological lines, which in turn consist of a significant amount of basic equipment. At the same time, the existing installations are not always highly efficient and require improvement, since over time the amount of target components in the raw materials extracted from the well decreases, and the content of water, paraffins and other harmful impurities increases. This forces to increase the intensity of separation and mass exchange processes. The proposed technique for optimizing technological and structural calculations of separation equipment (separators of the first and second stages) of the gas preparation plant, which allows determining the rational structural dimensions and optimal operational parameters to ensure a high degree of separation of the components of the gas mixture. For the numerical study and optimization of chemical-technological processes of gas preparation plants intended for the production of hydrocarbon products, the methods of static and dynamic optimization simulations of chemical-technological processes were chosen using tools of CAE-systems of thermodynamic modeling, which made it possible to quickly and accurately use known mathematical models calculate heat and material balances of both individual technological equipment and installations as a whole. This made it possible to obtain the maximum efficiency of the equipment and the efficiency of the installations as a whole. The simulated operation of the atmospheric hydrocarbon processing plant and the hydrocarbon gas preparation plant for which the optimal operating modes of the separators of the first and second stages of the hydrocarbon gas preparation plant are determined.
