DEVELOPMENT OF A COLUMN WITH AN OPTIMAL CONSTRUCTION TO INCREASE THE EFFICIENCY OF CLEANING NATURAL GAS FROM SOUR COMPONENTS BY ABSORPTION METHOD OF MUBARAK GAS PROCESSING PLANT LLC

Abstract

Mubarak gas processing plant is one of the largest gas processing plants in Central Asia. The raw materials at the plant are high- and low-sulfur gases, which are cleaned of sour components by the absorption method. This process is carried out in a plate absorption column, using methyldiethanolamine as an absorbent. Sieve and trapezoidal plates are used in the column. At present, gas processing plants mainly use tubular absorption columns for cleaning gases from acidic components. This article presents the results of an experiment on the purification of high-sulfur gases at the Mubarak gas processing plant using a 40% solution of ethyldianolamine in a laboratory column with different types of tubular absorption. By comparing the results obtained from these experiments, it was possible to determine the optimal nozzle type for the process and the optimal hydrodynamic parameters of the process.
