Demianchuk Y. Improvement of technology for absorbtion dehumidifying of natural gas

The given thesis contains a possible solution of an important task of national economy – reduction of power and material costs of natural gas absorbtion dehumidifying. There has been suggested a new technological scheme for gas dehumidifying installation. Due to tubular-string technology this scheme allows to reduce considerably both the loss of high-cost absorbent along with drained gas flow thanks to a film diagram of the absorbent motion and the quantity of thermal energy at the stage of saturated absorbent reactivation. The latter is achieved by decreasing the process irreversibility in the parallel processes of heat and mass exchange in tubal and inter-tubal spaces within the height of the apparatus mass-exchange zone. To achieve the proper level of efficiency of the above-mentioned processes, there has been suggested a tubular nozzle, which has been tested on a created experimental bench.
