Increasing the efficiency of the Kalmas underground gas storage during gas injection and exhaust

Technologies for increasing efficiency of gas preparation during its abstraction from Kalmass Underground Gas Storage (UGS) have been reviewed. Irregularity of gas consumption is one of the main parameters of the underground gas storages operation mode. UGSes are an integral part of gas transportation network and provide for its normal operation. Increase of gas abstraction process efficiency in the Republic is related to improvement of existing technologies for gas treatment before transportation. For the purpose of increasing active volume of injected gas, the current state of technology for gas treatment before transportation, thermodynamic parameters of all wells and production equipment at Kalmass UGS have been analyzed. A series of research studies for development of new technology for increasing the quality of treated gas under conditions of Kalmass UGS have been carried out. On the basis of research studies new complex absorbent for gas dehydration and hydrate formation prevention has been developed on the basis of local petrochemical products. In addition, optimal thermodynamic and technological mode of unit operation during the period of gas abstraction from Kalmass UGS has been selected.
