Preparation and the use of demineralized water for reciprocating engine-driven power plants in Azerbaijan

Preparation and the use of demineralized water for reciprocating engine-driven power plants in Azerbaijan is discussed. In Azerbaijan six reciprocating gas engine-driven power plants are in successful operation, in their cooling systems, water is demineralized by the membrane technology at the Sangachaly power plant. This water transported by tanker trucks is also used at the remaining five power plants. At the Sangachaly power plant water is treated with the use of the technology of ion exchange upstream of the membrane unit, while at the Shimal TPS, downstream of it. Control over the process of water treatment is carried out in the chemical laboratory from the analyses of water once every 24 h, with the use of four indicators and electrical conduction. Cleaning of membranes as needed is carried out by means of solutions with the use of reagents allowed for water treatment.
