Dew Point Control System Operation & Maintenance


May 12 – 14, 2014  | Keterangan Harga di Proposal at Bandung


Dew point is defined as the temperature at which vapor begins to condense. By managing hydrocarbon dew point, hydrocarbon condensation can be prevented in cold spots under rivers and lakes where the liquids collect in the low areas and then often move as a slug through the system, over pressuring the pipe, and overpowering liquid handling facilities, flowing into compressors and end user sales points. Proper managing of gas dew point can also prevent liquids from forming as the gas cools while flowing through pressure reduction stations that feed end user supply systems. Controlling dew point is also necessary to qualify the pipeline to market gas to high efficiency gas turbine end users that require a dry and consistent quality fuel.
