Tubular heat exchanger GHE-BEU

gas/gashigh-pressure

In the gas pressure reduction process by the “Joule-Thomson” effect, temperature drops considerably (about 0.5°C per reduction bar are estimated). This fall in gas temperature can damage equipment due to formation of dangerous ice crystals produced by water vapor in the gas. In first stage stations in particular, gas must be heated before pressure is reduced, since high-pressure changes are usually involved. We recommend that, after reduction, gas temperature should not be below 5°C or at specific temperature according to custody transfer contracts. One of the best-established methods of heating gas in reduction stations is to use heat exchangers employing hot water or steam as their thermal carrier fluid. Gascat´s Heat Exchanger GHE-BEU are sized and designed to meet a very wide range of system requirements and process variations as pressure, temperature and Flow on a first reduction stage at Distribution pipelines.
