AMOCO Empress Plant

Turboexpander compressor Dew point control duty AMOCO Empress Plant, Canada 99.80... 

The BP-Amoco Empress plant complex consists of three interconnected facilities located on a one mile square site. It operates 24 hours a day, 365 days a year, employing 70 personnel who work two shifts. If the plant were to shut down for a period of time, suppliers would have to sell their product on the spot market and forego profits. Also, from the customer s perspective, even a plant with reserves would soon run out of products. 

The extraction process at BP-Amoco Empress begins with natural gas arriving at the plant at about 15°C and 600 psi pressure. The gas is dehydrated to a -90°C dewpoint by means of molecular sieves. Still at 600 psi, the gas is introduced into heat exchangers and cooled to -70°C, at which point it begins to liquify in a separator.
