Amine solutions can be used to remove hydrogen sulfide and/or carbon dioxide from hydrocarbon liquid streams. The reactions involved are essentially the same as those for removing the same constituents from natural gas. The primary difference in this process and the amine-gas sweetening process is the handling of two liquid phases in intimate contact [1].Continue Reading

The process gas pressure has a significant effect on the choice of hydrocarbon dewpoint (HCDP) control process. If the process inlet pressure is less than about 8000 kPa (1160 psia) and the sales gas pressure is 6900 kPa (1000 psia) or higher, the most common process choice is mechanical refrigeration. There are exceptions to this,Continue Reading

In 2017, approximately 31% of all the gas consumed worldwide was transported internationally. About 65% of this gas was transported via pipeline (21% of the total) and approximately 35% was transported as liquified natural gas (LNG) (10% of the total) [1]. Most of the gas transported internationally by pipeline was from Russia and Norway toContinue Reading

The main issue for cryogenic processing and transporting of a gas stream containing carbon dioxide is its frost formation. Solid carbon dioxide (dry ice) may form at low pressures when the temperature of a gas stream containing CO2 drops below the triple point temperature of CO2. The triple point temperature and pressure of CO2 are -56.57 °CContinue Reading
