Natural Gas Dehydration and Sweetening
As raw nature gas normally contains saturated water, hydrogen sulfide, carbon dioxide and other impurities. These impurities should be removed as much as possible in order to meet the requirement of marketable gas.
Natual Gas Dehydration
If the temperature of pipeline walls or storage tanks decreases below the dew point of the water vapors present in the gas, the water starts to condense on those cold surfaces, and the following problems can appear:
1. Natural gas in combination with liquid water can form methane hydrate that may plug the valves, the fittings or even pipelines;
2. Natural gas dissolved in condensed water is corrosive, especially when it contains CO2 or H2S;
3. Condensed water in the pipeline causes slug flow and erosion;
4. Water vapor increases the volume and decreases the heating value of the gas;
5. Natural gas with the presence of water vapor cannot be operated on cryogenic plants;
ENERGYCO has specially designed molecular sieve 3A and molecular sieve 4A with high water adsorption and CO2 capacity, excellent hydrothermal stability and good dynamic characteristic for natural gas dehydration.
Natural Gas Sweetening
H2S and CO2 are commonly found in natural gas, but unfortunately they get highly corrosive in the presence of H2O. Natural Gas sweetening also known as Acid Gas Removal refers to a group of processes that remove Carbon Dioxide (CO2) and Hydrogen Sulfide (H2S) from natural gas.
ENERGYCO has specially designed molecular sieve 5A with high mechanical and chemical resistance, best adsorption capacity for removal of H2S, CO2.
ENERGYCO has specially designed molecular sieve 13X with high performance COS removal capacity and best crush strength.
