What is the impact of Nitrogen on the Natural Gas Hydrate Formation Conditions?
Previously, we've discussed the hydrate phase behavior of sour natural gas mixtures. Specifically, we looked at carbon dioxide inhibits the hydrate formation slightly while hydrogen sulfide enhances hydrate formation considerably. This Tip of the Month (TOTM) will extend the previous study on the natural gas hydrate formation phase behavior. Specif...

Adsorption Dehydration: Two-Tower vs. Three-Tower System
There are different process configurations for adsorption dehydration systems. The most common arrangements are two-tower and three-tower configurations.
In past articles, we have discussed the efficient operation of molecular sieve dehydration units. Specifically, the benefits of standby time in the adsorption dehydration processes and impact of ...

What is the Impact of Feed Gas Conditions on the Adsorption Dehydration System?
Adsorption dehydration units can reduce the water content of a gas stream to less than 0.1 ppmv. The gas industry normally uses adsorption dehydration units upstream of a liquefied natural gas (LNG) plant or a deep natural gas liquid (NGL) extraction plant where the gas temperature reduces to less than -160 °C (-256 °F) and -100 °C (-148 °F), respe...
