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 feed gas conditions. This month’s Tip of the Month compares the required size of major equipment for the two-tower system with the three-tower system, considering a number of key parameters.

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), respectively. Removal of water content to this very low level is essential to prevent freezing. This month’s article discusses feed gas flow rate, pressure, and temperature effect(s).

Gas-Liquid Separators Sizing Parameter

In this Tip of the Month (TOTM), we will focus on the application of Souders-Brown approach in gas-liquid separators and present diagram, simple correlations and tables to estimate the Souders-Brown equation constant, KS (the so called sizing parameter). We will consider both vertical and horizontal gas-liquid separators. Knowing the actual gas flow rate through the vessel, one can use KS parameter to determine the maximum allowable gas velocity through the vessel and determine the required separator diameter. One can also use the appropriate value of KS to size the mist extractor in the vessel. The performance of a gas-liquid separator is highly dependent on the value of KS; therefore, the choice of appropriate KS –values is important.

PetroSkills Instructors welcomed into SPE’s ‘Legion of Honor’

Two PetroSkills instructors, Mr. Richard Schroeder and Dr. George Slater, were recently welcomed into the Society of Petroleum Engineers (SPE) Legion of Honor. Both have held their SPE membership for 50 consecutive years. SPE honored each with a commemorative plaque and exempt dues for the remainder of their membership.
