WebThe dehydration process is simple—wet gas contacts dry glycol, and the glycol absorbs water from the gas. Wet gas enters the tower at the bottom. Dry glycol flows down the tower from the top, from tray to tray or through packing material. Schlumberger glycol dehydration processes remove water vapor from natural gas, which Websolvents or gases are used. A schematic drawing of a countercurrent packed tower is shown in Figure 1.1. In this figure, the packing is separated into two sections. This configuration is more expensive than designs where the packing is not so divided.[5] Figure 1.1: Packed Tower for Gas Absorption
