Introduction Rongteng glycol dehydration processes remove water vapor from natural gas, a natural gas treatment equipment, which helps prevent hydrate formation and corrosion and maximizes pipeline efficiency. Rongteng engineers fabricate and install complete dehydration systems, including custom and standard dehydration systems, glycol purification modules, glycol injection units, and stripping gas recovery systems. A complete program of support services is also available to satisfy every aspect of your dehydration problems. Working process The glycol 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.      Application Removal of water; benzene, toluene, ethylbenzene, and xylene (BTEX); and other volatile organic compounds (VOCs) from natural gas streams Natural gas dehydration   Benefit Enhances operational versatility Lower operating costs compared with conventional desiccants Lower capex compared with solid bed systems Reduced manufacturing and commissioning times through standardized unit offering (customized units also available) Streamlined packaging of hybrid systems   Bubble cap The special bubble cap configuration maximizes gas/glycol contact, removing water to levels below 5 lbm/MMcf. Systems can be designed to achieve levels down to less than 1 lbm/MMcf. The dehydrated gas leaves the tower at the top and returns to the pipeline or goes toother processing units.   The water-rich glycol eaves the tower at the bottom and goes to the reconcentration system. In the reconcentration system, the wet glycol is filtered of impurities and heated to 400 degF [204 degC].  Water escapes as steam, and the purified glycol returns to the tower where it contacts wet gas again.   The entire system operates reliably unattended. Controllers monitor pressures, temperatures, and other aspects of the system to ensure efficient operation.
