B-Dry: Glycol Dehydration Units

B-Dry Overview

Glycol dehydration is the process of removing water vapor from natural gas to minimize hydrates, reduce pipeline corrosion, and ensure the integrity of downstream or downhole equipment. Bold’s Modular Glycol Dehydration Units are packaged with inlet filtration, absorber, regeneration system with redundant pumps, charcoal filter, BTEX system, and telemetry all encompassed on a single lift skid.

How it Works

Saturated gas enters the glycol dehydration unit through the gas inlet of the filter separator to remove particulates that could contaminate the glycol system. The saturated gas flows from the filter separator to the inlet scrubber of the glycol absorber tower where it ascends through the tower’s packing or bubble cap trays as glycol descends in a counter current flow to aid in the absorption process. Dry gas exits the top of the tower and passes through the glycol/gas heat exchanger to the gas outlet. The rich glycol is passed through a regeneration cycle, where it is conditioned back to a lean state for recirculation.

The Bold Advantage


  • Utilizes Emerson’s Zedi Cloud Platform to remotely monitor operations providing real time data, alarms, and reporting
  • Dehydration units are NACE Compliant and built to ASME Code
  • Modular design is built with all components allowing units to be set by a single lift. Our design reduces safety exposure, time, and installation and freight costs because only one truck is needed for transportation

Environmental Impact

  • Environmentally friendly, with the ability to combust any non-condensable BTEX vapors in the reboiler versus any VOCs venting straight to atmosphere
  • Our single skidded modular design reduces freight emissions only utilizing one truck
