Gas Dehydration Skid (TEG / Molecular Sieve)

• Triethylene glycol (TEG) contactor with regeneration – continuous absorption in a contactor, with the glycol regenerated in a reboiler and still column.
• Twin-tower molecular sieve adsorption – one tower dries the gas while the other regenerates, for low dew points.
• Instrument and fuel gas dryers – compact dryers for instrument gas and fuel gas supplies.

• Water dew point, TEG: typically down to −10 °C, or to client specification
• Water dew point, molecular sieve: typically down to −70 °C, or to client specification
• Capacity: skid-mounted for small and medium flows, sized from the gas flow, pressure and water content
• Regeneration: reboiler and still column (TEG) or regeneration heater and cooler (molecular sieve), sized to the duty
• Control: PLC sequencing of tower switching and regeneration, or to client specification
• Pressure vessels: designed to the project's pressure-vessel code, or to client specification
• Materials: selected for the gas composition and design conditions, or to client specification

At wellheads and gathering facilities the skid dries produced gas to the pipeline water dew-point specification before export. It also dries fuel gas for engines, turbines and heaters, and gas feeding CNG stations before compression. Instrument gas dryers supply dry gas to pneumatic instruments and actuators at sites without instrument air.

• Matched to the dew-point target – TEG for pipeline and fuel gas specifications, molecular sieve where a lower water dew point is required.
• Continuous operation – the glycol is regenerated continuously, and the twin towers switch automatically between drying and regeneration.
• Automatic sequencing – PLC sequencing programmed by the Tech Inc. in-house automation team.
• Factory-built – skid-mounted, assembled and tested before dispatch, reducing site work.
• Filters and vessels from one factory – filter elements, housings and pressure vessels are made by Tech Inc.

• Established manufacturer – part of the Davey Group since 1990, exporting to more than 110 countries.
