A triethylene glycol (TEG) dehydration unit bid lives and dies on one number that is easy to overlook: the required outlet water content, usually expressed as pounds per million standard cubic feet or as a water dew point. That single figure drives the contactor design, the glycol circulation rate, the regeneration temperature, and whether you need enhancements like stripping gas or a vacuum system. Miss it or read it wrong, and you size a unit that either fails the guarantee or overshoots the cost.
Why the Dew Point Spec Decides the Bid
The outlet specification is the performance guarantee the buyer will hold you to. A pipeline-quality spec of seven pounds per MMscf is routine; a cryogenic-upstream spec well below that, or a tight hydrocarbon and water dew point, demands a different and more expensive design. The inlet conditions, gas flow, pressure, temperature, and inlet water content, set the duty, but the outlet spec sets the difficulty. A bidder who designs to the wrong target either loses on price by overbuilding or loses on compliance by underbuilding.
Why These Specs Are Easy to Misread
Dehydration tenders bury the numbers that matter in process datasheets and basis-of-design documents, often as one line in a stream table. The inlet and outlet conditions may be on different pages, the dew point may be stated as a temperature at a reference pressure that needs conversion, and the guarantee language may sit in the commercial terms. A bidder skimming for the gas flow can size to the throughput and completely misjudge the moisture target that actually governs the design.
How an AI Bid Response Agent Extracts the Right Numbers
An AI bid response agent reads the full dehydration package and pulls the inlet conditions, the outlet water content or dew point, the flow, pressure, and temperature into one place, with the source page cited. It flags whether the outlet spec is routine or demanding and connects it to the guarantee language in the commercial terms. You size the TEG unit against the correct target on the first read, so your bid meets the guarantee without overbuilding the price.
