United Process Systems 6 5/8 x 18' Packed Glycol Contact Tower

The United Process Systems 6 5/8 x 18' Packed Glycol Contact Tower is a specialized industrial vessel designed for natural gas dehydration processes, utilizing triethylene glycol (TEG) to absorb water vapor from gas streams in oil and gas operations. This packed tower features random metal packing (such as Pall rings or similar) to maximize surface area for efficient gas-liquid contact, enabling effective moisture removal in low to medium flow rate applications. Key benefits include compact design for smaller installations, durability in harsh environments, and cost-effective dehydration compared to larger trayed towers. However, drawbacks may include higher pressure drops due to packing and potential fouling in dirty gas streams, as evidenced by organic buildup in used units. This model is non-ASME coded, suitable for non-critical pressure applications, with a presumed MAWP of 1440 psi based on nameplate data. It offers advantages over bubble cap trays in terms of lower initial cost and easier maintenance, though it requires periodic packing replacement. Ideal for upstream gas processing, petrochemical plants, or small-scale dehydration units. Condition analysis from images indicates used status with rust, internal packing intact but fouled with debris and organic growth (e.g., roots or algae), suggesting prior use in a contaminated environment. No visible serial numbers on packing; parent asset is the tower itself, with no attached child assets like sensors. Estimated market price for this used unit is $2,500 - $4,000 USD, based on comparable sales of similar small used contactors on surplus equipment sites. Attached resources: United Process Systems may not have public datasheets; refer to general glycol contactor guides from sources like Emerson or GPSA Engineering Data Book (summary: packed towers for gas absorption, typical flow rates 0.5-5 MMSCFD for this size). For model decoding, '6 5/8' refers to nominal diameter.
