Product Overview
Available for sale is a skid-mounted hot oil heat exchanger process module removed from a professionally engineered modular condensate stabilization and natural gas liquids (NGL) recovery facility in Heurfano Mountain New Mexico. The package features dual Doyle & Roth shell-and-tube heat exchangers mounted on a common structural skid with associated circulation equipment, insulated process piping, electric motor-driven pumps, valves, two heat exchanger columns (not pictured) and instrumentation as pictured along with the Chart Cooling condenser and a small vessel that is also on this process module.
Originally designed for continuous industrial service, this skid-mounted process module offers an excellent opportunity for inspection, refurbishment, repurposing, or integration into oil & gas, petrochemical, or other industrial process applications.

This was removed from a modular natural gas processing facility that was shut down due to declining field production and changing market conditions. The plant remained operational at the time it was taken out of service. The equipment has since been stored at our facility in its current as-removed condition and is available for inspection.
