National Tank Company Horizontal Filter Separator, 24" x 7', 1395 PSI

The National Tank Company (NATCO) horizontal filter separator is a robust industrial vessel designed for removing liquids, solids, and mists from natural gas streams in oil and gas processing, petrochemical, and refinery applications. Built in 1993, this ASME-certified unit features a cylindrical carbon steel construction with internal components including filter cartridges, a vane mist extractor, and level control mechanisms visible in the provided images. Key benefits include high-efficiency separation to protect downstream equipment, compliance with high-pressure standards up to 1395 PSI, and a compact footprint suitable for medium-flow operations. Advantages over competitors like Perry or Peerless separators include NATCO's proven durability in harsh environments and ease of maintenance with standard 4" flanged connections. Drawbacks may include potential corrosion due to its used condition, as evidenced by external rust and dirt accumulation, requiring refurbishment for optimal performance. Overall, it offers cost-effective gas conditioning, reducing operational downtime and extending equipment life, though age-related wear could increase inspection needs. This unit appears to have been used in field operations, with no visible major damage but some internal residue.
