Technical Specs-1_.pdf

This document is a technical specification sheet for carbon adsorption cells used in aircraft painting operations.

The document describes carbon adsorption cells as equipment designed to remove solvents and contaminants from exhaust streams in aircraft painting facilities. In typical operations, cells require regeneration every 6 to 12 months depending on usage frequency. The document outlines three primary methods for handling cell regeneration: contracting off-site regeneration services with cells stored on pallets and delivered to third parties; opening cells on-site and emptying them into drums with replacement carbon loaded back into the cells; or installing an on-site regeneration system for frequent regeneration needs. The document notes that third-party regeneration services are the most cost-effective alternative, with regeneration costs less than one dollar per pound, and allow operators to focus on core business processes while avoiding the need for additional permits and thermal oxidation system maintenance.

The document provides detailed regeneration methodology, explaining that steam regeneration recovers solvents through desorbtion and condensing processes, while hot air regeneration requires modest temperatures of 160°F or higher for effective desorbtion followed by thermal incineration. A specifications table lists four carbon cell models (217-071, 217-072, 217-074, and 217-076) with varying dimensions ranging from 20" to 24" in width and height, depths from 3" to 4", pressure losses of 1" to 1.38" water column, consistent face velocity of 125 FPM, and CFM ratings of 350 to 500.
