Nacah Tech LLC products

Nacah Tech provides the process design, mechanical design, BMS (control system) design, material procurement and fabrication, installation supervision and commissioning of Thermal Oxidizer Systems with many available accessories such as LEL analyzer, flow meters, controls, waste heat recovery, preheaters, flame arrestor, id fan, and stack. Each system thermally decomposes the VOC’s in waste gases from Production facility with its given emission sources in air/gas. The TO system is designed based on the information supplied under the specification. Design, manufacture, deliver & commission TO system for use at a wide variety of industrial, process or other plants.

Recuperative thermal oxidizers best suit VOC laden air streams with sufficient loading that provides more heat than for sound RTO’s operation but insufficient normal loading for DFTO (direct fired thermal oxidizer). Recups reduce the operating costs to an optimum level while not overheating or overloading the system.

In a Fluid Bed Concentrator System, exhaust enters through a series of perforated trays containing media. The media adsorbs VOCs and is continually removed from the trays, regenerated, and returned.

Popular for higher VOC concentrations, thermal oxidation will combust the VOC gases to achieve very high levels of purity of the vented air. Obvious advantages are non-replacement of the spent carbon bed.

All VOC generating points such as oil sumps, storage tanks for slop and feed oils, separator tanks like API’S, TPI’s, DAF systems, etc. need to be fitted with the VOC control system. This control may be either by Carbon adsorption and subsequent desorption, or by use of thermal oxidiser systems, to ensure that the vapours escaping from these units are controlled to contain the VOC’s.
