7NC20 Charcoal Adsorber Canister | Nowata Compatible Replacement

MeiTong 7NC20 Activated Carbon Canister is designed for liquid-phase hydrocarbon adsorption and purification in oil and gas processing, amine treatment, glycol dehydration, and industrial water treatment systems.

As a compatible replacement for the Nowata7NC20 charcoal canister, this cartridge contains granular activated carbon within a rigid perforated metal shell and central core. Its enclosed design simplifies carbon replacement, reduces direct handling of loose activated carbon, and makes spent carbon easier to collect, transport, and dispose of.

Unlike conventional particulate filter cartridges, the 7NC20 activated carbon canister removes targeted hydrocarbon contaminants and organic impurities primarily through adsorption rather than mechanical particle filtration.

Designed for use in compatible charcoal adsorber housings, it provides a practical solution for maintaining process fluid quality and supporting reliable operation of industrial filtration systems.

Adsorption Mechanics

Outside-to-Inside Radial Flow: Fluids pass through the outer support and migrate radially inward toward the perforated core, ensuring maximized contact time with the carbon media.    

Adsorption Purification: Soluble contaminants, organic impurities, pigments, and foaming agents are captured within the microporous structure of the activated carbon molecules via physical and chemical adsorption.  

Effluent Polish & Color Removal: Efficiently removes color bodies and contaminants (e.g., in Triethylene Glycol and Amine systems) to restore fluid quality and prevent process foaming.  

Activated carbon filter elements and carbon canisters are widely utilized across demanding industrial sectors for deep purification, decolorization, and contaminant removal. 

Key application fields include:

1. Gas Processing & Sweetening Systems

Amine Sweetening Units: Effectively handles amine solutions (such as MEA, DEA, and MDEA) to eliminate antifoam agents, accumulated hydrocarbons, and thermal degradation products.

Glycol Dehydration Systems: Removes color bodies and impurities from triethylene glycol (TEG) and other glycols utilized in natural gas processing.

Acid Gas Removal Solvents: Purifies process solvents in specialized acid gas removal systems, including Selexol and Sulfinol processes.

2. Petrochemical Industry

Refinery Process Fluids: High-efficiency purification of refinery process fluids and hydrocarbon liquids.

Chemical Process Liquids: Deep purification and filtration of various chemical process liquids and specialty solvents.

Condensate Treatment: Industrial oil purification and process condensate treatment.

3. Chemical Manufacturing

Organic Solvent Purification: Deep purification of high-purity organic solvents and chemical solutions.

Process Water Treatment: Process water purification and targeted removal of trace organic pollutants.

Decolorization & Deodorization: Essential decolorization, deodorization, and organic impurity removal during chemical production processes.

4. Industrial Lubricants & Water Treatment

Industrial Lubricating Oils: Refining, decolorization, and micro-filtration of industrial lubricating oils and petroleum-based oil products.

Produced Water Treatment: High-efficiency removal of trace organic pollutants, foaming agents, and impurities in industrial process water and oilfield produced water.

Premium Virgin Activated Carbon: Filled with 100% virgin coal-based granular activated carbon (8x30 mesh) processed via high-temperature steam activation, maximizing adsorption sites for both high and low molecular weight impurities.

Durable Heavy-Duty Construction: Built with perforated plated steel inner core and outer support, plated steel end caps, polymer-based gaskets, and a stainless steel cable handle for easy installation and removal.

High-Capacity Adsorption: Optimizes contact time and removal efficiency for heavy hydrocarbons, color bodies, and surface-active contaminants.

Dual Protection Covers: Features cotton core covers and outer covers to retain carbon particles and prevent carbon fines from shedding into the effluent stream.

Foaming Prevention: Protects amine and glycol dehydration/sweetening systems by continuously stripping out degradation byproducts that cause foaming and operational upset.

High Operational Tolerance: Operates effectively at temperatures up to 300°F (149°C) and handles maximum differential pressures up to 90 psid (6.2 bar).

Direct OEM Compatibility: Designed for vessel housings that accommodate one or multiple activated carbon canisters, with the process fluid entering the canister from the top. Common manufacturers of these filter housings include Nowata, Jonell, PECO Series 10 filter vessels , Exterran, Valerus, Hanover, Smith, Global Vessel, and KW International competitor housings
