Replacement Nowata 11NC22 Charcoal Adsorber Canisters for amine and glycol process purification

MeiTong 11NC22 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 Nowata 11NC22 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 11NC22 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.

Core Functions of Activated Carbon Canisters

Efficient Adsorption and Purification: Granular activated carbon canisters remove adsorbable contaminants, organic impurities, color bodies, and foam-forming substances from process liquids through physical and chemical adsorption.

Liquid Polishing and Decolorization: Designed to improve fluid quality by reducing color and adsorbable contaminants in process liquids, including triethylene glycol (TEG) and amine solutions.

Foaming Control: Helps remove foam-forming contaminants from amine and glycol solutions, supporting stable operation of downstream processing equipment.

Filtration Mechanism & Flow Direction

The activated carbon canister features an outside-to-inside flow design, allowing contaminated liquid to pass through the granular activated carbon bed for effective contact and adsorption.

Liquid Inlet: Contaminated process liquid enters the canister through the perforated outer shell.

Adsorption: As the liquid flows through the granular activated carbon bed, targeted hydrocarbons and adsorbable organic contaminants are captured through the adsorption process.

Treated Liquid Outlet: The purified liquid enters the perforated central core and exits through the designated outlet.

Activated Carbon Fines Retention:An internal fabric liner helps retain activated carbon fines and reduce carbon particle migration into downstream process equipment, supporting cleaner operation of the filtration system.

Operating & Installation Requirements

Compatible Filter Housing: The activated carbon canister must be installed in a compatible charcoal adsorber housing designed to accommodate the canister dimensions and flow configuration.

Upstream Particulate Filtration: A suitable upstream particulate filter is recommended to remove suspended solids before the liquid enters the activated carbon canister. This helps reduce solids loading on the carbon bed, maintain adsorption performance, and potentially extend service life.

Application :Typical uses for oil and gas operations include Amine and Glycol purification, Hydrocarbon adsorption, Wastewater treatment ,Boiler feed water treatment.

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 .
