C Series High Flow Models – Adsorbents
Closed loop glycol and amine systems will pick up solids, oils, well inhibitors and dissolved hydrocarbons from the natural
gas stream, fouling the fluids and causing a loss in operating efficiency. Sludge buildup, foaming and fluid discoloration are indications that fouling has occurred.
This can mean loss of glycol to the gas stream or total shutdown of the dehydration or sweetening process. A cartridge type fiber filter will remove the solid contaminants, but a charcoal bed is required for removal of the oils, dissolved hydrocarbons, well inhibitors and degradation compounds from the glycol or amine systems.

The C series (formerly Nowata) activated carbon canister type adsorber is designed to remove entrained hydrocarbons from glycol and amine streams which eliminates fouling and maintains operating efficiency.
Canister type carbon cartridges are the most economical type of activated carbon adsorbers for flow rates up to 20 gpm. Because the charcoal is contained inside the canister, charcoal replacement is easier and disposal much cleaner than loose charcoal.
• Standard sizes: 4, 6, 10 and 14 canister models (1 and 2 canister models also available)
• 4 canister model – 150 psi working pressure
• Larger models – 150 psi working pressure (Larger sizes and higher pressure models available)
• Bolted closure for fast, easy canister replacement
• Convenience of containerized carbon rather than bulk
• Buna o-ring standard, other seal materials available
• Glycol/Amine flow rates to 20 gpm
• Carbon steel construction standard
• Epoxy lined carbon steel offered
• Stainless steel construction also available

Max. Pressure = Maximum allowable non-shock pressure
Max. Flow Rate = Recommended maximum flow rate of glycol or amine. For charcoal to operate properly, the velocity of the fluid through the media should be relatively low. Flow ratings are based on dwell time in the carbon rather than velocity induced pressure drop across the canister. Oversizing the filter will provide more efficient removal of contaminate.
C series housings are constructed of all carbon steel with plated carbon steel internals. Post weld heat treatment (stress relieving) is available on special order for sour service.
Stainless steel construction is also available.
The standard Buna o-ring seal will operate to 220 °F. Viton and Ethylene Propylene seals are available for special service. For best hydrocarbon removal efficiency, the operating temperature should be held below 120 °F.
Inlet and outlet connections are available in sizes other than standard to fit customer requirements. Internal pipe thread drain and vent connections are provided as standard. ANSI flanges, external pipe thread, or non-standard sizes are available by special order.
Special purpose connections such as relief valve fittings and pressure taps are available to meet specific requirements. Non-standard connection location, unusual mounting heights or dimensions are also available.
Special Pressure Ratings
The standard four canister housing is rated for a working pressure of 150 psi. Standard pressure rating of the larger housings is also 150 psi. All C series housings are designed with a 1/32” corrosion allowance as standard. Also, special pressures and greater corrosion allowances are readily available.
Several items are available to monitor or control filter operation. Differential pressure is not an indication that the carbon canister needs to be replaced. Therefore, a differential pressure gauge is not recommended for charcoal vessels. A pressure gauge, located in the vent connection, is an important safety device used to protect the operator from inadvertently opening the vessel closure under pressure. A vent valve should be installed to remove air trapped during canister replacement.
ASME Code Construction
The C series filters are designed in accordance with the Boiler and Pressure Vessel Code of the American Society of Mechanical Engineers. When required, each housing unit can be stamped with the U symbol, denoting fabrication and testing performed by specific procedures.
