GENERAL INFORMATION
Closed loop glycol and amine systems pick up solids, oils, dissolved hydrocarbons and well inhibitors from the natural gas stream, fouling the fluids and causing a loss in operating efficiency. Sludge buildup, foaming and contaminate discoloration can account for the loss of glycol to the gas stream or total shut down of the dehydration or sweetening process. A cartridge type fiber filter will remove the solids contaminant, but a charcoal bed is required to remove oils, dissolved hydrocarbons, well inhibitors and degradation compounds form the glycol or amine systems.

The Nowata Filtration activated carbon adsorber, canister type filter is designed to purify glycol and amine streams which minimizes fouling to keep the operating efficiency high. Canister type carbon cartridges are the most economical type of activated carbon absorbers for flow rates up to 1.5 gallons per minute. The canister makes charcoal replacement much easier and cleaner than loose charcoal beds. Canisters keep the operator from handling the messy charcoal. Contaminated spent charcoal is difficult to dispose of unless it is contained in a canister. Nowata Filtration offers one and two canister housings. Each canister contains 34 pounds of granulated charcoal and is rated for 1.5 gallons per minute of flow. In a typical 400 gallon glycol dehydration system a single canister will usually last between 8 to 10 weeks. The glycol should be checked regularly for foaming or discoloration which indicates it is time to change the canister. Unlike fibrous filter cartridges for the removal of solids, a charcoal adsorber canister will not necessarily experience an increase in pressure differential across the unit. Nowata also offers high flow / high pressure charcoal housings that hold up to 14 canisters.

GENERAL INFORMATION
Closed loop glycol and amine systems pick up solids, oils, dissolved hydrocarbons and well inhibitors from the natural gas stream, fouling the fluids and causing a loss in operating efficiency. Sludge buildup, foaming and contaminate discoloration can account for the loss of glycol to the gas stream or total shut down of the dehydration or sweetening process. A cartridge type fiber filter will remove the solids contaminant, but a charcoal bed is required to remove oils, dissolved hydrocarbons, well inhibitors and degradation compounds form the glycol or amine systems.

The Nowata Filtration 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 convenient type of activated carbon absorbers for flow rates up to 20 gallons per minute. The canister makes charcoal replacement much easier and cleaner than loose charcoal beds. Canisters keep the operator from handling the messy charcoal. Contaminated spent charcoal is difficult to dispose of unless it is contained in a canister. Nowata Filtration offers from 1 to 14 canister housings.

Each canister contains 34 pounds of granulated charcoal. In a typical 400 gallon glycol dehydration system, a single canister will usually last between 8 to 10 weeks. Charcoal adsorber filters can be installed directly in the process line, handling 100% of the flow or in a side stream of no less than 30% of the total flow.

Charcoal Replacement Canisters

Ideal for removal of oils and heavy hydrocarbons in gas treatment systems. Easier and cleaner than bulk carbon systems. The 11NC22 canister contains approximately 31 lbs. of granulated activated carbon. In a typical 400 gallon glycol dehydration system, a single canister will usually last between 8 and 10 weeks depending upon the amount of hydrocarbon contained in the natural gas stream.
