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 also offers low flow 1 and 2 canister housings.  
See the 1 and 2  Charcoal Canister models for description of low flow rate adsorbers.

Each canister contains approximately 31 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.
