Injection water, produced water, amine and glycol loops, condensate, and catalyst duty: Gopani engineers elements for the solids loads and temperatures that finish off commodity cartridges, with twin-pod housings that keep the process running through every change-out.
Where we are specified
Injection and produced water
Solids control for injection wells and produced water handling, with Clarysorb OFW removing up to 99 percent of dissolved and dispersed hydrocarbons from water streams.
Rich amine and glycol loops
Particulate control that protects against foaming, solvent losses, and exchanger fouling in gas sweetening and dehydration circuits.
Condensate and lube oil
Condensate dewatering support and lubricant filtration that keep rotating equipment inside its oil cleanliness spec.
Catalyst and high temperature duty
Clarysynt sintered metal elements for catalyst filtration and hot service where polymer media cannot survive.

What stops amine foaming in gas sweetening units?
Foaming is usually driven by particulates and hydrocarbon carry-in that accumulate in the amine loop. Correct filtration on the rich amine stream, sized for the real solids load rather than a nominal figure, removes the stabilising particles, protects the solvent inventory, and keeps the contactor performing. We size these systems from your loop data, and quote element life you can hold us to.
How do you remove hydrocarbons from produced water?
Clarysorb OFW oil-adsorbing media removes up to 99 percent of dissolved and dispersed hydrocarbons, ahead of discharge or reinjection. For free oil, coalescers do the bulk separation first; the combination meets discharge limits without chemical dosing.
What has to come out of produced water, and in what order?
Produced water separated from oil and gas processing can carry residual gases and one or more of free oil, emulsified oil and soluble oil, meaning hydrocarbons dissolved in the water. Coalescers and bulk removal take the free oil first. Clarysorb OFW then binds the dispersed and dissolved hydrocarbons by adsorption: surface-modified fibre on a polypropylene core and end caps, protected by polyethylene netting. The water can then be discharged or reused as process water.
Why filter glycol and amine loops at all?
Contaminants in the glycol system cause foaming and solvent losses, and the same particulates stabilise foam in amine sweetening and tail gas treating units. Filtration on these loops protects the solvent inventory, keeps reactors and contactors efficient for longer, and helps refiners hold product specification with less reprocessing.
Can elements survive offshore and high-temperature duty?
Media and construction are matched to the service: glass fiber Clarywound to 350 C, Clarysynt sintered metal beyond that and into aggressive chemistry, twin-pod Clary-T housings so one side stays in service while the other changes out. Continuous duty is an engineering requirement we design for, not a brochure claim.
One problem loop. That is all we need.
The amine circuit that foams, the injection water that plugs, the element that lasts a week. Send the data; we will engineer the fix and prove it with a trial.
