Deoiling Hydrocyclone Skid

• TI-HCY50 – deoiling hydrocyclone skid, with the liner count set by the design flow.
• Single-vessel or multi-vessel skids – vessels arranged so that liners can be isolated for turndown.
• Pumped feed option – a booster pump on the skid where upstream pressure is low.
• Spare liner positions – vessel capacity reserved for higher water rates later.

• Flow: sized to the duty, with liner count chosen for design flow and turndown, or to client specification
• Driving pressure: from the upstream separator or a booster pump, to client specification
• Reject flow: set by PDR control to suit the inlet oil content
• Outlet quality: to suit the downstream flotation, filtration or injection specification
• Vessels: designed to ASME VIII or client specification
• Materials: carbon steel or duplex stainless steel vessels with corrosion-resistant liners, or to client specification
• Rotating equipment: where fitted, proven pumps from leading makers, packaged on a skid designed and built by Tech Inc.

Does it need a pump?
Usually not. It runs on the pressure from the upstream separator, and a booster pump is fitted only where that pressure is too low.

How is the reject controlled?
By pressure differential ratio (PDR) control, set to suit the inlet oil content.

How is turndown handled?
The number of liners is chosen for design flow and turndown.

Which materials are used?
Carbon steel or duplex stainless steel vessels with corrosion-resistant liners, designed to ASME VIII.

Deoiling hydrocyclones take the bulk of the dispersed oil out of produced water directly downstream of the production separators, ahead of gas flotation and nutshell filtration. Their small footprint and low weight make them a common choice on offshore platforms and compact onshore facilities, and on water-injection projects where water rates rise over field life.

• No moving parts – line pressure drives the separation, which limits maintenance to liner inspection.
• Small footprint – high separating force in compact vessels suits platforms and tight plots.
• Turndown by isolation – liners or vessels can be taken out of service as flow changes.
• Fast response – short residence time and PDR control handle swings in inlet conditions.
• Expandable – spare liner positions allow for higher water rates later in field life.
