ROMAR Swarf Managment System

Swarf Management System: 

Smart thinking  blended with practical design. 

Developed in-house by ROMAR’s own engineering staff, The ROMAR® Swarf Handling System incorporates the cumulative knowledge, experience and operational expertise amassed over several years as a specialist provider of magnetic separation technologies to the oil and gas industry.t.


Designed with efficient metal particle separation and manual handling safety at its core,The ROMAR® Swarf Handling System provides a safe, highly efficient solution for the processing of liquids or slurries contaminated with metallic particles.

A three stage swarf separation and recovery process, two of which involve the use of ROMAR® patented magnetic separation technology, ensures the effective removal of metallic contaminants from the drill fluid. Capable of operating at flow rates of up to 1,500gpm while recovering debris at up to 2,000 Kg/hr, the The ROMAR® Swarf Handling System allows the full optimisation of milling parameters. Thus saving our clients rig days and considerable expense.



Larger particles of metallic and non-metallic waste are removed as the drilling fluid passes through the optional ‘scalping’ unit attachment prior to entering the flow trench of the Magnoveyor® unit. This unit directs well fluid through a coarse ‘grill’ located within an acutely angled section of large bore pipe at the top of the unit.

The change in well flow direction accompanied by the physical interference of the metal grill causes larger particles of waste (non-metallic as well as metallic) to fall out of suspension and drop down to a collection chute prior to the drilling fluid being passed through to the Magnoveyor® unit for further processing.


The patented Chain Link Magnoveyor® separation and recovery unit lies at the heart of Romar’s Swarf Handling System on surface. Comprising of a vertical array of partially submerged pipe ‘loops’.  Each pipe loop contains a ‘chain’ of high powered magnets which attract the metallic particles contained within the well fluid to the outside of the pipe. These enclosed magnets constantly circulates around each loop causing the metallic particles on the outside of the pipe to be transported along the outside of the pipe before being released into a collection chute and discharged into a skip. 

The Chain Link MAGNOVEYOR® incorporates a series of ‘blank’ non-magnetic sections within each chain which releases the particles  into the collection chute as the chain of magnets enters the enclosed drive chamber at the top of the loop. The collected metallic particles on the outside of the pipe housing are prevented from travelling further around the pipe loop as the chain within the pipe loop arrives at the drive enclosure face plate at the top of the unit. As the magnet section enters the drive enclosure housing and the subsequent non-magnetic section of the chain arrives, the pipe loop at this point is no longer magnetised and the metallic particles release from the outside of the pipe and fall into the collection chute below.


After passing through the MAGNOVEYOR® processing stage, the drilling fluid is subjected to a final ‘polish’, passing through am EZ-Clean® grid of high strength ditch magnets in order to ensure the complete removal of metallic swarf fragments prior to the mud being passed through to the rig shaker system. The ‘EZ-CLEAN MAGNOROD® system is a high strength magnetic separation system comprising an array of magnetic rods that sit vertically within a frame which is positioned across the flowline. The magnetic rods within each frame form an interconnecting and uninterrupted magnetic field across the entire flow area of the fluid path, thereby creating a highly effective metal particle separation system.

A key element in maximizing the performance of any swarf handling system is ensuring metallic particles remain in suspension up to the point that they enter the separation process. This rather obvious statement of fact highlights one of the key performance differentiators of the ROMAR Swarf Handling System®. Immediately prior to its arrival at surface, the drilling fluid is channelled through the rig’s diverter system and as the available flow area increases the well fluid velocity decreases causing heavier particles to fall out of suspension, leading to the accumulation of debris in the void immediately below the drill floor. ROMAR® patented FLOW HEAD DIVERTER system addresses this problem by ensuring that a continuous, uniform conduit to surface is established and fluid flow velocities are maintained whilst the drill fluid is directed towards the separation processing equipment on surface.
