Developed in-house by our expert engineering staff, the Romar-Abrado Swarf Handling System incorporates years of specialist knowledge, experience, and operational expertise as a global provider of magnetic separation technologies to the oil and gas industry.
Designed with efficient metal particle separation and manual handling safety at its core, the Romar-Abrado 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 ensures the effective removal of metallic contaminants from the drill fluid, with two stages utilising Romar-Abrado patented magnetic separation technology. Capable of operating at flow rates of up to 1,500gpm, while recovering debris at up to 2,000 kg/hr, the Romar-Abrado Swarf Handling System allows the full optimisation of milling parameters which reduces time and costs for our clients.
The patented Chain Link MAGNOVEYOR® separation and recovery unit lies at the heart of the Romar-Abrado Swarf Handling System. Comprising a vertical array of partially submerged pipe ‘loops’, each 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 circulate 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 release the particles into the collection chute as the chain of magnets enter 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.
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, which is one of the key performance differentiators of the Romar-Abrado 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 and leading to the accumulation of debris in the void immediately below the drill floor.
Romar-Abrado 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.
Located between Aberdeenshire and Louisiana, Romar-Abrado enjoys a global presence. Operating across six continents, we offer a unique and effective service to clients worldwide.
