Apparatus and method for handling liquids or slurries from an oil or gas process

An apparatus for separating non-magnetic solid particles and magnetic swarf particles from a liquid flowing from an oil or gas operation, the apparatus comprising:

• a plurality of magnet assemblies defining an array which traverses a flow path of a liquid from an oil or gas operation, wherein the magnetic assemblies are spatially separated to provide flow spaces between adjacent magnetic assemblies, each magnet assembly having a first condition in which an operable part of the magnet assembly is active to attract magnetic particles to the magnet assembly, and a second condition in which the operable part of the magnet assembly is inactive and magnetic particles are not attracted to the magnet assembly;
• a drive mechanism for moving the magnet assemblies between a position in which they are exposed to the liquid and a collection location;
• wherein the apparatus comprises an activation means which is configured to move the magnet assemblies between the first condition when exposed to the liquid and the second condition when at the collection location,
• characterised in that the plurality of magnetic assemblies are arranged as a conveyor for non-magnetic solid particles wherein movement of the conveyor mechanically conveys non-magnetic solid particles in the liquid to the collection location.
