Abstract

An apparatus for collecting floating marine debris comprises a frame, a debris collection container in communication with a rear opening of the frame, a pair of helicoidal screws mounted to the frame in a symmetrical V-arrangement that tapers inwardly from a front opening of the frame to the rear opening, and at least one prime mover rotationally coupled to the pair of helicoidal screws. The prime mover is operable to rotate the helicoidal screws in opposite directions at the same angular velocity in water to move the apparatus forward through the water, such that floating marine debris enters the apparatus through the front opening, passes through the rear opening and is collected in the debris collection container.

Abstract

The present disclosure relates to systems and methods for recovering mature fine tailings (MFT) from oil sands tailings ponds. Some examples include a hollow, fully enclosed around its perimeter, ideally of cylindrical form, open bottom structure (a hollow conduit), of predetermined geometry, which is placed at the pond surface. The hollow conduit can penetrate MFT deposits to or below a level at which MFT of required density is located. A width or diameter of the hollow conduit can be determined with respect to the MFT inflow velocity and the corresponding shear rate, so as to enable MFT flow into the hollow conduit at a rate matching a rate at which the MFT is removed from the pond (e.g., a recovery rate). An MFT fill level inside the hollow conduit can be kept constant and equal to a required fill level throughout MFT recovery operations. MFT can enter the hollow conduit during MFT recovery operations solely under action of hydraulic head pressure. MFT can be transferred from within the hollow conduit utilizing a mechanical device such as a pump or a siphon, for transfer to shore based facilities and further processing.
