Abstract:
1. A system for measuring the oil-absorbing capability of porous materials comprising of: (a) a container to hold mixture of oil and water, (b) an oil reservoir to hold oil, (c) an air reservoir to hold compressed air, (d) an oil injection system that includes the oil reservoir and controls for addition and removal of oil from the container, as well as a control to alter the rate of addition and removal of oil from the container, (e) an air injection system that includes the air reservoir, and controls for addition and removal of air into the container, as well as a control to alter the rate of addition and removal of air from the container, (f) a container motion control system that creates complex motion trajectories for the mixture in the container while ensuring that the porous material is fully, or partially submerged in the oil and water mixture in the container, and (g) a porous material motion control system that creates complex motion trajectories for the porous material under test so that the porous material is at all times within the container.
