Abstract
Official abstract text for this publication.
A process includes: (a) providing a powder containing hydrophilic particulates and hydrocarbon liquid; (b) providing polyolefin beads; and (c) forming a combination by combining the polyolefin beads with the powder.
First claim
Opening claim text (preview).
The invention claimed: 1. A process comprising: (a) providing a powder comprising hydrophilic particulates and hydrocarbon liquid; (b) providing polyolefin beads consisting of one or more than one polyolefin; and (c) forming a combination by combining the polyolefin beads with the powder wherein the hydrophilic particulates are water soluble. 2. The process of claim 1 , further comprising allowing the combination to exist for a period of time and then removing the polyolefin beads with at least a portion of the hydrocarbon liquid bound thereto. 3. The process of claim 2 , further characterized by the polyolefin beads having a larger dimension than the hydrophilic particulates and further comprising sieving the combination to separate the smaller hydrophilic particulates from the polyolefin beads. 4. The process of claim 1 , further characterized by the powder comprising the hydrophilic particulates in an amount of at least 95 wt % based on total weight of the powder. 5. The process of claim 1 , further characterized by the polyolefin beads on average having a largest dimension of greater than two millimeters and the hydrophilic particulates having a largest dimension of less than two millimeters. 6. The process of claim 1 , further characterized by heating the combination formed in step (c). 7. The process of claim 1 , further comprising agitating the combination formed in step (c) thereby intermixing the hydrophilic particulates and polyolefin beads. 8. The process of claim 1 , further characterized by the combination comprising less than two weight-percent of the hydrocarbon liquid based on the combination weight. 9. The process of claim 1 , further characterized by the hydrocarbon liquid being present in the powder at a concentration of less than one weight-percent based on total powder weight.
