Polymer blending system
View Patent ↗A system for blending polymers and other chemicals in an aqueous liquid is provided. Static mixers and tubes, preferably in one or more tube bundles, provide a volume sufficient to allow a residence time in the system to hydrate a polymer. Static mixers may be integrated with a tube bundle. The system may be mounted on a portable base such as a trailer. The concentration of polymer and chemicals in water may be controlled by a controller. A variable speed electric pump may be utilized to precisely control the amount of polymers or other chemicals added to the aqueous liquid.
1. A portable system for blending one or more chemicals into a flow of fluid comprising:
1) a trailer including a coupling for attachment to a towing vehicle,
2) a trailer bed in the form of a storage tank,
3) a plurality of wheels attached to the trailer,
4) one or more storage tanks for the chemicals to be blended,
5) a variable speed electric pump having an input and an outlet for the chemicals to be blended,
6) a diesel electric generator and a fuel storage tank on the trailer,
7) a tube bundle located underneath the trailer bed having an input and outlet for the fluid and an inlet for the chemical to be blended, and
8) a controller for controlling the speed of the variable speed electric pump.
2. A portable system as claimed in claim 1 further including a barrier along the periphery of the trailer bed which forms a leak free spill structure that encloses the liquid tanks.
3. A portable system as claimed in claim 1 wherein the tube bundle includes a plurality of straight sections interconnected by elbow sections, and the straight and elbow sections lie in a common horizontal plane.
4. A portable system as claimed in claim 3 wherein the tube bundle further includes a plurality of static mixers.
