Abstract
A method and system are disclosed for actively cooling a fluid, particularly a foamed fluid. The foamed fluid may comprise a foamed suspension of fibers that is used to form a web. The foamed suspension of fibers is fed around a recirculation loop and actively cooled using a heat exchanger.
Claims21
A process for producing a web comprising:
- forming a foamed suspension of fibers;
- depositing at least a portion of the foamed suspension of fibers onto a forming surface for producing a web;
- flowing at least a portion of the foamed suspension of fibers through a recirculation loop;
- and
- actively cooling the foamed suspension of fibers flowing through the recirculation loop, the foamed suspension of fibers being maintained below a preset temperature.
2 more elements
A system for forming a web comprising:
- a mixing tank for holding a foamed suspension of fibers, the mixing tank in fluid communication with a water supply, a surfactant supply, and a fiber supply for receiving and combining water, a surfactant, and a fiber furnish;
- a web forming process configured to receive a foamed suspension of fibers from the mixing tank for forming a web;
- a recirculation loop that circulates a foamed suspension of fibers from the mixing tank and back to the mixing tank, the recirculation loop maintaining the fibers in a foamed suspension;
- and
- a heat exchanger positioned along the recirculation loop for receiving the foamed suspension of fibers, the heat exchanger also being in fluid communication with a cooling fluid supply for receiving a cooling fluid and wherein the foamed suspension of fibers flow through the heat exchanger along a first pathway while the cooling fluid flows through the heat exchanger along a second pathway for cooling the foamed suspension of fibers.
