Abstract: The disclosure is directed toward methods for delivering a pigment dispersion and an inverted retention aid emulsion to a papermaking process. The method comprises injecting the pigment dispersion and the inverted retention aid emulsion into a process line of the papermaking process. The pigment dispersion comprises titanium dioxide, and the retention aid may comprise an anionic flocculant. The process line is located downstream from a screen and upstream from a headbox. The methods may incorporate the use of one or several nozzle devices.

Abstract: A method of rapidly and essentially simultaneously creating and feeding a dispersion into a hydrocarbon process stream. This method allows for the effective use of chemical additives in a hydrocarbon process line that are highly unstable or that are very difficult to disperse. This is especially helpful in hydrofracturing operations as the very rapid flow rates require very fast dispersion formations. As a result the method allows greater fracking pressures which can be obtained with lower energy inputs and by using lessor amounts of chemical additives. As a result hydrocarbon extraction can be accomplished in a manner which is both more environmentally friendly as well as less expensive.

Abstract: The invention provides a method and apparatus for optimally feeding an ASA emulsion into a papermaking process. An intense transmission of ultrasonic energy rapidly and efficiently forms an ASA emulsion. Nearly simultaneous to forming the emulsion, the emulsion is fed into a high-speed dual conduit feeding apparatus, which quickly mixes the ASA emulsion with other chemicals and feeds the mixture directly into a papermaking process. The invention operates so fast that virtually no hydrolysis of the ASA occurs. This both prevents damage to the papermaking machinery and improves the quality of the produced paper. The invention operates 10-20 times faster than mechanical based emulsion methods and requires 1/7 as much energy to operate. The invention also self-monitors the process and can automatically correct any detected problems with the fed ASA emulsion.
