Economic Feasibility Of Mixed Plastic Waste Pyrolysis Using Twin Reactor System In Northwest Arkansas, Carol Rogers, Patricia Means, Renato Gonzalez, Kaida Sheets, Hayden Townsend
Economic Feasibility Of Mixed Plastic Waste Pyrolysis Using Twin Reactor System In Northwest Arkansas, Carol Rogers, Patricia Means, Renato Gonzalez, Kaida Sheets, Hayden Townsend
Chemical Engineering Undergraduate Honors Theses
Plastic waste generation is increasing at an unsustainable rate while recycling solutions remain stagnant. As a chemical means of recycling, mixed plastic waste pyrolysis can generate synthetic oil appropriate for use as fuel in power generation from plastic waste that otherwise accumulates in landfills. With the scaling of a commercial plastic pyrolysis process in Northwest Arkansas (NWA) modeled after an operational sawdust pyrolysis unit in Huntsville, Arkansas, economic analysis resulted in 26.3% internal rate of return. Therefore, construction of a commercial mixed plastic-to-fuel pyrolysis plant is economically justified and should be pursued. To effectively implement the proposed design, NWA must …
Removal Of Carbamazepine From Drinking Water, Zachary Wiese
Removal Of Carbamazepine From Drinking Water, Zachary Wiese
Chemical Engineering Undergraduate Honors Theses
Due to the increasing prevalence of prescription medication over the past few
decades, pharmaceuticals have accumulated in various water sources. This has become a
public health concern because many pharmaceuticals have limited research on the effects
of chronic low-level exposure. According to the World’s Health Organization (WHO),
traces of pharmaceuticals products have been reported in different water sources such as
surface waters, wastewater, groundwater, and drinking water.[1] One pharmaceutical of
interest that has been detected in water sources is carbamazepine. Carbamazepine is a
common pharmaceutical prescribed for the treatment of seizure disorders, neuropathic
pain, and various psychological disorders. It’s mechanism …
Sulfate Removal From Mine Impacted Waters, Luis Sagarnaga
Sulfate Removal From Mine Impacted Waters, Luis Sagarnaga
Chemical Engineering Undergraduate Honors Theses
Woo Pig Sulfate (WPS) has developed two methods for reducing levels of calcium sulfate in mine impacted waters, a “hot process” and a two-stage nanofiltration process. Both processes were designed to treat gypsum saturated water that is currently being pumped via interceptor wells to prevent the spread of a sulfate plume into a nearby community. Each solution was designed for Freeport McMoran’s Sierrita mine in Green Valley, Arizona, which was visited in order to gain insight about the problem. Below 250 ppm on the treated stream, nanofiltration and the hot process achieve overall recoveries of 84 and 99%, respectively. The …
