  • Publication number: 20240140844
    Abstract: Disclosed herein are well treatment composition and methods. In a specific embodiment, a well treatment composition includes: denatured algae, where the denatured algae have a protein content from about 20.0 wt % to about 90.0 wt %, and where the denatured algae have a lipid content from about 0.1 wt % to about 30.0 wt %; one or more carrier fluids; and one or more additives. In another specific embodiment, a method of making a well treatment composition can include contacting one or more algae with one or more denaturants to make a denatured algae, where the denatured algae have a protein content from about 20.0 wt % to about 90.0 wt %, and where the denatured algae have a lipid content from about 0.1 wt % to about 30.0 wt %; and contacting the denatured algae with one or more carrier fluids to make a well treatment composition.

  • Patent number: 11739253
    Abstract: Proteinaceous enhanced oil recovery operates on the principle that proteins can be denatured using chemicals to break them down into a viscous polymeric mixture that exhibits an EOR effect. In one or more embodiments, the proteins in question are sourced from an algae (spirulina) meal, which could be obtained as a waste product from wastewater treatment or bioprocessing operations, including biofuel production where the lipids are extracted for fuel but the large volumes of proteins are considered a waste material with little or negative value. In other embodiments, other biomasses are used, especially edible biomasses, thereby mitigating public resistance to drilling operations due to concerns of perceived toxicity of chemicals. This also mitigates legal liability from the use of chemicals that are known to be toxic. Additionally, the agents are denatured biomasses that have not undergone expensive purification or separation steps. This will make these agents highly cost competitive.

  • Publication number: 20210316029
    Abstract: A method and device for treating contaminated or potentially contaminated items is provided. The method will include the steps of placing the items in a reactor. The reactor is then sealed and ozone or ozonated gas is sent into the reactor. The items are held in the reactor long enough to complete the decontamination process. The reactor is then opened. Next there is a period of passive reaction so that the ozone can be degraded from the pores and surfaces of the items. The device provided herein includes a reactor, an ozone generator, a rack for holding said items; and a monitor for determining the level of ozone in the reactor.

  • Publication number: 20210308312
    Abstract: A rack for sanitizing or cleaning medical or personal protective equipment is claimed herein. The rack has at least two stringers that run the length of the rack. The rack has at least two vertical grates that are spaced apart from each other along the stringers. The spacing between the grates will be sufficient such that a standard respiratory mask (e.g. N95) may be placed between two adjacent grates and be held in a vertical orientation.
