Abstract: Processes, systems and equipment are for treating a digestate resulting from the thin stillage of a bioethanol plant. They can include a decarbonizer system to reduce the carbon and water footprint in an ethanol plant and associated biogas plant by treating a digestate stream resulting from a thin stillage digester. The treatment includes heating the digestate stream to decompose ammonia bicarbonate contained in the digestate stream into ammonium and bicarbonate; and contacting the heated digestate stream with air so that a first portion of the ammonia is desorbed from the heated stream to mix with the air.

Abstract: Wheel covers are removably attached to a spoked wheel vehicle to provide, identity, protection, illumination and audible sound for safety and pride of ownership. The wheel covers are shaped as disks placed on opposite sides of a wheel. Fasteners on each disk engage the spokes of the wheel to secure the wheel covers in place.
