A single propane engine powers a hydraulic pump, with fluid being routed to three separate hydraulic motors with associated control valves to provide for forward/reverse locomotion, bidirectional paddle mixing, and vacuum generation. The dust collection system is preferably a two-stage system including a vacuum collection tank and a HEPA filter.

Abstract: A compact rotating fluid stabilizer and multiphase separator system separates a multiphase input fluid flow and delivers single phase liquid streams at elevated pressure from inlet conditions. A separator housing with a lower separation chamber and an upper separation chamber rotates about a central axis. The input flow is received into the lower separation chamber and centrifuged into its constituent phases. A gaseous phase migrates through a rotary structured packing up a center tube and exits through a discharge pipe atop the housing. A heavy liquid phase is delivered at high pressure through a first diffuser ring with permeable gas tip seals supplied by high pressure gas. A lighter liquid phase migrates over a weir into an upper separation chamber and is delivered to a second diffuser ring. The compressor reduces vapor pressure to stabilize the light liquid phase.
