  • Patent number: 7387653
    Abstract: An assembly for cleaning particulates from fluid streams has a primary and secondary centrifuge collectors and may employ negative pressure to produce the fluid stream. The primary centrifuge collector forms an outer vortex to remove larger particles, then an inner vortex to produce higher centrifugal forces upon and to remove a portion of the particulates. In the secondary centrifuge collector, a plurality of secondary centrifuge collector units are present. The partially cleaned fluid stream enters one of the secondary centrifuge collector units, where swirl vanes form an outer vortex. The fluid flow travels along the secondary vortex to the bottom of the secondary centrifuge collector unit, where the direction of the fluid flow is reversed and the fluid flow is subjected to a higher energy inner vortex. The centrifugal forces exerted by these vortices convey the particulates to the walls of the secondary centrifuge units, where the particulates are evacuated initially by gravity for disposal.

    Abstract: A method and apparatus for recycling the bottoms product from an absorber tower back to the absorber tower. However, before the bottoms product is returned to the tower, the solid particles entrained therein are removed via one or more centrifuges closely coupled to the absorber tower. These centrifuges are located adjacent the tower and are elevated with respect to the tower such that their centrate can be directly returned or delivered back to the absorber tower via gravity.

  • Patent number: 5059222
    Abstract: An engine air precleaner which is efficient at both low and high engine speeds as described. The precleaner has two air flow designs incorporated within it: one for a lower velocity of air flow and one for a high velocity of air flow. The dual air flow design is accomplished by an outer tubular sleeve member and an inner tubular sleeve member attached to an engine air intake stack. At low engine speeds, the air flow passes into the precleaner and through the inner tubular sleeve, causing the contaminant removal system to efficiently remove contaminants from the air. When the engine speed is increased, a valve opens allowing air to flow through tubular sleeve. Therefore, the contaminant removal system will operate substantially the same speed whether the engine is running at a lower or higher throttle.
