A rotating coalescer having an ejected coalesced liquid separating device is described. The separating device prevents re-entrainment of liquid into a stream of filtered gas. The rotating coalescer includes a rotating filter element or coalescing cone stack positioned within a rotating coalescer housing. The outer surface of the rotating filter element or the outlet of the coalescing cone stack is displaced from the inner surface of the rotating coalescer housing. The gap between the rotating filter element or the coalescing cone stack and the rotating coalescer housing allows for ejected coalesced liquid, such as oil, to accumulate on the inner surface of the rotating coalescer housing for drainage and allows for filtered gas, such as air, to exit through a clean gas outlet of the rotating coalescer housing.

A work machine, such as a skid steer loader or a compact track loader, includes an air intake assembly for a heating, ventilation, and air conditioning (HVAC) unit. A conduit integrated into a structure supporting a roof over an operator cab accepts air and water from the atmosphere through an air inlet proximate the roof. A debris outlet downstream in the conduit allows gravity to return the water to the environment. Between the air inlet and the debris outlet, an orifice in the conduit connects to an air duct through which the air may be diverted by suction from the HVAC unit. An air filter at the end of the air duct removes remaining particulates from the air prior to conditioning by the HVAC unit. Sizing the cross-sectional areas of the air path to exceed a cross-sectional area of an inlet to the air filter and providing a substantially straight air path avoids resistance to air flow, resulting in efficient intake of cleaner air.

A control system for turbine systems configured to provide accurate interpretations of detected particle accumulation, improve performance of turbine systems, and/or minimize costs due to downtime and maintenance are disclosed. The control system may build an intelligent model of fluid flow based on measured data provided by a sensor in a fluid flow path of the turbine system. The intelligent model consults a filter efficiency framework and determines an impact value that quantifies an operational efficiency of the turbine system and may identify a location of possible leakage, estimate a total amount of ingress of particles, identify components of the turbine system that may be operating in a diminished capacity, estimate a risk of damage to components of the turbine system, and/or recommend mitigation actions.

A system for removing particulate matter from the gas in a gas discharge laser includes one or more nonwoven screens which are optimized for, among others, manufacturability and feature integration. The nonwoven screens are configured for precisely directing the flow to optimize the separation of particles from the gas flow and provide sufficient surface area for improved dust adherence.

A control system for turbine systems configured to utilize an intelligent model of particulate presence and accumulation within turbine systems to address engine maintenance, erosion, corrosion, and parts failure mitigation is disclosed. The control system may build an intelligent model of fluid flow based on the data value measured by at least one sensor and based on a database of known data values to provide an estimation of amount of ingress of air intake particles into the turbine system, fouling within the turbine system, erosion of at least a portion of the turbine system, and performance degradation rate of the turbine system.

Disclosed is a system and method to separate solid particle components from a fluid. It can be used in close association with a hydrocarbon producing well and uses a novel combination of mechanical filtration, solids decantation, and real and apparent forces. Disclosed is a spherical vessel with a tangential inlet to introduce the fluid and a fluid exhaust and filter arranged on the center line of the interior of the vessel. A combination of pressurized fluid and solid particles enter at the tangential inlet and move primarily in a circular path around the interior of the vessel. The circular path results in the larger mass particles settling at the vessels lower region. Less massive particles may be entrained in the exiting fluid flow toward a filter element where they are removed from the exiting fluid. The vessel has an opening to remove the trapped separated particles.
