A sulfur trap provides separation of elemental molten sulfur from a process stream comprising a mixture of sulfur and associated tail-gases. The sulfur trap comprises a vertically-oriented cylindrical wall having a chamber for receiving the process stream, a float positioned in the chamber, the float attached to a float end of a lever, a nozzle insert attached to the distal end of the lever, and a lever fulcrum positioned intermediate the lever float end and the lever nozzle insert end. The float, lever, nozzle insert and outlet are constructed to allow the float position to control nozzle insert engagement of the outlet, particularly to close the outlet when the float is elevated by molten sulfur and to disengage from the outlet to allow discharge flow of liquid sulfur at a determined level of sulfur within the chamber. Embodiments of a method of separating liquid sulfur from gases are also provided.

An oil separator includes a cover attached to an opening portion on a discharge side of a compressor, a discharge flow path formed in an inside of the cover, and an oil separation portion configured to separate an oil from a fluid that has flowed out from the discharge flow path. A dividing wall portion partitions an internal space facing the opening portion into a plurality of spaces. The dividing wall portion is provided in the inside of the cover. The internal space is a discharge space into which a high-pressure gas refrigerant discharged from the compressor flows. Each of the plurality of spaces faces a high-pressure chamber in the opening portion so as to be in direct communication with the high-pressure chamber.

Disclosed embodiments include an apparatus for reducing contamination or obstruction of a multi-directional flow filtration system. As one example, a scalper that is to be employed on a multi-directional flow filtration system comprises a body and a set of scalping walls forming a plurality of helical chambers, the set of scalping walls helically extending along at least a portion of an interior of the body in a longitudinal direction. In this way, the plurality of helical chambers may enable the multi-directional flow filtration system to passively scalp contaminants in a manner that improves overall operation of the multi-directional flow filtration system. Other embodiments may be described and/or claimed.

The present disclosure is related to surfaces having various topographical features and methods of making same. The disclosed features, created on various polycrystalline metallic substrates, may aid in effectively and rapidly reducing or eliminating detrimental effects of microbes. In some embodiments, the surface features may include channels and combinations of angular features such as ledges, ridges, and nodules, which may help adsorption of microbes to the surface, increase the surface chemical activity, and increase the effective surface area to support and/or accelerate the killing or deactivation of microbes. Some embodiments including reducing radii of curvature on channel ledges, intra-grain angular ridges, and angular nodules to accelerate disruption of microbial outer membranes by charge concentration and charge transfer. Also described are methods of producing the disclosed topographical surface features at low cost on various polycrystalline solid metal surfaces, for example cast, forged, rolled, drawn, wrought, deposited or coated.

A filtration assembly includes a housing. The housing includes a first housing for fluid and a second housing opening for fluid. A containment cover is removably coupled to the housing. The containment cover defines a cover opening, a cover surface, and a flow passage. The cover opening is in fluid communication with the housing. The cover surface is substantially continuous around a circumference of the containment cover. The cover surface includes an open portion in fluid communication with the second housing opening. The flow passage is formed by a first passage surface and a second passage surface. The flow passage includes a first end in fluid communication with the cover opening. A second end is in fluid communication with the second housing opening through the open portion of the cover surface. The flow passage extends radially outward from the cover opening.

The formation of sterilization tubes by plates with parts that match in whole or in part, that when assembled together form ducts, passages, channels, or tubes in a mass or block of heat resistant material. The size of the block may be reduced by forming the ducts as curved passages or tubes that will keep or increase the length of the tube while keeping the same or more exposure time while the gas is passing through. If the length of the curved duct is the same as a straight tube would have been, the overall size of the assembly may be reduced from what it otherwise would have been. If the curved length is made longer while the size of the assembly is kept the same, the exposure time is increased for a more effective sterilization.

A separator tank and a gas compressor having a separator tank are provided. The separator tank includes a tank body defining an inner volume, a tank inlet pipe providing fluid communication with the inner volume of the tank body, wherein the tank inlet pipe tangentially penetrates the tank body and is oriented to direct fluid entering the tank body in a spiral fluid flow pathway, and a sump tube positioned to collect fluid flowing within the tank body, the sump tube comprising a vertically oriented opening oriented to align and capture fluid flowing along the spiral fluid flow pathway.

A filter element including a filter media, an end cap, and a baffle. The filter media is configured to be secured within a housing. The housing includes an inlet configured to accept a fluid for filtering and the filter media including a circumferential outer surface. The end cap is positioned at and coupled to one end of the filter media. The baffle is positioned relative to the filter media at a position such that, when the filter element is correctly installed within the housing, the baffle is proximate the inlet of the housing. The baffle extends around only a portion of the circumferential outer surface of the filter media in a radial direction.

The present teachings provide for a housing for a panel filter, the housing including a main body, a plurality of first vanes, and a plurality of second vanes. The main body can define a chamber and a central aperture. The central aperture can extend through the main body and can be in fluid communication with the chamber. The plurality of first vanes can be disposed within the chamber and circumferentially spaced about the central aperture. Each first vane can extend radially outward from the central aperture a first distance. The plurality of second vanes can be disposed within the chamber and can be circumferentially spaced about the central aperture. Each second vane can extend radially outward from the central aperture a second distance that is less than the first distance.
