Abstract: This disclosure provides a method for treating natural gas comprising causing at least some of a sour natural gas stream comprising hydrocarbon gas and hydrogen sulfide to contact an amine or pass through a separation system. A sweet natural gas stream comprising hydrocarbon gas and a waste gas stream comprising hydrogen sulfide are formed by contacting the sour natural gas with an amine or by passing it though a separation device. At least some of the hydrogen sulfide in the waste gas stream is oxidized, forming an exhaust gas stream comprising sulfur dioxide, which is then contacted with water or reactant and water solution or slurry to destroy or convert SO2 into a less environmentally harmful compound.

Abstract: Improved systems and methods for cleaning a filter are described, including apparatuses that include a built-in mechanism for cleaning a filter screen. The system can include a brush mounted in contact with a filter screen, adapted so that the brush can be moved to clean the filter screen. In some versions, the brush rotates with an axis of rotation perpendicular to a plane defined by a substantially planar filter screen. In other versions, the brush is adapted to be moved by a gravitational force along a surface of a filter screen upon removal of a pump housing from a pump well. In still other versions, a substantially cylindrical brush is mounted nested with a substantially semi-cylindrical filter screen, and the brush can be rotated while in contact with the filter screen and with an axis of rotation aligned with a longitudinal axis of the filter screen.

Abstract: A double action seating unit to be mounted to a nose of a platform is described. The double action seating unit includes a seat assembly, a back assembly and at least two stanchion. Each stanchion has a front bracket, a rear bracket, a stanchion tube and two pivot straps. The front bracket attaches the seat portion to the stanchion, the rear bracket attaches the stanchion to the nose of the platform and the stanchion tube attaches the back assembly to the stanchion. Each pivot strap connects an associated stanchion tube, the rear bracket and the front bracket. The double action seating unit can move between a use configuration and a storage configuration. The two pivot straps cause the seat assembly and the back assembly to simultaneously rotate when the double action seating unit moves between the use configuration and the storage configuration.

Abstract: Porous implantable devices for housing one or more therapeutic agents are disclosed herein. The implantable devices include a porous outer wall defining an interior void. The interior void houses a carrier material carrying a first therapeutic agent. The implantable devices are made by patterning at least a portion of a polymerizable substrate into a polymerized three-dimensional porous outer wall surrounding an interior void. This can be achieved by two-photon polymerization techniques. A first therapeutic agent is then added to the interior void, which is then sealed. Methods of treating diseases using the implantable devices are disclosed herein. The methods include implanting the implantable device at a target area and locally releasing a therapeutically effective dosage of a first therapeutic agent from the interior void. The implantable devices can also be used in methods of screening potentially therapeutic agents for desired biological responses.
