A free-standing riser system connects a subsea source to a surface structure. The system includes a concentric free-standing riser comprising inner and outer risers defining an annulus there between. A lower end of the riser is fluidly coupled to the subsea source through a lower riser assembly (LRA) and one or more subsea flexible conduits. An upper end of the riser is connected to a buoyancy assembly and the surface structure through an upper riser assembly (URA) and one or more upper flexible conduits, the riser also mechanically connected to a buoyancy assembly that applies upward tension to the riser. The riser may be insulated for flow assurance, either by a flow assurance fluid in the annulus, insulation of the outside of the outer riser, or both. The system may include a hydrate inhibition system and/or a subsea dispersant system. The surface structure may be dynamically positioned.

An apparatus and method for preventing particulate matter and residue build-up within a vacuum exhaust line of a semiconductor-processing device. The apparatus includes a vessel chamber having an inlet, an outlet and a fluid conduit between the two that fluidly couples the outlet with the inlet. The fluid conduit includes first and second collection sections. The first collection section includes a first plurality of electrodes aligned parallel to a first plane and the second collection section includes a second plurality of electrodes aligned parallel to a second plane that is substantially perpendicular to the first plane. The electrodes are connected to a voltage differential to form an electrostatic particle collector that traps electrically charged particles and particulate matter flowing through the fluid conduit. Particles are collected on the electrodes within the fluid conduit during substrate processing operations such as CVD deposition steps. Then, during a chamber clean operation, unreacted etchant gases used to clean the substrate processing chamber are exhausted through the foreline and into the apparatus of the present invention where they react with the collected particles and powder to convert the solid material into gaseous matter that can be pumped through the foreline without damaging the vacuum pump or other processing equipment.

A seal, a vent for a filter housing and a system for using them. The seal is designed a first outer seal having a closed outer periphery that divides and isolates a first inner area from the outside environment and a second inner seal formed along a portion of the inner surface of the first outer seal and forming a second inner area within the first inner area and which is isolated from both the first inner area and the outside environment. The seal is incorporated into a vent for a filter housing having opening is contained within a vent area and the opening is offset from the center of the vent area. The opening establishes a fluid pathway from the interior to the exterior of the filter device. The inner seal surrounds the vent opening. The outer seal also surrounds the vent opening at one of its ends and surrounds the entire periphery of the vent area so as to isolate the vent area from the area outside of the vent area. A vent cap is secured at its outer periphery to the outer periphery of the vent area. The cap has an exhaust port which when in alignment with the vent allows fluid to flow out of the housing interior. The exhaust port is offset from the center of the cap and is designed to align with the offset opening of the vent. The cap is either moved in a linear or rotational motion and the vent opening and the cap opening are always contained within the area defined by the outer seal so as to form a sanitary seal. Also disclosed in a sanitary recovery system utilizing the seal and vent of the present invention.

摘要:
A sterile to sterile connection device comprising a connector and one or more coupling devices. The connector has body portion which has two openings sealed from the environment so as to form a sterile environment within the connector. At least one of the openings being sealed from the environment by a sterile barrier plug. The connector also has a port capable movement within the body of the connector to at least an open and a closed position. The coupling device is formed of a body having two openings and a stem having a bore through at least a portion of the stem. The stem is contained within the body and capable of moving at least linearly through the body between a first and second stem position. One of the openings of the stem is sealed from the environment by a sterile barrier plug and the other is sealed to a presterilized component. The coupling device opening containing the sterile barrier plug is attached to either the inlet or outlet of the connector.
