Abstract:
The present invention discloses systems, apparatuses, and associated methods for producing, separating, storing, and offloading hydrocarbons from a hydrocarbon producing well in a subsea environment, which may be a remote, arctic subsea environment. In particular, the systems include a large gravity-separation tank or tanks constructed at least partially from structural concrete to separate oil, water, gas, and/or particulates. The gravity- separation tank or tanks may be connected to one or more buoyancy cells in a large gravity- based structure (GBS), which may be built in a graving dock, towed to a remote location (e.g. arctic), ballasted to the seafloor and integrated into a subsea hydrocarbon production system. The system may further include an offloading system and a local power supply.
Abstract:
The invention presented is an apparatus specifically designed for the high rate anaerobic treatment of (waste)waters with relatively high concentrations of lipidic compounds, referred to as the Inverted Anaerobic Sludge Blanket (IASB) reactor. Contrary to conventional anaerobic reactors, it avoids the need of sludge with good settling properties and exploits the problem of sludge flotation due to long chain fatty acid (LCFA) or biogas adsorption onto the sludge and/or biogas encapsulation by the sludge. Furthermore, it provides an increased specific sludge surface area for better LCFA degradation. It is fed from the top and is equipped with a separation step at the bottom. Reactor contents are thoroughly mixed by the novel combined action of a gas lift loop and a liquid recycle over the reactor. The reactor can be operated in continuous and sequential mode. Although it is specifically designed for lipid degradation, its application is not limited to this.

Abstract:
A system and process are provided for recovering and/or cleaning residual or waste petroleum products such as sludge accumulated within a storage tank or upon process equipment surfaces, or from inorganic materials such as sand or clay, and the like. The system and process include a negatively charged aqueous-based dispersion fluid, which is contacted with the petroleum product under controlled relatively high pressure and high shear conditions for fluidizing hydrocarbon molecules and for preventing such molecules from adherence to process equipment surfaces, or contaminants such as sand or clay. Additional mechanical separation as by subjecting the mixed petroleum product and dispersion fluid slurry to sonic vibration may also be employed. The thus-fluidized slurry of petroleum products, dispersion fluid, and inorganic materials can be separated by conventional techniques, as by setting and/or flotation, for further individual processing and/or re-use.

The method comprises the steps of firstly removing metallic waste from conveyed waste; crushing the waste from which the metallic waste is firstly removed; secondly removing metallic waste from the crushed waste by using a difference in specific gravity; dehydrating the waste from which the metallic waste is removed; drying the dehydrated waste; pulverizing the dried waste; and compressing and shaping the pulverized waste, thus producing solid fuel.
Abstract:
A self priming pump system that includes a motor coupled to a centrifugal pump for driving the centrifugal pump. A separator having a reservoir is provided for storing a limited amount of pumped fluid in advance of the centrifugal pump. A vacuum source provides a vacuum suction to the reservoir to draw pumped fluid into the reservoir to prime the pump. To increase the reliability of the vacuum pump system, a deflector and/or extension maybe provided in the reservoir to help prevent pumped fluid from entering the vacuum pump input. Also, the configuration of a tank used to store liquid for the vacuum pump system may be configured to separate and collect sediments near a drain port, which then can be easily drained. For positive head pressures, one or more valves may be used to prevent pumped fluid from escaping the reservoir, if desired.

Abstract:
A separator for separating particles, especially amalgam particles, from effluent liquid obtained from the suction apparatus of a dental office, preferably driven by a common vacuum pump, includes a sedimentary deposit tank for sedimentation of solid particles in the effluent. A surge tank is provided for accommodating effluent overfill and providing its effluent output to the sedimentary deposit tank. A bypass conduit is connected in parallel with the separator and to a vacuum check valve in the vicinity of the separator inlet port for passing air into the separator when the suction apparatus is closed to ambient air, so that whenever the vacuum pump is operating, air is sucked into the separator either through the suction apparatus thence into the separator inlet port or via the vacuum check valve. The surge tank preferably has a liquid level sensor and associated warning device. An auxiliary filtration device may be connected downstream of the sedimentary deposit tank, and both of these units are preferably removably replaceable as modular units. Provision is made for optional auxiliary equipment to improve filtration and to accommodate a positive air pressure source. A full tank drying facility is optionally provided.
Abstract:
A method and apparatus are provided for detecting and controlling a level of a mud bed in a high compression gravity thickener (10). The thickener is fitted with upper and lower vibrating probes (12 and 24) which vibrate at a predetermined amplitude and frequency. When the mud bed reaches a level (30), the vibrating probe (12) is switched, thereby delivering an "on" signal via a control line (32) to turn on an underflow pump (22). In the event of the mud bed reaching a lower level (34), the vibrating probe (24) transmits an "off" signal via a control line (36), thereby turning the pump (22) off and allowing the mud level to increase. The control signals from the upper and lower vibrating probes (12) and (24) are thus used to adjust the throughflow of mud by adjusting the speed of the underflow pump (22) so as to control the level of the mud bed within the thickener.
