摘要:
A system for separating hydrocarbons from water, the system including an inlet for receiving a fluid, the fluid including a water phase and a hydrocarbon phase, and a separation tank having a first partition and a second partition, wherein the first partition is configured to receive the fluid from the inlet. Furthermore, the system includes a first outlet configured to receive the water phase from the first partition, a second outlet configured to receive the hydrocarbon phase from the second partition, and a support structure configured to receive the water phase from the first outlet and the hydrocarbon phase from the second outlet. Also, a method of separating a fluid into a water phase and a hydrocarbon phase, the method including injecting the fluid containing the water phase and the hydrocarbon phase into a separation tank. The method further includes separating the water phase from the hydrocarbon phase, wherein the separating includes transmitting the fluid through a plurality of baffles, collecting the water phase, and collecting the hydrocarbon phase.

The invention relates to a fluid filter, in particular for filtering water, comprising a plurality of inlet channels (2), a plurality of outlet channels (3) and filter walls (4) separating the inlet channels (2) from the outlet channels (3), wherein the inlet channels (2) are arranged parallel to the outlet channels (3), wherein the filter walls (4) have a plurality of pores through which the inlet channels (2) are connected to the outlet channels (3), wherein a cross-section area of all inlet channels (2) is larger than a cross-section area of all outlet channels (3), and a value of diameters of the pores of the filter walls (4) calculated by means of quicksilver porosimetry is a median d 50 , lying between 0.01 to 0.5 μm, preferably between 0.03 to 0.2 μm, further preferably between 0.05 to 1.5 μm and most preferably equaling between 0.05 and 0.1 μm.
摘要:
An acidizing composition useful for treating a subterranean hydrocarbon producing formation and removing scale from oilfield equipment, the composition including: an acid; water; and an effective amount of a corrosion inhibitor composition including: at least one mercapto-compound; and at least one alkoxylated acetylenic alcohol. Also disclosed are methods for removing scale from metal surfaces and for treating a subterranean hydrocarbon producing formation with such an acidizing composition whereby the corrosive effects of the acidizing composition on metal surfaces in contact therewith are reduced.

摘要:
Methods and systems for treating a waste stream (202) in a waste treatment system (204) involve performing a unit process (206) by contacting the waste stream (202) with oxyhydrogen-rich gas (214) generated on-site by an oxyhydrogen gas generator (207). The gas generator (207) preferably involves applying a pulsed electrical signal to a series of closely-spaced electrodes that are submerged in the waste stream (202) to dissociate a water component of the waste stream (202), thereby producing oxyhydrogen-rich gas (214, 220). Operation of the gas generator (207) in the waste stream (202) may accomplish one or more unit processes (206) for waste treatment, such as conditioning, stabilization, thickening, and dewatering, among others. At least a portion of the oxyhydrogen-rich gas (220) can be conveyed for a second use (222) in the waste treatment system, such as a source of combustible fuel for incineration or power generation, for example.
