摘要： A cleaning system includes an explosive subsystem including: a plurality of detonation cords extending along a direction different from a vertical direction; and a locating assembly locating the plurality of detonation cords relative to each other. The locating assembly spaces each of the detonation cords apart from a system to be cleaned. The cleaning system includes a pressurized air blower assembly adjacent a portion of the system to be cleaned, the pressurized air blower assembly being configured to direct pressurized air towards the portion of the system to be cleaned after the detonation cords have been exploded.

摘要： The steam generating unit of dual circuit reactor with blowdown and drain system is implemented in the close loop, without any conventional blowdown expansion tanks and is designed for maximum pressure of the steam generator (SG) working medium. The SG blowdown water is combined into a single line, cooled down in the regenerative heat exchanger, then in the blowdown aftercooler and drain cooling line and taken out of the tight shell. Out of the tight shell, the SG blowdown water is supplied for treatment to the SG blowdown water treatment system designed for maximum pressure of the steam generator (SG) working medium. After treatment, the water returns to the tight shell and, via the regenerative heat exchanger, to the feed pipelines of each SG. The invention provides increased SG blowdown that leads to the accelerated chemical condition normalization even with considerable deviations.

摘要： The invention relates to a method for evaluation of fouling of passages of a spacer plate (10) of a tubular heat exchanger (11), wherein first, second and third pressure sensors (31, 32, 33) are arranged, the method comprising steps of: (a) during a transient operation phase of the heat exchanger determination of a value over time of Wide Range Level NGL, from the measurements of the first and third pressure sensors (31, 33), and of a value over time of Narrow Range Level NGE, from the measurements of the second and third pressure sensors (31, 33); (b) determination of a value over time of Steam Range Level deviation ΔNGV, corresponding to the NGL from which a component representative of a variation of free water surface in the heat exchanger has been filtered, from the values of NGL and NGE; (c) comparison of the determined value of ΔNGV with a set of reference profiles ΔNGVi for said transient operation phase of the heat exchanger, each reference profile ΔNGVi being associated with a level of fouling so as to identify a target reference profile ΔNGVopt among the reference profiles ΔNGVi for said transient operation phase of the heat exchanger, which is that closest to the determined value ΔNGV. (d) restored on an interface (3) of the level of fouling associated with the identified target reference profile ΔNGVopt.

摘要： A system for deriving 100% quality steam for steam assisted gravity drainage (SAGD) injection or other applications features a once through steam generator (OTSG), a steam-water separator connected downstream of the OTSG's radiant tubes to separate steam and water from a two-phase flow received therefrom, superheater tubes installed in the convection section and connected to a steam outlet of the steam-water separator in downstream relation thereto to receive and heat dried steam therefrom to a superheated state, and a desuperheater connected downstream of the superheater tubes to receive the superheated steam therefrom and use same to vaporize blowdown water from the steam-water separator, whereby the vaporized blowdown water and the superheated steam collectively form a superheated steam output for the intended application, typically after additional separation of solid particles therefrom for optimal steam quality.

摘要： A cleaning apparatus for cleaning a cooling tube array (15) of a heat exchanger has a nozzle carriage (16) movably held on a truss beam, and a plurality of cleaning nozzles (40) mounted to the nozzle carriage. A truss beam has two parallel C-channel rails (20) having back sides that face each other, a tube (22) arranged separate and distant from the C-channel rails and at a different height than the C-channel rails in a cross-sectional plane of the truss beam, and truss supports (24) connecting the rails and the tube; the nozzle carriage has rollers (48) that are arranged for travelling in the C-channel rails. A water intake (82) is coupled to the nozzle manifold (42) and to a hydraulic drive (80) having a mechanical power take-off member (96) that is operably coupled to the nozzle carriage (16) for moving the nozzle carriage.

摘要： A system of generating steam from an emulsion stream produced from a reservoir via thermal recovery has a heat exchanger for adjusting the emulsion to a first temperature; at least one separation device for separating water from the emulsion at the first temperature to obtain produced water; an optional produced water preheater, and a high pressure evaporator for receiving the produced water and generating steam using the produced water. The evaporator has a vapor drum; a heating element receiving the water stream, and in fluid communication with the vapor drum via a pressure letdown device; a heating source for imparting sensible heat to the water stream for generating steam. The evaporator also includes a recirculation pump for circulation of blowdown concentrate, and a bubble generator for generating bubbles and injecting generated bubbles into the heating element to enable self-removal of scales and other solid deposits in the evaporator.
