摘要:
An apparatus and method for simultaneously measuring water content profiles, surface/interfacial levels, thicknesses and tensions of multiphase dispersions, such as dispersions with water dispersed in produced oils, crude oils, various fuels, distillates, lubricants, paints and polymers, or reversed dispersions with these organic components dispersed in water. The apparatus with 1-16 channels, namely multi-channel scanning water analyzer (MCSWA) and/or tensiometer, comprising a motorized precision vertical stage with multiple capacitive sensors, a heating system with multiple heating cells for keeping the respective sample bottles, and a data acquisition system, where the capacitive sensors can be precisely controlled via a computer to dip into the samples at a preset scanning velocity and the capacitances of the sensors are continuously measured by the data acquisition system. The measured sensor capacitances are used to derive water content profiles, surface/interfacial levels, interfacial thicknesses and surface/interfacial tensions of the respective samples. The apparatus is a good tool for R&D scientists to select chemicals efficiently and can provide reliable data for engineering design and product quality assurance.
摘要:
A process and system for oil-contaminated soil remediation and oil recovery from oil-bearing media such as oil-contaminated soil, different types of oil-bearing sludge's from oil producers, upgraders and refineries, oil shale, oil sands, and coal oil shale, oil sands and coal includes (1) a portable or fixed twin thermal desorption unit with two rotating trundles in one stationary house, and (2) multiple co-combustion burners burning coal, scrap tires, used oils, sludge's containing high oil content, propane and natural gas to supply heat for the twin desorption unit, and (3) a suction fan to create a slightly vacuum environment, receive vapors and send them to (4) a cooling line with a heavy component condenser to condense heavy oils, a set of air cooling pipe to condense light oils and steam and a three-phase (gas/oil/water) separation tank to separate oil from water, and (5) a feeding line with a blender to break wet lumps and a crasher to break rocks presence in the raw material being processed.

摘要:
A handhold apparatus is provided for pushing in and pulling out an inspection probe to and from a tube of a heat exchanger for ultrasonic internal rotary inspection system (IRIS) and eddy current testing (ECT). The apparatus is light weight (less than 5 lb) and is wireless controlled for ease of use and portability. The probe can be moved forward, stop and backward via wireless control. There are both fine and coarse adjustment for the probe's moving speed as well as position limit setting and resetting as the probe's soft start point and soft end point for inspecting the first tube, subsequent inspections of other similar tubes in a bundle can be carried out quickly using the settings.
摘要:
A heat pipe based passive residual heat removal system for a spent fuel pool (3). Partitions (6) are arranged around an inside of the spent fuel pool. Evaporation-end heat pipes (4) are arranged between the outside of the partitions and an inner wail of the pool. The evaporation-end heat pipes have outlets that extend beyond the pool and are connected to an Inlet of an ascending pipe (10), and have inlets connected to an outlet of a descending pipe (5). Condensation-end heat pipes (7) have inlets connected to an outlet of the ascending pipe, and have outlets connected to an inlet of the descending pipe. The heat pipes cool the spent fuel pool. A heat exchange by phase change of working medium in the heat pipe leads to heat exchange of low temperature difference and high efficiency, relying on density difference for natural circulation drive.
