摘要： A sampling system (10) samples particulate material in a high-temperature, high-pressure gas stream (20) flowing in process pipe (22). A sampling device (12) comprising an alumina lined activated bauxite alkali vapor collector (16) and a threadless sacrificial connector containing cyclone separator (14) is inserted into stream (20) via a pipe flange (24) connected to block-and-bleed valves (52, 54). (In alternative embodiments instead of a cyclone separator (14) a cascade impactor (240) with integrally spaced and aligned jet plates (282) having collection substrates (284) may be used). Support structure (30) supports a stepper motor (32) driving screw actuator (34) carrying draw yode (38) is driven along linear bearing rail (40) by engagement with screw actuator (34). Draw yoke (38) engages sampling device carrying probe (42) so as to mobe in axial direction (A). Probe rotator (44) mounted to carriage (39) can be controlled or monitored by local controller/monitor (46) or remote one (48) which can also monitor and control axial movement production.

摘要： A sampling cup for microbiological suspension particles in an atmosphere and portable sampling device provided with one such cup. The sampling cup for microbiological particles in a suspension in an atmosphere comprises a rotary cup body provided with a bottom (30) and a peripheral wall (32) which is generally cylindrical, extending from said bottom and defining with said bottom a volume filled with a trapping medium for the suspension particles. The body of the cup also comprises a crown (34) partially closing the outer section of the peripheral wall of the body and defining a passage (36) for the particles. The crown is provided with channels (38) extending in an externally outer radial manner in the direction of the periphery of the body and adapted in such a way that it produces an air flow towards the receiving medium filling the body via said passage when the body is rotated in a housing.

摘要： Improved apparatus for collecting particles from air comprises a cyclone (13) having air inlet (14) and outlet (15) means, means maintaining an airflow there through and means (28) delivering a collecting fluid from a reservoir (26) to particles separated from the air flow in the cyclone (13), in which the air inlet means (14) is associated with means for heating (30) the incoming air. The apparatus, which is optionally provided with enclosure means for trapping heat, prevents freezing of the collecting fluid at temperatures near to and even below 0 grade C.

摘要： With reference to Figure 1, and air sampler 1 for use in analysing biological or other analytes, comprises an airflow chamber 2 having an air inlet 3 and an air outlet 4. An extract from 5, draws ambient air in through the inlet 3, and then through the chamber 2, to discharge it back to atmosphere by way of an outlet 6. The airflow chamber 2 houses a cyclone air/liquid separator 7 through which the inflowing air is caused to pass. An injector 8 introduces liquid into air flowing through the air inlet 3. The cyclone separator 7 extracts this liquid and any entrained particles therein and discharges it from the airflow chamber 2, initially by way of a duct 9, where it is then conveyed to a collection vessel 12, by way of a three channel peristaltic pump 13, and a duct 14. The collection vessel 12 is housed within a Peltier-cooled holder 15 to maintain the contents of the vessel 12 within the 2 °C - 8 °C range which is desirable for maintaining the integrity of biological analytes such as bacteria or proteins. Analyses such as PCR, culture on agar plates or immunoassays may be performed on the collected samples. The holder 15 also houses sample bottles 16, 17, 18 and 19.

摘要： A method for continuous monitoring the presence of entrained catalyst in a regenerator flue gas stream of a fluidized catalytic cracking unit is provided. The method comprises the following steps: (a) passing the regenerator gas stream through a separation system to remove a portion of the catalyst fines and to create a cleaner regenerator gas stream; (b) collecting a sample portion of the cleaner regenerator gas stream and directing the sample portion of the cleaner regenerator gas stream through an inertial separating device to separate entrained catalyst from the sample portion of the cleaner regenerator gas stream; (c) collecting any separated catalyst from the inertial separating device; and (d) monitoring the efficiency of the separation system by analyzing at least the amount of the collected separated catalyst or the particle size of the collected separated catalyst. An apparatus for measuring the amount of potentially erosive catalyst fines in a regenerator flue gas stream in a fluidized catalytic cracking unit is also provided. The apparatus comprises a sampling probe for collecting a sample portion of the regenerator flue gas from a line through which the regenerator flue gas stream flows, and an inertial separating device located downstream of the sampling probe and in fluid communication therewith, for removing any entrained catalyst fines from the sample portion of the regenerator flue gas.
