Abstract: The present invention is drawn to a method for measuring crude oil contained in a gas flowing in a gas line which incorporates the steps of obtaining a sample of gas from the gas line, passing the sample of gas through a selective crude oil trap, measuring the volume of the sample of gas, and measuring the volume of trapped crude oil. The selective crude oil trap includes a cooled coil and at least one cylinder filled with a fluid which is non-soluble with oil and which is preferably refrigerated. The selective crude oil trap may alternatively include a filter device which has a cylinder filled with a polymerized porous medium bound with a phenolic resin. The apparatus for carrying out the method has inlet and outlet connectors which allow the apparatus to be releasably connected to a gas flow line to obtain a sample of gas and to be disconnected and physically transported to a remote facility for completion of the testing.

Abstract: Disclosed is a sampling method and apparatus in which sampling is accompanied by the steps of inducing a sample to flow into an outer chamber and excluding the sample from an inner chamber by inducing a first pressure zone in the inner chamber such that a substantially discrete interface between the first pressure zone and sample is formed at an orifice between the outer chamber and inner chamber; sufficiently reducing the first pressure zone in the inner chamber to induce the sample to flow through the orifice between the outer chamber and inner chamber and into the inner chamber such that first pressure zone-sample interface is substantially undisturbed when it moves through the orifice between the outer chamber and inner chamber; inducing the sample to flow from the inner chamber into an inner tube having an orifice within the inner chamber which forms a pathway to a detector such that the first pressure zone-sample interface remains substantially undisturbed; inducing a second pressure zone in the inner chamber such that a substantially discrete interface between the sample and second pressure zone is formed at the inner tube orifice; and inducing the sample to move along the pathway such that the first pressure zone-sample interface and second pressure zone-sample interface are substantially maintained.

Abstract: An air delievery monitoring system covers an aperture of an air duct with an insert having a bore. A filter element in communication with the inside of that air duct through that bore is made accessible from outside of that duct. Air escapes from the duct through the bore in the insert to the filter element which traps contaminants in such air for subsequent laboratory analysis. The filter element is preferably encapsulated in an apertured filter element housing which is mounted in the insert in communication with its bore. After removal of that housing from the insert, the contaminated filter element can be transported or sent to the laboratory for the performance of several analyses thereon.

Abstract: An exhaust adapter for exhaust gas measurements which can be attached to the tail pipe of an exhaust unit and to which can be connected a hose leading to the analyzing measuring system. Two pipes, one telescoped into the other, are provided for attachment to a tail pipe. An elastic sealing ring is arranged between the end edge of the inner pipe and a drawn-in collar of the outer pipe. The outer pipe may be restrained with respect to the inner pipe for a gastight seal on the tail pipe by the measure of a compression of the sealing ring.

Abstract: This invention is directed to a high pressure drop cascade impactor wherein the particles do not bounce from the collection plate; to a method for designing said impactor; a method for calculating and determining the particle size distribution of an aerosol wherein the particle size may have a Stokes (aerodynamic) diameter as small as 10 nanometers; and to a method of manufacturing such an impactor.The impactor that is the subject of this invention is different from and superior to previously described impactors in the following principal respects:1. The particles exhibit substantially no reentrainment, or bounce, from the collection surfaces. This property is achieved by (a) limiting the exit jet stream velocities such that the herein defined "bounce parameter", .beta., is never exceeded, and (b) increasing the thickness of the jet plates to elongate the jet passageways in order to reduce the jet velocities so that bounce will not occur.2. The impactor described herein eliminates turbulence near the entrances to the jet holes by rounding the edges of the jet holes. This is accomplished on the small holes by means of electropolishing.3. The impactor described herein is capable of capturing particles as small as 40 nanometers Stokes (aerodynamic) diameter. By contract, previously described impactors could capture particles only as small as 300 nanometers Stokes diameter.
