A sampling container assembly includes a sample receiving residue tube, a residue tube cap, inner and outer pipes, a container cap, a fixture block, and a supply conduit. The residue tube cap is assembled with the residue tube and defines inlet and outlet ports. The inner pipe has a lower end sealingly mounted to the fixture block and surrounding the residue tube to define an inner cavity for receiving a heat transfer fluid. The outer pipe has a lower end sealingly mounted to the fixture block and surrounding the inner pipe to define an outer annulus, with the container cap sealingly assembled with an upper end of the outer pipe. The supply conduit extends through the fixture block and the outer annulus and is connected with the inlet port of the residue tube cap for providing a sample fluid to the residue tube. The fixture block defines a passage extending to the outer annulus for supplying a chilling fluid to the outer annulus for chilling the heat transfer fluid in the inner cavity.

Interaction of adsorbing chemicals with a downhole tool presents inaccuracies in the adsorbing chemical measurement and analysis. The principles of the present disclosure provide a method and system of sampling fluids including an adsorbing chemical in a subterranean reservoir. One method may include modeling an interaction between the adsorbing chemical and a downhole tool, applying the model to a measurement of the adsorbing chemical, and adjusting the measurement in response to applying the model.

A sampling system for taking fuel samples from an external fuel tank includes a mobile platform, a sample tank carried by the mobile platform, and a supply line connected to the sample tank and configured to conduct the fuel from the external fuel tank into the sample tank. A mixing device is disposed in the sample tank and configured to mix fuel in the sample tank. A discharge line connected to the sample tank and configured to discharge the fuel from the sample tank. A sampling device is configured for removing a partial quantity of the fuel from the sample tank. A method for operating the sampling system is also described.

A fluid flow control and debris intercepting apparatus for controlling the flow of fluid and the introduction of debris into the entrance of a conventional curbside storm drain of the character having spaced apart side walls that define a fluid flow channel through which fluid flows. Additionally, the apparatus senses the nature and extent of contaminants contained within the fluid.

An apparatus for the collection of multiple samples of a fluid stream. The apparatus includes a plurality fluid collection containers arranged to receive separate portions of the fluid stream in a temporal sequence and a sealing mechanism provided on each fluid collection container configured to close the fluid collection containers when filled by a portion of the fluid stream and to cause the fluid stream to flow to the next fluid collection container in the sequence. The fluid collection containers separately collect at least a beginning portion of the fluid stream, a mid-portion of the fluid stream and an end-portion of the fluid stream. Each of the fluid collection containers may be detachably connected to tubing held in a housing having a sloped upper surface for receiving the fluid stream and an inlet for directing the fluid stream to the tubing. The housing may be a fluid collection cup.

A fluid sampling unit includes a housing and a shutoff valve adapted to selectively permit and restrict fluid flow to a fluid line disposed within an internal cavity of the housing. An electrically-actuated valve is disposed within the housing downstream from, and in fluid communication with, the shutoff valve. A first metallic line including copper is disposed within the housing in fluid communication with and between the shutoff valve and the electrically-actuated valve. A second metallic line including lead is disposed within the housing in fluid communication with and between the shutoff valve and the electrically-actuated valve. A control unit includes a controller adapted to selectively actuate the electrically-actuated valve.

Process inserts, assemblies, and related methods for use in monitoring high velocity fluids or supporting instruments that monitor and manage high velocity fluids are disclosed. Exemplary inserts include a head having a cavity for receiving an instrument, a shank, and an integral flange. The shank includes an elongated body having a first end disposed proximate to the head, a free end opposite the first end, and a threaded portion spaced apart from the first and free ends. Exemplary process insert assemblies include a process insert having a shank and a threaded support disposed around the shank. Methods of making and using process inserts are also disclosed. For example, a method of installing a process insert on a container includes inserting the free end of the process insert in the interior volume of a container containing a high velocity fluid.

[Solving Means] A sample liquid-sending apparatus includes a placement portion, a suction mechanism, and a vibrator. A sample container is placed in the placement portion, the sample container containing a suspension of a sample. The suction mechanism includes a nozzle configured to be inserted into the sample container placed in the placement portion, and suctions the sample through the nozzle. The vibrator vibrates the nozzle.
