An apparatus, for automated sampling from vessels that may be under a high pressure, is achieved by a specific construction with multiple multiport valves. A method of automated sampling can be used with the apparatus.

Provided is a concentration measuring apparatus, which measures a concentration of a fluid under a high-pressure environment, such as an environment in which a supercritical fluid is provided. The concentration measuring apparatus includes: a concentration meter for measuring a concentration of a first fluid contained in a fluid in the measurement line; a sampling line for transferring a process fluid of a processing space in which a substrate is treated in a high-pressure environment to the measurement line; a control valve for opening and closing the sampling line; a fluid pressure regulator installed downstream the control valve in the sampling line and configured to adjust the passing fluid to a set pressure; and a decompression tank installed between the sampling line and the measurement line.

The invention relates to a fluid sampling device comprising a sample chamber (01) including a lower piston (05), an upper piston (02) and an intermediate piston (28). Intermediate piston (28) is moved so as to guarantee a substantially constant volume for chamber (01) when closing the chamber.

A sampling module of a fluid processing apparatus includes at least one multi-configuration device connected to a filtration module. The invention relates to an area of non-disruptive sampling from any flow stream including the ones containing solids. The fluid processing apparatus remains in fluid communication with a sample processing module in all configurations of the sampling module and the parameters deemed critical for a chemical process remain unaffected during the sampling event. The entire event is controlled from a computer and the results are collected to make decisions on analytical and process controls.

A system for analysis of vent gas of a urea plant, comprising: a Raman spectroscope; a sampling conduit that connects the spectroscope to a main pipe of the urea plant configured to convey a sample stream to be analysed to the spectroscope; and a temperature-adjusting device, operated by a temperature controller and acting on at least one thermal treatment portion of the conduit configured to adjust the temperature of the sample stream circulating in the conduit.

An integrated sampling probe, valve and vaporiser (16) for a liquefied natural gas container is provided which comprises a vaporiser body (24) having a vaporisation chamber (66), a fluid inlet (40) in communication with the vaporisation chamber (66), a fluid outlet (58), and a vaporised-fluid flow path extending from the vaporisation chamber (66) to the fluid outlet (58). The fluid inlet (40) is formed as a critical orifice dimensioned to enable vaporisation of fluid passing into the vaporisation chamber (66), and there is a valve member (63) which is drivable to open and close the critical orifice, along with a heating assembly (50) for heating the valve member (63) to enable vaporisation of fluid passing through the critical orifice and into the vaporisation chamber (66). A sampling probe body (18) is also provided extending from the vaporiser body (24), the sampling probe body (18) having a sampling bore (36) which is in fluid communication with the fluid inlet (40).

A modular sample conditioning system formed for in-situ sampling installation, referenced herein as “source mounted”. The preferred embodiment of the present invention relates to a docking platform or substrate configured to receive multiple, diverse sampling components in various flow configurations, coupled with a unique housing/enclosure formed to engage the docking platform so as to further strengthen and stabilize the mount, the enclosure also formed to engage one or more of the mounted sampling components, so as to provide access outside of the enclosure for visibility and/or manual access of same, providing an easily installed and maintained, user-accessible, on-site modular sampling conditioning/monitoring system.

A system for on-stream sampling of pressurized process gas such as natural gas or the like, including pressurized process gas having liquid entrained therein, or otherwise referenced as “wet”. The preferred embodiment of the present invention contemplates a system for obtaining an accurate sample of process gas, as well as providing an apparatus for obtaining same.

A device for sampling a fluid, includes a sampling chamber including a first piston driven by the fluid, and an additional device configured to increase the volume of the sampling chamber. The sampling chamber serves as both a sampler and also as a container for the sampled fluid and it can also be used as a cell for the analysis of the fluid.

A lid mounted water sampling system adapted to be fluidly coupled to a water line for obtaining water quality parameters corresponding to a sample of pressurized water from the water line and transmitting information associated with said water quality parameters to a remote location, the system comprising: a pit lid adapted to be positioned to cover a pit box such that during use an outer surface of the pit lid is substantially at ground level and adapted to be positioned upon the pit box located underground; the pit lid further comprising an in-use underside portion coupled to a water sampling apparatus, the water sampling apparatus adapted to be positioned in an internal volume defined by the pit box, the water sampling apparatus being fluidly coupled to the water line for obtaining water quality parameters corresponding to a sample of the pressurized water from the water line; and a data transmitter positioned adjacent said pit lid in electronic communication with the water sampling apparatus for transmitting the water quality parameters to the remote location.
