A chiller water sampling device includes a pair of flow meters and a proportional valve to provide a constant flow rate of sample water containing peroxyacetic acid from a chiller to a mixing tank. Acid can be added to reduce the pH of sample water in the mixing tank to bring the pH within the operating range of a peroxyacetic acid sensor. The sensed level of peroxyacetic acid can be used to control further addition of peroxyacetic acid to the chiller.

Provided are a compact mixing system capable of reducing a use amount of a mixing agent and reducing a volume of a utility that supplies the mixing agent, and a measurement system using the mixing system. The mixing system includes: a mixing agent discharge nozzle through which a mixing agent to be mixed with a sample is to be discharged; and a movable mechanism configured to adjust a gap between the mixing agent discharge nozzle and a sample collection port that opens to an inside of a sample tube through which the sample is to flow so as to collect the sample.

A multiple port connecting assembly includes a connector body and a fluid isolation adapter. The connector body includes a first fluid passage extending from an adapter port to a first connector port, a second fluid passage extending from the adapter port to a second connector port, a first seat portion disposed between the first fluid passage and the second fluid passage, and a second seat portion disposed between the second fluid passage and an open end portion of the adapter port. The fluid isolation adapter is removably assembled with the adapter port and includes an adapter body defining a first end passage that connects with the first fluid passage, a second end passage that connects with the second fluid passage, a first seal portion sealing against the first seat portion, and a second seal portion sealing against the second seat portion.

A method and system for detecting foreign particles in a liquid, the method and system include transmitting transmitted pulses of radiation, by a transmitter, towards a liquid conduit that is filled with liquid; wherein the transmitted pulses comprises pulses that differ from each by being associated with absorbance frequencies of different foreign particles; receiving, by a receiver, received pulses that propagated through liquid as a result of the transmission of the multiple transmitted pulses; comparing between the transmitted pulses and the received pulses to provide a comparison result; and determining a liquid contamination based on the comparison result.

A continuous production system continuously produces a product from a raw material powder. The system includes a first processor that performs a first process on the raw material powder, a second processor that performs a second process on the powder on which the first process has been performed by the first processor, and a test chamber through which the powder being sent from the first processor to the second processor passes. A cleaner blows gas from an inlet side opening formed in the inner face of a channel connected to the test chamber from the first processor on the downstream side of an inlet side gate valve for opening and closing the channel toward a direction to form a swirling flow along the inner face of the channel.

Methods and systems are provided for treating the tail gas stream of a sulfur recovery plant. The methods including generating a tail gas stream from a sulfur recovery plant, treating the tail gas stream with a hydrogen sulfide absorption unit and a hydrogen selective membrane unit, generating a stream low in hydrogen sulfide and a stream rich in hydrogen. The hydrogen sulfide rich stream is recycled to the sulfur recovery unit. The hydrogen selective membrane unit includes a glassy polymer membrane selective for hydrogen over hydrogen sulfide and carbon dioxide.

A tubular scoop that may be utilized with various assemblies for sampling fluid in a pipeline. The scoop includes a bend with a bend radius that may be from two to four times the diameter of the scoop. The scoop defines a scoop face that is generally parallel to an axis of the tubular of the scoop. The scoop is mountable with a threaded connection that seals around the tubular. An additional seal may comprise a compression nut that allows orientation of the scoop within the pipeline whereupon the scoop orientation is fixed by tightening the compression nut. In one embodiment, the scoop is a single outer tubular with internal bi-directional flow.

A cryogenic liquid sampling system including a chamber having affixed therein a sample pump to proportionally pull a cryogenic liquid sample from an external source to a constant pressure piston accumulator and an enclosure. The enclosure includes a supply port to receive an input stream of a gas, an input port connected to the chamber via a vacuum line, a sample pump port connected to the chamber via a pump line and configured to feed therethrough gas received at the supply port to the sample pump, a vacuum device connected to the input port and configured to generate a vacuum within the chamber by pulling air from the vacuum line, and processing circuitry to control the vacuum device and the sample pump to perform transfer of a cryogenic liquid sample from the external source to an external device.

The present invention relates to a test system and method for a biomass-based blended fuel. The system comprises a feeding device, a mixing tank, a light-sensing device, and a control device; the feeding device comprises at least two fuel bottles; the fuel bottle is connected to the mixing tank by means of an oil pipe; the correspondingly connected oil pipe of each fuel bottle is provided with a flow valve; the light-sensing device comprises a laser disposed above the mixing tank, a light-reflecting mechanism disposed at the bottom in the mixing tank, and a light-sensing mechanism disposed at one side of the light reflecting mechanism; the output end of the light-sensing mechanism is signaled with the input end of the control device; the input end of the laser and the input end of the flow valve is separately signaled with the output end of the control device. According to the present invention, the structure is simple, and an ECU control device is used to carry out numerical control on each mechanism, and the miscibility of a blended fuel of a changed relationship between the miscibility of the blended fuel and ambient temperature can be rapidly measured by using the principle that the blended fuel has different refractive indexes in a miscible state and in a stratified state.
