摘要:
A system and method for substantially coincidental sample takeoff flow rate verification which detects unstable flow conditions in a pipeline, terminates fluid sample analysis during flow instability, and resumes sample takeoff when a steady flow state is re-established.

An anti-fouling, radiation emitter isolation assembly includes an adapter element mounted to a fixed port at the top of a leachate tank. A radiation emitter/detector is further mounted to the adapter element for transmitting radiation through the fixed port to determine a fluid level. The adapter element incorporates an isolation valve that when opened provides an unobstructed window through the fixed port for the transmitted radiation and when closed isolates said radiation emitter/detector from the fixed port. In particular, selectively isolating the radiation emitter/detector from the interior of the tank permits removal of the radiation emitter/detector from the adapter element without requiring a shutdown of leachate tank system operations.
摘要:
A post-probe upstream metering pump for insuring phase change completion of a multi-phase fluid such as Natural Gas Liquid (NGL) in a sample conditioning system having a pipeline sample take-off probe for fluid extraction, a sample conditioning unit for conditioning the extracted fluid to a select range of temperature and pressure for analysis of the fluid sample by an associated analyzer without dew point dropout or phase separation, and a metering pump disposed in-line between the sample take-off probe and the sample conditioning unit to pressurize the fluid sample to condense into a substantially fully liquid phase and to reduce lag time between extraction and fluid sample conditioning.
摘要:
Provided herein is a solar powered system for a gas sampling and analysis for placement and operation remote from conventional infra-structure that utilizes a minimum of power to obtain a sample extracted from a source such as a pipeline or well-head, conditions the extracted sample, transmits the conditioned sample through vacuum jacketed tubing to an analyzer while maintaining the sample at a temperature and pressure preventing phase transition, condensation or component partitioning.

摘要:
Provided is a precisely sized, inert, non-corrosive volumetric insert for a composite gas accumulator dimensionally conforming to the cross-sectional area of the accumulator and having gas mixing channels where one or more of the inserts is deployable to reduce the interior volume of composite gas accumulator for composite sample collection from transfer processing of smaller LNG transport vehicles whereby a standard size accumulator system can be used without the need to maintain extremely high gas pressure to prevent Joule-Thompson condensation.
