Abstract:
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.
Abstract:
A system and method for conditioning of very low pressure gas samples extracted from a source, heating the samples, boosting the pressure to a level appropriate for analysis, regulating the gas sample temperature and pressure to prevent dew-point dropout from Joules Thompson condensation, and passing the gas sample to an a remotely located analyzer or analyzer array where the electrical power for the pressurizing pump and heated regulator is provided by heat tracing.
Abstract:
A generally cylindrical, elongated thermal isolator for in-line placement proximate to a vaporizer of a sample take-off conditioning system for minimizing upstream heat migration from a sample vaporizer to prevent liquid sample pre-vaporization.
Abstract:
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.
Abstract:
A vacuum jacketed gas line adaptor with a flange cover for an existing pipeline sample take-off probe encasing a sample line and hermetically sealed to a vacuum valve housing having an sealable access port and containing a vented bleed valve and a block valve, fluidly connected to the sample line and a length of vacuum jacketed tubing sealing connected to the valve housing and in vacuum communication therewith, where the vacuum jacketed tubing surrounds the sample line to provide thermal isolation from the ambient for the sample line to a sample vaporizer.

Abstract:
A sampling system for collecting periodic composite and/or non-composite samples of vaporized gas during a transfer process from a vaporizer of a cryogenic hydrocarbon liquid including 1) a direct sample pathway to a gas analyzer for instantaneous, real-time vaporized gas analysis, 2) a speed loop pathway for directly collecting fresh vaporized gas samples for subsequent analysis, and 3) a composite sample pathway including a pressurized sample accumulator for collecting a plurality periodically obtained samples of a select volume during the transfer process to create a composite sample of the vaporized gas.

Abstract:
A sample take-off system incorporating a small volume pump with a speed loop for pressurizing excess extracted sample for return into the process stream using a single multi-channel probe for both take-off and return of the excess extracted sample is illustrated and described.
