GASOLINE BLEND SPOT SAMPLING SYSTEM AND METHOD

摘要

A gasoline blend spot sampling system and method including an adjustable volume mechanism for retaining an adjustable volume of gasoline for sampling, a coolant system integrated with the adjustable volume mechanism, and a sample collection assembly using a blunt-end tube for use with an open-mouthed bottle. Various three-way valves are actuated to route gasoline through various stages of a sampling process, from a gasoline fast loop to a purge loop to a gasoline capture stage to a sample bottling stage.

主权项

1. A spot sampling system for use with a source of gasoline and a source of coolant comprising:
an adjustable volume mechanism including:
a sample chamber in fluid communication with the source of gasoline,a piston movable within said sample chamber to adjust the fillable volume of the sample chamber and to expel contents of the sample chamber as required, and a coolant cavity in fluid communication with the coolant source, said coolant cavity being positioned in proximity to the sample chamber for cooling the sample chamber and any contents thereof; a heat exchanger in fluid communication with the coolant source and the gasoline source; and a sample collection assembly in fluid communication with the adjustable volume mechanism, said sample collection assembly including:
an open-mouthed sample bottle,a bottle receiving mechanism to receive the specimen bottle for filling, anda blunt tube which extends through the open mouth of the sample bottle when the open-mouth sample bottle is engaged with the bottle receiving mechanism.
