PETROLEUM STREAM ANALYZER

摘要

The petroleum stream analyzer includes a test cell, a neutron source bombarding the petroleum stream flowing through the test cell with fast neutrons, which are slowed down and thereafter engaged in thermal neutron capture reaction with materials in the petroleum stream, and a gamma ray apparatus including a detector providing an energy spectrum of gamma rays from the materials. Shielding material separates the neutron source from the detector and a housing located within the test cell houses the neutron source, the detector and the shielding material such that a longitudinal axis of the housing, which is substantially aligned with the axial flow of the petroleum stream in the test cell, passes through the neutron source, the shielding material and the gamma ray detector. The analyzer also includes apparatus for deriving a measure of a characteristic of the petroleum stream in accordance with the obtained gammy ray energy spectrum.
