Spectroscopic crude oil analysis

摘要

A spectroscopic sample analysis apparatus includes an actively controlled heat exchanger in serial fluid communication with a spectroscopic analyzer, and a controller communicably coupled to the heat exchanger. The heat exchanger is disposed downstream of a fluid handler in the form of a stream selection unit/stream switching unit (SSU), a solvent/standard recirculation unit (SRU), and/or an auto-sampling unit (ASU). The SSU selectively couples individual stream inputs to an output port. The SRU includes a solvent/standard reservoir, and selectively couples output ports to the heat exchanger, and returns the solvent/standard sample to the reservoirs. The ASU includes a sample reservoir having a sample transfer pathway with a plurality of orifices disposed at spaced locations along a length thereof. The controller selectively actuates the fluid handler, enabling sample to flow there through to the heat exchanger, and actuates the heat exchanger to maintain the sample at a predetermined temperature.

1. A system configured for delivering and analyzing crude oil comprising:
a spectroscopic analyzer that detects compositional properties of crude oil; a conduit that allows fluid communication with the spectroscopic analyzer, the conduit being configured for receiving the crude oil from a source of crude oil and configured for delivering the crude oil into the spectroscopic analyzer; a heat exchanger in thermal communication with an interior of the conduit that exchanges heat with the crude oil when the crude oil is in the conduit; and a controller configured to actuate the heat exchanger in order to maintain crude oil that is entering the spectroscopic analyzer from the conduit at a set point temperature.
