The Crude Problem

Online H2S analysis is required to determine how much processing a specific crude stream requires and to differentiate crudes by commercial value.

BUT

Oil naturally contains aromatic compounds that absorb heavily in the UV range (blocking signal). To complicate matters, heavier crudes are too dark and dense to transmit a light signal.

What is ‘Headspace?’

Headspace sampling is designed to strip H2S out of an opaque liquid process such as crude oil.

A column of the liquid sample is heated such that H2S (low boiling pt) evaporates out of solution while the interfering components (high boiling pt) in the crude remain in solution.

A carrier gas is sent through the column to collect H2S vapor and bring it into the flow cell.
