Abstract
Measured sample quantities of sulfureous matter are introduced into a sealed chamber where the samples are pyrolyzed to form sulfur dioxide and sulfur trioxide gases and to oxidize organic substances to form carbon dioxide gas. The gases are then passed through a free sulfur-absorbing packing and into a scrubbing zone wherein transition metal amine complex is used to remove sulfureous compounds without reaction with the carbon dioxide gas. The scrubbed gases are then analyzed to determine the carbon dioxide content thereof.
Claims13
A process for determining trace quantities of organic carbon in sulfureous mixtures and compounds comprising the steps of:
- a. introducing small predetermined sample quantities of sulfureous matter into a first zone of a sealed chamber;
- b. heating the introduced matter in the first zone to a temperature sufficient to decompose the matter to form sulfur dioxide and sulfur trioxide gases and to oxidize organic substances in the matter to form carbon dioxide gas;
- c. conveying aforementioned gases from the first zone to subsequent zones in the chamber;
- d. scrubbing the gases from the first zone in a scrubbing zone by the usage of a transition metal amine complex which reacts to remove sulfureous compounds from the gases without reaction with carbon dioxide gas;
- and
- e. analyzing the gases which exit from the scrubbing zone to determine the carbon dioxide content of the gases.
