摘要： A method of and apparatus for determining the concentration of sulfur atoms in a plurality of the same or different combustible molecules in a fluid by burning a measured quantity of the fluid and analyzing the combustion products of said measured quantity of the fluid by the use of at least one equipment of the group including, but not limited to, a coulometric titrator and a photometer. It is practically impossible to detect, for example, COS and CS2 in natural gas by the use of a coulometric titrator. However, by burning the natural gas, each sulfur atom in the COS and CS2 combines with two oxygen atoms to form SO2, the concentration of which can be measured with a coulometric titrator. This is important for a number of reasons. For example, it is important to know the sulfur atom concentration in natural gas or liquified petroleum gas used in hydrogen production. Information obtained by monitoring the sulfur atom concentration enables operating personnel to take steps to increase efficiency and to prevent expensive catalyst damage or decomposition in such hydrogen production. The ecological advantages of monitoring the sulfur atom concentration in natural or other gas are selfevident.

摘要： An apparatus for reducing the concentration of a constituent in a fluid. A portion or all of the constituent is removed from a portion of the fluid and the constituent free portion is remixed with constituent containing portion. In a flowing system, a limited range electrolytic titrator may analyze the mixed output when the input concentration varies over a very large range. The apparatus of the invention may include a three way valve to pass the input thereto either through a filter or through a bypass. The three way valve may be a solenoid valve operated by a pulse generator. A needle valve may be employed in the bypass, but need not be employed at all in many cases. If a single conduit from where the filter and bypass outputs join is not fairly large or long, preferably a mixing tank or other mixing device is provided.

摘要： A selective method of removing sulfur dioxide from flue gases or the like containing both sulfur dioxide and hydrogen sulfide without removing the hydrogen sulfide by bubbling the flue gas through about a 5-95 percent solution of an organic acid and an alkali metal salt of the said acid. The acid is selected from the group of: citric malic, lactic, succinic, ascorbic and tartaric. The acid is preferably citric and the alkali metal is preferably potassium. The ratio of the weight of the salt to that of the acid may be within the range of about 1s: 2a to 6s: 1a as such as is needed to make the solution pH between about 4.0 and 6.0, where s and a are one mole each of said salt and said acid, respectively. The said ratio preferably is 5s:1a or the pH is preferably 5.7.
