Sulfur solubility in gas measurement system

A system for measuring the sulfur solubility of a test gas at a test temperature, comprising:

• a source of the test gas;
• a first station in fluid communication with the source of test gas, the first station comprising a first conduit packed with elemental sulfur, wherein the first conduit is maintained at conditions sufficient to result in the uptake of elemental sulfur by the test gas as the test gas flows through the first conduit, the uptake of elemental sulfur being in excess of the natural equilibrium solubility level of the elemental sulfur in the test gas at the test temperature;
• a second station comprising a second conduit in fluid communication with the first conduit, wherein the second conduit is maintained at conditions sufficient to lower the temperature of the test gas to the test temperature, whereby the amount of elemental sulfur in the test gas is reduced to its natural equilibrium solubility level in the test gas at the test temperature;
• and
• a third station comprising a third conduit in fluid communication with the second conduit, wherein the third conduit is maintained at conditions that cause deposition of the elemental sulfur from the test gas, the third conduit being configured such that the deposited elemental sulfur can be collected and weighed to calculate the sulfur solubility of the test gas based on a measured flow rate of the test gas through the system;
• and
• a fourth conduit in fluid communication with the source of test gas and upstream of the first conduit, wherein the conditions of the fourth conduit are sufficient to saturate the test gas with water as the test gas flows through the fourth conduit prior to entering the first station.
