Page 10: Equipment Overview
H2S. The total sulfur option involves the addition of a total sulfur reaction furnace (pyrolysis furnace) to a Model 330S or 331S. The furnace converts all sulfur compounds into H2S, allowing the H2S analyzer to read total sulfur as per the ASTM D 4468-85 “Standard Test Method for Total Sulfur in Gaseous Fuels by Hydrogenolysis and Rateometric Colorimetry”. -
Page 11: Total Sulfur Reaction Furnace
Envent Engineering Ltd – Total Sulfur User’s Manual – Revision 4.0 Total Sulfur Reaction Furnace The Total Sulfur option comes standard with furnace temperature control circuitry. It also consists of a reaction oven, flame arrestors, hydrogen and sample flow meters, and an optional 3-way solenoid valve to allow the user to measure both H2S and total sulfur on an alternating basis, or the use of an SDS to measure TS consistency. -

Our calculations are based on a 200 cm /min (flow of 2 on a A- 157-1 flow meter). Assuming each analysis will run 3 times every six hours, Envent suggests the bottle should be checked at least 10 days prior to the estimated end of life. -
Page 13: Unpacking & Installation
Upon arrival, the packaging should be immediately inspected for any external damage that may have occurred during shipping. If any damage is present, please contact Envent Engineering Ltd and request that the carrier's agent be present when the analyzer is unpacked. If a disagreement arises, the incoterms agreed to by the seller and the customer will overrule any dispute. -
