A process for continuous, on-demand production of dilute acrolein liquid on-site, at or near the point of acrolein injection, by the liquid dehydration of glycerol in an improved tubular reactor where non-aqueous glycerol is combined with a heteropolyacid catalyst, including silicotungstic acid, phosphotungstic acid, or phosphomolybdic acid. The acid catalyst is evenly dissolved and dispersed in the glycerol upstream of the reactor vessel. The reaction is conducted in a tubular reactor which is heated to an elevated reaction temperature. The dilute acrolein produced in the tubular reactor is directed downstream, optionally through a liquid-liquid heat exchanger and then an air-liquid heat exchanger to reduce temperature, and then diluted prior to being injected into sulfide contaminated systems (such as oil & gas water floods, water disposal systems, producing oil wells, and fuel oil storage) via a pressure conduit.
