System for sulfide treatment in oilfield systems

A system of continuous production and injection of acrolein containing fluid for the treatment of sulfides, the system comprising:

• a feedstock container comprising a non-aqueous glycerol;
• at least one injection pump to pull the non-aqueous glycerol from the feedstock container through a conduit;
• a tubular reaction chamber in liquid communication with the conduit and receiving the non-aqueous glycerol via the at least one injection pump, wherein the tubular reaction chamber comprises a wall, wherein the tubular reaction chamber is immersed in a heat transfer liquid held in a vessel, and wherein the heat transfer liquid heats the wall of the tubular reactor to a temperature sufficient to cause at least one heteropolyacid catalyst mixed with the non-aqueous glycerol to dehydrate the non-aqueous glycerol into acrolein, and insufficient to vaporize the non-aqueous glycerol or acrolein;
• a liquid-liquid heat exchanger in communication with the tubular reaction chamber which receives and cools the mixture to a temperature of less than 150° C.;
• and
• an air-liquid exchanger in communication with the liquid-liquid heat exchanger which receives and cools the mixture to a temperature of less than 38° C.
