Biogas plant QuenchFlow™

Operations of an ethylene plant generate a massive amount of quench water which contains a complex oil–water emulsion and high impurity content. To meet the treatment needs of this highly polluted stream, Veolia Water Technologies has developed QuenchFlow, a unique, effective, and economical integrated system to clean the contaminated quench water generated from the steam cracking of ethane for ethylene production. An integrated quench water treatment system for ethane cracker plants. Ethylene plants produce significant quantities of polluted waste streams containing: • Oil • Benzene • Styrene • Butadiene • Volatile organic compounds (VOC) If the suspended solids and hydrocarbons in the quench water are not properly removed, they may react in the dilution steam system downstream causing fouling of heat exchangers and increased energy consumption. Over time, this increase in steam usage reduces efficiency and leads to higher operating costs affecting the economic and environmental performance of the cracking furnace operations. Therefore, the purification of quench water for steam regeneration is important to avoid process upsets that threaten to foul processing equipment and disrupt stable ethylene production. To meet your oil and gas needs of improving the challenging quench water treatment in the hydrocarbon/chemical processing industry, Veolia Water Technologies developed QuenchFlow, an efficient solution for ethylene plants.
