The ethoxylation technology for the HH Loop Reactor was developed to handle the safety, productivity, product qualities and environmental aspects. By incorporating these four aspects the loop reactor is today considered the most advanced reactor system and state of the art design for manufacturing non-ionic surfactants such as:

  • Fatty Alcohol Ethoxylates
  • Fatty Acid Ethoxylates
  • Fatty Amine Ethoxylates
  • Alcohol Ethoxylates
  • Alcohol EO/PO Copolymers
  • Nonyl Phenol Ethoxylates
  • Octyl Phenol Ethoxylates
  • BisPhenol A Ethoxylates
  • Castor Oil Ethoxylates
  • Soybean Oil Ethoxylates
  • Sorbitanester, M Ethoxylates
  • Methylester Ethoxylates
  • Thiol Ethoxylates
  • PEGs, MPEGs, BPEGs, PPEGs
  • PPGs
  • Various Propoxylates
  • Polyol Ethoxylates (1,4 Butandiol, TMP, Pentaerythritol, others)
  • Block EO/PO Copolymers
  • Random EO/PO Copolymers

The HH Loop Reactor design is characterized by:

High Pressure Reactor Design 45 barg or 650 psig
High Productivity 8 to 14 batches per day depending upon product
High Growth Ratio industrially designed over 1 to 100
High Ethylene Oxide Addition Rate 1,500 kg/hr m3
High Propylene Oxide Addition Rate    600 kg/hr m3
High Butylene Oxide Addition Rate 1,000 kg/hr m3
Low Side Reactions < 1 ppm EO, < 1-5 ppm dioxane, < 1 % PEG
Low Color Formation typically below 10 APHA depending upon product
