Ethoxylation/Propoxylation

Plant for the production of a wide range of non-ionic surfactants based on the condensation of EO/PO with organic substrates.Desmet Ballestra has developed for many years a safe, cost effective, flexible know-how for the design and supply of ethoxylation plants for the production of a large number of non-ionic surfactants, using all main raw materials such as:

  • fatty alcohols
  • nonylphenols
  • fatty amines
  • fatty acids
  • alkylol - amides
  • castor oil
  • glicerides

Desmet Ballestra know-how covers the design and operation of the ethoxylation plant from the ethylene (propylene) oxide handling, up to the final products flaking and finishing。

Desmet Ballestra makes also available an extensive know how on products formulation, application and marketing.

Desmet Ballestra ethoxylation technology has been applied in several plants installed worldwide some of which are successfully in operation for more than 15 years.

Ethoxylation capacity of the plants supplied by Desmet Ballestra ranges from pilot plant size up to 100,000 Tons per year with up to 12 reactors operating in parallel and making different products.

The ethoxylated products can contain in the molecule a number of moles of ethylene oxide ranging from one to hundreds and they are used for a wide range of application such as:

  • Detergent and cosmetic industry
  • Oil-drilling and recovery
  • Fiber treatment
  • Industrial lubrication
  • Waste water treatment
  • Textile auxiliaries
  • Leather industry
  • Polymerization aids

The typical ethoxylation plant configuration is composed of the following sections:

  • Ethylene (and propylene) oxide storage area
  • Ethoxylation (propoxylation) reaction
  • Product finishing/flaking
  • Tank farm (raw materials final & intermediate products)
  • Exhaust gas treatment
  • Fire-fighting system
  • Utilities (steam generation,cooling water system, compressed air, nitrogen)
  • Computer control system and emergency shut-down system
