Low environmental effects, low energy consumption, and high yield are advantages with our own proprietary technology for ethanolamines and ethylene amines production.
The development of our proprietary technologies for producing ethylene and ethanol amines based on ethylene oxide can be traced back to the 70’ies. Then the chemists at our R&D department developed new routes for making ethanolamines and ethylene amines. The technology was further refined and developed until industrial production started in 1977. This was the first unit to produce ethylene amines from ethylene oxide and anhydrous ammonia in a full-scale, commercial operation. This manufacturing process consists of two main steps:
- The production of ethanolamines by reacting EO (ethylene oxide) and anhydrous ammonia in the presence of a catalyst followed by the separation of the ethanolamines formed. The main product is MEA (monoethanolamine) and the main co-product is DEA (diethanolamine).
- The production of ethylene amines by reacting MEA from step 1 with anhydrous ammonia in the presence of a catalyst followed by separation of the products. The main co-product is water formed from the reaction between MEA and ammonia or another amine. A range of ethylene amines are formed. The main product is the simplest EDA (ethylenediamine). Other important products are the dimers, DETA (diethylenetriamine), PIP (piperazine) and the aminoalcohol AEEA (aminoethylethanolamine). There are also significant amounts of higher ethanol and ethylene amines formed.
