Production system of isopropanolamine

The utility model provides a production system of isopropanolamine. The production system comprises a reaction unit, a deamination unit and a product separation unit which are connected in sequence. According to the utility model, the product obtained by the reaction unit is subjected to flash evaporation and deamination rectification treatment in the deamination unit to remove ammonia in the isopropanolamine product, and then the deaminated product is introduced into the monoisopropanolamine rectifying tower in the product separation unit for rectification treatment to obtain monoisopropanolamine. Compared with the prior art, the production system provided by the utility model is simple in equipment, low in cost and easy to operate, large-scale production is convenient to realize, the selectivity of the monoisopropanolamine can be effectively improved, tests show that the selectivity of the monoisopropanolamine can be improved to 93.3%, and the purity of the monoisopropanolamine is high and is 99% or above.
