Recycling carbamate solution back to urea-reactors will be done world-wide more or less exclusively with Körting high-pressure liquid jet ejectors (HP ejectors). Multi-stage steam jet vacuum systems specifically designed to meet the requirements of urea evaporation stages have been in use for many decades now with great success. New developed boosters and vacuum condensers are available to provide an extremely economical and trouble-free operation.
