Urea Nostalgia

In 1967 Stamicarbon revolutionized the urea process by the invention of the HP CO2 Stripper by Mr. Petrus JC Kaasenbrood. The HP CO2 stripper did lead to following three main benefits:

1. the carbamate could be recycled at synthesis pressure so now extra water needed to be added to recycle the carbamate;

2. no medium pressure recirculation section was needed anymore and

3. with the condensation of strip gasses in the high pressure carbamate condenser low pressure steam could be produced, which could be used in the downstream sections leading to a reduction of the steam consumption of a urea plant of about a factor two.
