Abstract:
This thesis explores the design and simulation of a High-Pressure Urea Synthesis Loop
employing the Stamicarbon Process. The report commences with a meticulous
selection of technology through an extensive literature review, covering fundamental
aspects of Urea synthesis and comparing available technologies, specifically
Stamicarbon and Snamprogetti. The rationale behind choosing the Stamicarbon
process is established, laying the foundation for the planned investigation and future
project direction. The thesis outlines a comprehensive process flow diagram, detailing
Urea production within the High-Pressure Loop. Key raw materials, including
Ammonia and CO2, form the basis of the process, with additional components such as
Water/Steam and Air also the part of the process. Detailed specifications of the
critical equipment within the High-Pressure Loop are provided including, including
the HP Reactor, HP Carbamate Condenser, HP Scrubber, and HP Stripper. Material and
energy balances were carefully examined across the equipment. The High Pressure
Urea synthesis loop is also simulated with the use of Aspen Plus. There was a strong emphasis
on improving the economic aspects of this procedure. Designing and simulating a high
pressure Urea synthesis loop requires selecting the optimal configuration and operating
parameters to reduce overall annual costs.
