The disclosure pertains to a high pressure carbamate condensation apparatus for a urea plant, a urea plant, and a urea production method. The apparatus comprises a first U-shaped tube bundle arranged around a second U-shaped tube bundle.

High pressure carbamate condensation apparatus

The disclosure pertains to a coupled plant process for the production of urea and melamine, with a urea synthesis section with HP COstripping, and with a part of the COfeed supplied to a recovery section.

Coupled urea melamine production with HP COstripping

A method is disclosed for stripping in a stripper a urea synthesis solution received from a urea forming process wherein ammonia and CO2 are reacted under urea forming conditions. The shell space of the stripper comprises a continuous vertical zone.

Urea plant with stripper and stripping method

Process for the production of urea from ammonia and carbon dioxide in a urea plant containing a high-pressure synthesis section comprising at least one reactor section, a stripper and a condenser wherein all the high-pressure equipment is placed in a low position, wherein the height of the high-pressure section is less than 35 m from ground level and at least one of the reactor sections comprises means for the separate distribution of ammonia in the bottom of the reactor section.

Process for the production of urea from ammonia and carbon dioxide

Process for the production of urea from ammonia and carbon dioxide in a urea plant containing a high-pressure synthesis section comprising two reactor sections, a stripper and a condenser, and a recovery section, wherein in the first reactor section a first synthesis solution is formed that is fed to the second reactor section; fresh carbon dioxide is fed to the second reactor section and in the second reactor section a second synthesis solution is formed that is fed to the stripper, wherein the second synthesis solution is stripped with the use of carbon dioxide as stripping gas and the mixed gas stream obtained in the stripper is sent to the condenser together with fresh ammonia and a carbamate stream, whereafter the condensate that is formed in the condenser is fed to the first reactor section and the urea stream that is obtained in the stripper is further purified in the recovery section, wherein the flow of the first synthesis solution from the first reactor section to the second reactor section, the flow of the second synthesis solution from the second reactor section to the stripper, the flow of the mixed gas stream from the stripper to the condenser and of the condensate from the condenser to the first reactor section is a gravity flow.
