The waste heat generated is utilized as a heat source in the urea synthesizing process. When this urea process is out of operation or in an unstationary state, the crude gas is fed to other waste recovering or cooling process. Thus, ammonia and urea are produced combinedly.OOSAKI KOUZOU...

PROCESS AND PLANT FOR AMMONIA-UREA PRODUCTION A process for ammonia-urea production where: liquid ammonia produced in an ammonia section is fed to a urea section directly at the ammonia synthesis pressure, and where the liquid ammonia is purified at high pressure with the steps of: ... F ...
Urea is made by reacting a gaseous mixture containing ammonia and carbon dioxide in a molar ratio greater than 2:1, at 180-240 DEG C. and at a pressure in the range 180-300 kg./cm.2 gauge and (i) freeing the reaction product of approximately 30% by weight of unreacted ammonia by ...

Hepatic encephalopathy is a neuropsychiatric complication of liver disease which is partly associated with elevated ammonemia. Urea hydrolysis by urease-producing bacteria in the colon is often mentioned as one of the main routes of ammonia production in
(40 mg/kg, i.p. for 2 days), a selective and potent OGA inhibitor16. Despite reduced OGT expression that is consistent with previous studies17, Thiamet-G resulted in increased hepatic protein O-GlcNAcylation (Supplementary Fig.3c) and15N-urea production (Fig.3e), and clinically relevant ...
seasons also have effects on NH3production. Modern ventilation systems can minimize NH3in enclosed production spaces quickly but increase its emissions to the environment. NH3adversely affects the ecosystem, environment, and health of birds and people. Less than 10 ppm is the ideal limit for exposure...
