| Abstract: | A presentation is given of the use of the CO2 stripping urea process with high- efficiency condensation and low mounting height in the expansion and renovation of the traditional aqueous solution total recycle urea unit. After the modification the capacity of the urea unit is increased from 100 kt/a to 150 kt/a, the steam consumption is lowered by 0.4 t per ton of urea, cooling water by 50 t, and electricity by 30 kW · h. An analysis of investment, plant consumption and economic benefit shows the total investment of the project is about 54 million yuan and can be recovered within 3.3 years after commissioning. |
