The issue of utilizing the low-energy content of urea
Thread Content
Are there manufacturers that use technologies such as lithium bromide for the utilization of low-grade energy? It is widely used in small and medium-sized urea plants; it seems to be less used in large-scale facilities. I have been quite interested in this recently; please reply as follows: 1. Process to be used: 2. Plant scale: 10,000 tons 3. Low-grade heat source: 4. Technology to be employed: 5. Purpose: Last edited by cthlj2007 on 2009-4-3 09:12]
1. Plant capacity: 150,000 tons. 2. Low-enthalpy heat source: hot water. 3. Technology used: lithium bromide. 4. Purpose: to reduce the temperature of the decarbonized PC lean solution.
We are also preparing to get started. We’re not sure how to determine the power rating of the refrigeration units; it seems that using hot water in most cases isn’t very effective. We’re not sure if this is the case. [This post was last edited by lxq700918 on 2009-4-5 at 13:11]
