Carbamate production method, isocyanate production method, carbamate production device and isocyanate production device |
| abstract |
The disclosed carbamate production method is provided with a urea-producing process, a carbamation process, an ammonia-separating process wherein gas is absorbed in water in the presence of carbonate salt to form water with absorbed gas and to separate ammonia, an aqueous alcohol solution-separating process that separates an aqueous alcohol solution from the water with absorbed gas, an ammonia/carbonic acid-separating process wherein carbonic acid gas is separated from the aqueous ammonia solution in the water with absorbed gas from which the aqueous alcohol solution was separated, and an aqueous ammonia solution re-using process that mixes the aqueous ammonia solution and carbonate salt with water for use in producing the water for gas absorption. |
