Description

Technical Field

[0001] The utility model relates to the technical field of synthetic ammonia, in particular to a decarbonization flash steam recovery device. Background Art

[0002] Most of the synthetic ammonia production in my country uses solid fuel to produce synthetic ammonia raw gas, that is, in the gasification furnace, oxygen in the air is used to react with the red-hot carbon layer in the furnace to produce an oxidation reaction, releasing a large amount of heat energy, which is stored in the carbon layer. When the temperature in the furnace reaches a certain value, water vapor is used to pass through the red-hot carbon layer to absorb heat and decompose CO+H2. When the furnace temperature is low, air is blown in again to increase the furnace temperature. This cycle is called fixed-bed intermittent gasification method. In the existing production process, the liquid released from the decarbonization section is directly discharged without any treatment after flash evaporation in the high flash tank (i.e., decarbonization flash gas), which has many shortcomings; the decarbonization flash gas still contains some CO2, H2 and N2. Direct discharge causes CO2 to be discharged into the atmosphere, increasing the atmospheric greenhouse effect, which is not good for the environment. H2 and N2 are the main raw materials for synthetic ammonia. Discharging leads to energy waste, increased production costs, and is not conducive to energy conservation and environmental protection.

[0003] For example, the publication number CN201120023210.4 discloses the "Synthetic Ammonia Decarbonization Flash Steam Recovery Device". The decarbonization flash steam in the synthetic ammonia production process enters the high-pressure flash steam absorption tower, and is fully contacted with the propylene carbonate solution from the decarbonization pump. The decarbonization liquid absorbs the CO2 gas in the flash steam. After the CO2 is removed, the flash steam is purified and separated by the washing tower and the separation tower, leaving only H2 and N2. After being compressed by the hydrogen and nitrogen compressor, it can be reused as a raw material for synthetic ammonia. In addition, the propylene carbonate liquid that has absorbed the CO2 gas passes through the low flash tank and the normal solution tower to obtain CO2 gas with a purity of more than 95.7%, which can be directly sent to the urea section and used as the raw gas for producing urea.

[0004] However, when steam is recovered, the steam will carry a large amount of hot gas for synchronous recovery, and the hot gas will increase the load on the transmission pipe and cause the transmission pipe to shake, thereby reducing the life of the transmission pipe. At the same time, it is easy to cause the transmission pipe to break, which in turn leads to the collapse of the transmission pipe and the leakage of steam, thus affecting the recovery efficiency.
