Material distribution in the intermittent water-gas generation process for ammonia synthesis
Thread Content
In the process of producing water gas for ammonia synthesis using a batch method, the distribution of materials is as follows: out of 100 kg of coal, 61.26 kg is used to produce water gas, while 38.74 kg is used to produce blast gas. I would appreciate it if someone could explain why this distribution is used; an urgent answer is needed. Among these, it is necessary to know the composition of the raw materials, the composition of water gas, the composition of the blowing gas, and the composition of the ash. The data comes from chemical engineering software. Synthetic ammonia gas generation section, material balance. This post was last edited by liuwenqiu on 2009-3-4 20:00]
It’s the result of long-term practice; there’s no reason for it
It should refer to the carbon in the gasified portion; theoretically, one and a half cubic feet of water gas require one cubic foot of air, resulting in approximately one cubic foot of purge gas. Composition of semi-water gas: CO: 30%, CO2: 8%, CH4: 1%. Blowing gas composition: CO2: 15%, CO: 6%. Assuming that the volume of water gas produced per hour is 6,000 cubic meters and the volume of blowing gas is also 6,000 cubic meters, the molar volume can be calculated based on the gas composition; from this, the mass of carbon atoms in the semi-water gas and the blowing gas can be determined. After making some calculations, the results differ from your data.
The blowing is mainly used to provide heat for the gas production that follows; according to the heat balance, that much carbon reaction is required – that’s probably how it works.
What’s on the third floor is semi-water gas? What is the composition of water gas? ? ?
