Automatic nitrogen fixation and ammonia production method

Abstract

The invention discloses an automatic nitrogen fixation and ammonia production method. The automatic nitrogen fixation and ammonia production method comprises the following steps of: adding a nitrogenfixation solution into a reactor; taking a high-valence compound of nitrogen as an additive and controlling the pH (Potential of Hydrogen) of the solution to be 1 to 5 and the temperature to be 40 to95 DEG C; taking the solution and checking whether ammonia is generated or not. The invention develops a novel ammonia production method; the prepared ammonia has a good desulfurization effect, zero emission can be basically realized and the desulfurization cost can be remarkably reduced; the occupied area of equipment can be obviously saved and a reliable theoretical foundation and powerful experiment evidence are provided for how to accurately grasp and flexibly apply the conditions and laws to production and living services.

Description

technical field [0001] The invention relates to the preparation of ammonia, in particular to a method for automatic nitrogen fixation and ammonia production. Background technique [0002] As we all know, in the field of environmental protection, the ammonia method of flue gas desulfurization often directly uses liquid ammonia or ammonia water as a desulfurizer. Due to the low boiling point of ammonia, it is extremely volatile especially at high temperatures (usually above 120°C) in the flue gas. It will inevitably lead to a series of problems such as low ammonia utilization rate, poor effect, high cost, large land occupation, high investment, serious secondary pollution, and dirty working environment, and these problems are not easy to overcome. In the prior art, there have been reports of using superheated steam to hydrolyze urea to produce ammonia. However, the superheated steam method also has problems such as high energy consumption, large area occupation, and large inve...
