Integrated ammonia and urea plant and method of integration of the work

摘要

The invention relates to a common ammonia element engineering and a complete set of equipment for executing the project.According to the project, most of the high-pressure purification flow, which is composed of air, is recycled by the heating medium in the synthetic gas manufacturing device of ammonia process.If this method is used, part of the high-pressure air supplied through the heating reactor is acted by the element purification flow circulation, so the compressed energy required for ammonia synthesis can be calculated.In addition, in order to purify the elements, there is no need for equipment.
