Overview

What is this invention?

Method of flue gas denitrification

Denitration is an important step in the gas processing industry, and China Petroleum & Chemical Corporation has developed a new method for denitrating flue gas. The new technique involves passing flue gas through a series of catalyst beds from the bottom to the top, where each bed contains both a catalyst support component and a granular denitration catalyst. This moving material helps to break down polluting molecules into smaller pieces that can be eliminated from the atmosphere.

The denitration reactor in this method allows flue gas to pass through a plurality of catalyst beds from the bottom to the top. Each bed contains a catalyst support component and a granular denitration catalyst that is stacked on the support component. The catalyst falls between every two adjacent beds, making it travel along the support components reciprocatively.

  • Catalyst beds

  • Granular denitration catalyst

  • Catalyst support component

  • reciprocating

Other similar products on the market include scrubber technology and catalytic reduction systems.

This novel method of denitration has many potential applications. For example, it could be used to clean up harmful nitrogen oxides emissions from industrial facilities. Additionally, it could also be employed in the production of ammonia by-products from fertilizer plants and other chemical factories. Finally, this technique could also be used in the removal of sulfur dioxide and other pollutants from power plant flue gas streams.

There are a few risks associated with this method. One is that if the beds are not maintained properly, the catalyst may become coated with impurities and cease to function. Additionally, improper installation or operation of the denitration reactor could lead to excessive emissions from the plant.

The product is easy to use and fits well in the space. It has a good odor, but it does not leave any residue on surfaces. Overall, I am satisfied with the product.

There once was a way to denitrate
 Flue gas, by passing it through some beds.
 The catalyst support component moved
 And the granular denitration catalyst too.
 Between every two adjacent beds,
 The GDC would fall from one to the other,

USPTO Abstract > A method for flue gas denotation includes the step of, in the presence of ammonia, enabling flue gas in a denitration reactor to pass through a plurality of catalyst beds from the bottom to the top to participate in a denitration reaction. Each catalyst bed contains a catalyst support component and a granular denitration catalyst stacked on the catalyst support component, and, in every single catalyst bed, the granular denitration catalyst moves along a same direction on the catalyst support component. Between every two adjacent catalyst beds, the granular denitration catalyst falls from the tail of a previous catalyst support component to the head of a next catalyst support component, making the granular denitration catalyst travel along the catalyst support components reciprocatively.A method for flue gas denotation includes the step of, in the presence of ammonia, enabling flue gas in a denitration reactor to pass through a plurality of catalyst beds from the bottom to the top to pa...
