Please ask an expert to answer questions regarding the torch

See if a reaction occurs between them to form crystals. For example, when ammonia and hydrogen sulfide meet within the flare line, they will crystallize and block the pipelines.

Three separate torches need to be installed; it is not possible to combine them into one. Chemical reactions and crystallization occur between the different media, and their burning characteristics also vary. Also, this can only be used for elevated torches; hydrocyanic acid is highly toxic, so ground-based torches cannot be used. Removable torches are relatively expensive; fixed towers can be used instead.

1. The principle of torch design is: \"separate by quality and pressure.\" Based on the composition of the exhaust gases specified by the poster, 3 flares are required, namely: an ammonia flare, an acidic gas flare, and a general-purpose flare. 2. Toxic and harmful gases such as ammonia and hydrocyanic acid in the exhaust gases should not be released through the ground; instead, they must be burned and emitted via elevated flares. However, propylene, acrylonitrile, etc. can use ground flares. 3. If the design adopts three overhead flares, and considering the asynchronous nature of shutdowns and maintenance for various units, \"removable overhead flares\" can be used. Although the initial investment is higher, the benefits resulting from a single production shutdown for maintenance or operation are sufficient to offset the cost of these removable overhead flares. 4. Recommended reasonable design approach for flares: Install overhead flare stacks on a common framework outside the plant area (ammonia flares and cyanide flares), and ground flares within the acrylonitrile plant.

It is recommended to set them separately; since the physical properties and toxicity of the media vary, it is best to use elevated, detachable torches, with a tower being sufficient for one of them.
