What is the function of the C4 deammoniator in the MTBE plant?
Thread Content
For a new MTBE plant, the C4 stream must pass through a filter and an ammonia remover before entering the C4 feed tank. What is the function of the C4 ammonia remover? Why don’t older devices have this equipment? Is it due to product quality requirements?
Ensure low levels of carbon tetra impurities in the raw materials, thereby protecting the catalyst
What impurities does the C4 deamidator remove?
It is estimated that the upstream unit has a decarburization process to minimize the alkaline nitrogen in the MTBE feedstock and prevent poisoning of the acidic catalyst.
Reduce basic nitrides in the MTBE feedstock to protect the resin catalyst. Some devices have it.
It depends on the raw materials; if there is a high amount of basic nitrogen in the raw materials, it is essential, as the MTBE catalyst (acidic resin) will definitely become poisoned when exposed to basic nitrogen
