Abstract

Способ удаления SOиз потока топочного газа включает в себя обеспечение реакционного соединения, выбранного из группы, состоящей из карбоната натрия, бикарбоната натрия, сесквикарбоната и их смесей. Реакционное соединение инжектируют в поток топочного газа. Температура топочного газа составляет примерно 500 -850°F. Реакционное соединение поддерживают в контакте с топочным газом в течение времени, достаточного для проведения реакции части реакционного соединения с частью SO, для снижения концентрации SOв потоке топочного газа.
