DE-PM, DE-SOX, DE-NOX SIMULTANEOUS REDUCTION SYSTEM

摘要

PURPOSE: A system for de-particulate matter(PM), desulfurization, and denitrification is provided to save costs required for installation and operations by reducing the entire size of the system. CONSTITUTION: A system for de-PM, desulfurization, and denitrification includes a PM eliminating unit(100), a spraying member(220), and a selective catalytic reduction(SCR) unit(300). The PM eliminating unit is installed on an exhaust gas line(L) for discharging exhaust gas from the exhaust gas discharging facility of an offshore or onshore plant. The PM eliminating unit eliminates PMs from exhaust gas. The spraying member is arranged at the exhaust gas line at the front side of the PM eliminating unit. The spraying member sprays ammonia or urea in order to implement desulfurization in addition to a PM eliminating operation in the PM eliminating unit. The SCR unit is installed at the exhaust gas line at the rear side of the PM eliminating unit. The SCR unit implements denitrification with respect to the exhaust gas.
