After Low NOx Combustion Technologies, if the NOx level still cannot meet the emission standard or total emissionreduction requirement, the unit should install flue gas deNOx facility.
当采用低氮燃烧技术后，氮氧化物排放浓度不达标或不满足总量控制要求时，应建设烟气脱硝设施。

The stronger the abatement actions are, the higher the macroeconomic cost of per unitemissionreduction would be.
而且减排的力度越大，相应的单位减排的宏观经济成本越高。

Reduction of sulfur emission can be achieved via strengthening the desulfurization efficiency of the refining dry gas and LPG and increasing the sulfur reclamation of the sulfur recovery unit.
