Design Discussion on CEMS in Liquefied Natural Gas Receiving Station
According to the NOx characteristics of submerged combustion vaporizer(SCV)flue gas in liquefied natural gas receiving station,a continuous flue gas emission monitoring system(CEMS)is designed.The composition of CEMS,the selection of sampling method and analyzer,the setting of flue gas parameter monitoring unit and data acquisition and processing unit are described in detail.The corresponding scheme for CEMS installation and later maintenance are proposed.The system can not only monitor whether the emission can reach the standard or not,but also can monitor the CO concentration in the flue gas to reflect the burnout efficiency of the SCV low-nitrogen burner.The production and maintenance costs are effectively reduced.
