The HVO production unit is one of the refineries' pollutant units, which often has a CO, THC, NOx, SOx and CO emissions higher than the standard limits. By investigating the operational parameters and determining their effect on pollutants, the viscosity of the feed was determined as one of the important parameters and evaluation measure. The emitted amount of CO pollutant was measured in several feeds with different viscosity characteristics, by decreasing the pollutants temperature, changing combustion chamber temperature(energy consumption)and adjusting other process and production conditions in two product categories: HHVO, LHVO. The amount of CO pollutant emission from LHVO production process is far less than the HHVO production and this amount is reduced by increasing the viscosity of the feed and reducing the outlet pollutant temperature of the reactor. For example the amount of CO emission in same operational condition is 1280 mg/nm3 for LHVO process but for HHVO process is 1740 mg/nm3 and the amount of this pollutant is 1619 mg/nm3 for HHVO process in normal emission process but decrees of pollutants temperature has resulted in decrease of emission to 690 mg/nm3. Finally, the results was analyzed and reported in accordance with the specified parameters.
