Tianjin Petrochemical did five full years of work improving its energy consumption, emissions, and efficiency to qualify for a clean production enterprise rating and, on Dec. 21, passed a Tianjin Municipal Economic Commission appraisal. To achieve this, in addition to the hard work, the company developed 13 emissions and consumption reduction projects in 2007, in accordance with national laws. These included 500000 tons/yr of electric desalting, a coal-fired boiler desulphurization system, sewage disposal online monitoring, putting sewage through a treatment plant, and crude oil floating roof. There was a substantial decrease in polluting emissions, while production was brought in line with national clean production standards. Moreover, the changes significantly reduced overall energy consumption and improved profits from sales. The appraisal committee decided that the company deserved the honor.
