(IT-NEWSWIRE.COM, September 15, 2015 ) Portland, OR --
Bulletin on Total Emission-reduction Examination of Key Pollutants in China 2013 issued by Ministry of Environment Protection of PRC shows: the discharge of chemical oxygen demand, ammonia nitrogen, sulfur dioxide and nitrogen oxides dropped over the same period of last year.
Bulletin suggested: in 2013, the total discharge of chemical oxygen demand was 23.527 million t, decreasing by 2.93% over last year; ammonia nitrogen was 2.457 million t, decreasing by 3.14%; sulfur dioxide was 20.439 million t, decreasing by 3.48%; and nitrogen oxides was 22.273 million t, decreasing by 4.72%.
In addition, in petroleum refining industry, 18 sets of catalytic cracking units with total capacity of 31.5 million t newly build desulphurization devices, accounting to 18% of total capacity in China; conversion engineering of coal to gas newly adds gas consumption for 2.6 billion m3, substituting raw coal for 4.9 million t.
