March 26, Sinopec announced that will start the "clear water and blue sky"
large-scale public action, for the four and above the heavy diesel vehicles,
free filling a total of 8000 tons, about 80 million barrels, value 4000 million
yuan of diesel exhaust treatment liquid, to encourage diesel vehicles to
accelerate the pace of upgrading.
It is
reported that Sinopec will throughout the 5000 seat Sinopec gas station, for the
installation of SCR system of heavy-duty diesel vehicle free charging diesel
engine exhaust treatment liquid, to guide social attention diesel vehicle
emissions, encourage diesel vehicles to accelerate the pace of upgrading,
promote the use of four or more emissions heavy-duty diesel vehicles and
supporting treatment of tail gas from liquid.
Sinopec
for the installation of the SCR system of heavy-duty diesel vehicle free
charging diesel engine exhaust treatment solution, to guide social attention
diesel vehicle emissions, encourage diesel vehicles to accelerate the pace of
upgrading, promote the use of four or more emissions heavy-duty diesel trucks
and matching of tail gas treatment fluid.
Heavy
duty diesel vehicle emission is the most important of vehicle
management.. Heavy duty
diesel vehicles accounted for only 5.6% of the recoverable amount of the
automobile, but the nitrogen oxides (NOx), and particulate matter (PM) emissions
has accounted for the total emissions of cars 67.7% and 78%, according to the
Ministry of environmental protection the Chinese motor vehicle pollution
prevention and control annual report (2013) ". That is, heavy diesel vehicles in the
motor vehicle, is the main source of NOX and PM emissions.
According
to the Ministry of public information announcement, since January 1, 2015, the
new production and sales of heavy-duty diesel vehicles must meet the country's
four emission standards. But the current state three and the
following diesel vehicles out too slow, the country four and the proportion is
very low. To achieve this
standard, heavy-duty diesel vehicles in upgrading engine modification based on,
the world's major two technical routes, one is selective catalytic reduction
(SCR), second is the exhaust gas recirculation particulate trap (EGR
DPF). The advantages of
SCR, first in the engine through high temperature and high pressure PM
combustion elimination, by diesel exhaust treatment solution NOx, also has to
improve fuel economy, China's automobile production enterprises the main
selection technique route.
Lv
Dapeng, spokesman for Sinopec, said heavy diesel exhaust emissions are
particularly serious pollution in the motor vehicle, speeding up governance is a
priority. State four
emission standards for diesel engine upgrade the engine and the use of SCR
revolutionary technology. The significance of reducing the
pollution of automobile tail gas is of special significance.. If the country and before diesel car
is "wok cooking", then the lid tight again, will take a "smoke", namely exhaust
pollution dye. To the
country four and above emission standards for diesel engine is also a route,
like the "pressure cooker", the main two pollutants of PM in the engine by high
temperature high pressure is eliminated, while NOx is by diesel exhaust
processing liquid reduction treatment, can realize the harmless, achieve the
four or five national emission standards.
Engaged
in long-term diesel engine exhaust treatment research senior chemical expert
Qiao Yingbin appeal, with policy to encourage diesel engine to accelerate the
upgrade. He said the
country's four heavy-duty diesel NOX emissions than the country three of heavy
duty diesel car 30%, PM decreased by 80%. However, the country has a low rate of
four cars, should study and formulate the replacement subsidy policies for four
heavy diesel vehicles, accelerate the elimination of old diesel vehicles,
significantly reducing diesel exhaust pollution. At the same time urge the relevant
enterprise to do a good job of diesel engine exhaust gas treatment liquid
production supply, guide and standardize the use of liquid.
China
Commercial Press published "diesel exhaust treatment liquid baiwenbaida" a book
lists with SCR system and diesel car tail gas treating liquid the three major
benefits: one is particulate matter emissions can be substantially reduced, meet
the State IV emission standards; second is in the tail gas nitrogen oxide and
80% can be converted to nitrogen gas, can achieve the four or five national
emission standards; the third is the machine in high temperature combustion and
improve the fuel economy of the engine. Compared with the country, three car can
reduce 5% - 7% of fuel consumption. Such as a car heavy-duty diesel
vehicles (at 35 liters fuel consumption per hundred kilometers) run of 200000 km
can recover the cost of the installation of SCR system, saving cost greater than
consumption of diesel exhaust liquid processing cost.
Diesel
engine tail gas treatment liquid is the essential product to meet the four
emission standards of the country. With SCR system of heavy-duty diesel
vehicles must be charging diesel car tail gas treatment of liquid at the same
time, it is to solve the nitrogen oxides, emissions from heavy-duty diesel
exhaust governance to meet national standards for the discharge of four
essential goods.
China's
2013 release of oil standards, the requirements of the country since January 1,
2018 in full implementation of the country within the scope of the country
five. The sulfur content
of the new standard index limit value decreased from the fourth stage 50ppm to
10ppm, 80% reduction, beyond the American Standard, the main index and the
current European standards quite, to the highest international
standards. Sinopec has
respectively in 2012 to Beijing, 2013 to Shanghai and Jiangsu along the Yangtze
River City of 8, 2014 to Guangdong, Shaanxi, Zhejiang Hangjiahu area, Tianjin,
Wuhan, Hubei Province 8 a supply of provinces and cities in five
oil. In the future,
Sinopec will invest 30000000000 yuan a year to upgrade and provide more quality
resources for the community, reducing environmental pollution.
"Blue
sky environmental protection plan will be implemented 803 projects in 3 years
invested 22870000000 yuan. This is the largest environmental
protection operation in the history of the petrochemical, but so far Chinese
enterprises one-time investment in the most intensive, involving the largest
environmental protection special governance action.2014, Sinopec
has invested 11570000000 yuan, carried out 533 environmental governance
projects, accounting for 52.9% and 71.7% of the entire investment, resulting in
better social and environmental effects.
