1 overview of construction projects
Project Name: annual output of 500 thousand tons of two tons of dimethyl ether project;
Construction unit: Anhui Haoyuan Chemical Industry Group Co. ltd.;
Project nature: new;
Project construction site: Fuyang coal based new material industry park;
Project construction content and scale: 500 thousand tons / year two methyl ether, 33375 tons / year of sulfuric acid, 250 million Nm3/ liquid nitrogen, 20 million Nm3/ liquid argon. The new 1 sets an annual output of 500 thousand tons of two ether production device, including gasification device, conversion device, low temperature methanol washing system, methanol synthesis unit, methanol distillation device, two ether device and supporting the coal storage and transportation, air separation system, sulfur recovery unit, auxiliary tank engineering.
2 environmental impact analysis and pollution control measures
2.1 waste gas
The project part of the proposed process of waste gas into the torch system combustion process, other exhaust emissions by high altitude exhaust. The boiler adopts the "electric bag compound dust collector" and the "ammonia method desulfurization +SNCR".
2.2 waste water
Wastewater and domestic sewage are mainly contained in the proposed project. The production of wastewater containing gasification slag water treatment system of wastewater, sewage, waste heat boiler transformation, low temperature methanol washing sewage and methanol distillation wastewater, the wastewater and sewage treatment standards by the station into the Park recycling plant self built sewage treatment plant.
2.3 noise
The project is the main noise source of two ether reactor, all kinds of pumps, the mechanical noise value between 90 ~ 110dB (A), sound insulation, shock absorption of plant to take measures to reduce the noise.
2.4 solid waste
From the project in the production process are mainly gasification furnace ash and boiler slag, waste catalyst etc.. The gasification furnace ash and boiler slag disposal and comprehensive utilization; waste catalyst waste molecular sieve for dangerous solid waste, by analysing the temporary evacuation of qualified units of sludge treatment; sewage treatment station annual clean-up after the filter press Sinotrans landfill. Garbage removal unified by the local sanitation department.
3 measures to prevent or mitigate adverse environmental impacts
3.1 waste gas
(1) coal powder gasification separation bag filter exhaust, air separation system, exhaust gas Rectisol hydrogen sulfide concentration tower and CO2 stripper gas, sulfur recovery tail gas through the exhaust tube discharge in the sky.
(2) gasification, flash steam gasification furnace exhaust gas, transform the open parking tower condensate separation gas, methanol synthesis gas separator and bentonite gas and methanol distillation tower pre noncondensable gas into the flare system processing.
(2) boiler waste gas by using coal as fuel, combustion tail gas using "electric bag composite dust collector + ammonia desulfurization +SNCR" measures after the exhaust gas exhaust.
3.2 waste water
The production of wastewater containing gasification slag water treatment system of wastewater, sewage, waste heat boiler transformation, low temperature methanol washing sewage and methanol distillation wastewater, the wastewater and sewage treatment standards by the station into the Park recycling plant self built sewage treatment plant.
3.3 solid waste
From the project in the production process are mainly gasification furnace ash and boiler slag, waste catalyst etc.. The gasification furnace ash and boiler slag disposal and comprehensive utilization; waste catalyst waste molecular sieve for dangerous solid waste, by analysing the temporary evacuation of qualified units of sludge treatment; sewage treatment station annual clean-up after the filter press Sinotrans landfill. Garbage removal unified by the local sanitation department.
3.4 noise control measures
Technical transformation project for some high intensity noise source using appropriate noise reduction, noise reduction measures to minimize the impact of noise on the environment.
(1) selection of high quality, low noise fan and water pump;
(2) in order to make the equipment with high noise, the equipment manufacturers are required to use low noise equipment;
(3) source of noise isolation components, reduce solid voice;
(4) as far as possible to the noise source and sound insulation measures, such as setting the sound insulation cover, at the same time consider the reasonable ventilation cooling.

4 conclusions of environmental impact assessment
Overall, Anhui Haoyuan chemical industry group limited two annual output of 500 thousand tons of dimethyl ether project in line with national industrial policy, the project site to meet the local development and environmental planning requirements. The project adopts domestic advanced production technology, in accordance with the requirements of clean production, with complete waste water, waste gas purification facilities, waste water, waste gas emissions to meet the relevant standards of the state. To sum up, as long as the pollution control measures in the construction of the project construction units in the EIA report carried out, to ensure that all kinds of pollutant discharge standards, from the point of view of environmental impact, this project is feasible.
