Definitions
- the present invention relates to a method for producing acrolein and / or acrylic acid, and more particularly, to producing acrolein and / or acrylic acid by vapor-phase oxidation of pyrene or propane with an oxygen-containing gas in the presence of an oxidation catalyst. Suspended particles as oxygen source
- the performance of the catalyst can be reduced by coking, etc.
- the present invention relates to a method for producing acrolein and / or acrylic acid stably for a long time in a high yield without any loss.
- acrolein and acrylic acid by catalytic gas-phase oxidation of propylene or propane with an oxygen-containing gas is widely industrially performed.
- propylene is subjected to gas-phase oxidation of propylene with an oxygen-containing gas to produce mainly acrolein, and a two-stage reaction consisting of a subsequent step of further oxidizing the reaction gas containing acrolein to produce acrylic acid. Acid is produced.
- the daily average value of "1-hour value is there in 0. 1 0 mg / m 3 or less
- the hourly value must be less than 0.2 Omg Zin 3 '', but this suspended particulate matter is found to be contained in a considerable amount in factory smoke and diesel car exhaust. This value is known, especially in the vicinity of roads with heavy traffic, etc., and this value often exceeds this value.
- the number of days that exceeded this value in Ota Ward, Tokyo was one year In some places, it is close to 100 days.
- the Japan International Cooperation Agency's report on the improvement of environmental information by country in October 1997 showed that, for example, in China, air pollution was serious in urban areas, and airborne particulate matter in each city was serious.
- the concentration exceeds the environmental standard, and the city Is the annual average value of 7 9 ⁇ 6 l 8 g Zm 3 in ⁇ , and has become a average 3 0 9 ⁇ g Zm 3 of the urban areas of the country, particularly described that the city of the north has become a high value Have been.
- the concentration of suspended dust in the six major cities of Bombay, Kakatsuta, Delhi, Ahmedabad, Limpumbur and Nagpur exceeds three times the average value of the WHO annually, resulting in serious air pollution. It is described that it is. It is said that the amount of suspended particulate matter in the atmosphere is extremely large, and various concerns about environmental pollution are increasing worldwide. However, there is a large gap in the concentration of suspended particulate matter in the atmosphere due to adjacent facilities.
- the present inventors proceeded to investigate the cause of the difference in the degree of increase in the differential pressure of the reaction tube and the difference in the time until blockage depending on the location of the factory, and found that the location of the manufacturing facility was There is a difference in the status of air pollution, especially in the amount of impurities such as suspended particulate matter in the air.In places with severe pollution, the time required to close the reaction tube tends to be shorter, i.e., in the air. We found that caulking of the catalyst by particulate matter was not negligible.
- a filter with a fine aperture of, for example, 10 / m or less is installed at the inlet of the compressor for introducing air into the inlet of the compressor, together with a coarse mesh that is usually used to remove large debris.
- the inventors have found that removal of impurities such as suspended particulate matter significantly reduces the pressure difference and blockage of the reaction tube, and has completed the present invention.
- the present invention in a method for producing acrolein and / or acrylic acid by subjecting propylene to gas-phase oxidation with an oxygen-containing gas in the presence of an oxidation catalyst, provides a method for producing acrolein and / or acrylic acid, wherein air is used to remove suspended particulate matter.
- the air from which suspended particulate matter has been removed is used as an oxygen source. It is characterized by the following.
- the method of removing suspended particulate matter from the atmosphere is not necessarily limited.
- a method of installing a filter at the inlet of a compressor for introducing into the atmosphere a method of passing water through before introducing the reaction tube
- a method using the atmosphere through an electric dust collector In the method of passing through water, the air after passing through the water bath contains water droplets or excess moisture. Since the water droplets contain the suspended particulate matter that has been removed, they are again introduced into the reaction tube. Excess moisture will increase the amount of gas introduced into the compressor.
- the method of passing through an electric dust collector costs much to install, maintain, and manage the electric dust collector. Therefore, the most economical and effective method for removing suspended particulate matter from the atmosphere is to install a filter at the inlet of a compressor for air introduction.
- the fineness (opening) of the above filter is not necessarily limited, and can be determined as appropriate according to the particle size and concentration of suspended particulate matter at a factory location.
- a filter with different openings is installed in the inlet of the compressor in advance, and the amount of suspended particulate matter present in the air after passing through the filter is, for example, the daily average of the hourly value, which is the environmental standard in this book.
- a preferred filter aperture is, for example, 10 xm or less, since the suspended particulate matter is usually particles of 10 zm or less.
- Determining when to replace the filter is not necessarily limited. For example, a method of constantly measuring and monitoring the weight increase of the filter and replacing the filter when the filter reaches a predetermined value can be suitably adopted. If the filter clogs too quickly with one type of filter, one method is to provide a combination of filters with different openings.
- the weight increase of the filter can be measured by, for example, a load cell. Also, the value of the weight increase of the filter, which is a guide for the filter replacement time, can be obtained in advance by experiments.
- the filter differential pressure may be constantly measured and monitored, and the filter may be replaced when the specified value is reached.
- a pressure gauge is installed on the inlet side and the outlet side of the gas (for example, air) flowing into the filter, and the difference is used as a differential pressure.
- the value of the differential pressure which is a guide for the filter replacement time, can be obtained in advance by experiments.
- filters there is no particular limitation on the number of filters to be installed.However, if air filters are frequently replaced due to severe air pollution, or if it is necessary to continue the operation of the device after the filter replacement period, etc. You may install two or more in parallel. Also, a filter cleaning device may be provided.
- Impurities such as nitrogen, carbon dioxide, NO x, SO x, and moisture contained in the atmosphere do not particularly affect this reaction as long as they are in the amount range normally contained in the atmosphere.
