Starting emission reduction method for ethene device
ActiveCN104152173AShorten cooling timeEmission reductionThermal non-catalytic crackingEthylene productionRefluxGas compressor
The invention relates to a starting emission reduction method for an ethene device. The method comprises the following steps: first, an ethene and propylene refrigeration system is started and a refrigerating capacity is supplemented for cold box precooling; second, the cold box precooling is started; third, total reflux of an ethene rectifying tower, a propylene rectifying tower and an ethane removing tower is established; fourth, a cracking furnace is started; fifth, a cracked gas compressor is started; sixth, a subsequent device is started and starting of the ethene device is finished. Because the cold box is subjected to cooling before formal feeding, the product qualified time of the cold box is shortened greatly, the cooling process of the cold box is controllable, and leakage dangers are avoided. Through establishment of total reflux of a low-temperature depropanization tower, the total qualified time of a high-low-pressure depropanization tower is shortened. Because natural gases are introduced to supplement the feed of the compressor, the number of starting feeding cracking furnaces is decreased, and therefore the whole discharge capacity of torches is reduced.

The invention relates to a starting emission reduction method for an ethene device. The method comprises the following steps: first, an ethene and propylene refrigeration system is started and a refrigerating capacity is supplemented for cold box precooling; second, the cold box precooling is started; third, total reflux of an ethene rectifying tower, a propylene rectifying tower and an ethane removing tower is established; fourth, a cracking furnace is started; fifth, a cracked gas compressor is started; sixth, a subsequent device is started and starting of the ethene device is finished. Because the cold box is subjected to cooling before formal feeding, the product qualified time of the cold box is shortened greatly, the cooling process of the cold box is controllable, and leakage dangers are avoided. Through establishment of total reflux of a low-temperature depropanization tower, the total qualified time of a high-low-pressure depropanization tower is shortened. Because natural gases are introduced to supplement the feed of the compressor, the number of starting feeding cracking furnaces is decreased, and therefore the whole discharge capacity of torches is reduced.
