【Learning Ethylene Together】Five questions per day to easily learn about ethylene 31 1. The acidic gas emission system is primarily used to collect and emit acidic gases released from devices. ( ) a. Quenching treatment b. Waste alkali treatment c. Diluted steam treatment 2. The maximum emission volume of the flare can be determined by considering the total amount of gas at the top of the quench tower during an emergency situation. ( ) a、Total emissions from the ethylene compressor b、Total emissions from the propylene compressor c、Total emissions from the pyrolysis gas compressor. 3、The flow rate of materials in the low-temperature system should not be too high; this can cause problems, especially when there is water in the flare tanks and pipelines. ( ) a. Liquid blockage b. Freeze blockage c. Difficulty in oil-water separation 4. It is strictly prohibited to accidentally discharge anything into the flare system of the ethylene plant. ( ) a、Process nitrogen b、Process air c、Process oxygen. 5. When increasing the equivalent weight and other parameters does not result in hydrogenated products that meet the specifications, the hydrogenation reaction catalyst should be regenerated. ( ) a. Outlet temperature or hydrogen-acetylene ratio b. Inlet temperature or acetylene-hydrogen ratio c. Inlet temperature or hydrogen-acetylene ratio 1. The acidic gas emission system is primarily used to collect and emit the acidic gases generated in the equipment. (b) a. Quenching treatment; b. Waste alkali treatment; c. Diluted steam treatment. 2. The maximum emission volume from the flare can be determined by considering the total amount of gas at the top of the quench tower during an emergency situation. (c) a. Total emissions from the ethylene compressor; b. Total emissions from the propylene compressor; c. Total emissions from the pyrolysis gas compressor. 3. The flow rate of materials in the low-temperature system should not be too high, especially when there is water present in the flare tanks and pipelines, as this can cause problems. (b) a. Liquid blockage b. Frozen blockage c. Difficulty in separating oil from water. 4. It is absolutely forbidden to mistakenly discharge substances into the flare system of the ethylene plant. (b) a. Process nitrogen b. Process air c. Process oxygen. 5. When increasing the equivalent weight and other parameters does not result in hydrogenated products that meet the specifications, the hydrogenation reaction catalyst should be regenerated. (c) a. Exit temperature or hydrogen-acetylene ratio b. Inlet temperature or acetylene-hydrogen ratio c. Inlet temperature or hydrogen-acetylene ratio
