【Learn Ethylene Together】Five questions per day to easily learn about ethylene 05 26. The reaction equation for cleaning coke with pure steam is ( ). 27. In recent years, ethylene-producing countries have generally adopted new processes and technologies to modify and expand existing facilities, with the aim of improving ( ), increasing production capacity, expanding the sources of raw materials, and reducing ( ) and ( ). 28. To evaluate the quality of a cracking feedstock, one must consider the ( ) of target products such as ethylene and propylene, and the operating ( ) of the cracking furnace. The yield of ethylene, propylene, etc. ( ), and the furnace operation cycle ( ), the better the cracking performance of this feedstock. 29. The function of continuous blowdown from the steam drum of the cracking furnace is ( ). 30. The basic parameters of a valve are ( ), ( ), ( ). 26. The reaction equation for cleaning coke with pure steam is ( ). C＋H2O→CO＋H2 –Q 27. In recent years, ethylene-producing countries have widely adopted new processes and technologies to modify and expand existing facilities, with the aim of improving ( ), increasing production capacity, expanding the range of available raw materials, and reducing ( ) and ( ). Ethylene yield, flexibility, material consumption, energy consumption. 28. To evaluate the quality of a cracking feedstock, it is necessary to consider the ( ) of target products such as ethylene and propylene, as well as the operating ( ) of the cracking furnace. The yield of ethylene, propylene, etc. ( ), and the furnace operation cycle ( ), the better the cracking performance of this feedstock. The higher the yield cycle, the longer it is. 29. What is the function of continuous drainage from the steam drum of the pyrolysis furnace? Ensure the quality of the boiler water and prevent the accumulation of harmful substances. 30. The basic parameters of a valve are ( ), ( ), ( ). Nominal diameter Nominal pressure Applicable medium
