Under certain conditions, the conversion rate when the reaction reaches chemical equilibrium is called ( ). 38. When NH3/CO2 is greater than ( ), it is not economically viable from a technical standpoint. 39. The CO2 used in urea production comes from the ammonia synthesis plants ( ). 37. Under certain conditions, the conversion rate at which the reaction reaches chemical equilibrium is called the (equilibrium conversion rate). 38. When the NH3/CO2 ratio is greater than (4.5), it is not economically viable from a technical standpoint. 39. The CO2 used in urea production is all derived from the ammonia synthesis plant (decarbonization gas).
37. Equilibrium conversion rate 38. 4.5 39. Decarburization gas
37. Under certain conditions, the conversion rate at which a reaction reaches chemical equilibrium is called the (equilibrium conversion rate). 38. When NH3/CO2 is greater than (4.5), it is not economically viable from a technical standpoint. 39. The CO2 used in urea production is all derived from the ammonia synthesis plant (decarbonization gas).
37. Under certain conditions, the conversion rate at which the reaction reaches chemical equilibrium is referred to as the (maximum conversion rate). 38. When NH3/CO2 is greater than (4), it is not economically viable from a technical standpoint. 39. The CO2 used in urea production comes from the ammonia synthesis plant (generated as a result of the regeneration of the decarboxylation solvent in the decarboxylation unit).
37. Under certain conditions, the conversion rate at which a reaction reaches chemical equilibrium is called the (equilibrium conversion rate). 38. When NH3/CO2 is greater than (4.5), it is not economically viable from a technical standpoint. 39. The CO2 used in urea production is all derived from the ammonia synthesis plant (decarbonization gas).
37. Under certain conditions, the conversion rate at which a reaction reaches chemical equilibrium is called the (equilibrium conversion rate). 38. When NH3/CO2 is greater than (4.0), it is not economically viable from a technical standpoint. 39. The CO2 used in urea production is all sourced from ammonia synthesis plants (the carbon dioxide gas removed by the decarburization unit serves as the raw material).
37. Equilibrium conversion rate 38.4.5 39. Decarburization gas
37. Under certain conditions, the conversion rate at which a reaction reaches chemical equilibrium is known as the (equilibrium conversion rate). 38. When NH3/CO2 is greater than (4.5), it is not economically viable from a technical standpoint. 39. The CO2 used in urea production is all derived from the ammonia synthesis plant (decarbonization gas).
Equilibrium conversion rate: 4.5, decarburized gas
37. Equilibrium conversion rate 38. 4.5 39. Decarburization gas
Equilibrium conversion rate: 4.5, decarburized gas
