Based on the independently designed amine deacidification experimental device
the experiment adopted the common-used oxyamine process and preliminary preferred amine formulation (2 mol·L-1+1 mol·L-1) to study the optimization of operating parameters of alcohol amine gas decarbonization.The result are will be used to guide the industrial production.This paper analyzed the influence of the operating parameters on the amine decarbonization process under the control variable method with 6% and 4% CO2 content and get the optimizing operating parameter.The results show that: the increase of the absorption temperature
the absorption pressure
and the amine solution circulation flow can improve amine absorption performance
the increase of the performance.However
all the parameters are influenced by the reaction mechanism
vapor-liquid equilibrium
the energy consumption
the nature of the amine solution and other factors
there is an optimal value; Under this experimental system
when the raw gas processing capacity is 50 Nm3·h -1
The optimization results of operating parameters are as follows: the absorption temperature is 55℃
the absorption pressure is 3.5-4 MPa
the amine solution circulation flow is 0.25 m3·h-1
the regeneration temperature is 120℃ and the regeneration pressure is 50 kPa.
