Three flare systems are modeled and total plant depressurization is investigated using dynamic simulations in order to access the debottlenecking potential. Usually, steady-state simulation of the flare network is used for sizing and rating of the flare system. By using dynamic simulations, effects from line packing in the flare system can be studied. The results show that peak flow during a dynamic simulations is significantly lower than the peak flow used in a steady-state case. The three systems investigated span a wide range in flare system size, both in terms of number of process segments disposing into the flare network, in terms of peak design rate, the flare network pipe dimensions and total hold-up volume. Generally, it is observed that the larger the flare system, the larger debottlenecking potential.

对三个火炬系统进行了建模，并使用动态模拟研究了整个植物的降压效果，以获取消除瓶颈的潜力。通常，火炬网络的稳态仿真用于火炬系统的大小和评级。通过使用动态仿真，可以研究火炬系统中管线堆积的影响。结果表明，动态仿真过程中的峰值流量显着低于稳态情况下使用的峰值流量。所研究的三个系统的火炬系统尺寸范围很广，包括布置在火炬网络中的工艺段数量，峰值设计速率，火炬网络管道尺寸和总滞留量。通常，观察到火炬系统越大，消除瓶颈的可能性越大。
