debutanizer

The operation pressure of debutanizer was unstable since a light hydrocarbon recovery unit had been put into use.

某轻烃回收装置自投用以来,塔操作压力一直不稳定。

By applying multivariable model predictive control (MPC) technology, the control performance of the gasoline debutanizer of fluid catalytic cracking unit can be improved.

将多变量模型预测技术用于催化裂化汽油稳定塔，有助于提高稳定塔品质。
