Natural gas industrial parks are composed of raw natural gas refining plants, urea plants
and power plants. The processes of natural gas refining and utilization in industrial parks are …

Extractive distillation (ED) processes are widely used for the separation of aromatic and non-
aromatic hydrocarbons. Approximate boiling points of components and azeotropes in the …

A chemical or petrochemical site is generally made up of several plants that are linked
together through process streams. The linking process streams are often cooled down in …

We propose a mixed-integer nonlinear programming (MINLP) model for simultaneous
chemical process and heat exchanger network synthesis. The model allows process stream …

问题, 常见于工业系统中的热交换网络和质量交换网络, 水网以及其他网络 …

Research and application of superstructure can effectively solve the problem of energy
efficiency in the fields of chemical industry, water treatment, steel, metallurgy and so on, and …

We propose optimization-based approaches for heat integration and distillation network
synthesis. For heat integration, we propose a mixed-integer nonlinear programming (MINLP) …

In this work, a novel graphical method is presented to quantitatively identify the optimal feed
stage locations of double-feed columns on the basis of the column grand composite curve …

An absorption and stabilization system is an important process, which is used to produce the
industrial raw materials such as dry gas, liquefied petroleum gas, and stable gasoline …
