CONTROL AND ENERGY SAVINGS OF THE PETLYUK DISTILLATION SYSTEM

Control Properties of Alternative Schemes to The Petlyuk Distillation Configuration

The Petlyuk distillation system has received considerable attention because of the reported energy savings with respect to conventional sequences. The lack of widespread use of the Petlyuk system has been mainly attributed to potential control problems. Some of the control challenges result from the transfer of vapor streams back and forth between the columns. This means that neither of the two...

Optimizing Control of Petlyuk Distillation: Understanding the Steady-State Behavior

The "Petlyuk" or "dividing-wall" or "fully thermally coupled" distillation column is an interesting alternative to the conventional cascaded binary columns for separation of multi-component mixtures. The industrial use has been very limited, and difficulties in control has been reported as one reason. Since we have more manipulated variables than controlled variables, the column is a candidate ...

Multicomponent Distillation Configurations with Large Energy Savings

In industry, many separation processes involve the separation of multicomponent mixtures using distillation. There are many distillation configurations that can carry out the same overall separation process. These configurations use an equal number of distillation columns, but they differ significantly in energy consumption. Therefore a major challenge for a practitioner is the identification o...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
