tailieunhanh - Depressurisation: A Practical Guide

Tại sao có hai tùy chọn tiện ích Depressuring? Depressuring gốc tiện ích trong HYSYS là một tính toán giả năng động dựa trên một loạt các tính toán trạng thái ổn định. Các tiện ích Depressuring động đã được giới thiệu trong HYSYS cho phép người dùng thực hiện các tính toán phụ thuộc vào thời gian thích hợp. Giấy phép HYSYS Dynamics là không cần thiết để sử dụng tiện ích mới. Tiện ích này có thể được sử dụng cho? Tiện ích Depressuring có thể được sử dụng để mô phỏng depressurisation khí, khí lỏng đầy. | HYPRCTECH lK L IFECYCLE INNOVATION This guide has been prepared based upon questions frequently asked regarding the Dynamic Depressuring utility introduced in HYSYS . It should provide users with an explanation how to use the utility and correctly interpret the results. It is divided into three sections Overview Adding and Configuring the Utility Example Problem Overview Why are there two Depressuring utility options The original Depressuring utility in HYSYS was a pseudo-dynamic calculation based on a series of steady state calculations. The Dynamic Depressuring utility was introduced in HYSYS to allow users to perform proper time-dependant calculations. A HYSYS Dynamics licence is NOT required to use this new utility. What can this utility be used for The Depressuring utility can be used to simulate the depressurisation of gas gas-liquid filled vessels pipelines and systems with several connected vessels or piping volumes depressuring through a single valve. References to vessel in this guide can also refer to piping or combinations of the two. What types of depressuring calculations can be performed There are two major types of depressuring calculations available Fire Mode is used to model a vessel or pipe under fire conditions. This mode has three sub-types Fire Fire Wetted and Alternative Fire. Adiabatic Mode is used to model the blowdown of pressure vessels or piping with no external heat supplied. A more in depth discussion of the different methods follows in Section . Adding and Configuring the Utility How to add the utility A Depressuring utility can be added to the case by selecting Tools Utilities highlighting Depressuring - Dynamics and pressing the Add Utility Button. You may note that the original Depressuring model is still shown on the Available Utilities menu this option will be discontinued after version and all existing models will be converted to the new Dynamic utility.
