【発明の名称】統合されたガス化制御のためのシステム
Document Type and Number:
Japanese Patent JP2002524653
Kind Code:
A
Abstract:
An integrated control system (ICS) for a gasification plant controls the operation of a gasifier and other critical components of the gasification plant. The ICS improves the performance of a gasification plant by controlling the operation of a gasifier and other critical components by an integrated controller, rather than by several independent controllers. The ICS is a sub-system of a larger distributed control system that controls the operation of the gasification plant. The ICS controls the following: (i) oxygen to carbon (O/C) ratio in a gasifier; (ii) syngas demand or the desired output of a gasifier; (iii) load constraints; (iv) moderator flow into a gasifier; (v) air separation unit (ASU); (vi) oxygen header vent valves; and (vii) syngas header pressure.
