MANUAL ON INSTALLATION OF REFINERY INSTRUMENTS AND CONTROL SYSTEMS PART I-PROCESS INSTRUMENTATION AND CONTROL SECTION 12-INSTRUMENT PANELS (SECOND EDITION)
PREFACE This section is one of a series which make up RP 550@ Manual on Installation of Refinery Instruments and Control Systems. RP 550 is composed of four parts: Part I -Process Instrumentation and Control Part II -Process Stream Analyzers Part III-Fired Heaters and Inert Gas Generators Part IV-Stream Generators Part I assays the installation of the more commonly used measuring and control instruments@ as well as protective devices and related accessories; Part II presents a detailed discussion of process stream analyzers; Part III covers installation requirements for instruments for fired heaters and inert gas generators; and Part IV covers installation requirements for instruments for steam generators. These discussions are supported by detailed information and illustrations to facilitate application of the recommendations. The format of RP 550@ Part I has been changed to facilitate continuity of presentation@ convenience of reference@ and flexibility of revision. Each section is now being published individually as follows: Section 1-Flow Section 2-Level Section 3-Temperature Section 4-Pressure Section 5-Automatic Controllers Section 6-Control Valves and Positioners Section 7-Transmission Systems Section 8-Seals@ Purges@ and Winterizing Section 9-Air Supply Systems Section 10-Hydraulic Systems Section 11-Electrical Power Supply Section 12-Control Centers Section 13-Alarms and Protective Devices In the preparation of these documents@ it was necessary to decide on a logical method of presentation: should each point be explained as fully as possible@ or should extensive cross-referencing be done between sections? The final documents contain a combination of these methods of presentation. An attempt has been made to make each section as complete as possible@ with cross-referencing done only where very extensive repetition would have been required. Users of this recommended practice are cautioned to obtain a complete set of sections in order to efficiently accomplish any cross-referencing that is required for a full understanding of the subject matter.
