Documentation process flow diagram

WeU-written procedures should begin with a purpose and scope. The procedure section usually follows, describing the work process, and it should be clearly and concisely written. The document should include copies of all forms and a process flow diagram for illustration. 

System description is tlie compilation of tlie process/plant information needed for tlie risk analysis. For e. ample, site locations, environs, weatlier data, process flow diagrams (PFDs), piping an instnmientation diagrams (P IDs), layout drawings, operating and maintenance procedures, technology documentation, process chemistry, and tliermophysical property data may be required. 

The Process Hazards Analysis team takes a systematic approach to identify potential process hazards and to document them [51]. The Hazardous-Operation Analysis (Haz-Op) is a method by which the process procedures, process and instrument diagrams, and process flow diagrams are evaluated for operability and safety. Fault-Tree Analysis (FTA) is also a method, which investigates the assessment of what-if scenarios and failure conditions. The outcomes of this analysis are recommendations for the col-... 

This chapter covers the preparation and presentation of the process flowsheet, also known as t) t process flow diagram (PFD). The flowsheet is the key document in process design. It shows the arrangement of the equipment selected to carry out the process, the stream connections, stream flow rates and compositions, and the operating conditions. It is a diagrammatic model of the process. 

This annexure calls for comprehensive manufacturing procedures used to produce the batches of the product used to establish quality and efficacy, as also to be reflected in Annexure 16. Blank mcmufacturing documents may be submitted, however, in view of the confidentiality of these documents, memy applicants object to submitting these and rather submit the manufacturing process flow diagram and a detailed description thereof. 

To achieve this ambitious goal, the functionalities of FBW and AHEAD are synergistically combined, to offer additional benefit to the end users which cannot be provided by any of the tools. The integration itself is performed by a FBW-AHEAD integrator to link both tools. This integrator combines two master views of the design process, namely process flow diagrams as the technical master documents and the task net as the master document for developers coordination. 

AHEAD stores more coarse-grained data about design documents which are needed for management purposes. Technical process flow diagrams are represented within the product model of AHEAD as product versions which are interconnected by dependency relationships. 

Inserting a document in EVA can be accomplished while working with another engineering tool (e.g. process flow diagram tool). By retaining the option to store a document in the engineering tool it is possible to store the document in EVA, too. For this reason, the position in the structure provided by EVA and the appropriate relationship with the previous document (blue or red line, see above) must be determined. Additionally, EVA queries further information about the inserted document. 

A middle-grained model is used to declare types of documents and their dependency relations. Just the existence of these documents is declared and not their contents. For instance, the document types PFD (denoting process flow diagrams) and SimulationSpec (specifying mathematical models for process simulation) are introduced as well as the dependency relationship between them (cf. Subsect. 2.3.2). 

Based on these requirements, an early version of the integrator framework (cf. Subsect. 3.2.2) has been implemented [27, 251]. It was used to realize a first integrator tool between simulation models in Aspen Plus and process flow diagrams in Comos PT (cf. Subsect. 3.2.5). Innotec contributed the wrapper, connecting the framework to Comos PT, and evaluated early prototypes. The final prototypes of the framework and the integrator were limited in functionality and could not easily be adapted to integrate other documents. Nevertheless, they served as proof of concept for our integration approach. 

The Comos PT API is used by the Comos PT graphical user interface (GUI) to access the engineering data. The GUI provides a hierarchical overview (tree view) of the devices contained in the database for navigation, as well as detail views on devices. Different types of graphical and textual documents are provided that can contain references to devices. For instance, process flow diagrams contain references to the devices that are placed on the sheet. 

In the installation qualification (IQ) process, written evidence is given that all parts of the equipment are installed according to the equipment supplier s and purchase specifications. For complicated or large pieces of equipment, it may be decided to undertake a predelivery check of the equipment at the supplier s assembly facility. This predelivery check will also be part of the IQ. It is documented that the operating criteria for the equipment, as installed, are in compliance with the P I diagrams, plant functional specifications, and process flow diagrams. 

The IQ refers as often as possible to engineering documents (e.g., P I diagrams, plant functional specifications, process flow diagrams, inventory lists, etc.) to avoid redundant documentation and to minimize the expenditure of updating. 

Identification of Processing Equipment Requirements. When transferring processes from pilot to commercial-scale operations, a comparative analysis is usually made between the equipment used in the pilot operation with the proposed commercial facility. Process flow diagrams (PFDs) that include material balances from pilot plant experiments can facilitate this analysis. Specifications and requirements for agitation, filtration, drying, and milling devices are established based on experimental results that support these specifications and are documented. 

Flowsheets/flow diagrams are fundamental engineering documents used by everyone on a facility. The terminology used by different companies and industries varies somewhat, but the general hierarchy is from block flow diagrams (BFDs) to process flow diagrams (PFDs) to P IDs. 

Documents that will be created by the end of Phase I include process block diagrams and preliminary process flow diagrams (PFDs), and layout diagrams. 

The following tables give initial identification of hazards after study of the process flow diagrams (PFD) and basic engineering documents (BED). These tables are only for illustration purposes. 

Process flow diagram/ manufacturing floor plan This document shows the manufacturing process, including loops, operations, operators required, and locations in the factory. 

For zone classification process flow diagram (PFD), P IDs, cause and effect diagrams, area classification of plants for electrical apparatus (ref. Chapter X) and plot plans are required documents for zone classification. In process plants, different areas have different leakage or release hazards, for example, hydrocarbon storage area will have flammable gas release whereas sulfur recovery units pose a H2S toxic gas hazard. So, it is imperative to define and segregate the zones from each other.

Unfortunately, the documentation of all tempera-e cases is not always available at the preliminary ing layout stage. If this is the case, use the temper-re shown on the process flow diagrams. Typickly, design temperatures shown on pieces of equip-it are too conservative for this effort.
