1. What is the Plant Design System?

Intergraph’s plant design software can be used to design any type of plant—from petrochemical plants, offshore platforms, chemical and pharmaceutical plants, consumer products (food, beverages, cosmetics, soap, paper, and so forth), to power plants, waste water treatment plants, and cogeneration facilities.Specifically, the Plant Design System (PDS) integrates many discipline-specific software modules; these modules automate the many phases of a plant design project. Instrument Data Manager is one of these modules. Designing a plant with the modular Intergraph-Zydex plant design software system comprises four phases:

1. Project Setup - 2D and 3D design files, project files, databases.
2. Preliminary Design - feasibility studies, cost estimates, general layouts and process flow diagrams.
3. Detailed Design - process, instrumentation, piping layouts, material control.
4. Design Review - 3D model walk-through.

1.1 What are the 2D modules?

PDS 2D is used to create schematic diagrams and to provide the associated reports and MTOs, and to define and purchase all equipment, instruments, pipe, and so forth, necessary to build the plant. All of the needed data is stored in databases. These are relational databases which you can query, add, delete, or edit information to suit your own or your client’s needs.
The PDS 2D modules are briefly discussed in the following sections.

1.1.1 Process Flow Diagram (PFD)


Conceptual design of a plant includes feasibility studies, cost estimates, and process simulations. Third-party process simulation packages such as ASPEN or SimSci allow engineers to perform preliminary calculations such as chemical equilibriums, reactions, heat and material balances and/or design pressures and temperatures. The data produced from these calculations are transferred to PDS where a process flow diagram (PFD) is developed.

1.2 What are the 3D modules?
PDS 3D is used to create three-dimensional plant models, create equipment models, extract isometric drawings, and perform design interference checks and equipment clashes. As with the 2D modules, all of the needed data is stored in relational databases which can be queried or edited. The PDS 3D modules are briefly discussed in the following sections.

1.2.1 Equipment Modeling (PD_EQP)
Equipment Modeling (PD_EQP) allows designers to model the equipment defined in the P&ID.
Stylistic representations of equipment items are produced, with or without nozzles, by entering data from equipment data sheets noting dimensions and weights. Upon completion, the equipment item is placed in the 3D model. Within PD_EQP, designers can create a physical envelope defining the space occupied by an equipment item along with space envelopes defining maintenance and access areas. This process is instrumental for interference checking later in the modeling process.
