PEL CAPRE adds the reassurance of validated calculation methods to the functionality and flexibility of a spreadsheet.

Calculations are an essential part of a process engineer’s job. Undetected errors in calculations can result in poor design. Errors picked up late in design result in delays or costly modifications if equipment is installed. Spreadsheets are straight forward to use but this simplicity is also a weakness as they are hard to check and it is easy to make mistakes. Once created, spreadsheets are hard to maintain and tend to evolve over time as engineers modify them. Once this happens the validity of the original calculation is compromised. PEL CAPRE provides fully documented and validated pro formas and functions with extensive unit conversion capability.

Features

• Over 30 easy to use pro forma spreadsheets addressing common engineering problems, such as fluid flow, equipment sizing and pressure-relief
• Excel functions for many process engineering equations to use in your own spreadsheets
• Built-in units conversion
• Thorough help documentation describes the use of functions and the basis of calculations
• ‘Insert function’ tool to help add individual PEL CAPRE functions to your own spreadsheets and produce your own datasheets
• Search for specific functions and make ‘favourite’ the most commonly used for easy access
• Change and create sets of units to be saved and used as default
• Includes standard PEL Tools, such as pipe inner diameter, pipe roughness, K-Value and molecular weight, to insert values directly into spreadsheets
• Provides a simple system for inserting commonly used engineering equations into Excel to allow engineers to generate their own spreadsheets and datasheets quickly and efficiently

Benefits

• Users can have complete confidence in the results
• Reduces risk of human errors in calculations - essential when working with safety critical equipment
• Allows engineers to be more efficient and productive
• Provides a documented record of calculations for audit
• Improves QA and standardises procedures by everyone using the same set of data and calculations
• PEL CAPRE can be licensed as an add-on to PEL or as a completely separate programme

PEL ADRIAN calculates flows and pressures for high velocity, compressible gases in a network and is relevant for the modelling of relief streams

PEL ADRIAN calculates single phase high velocity gas or vapour flowrates and pressure drops in piping systems. These may consist of a single pipe or a network. When supplied with the pressure at the inlets and outlet, PEL ADRIAN calculates the flows and internal pressures throughout the network. Alternatively, given the input flows and the exit pressure, it will calculate the flows and pressures at all other points.

Features

• Creating models is simple using the drag and drop toolbox and drawing surface
• Automatic pipe size correction when diameters are changed
• Table view of the system to allow quick modifications to multiple items
• Simple tools for internal pipe diameters and pipe roughness
• K Value calculator for fitting losses
• Physical property calculator through a simple interface
• Insert isometric or sketch into the drawing
• Upstream irrecoverable pressure loss due to friction and the back pressure is determined and reported as a pressure loss and a percentage of set pressure.
• Relief pressure and the exit pressure, along with the frictional losses in the pipe and across the disc can be modelled to determine the system capacity

Benefits

• Users can have complete confidence in the results
• Reduces risk of human errors in calculations - essential when working with safety critical equipment

PEL PIPER calculates the pressure, flowrate and phase of a liquid, two phase mixture, or gas along an unbranched closed conduit system using rigorous physical properties.

PEL PIPER calculates two phase flowrates and pressure drop through a pipe as well as handling single phase liquid and gas flows.

It is based on the assumption of homogeneous equilibrium flow and determines the equilibrium phase split at multiple points along the pipe to produce accurate results.

When supplied with the pressure at the inlets, PEL PIPER calculates the flow, internal pressure, temperature and vapour fraction along the pipe.

Alternatively, given the flow and the inlet pressure, it will calculate the internal pressure, temperature and vapour fraction along the pipe.

Features

• Creating models is simple using the drag and drop toolbox and drawing surface
• Automatic pipe size correction when diameters are changed
• Table view of the system to allow quick modifications to multiple items

PEL Flonet brings speed and reliability to the process of modelling liquid and low velocity gas distribution networks.

PEL Flonet calculates single phase liquid or vapour flow rates and pressure drops in piping systems. These may consist of piping loops or be ‘tree-like’ in form. Pumps and non-return valves can be included in the system. When supplied with the pressure at the inlets, PEL Flonet calculates the flows and internal pressures throughout the network. Alternatively, given the flows and one pressure, it will calculate the pressures at all other points.

PEL ProvueDB is a simple but powerful document management system with process datasheets at its heart. Installed locally or accessed on the web, your data is available when you want it wherever you are.

The proper management of process engineering data is vital. QA processes for checking and approving ensure that datasheets, calculations, reports, sketches, and other design documents are correct. Revision control for modifications and updates ensure that the most up-to-date versions are used. Information on a datasheet must be linked to the calculations and data it is based upon.

Features

PEL Logidraw is an application for drawing fault and event trees.

Fault tree analysis involves drawing a logic diagram to show the logical links between certain failure (basic) events, such as operator error or component failure, and an undesired outcome (top) event, such as an explosion at an oil storage depot.

The diagram can then be used in two ways:

1. Qualitatively - to show the combinations of basic events sufficient to cause the occurrence of the top event
2. Quantitatively - to estimate the probability or frequency of an event

PEL Logidraw helps you create fault tree diagrams by adding each of the basic failure events as a series of inputs and then linking them using AND and OR logic gates. Each input can be quantified typically as a probability or a frequency, with the output of the final gate providing a frequency for the final (undesired) outcome.

Features

• Visio based drawing tool for fault tree diagrams
• Fully automatic left to right layout
• Automatic checking of Logic validity
• Automatic input sensitivity calculation
• Copy, cut, move, and paste fault tree logic to any part of the Visio drawing. Then use the automatic ‘fix layout’ action to layout the diagram
• Copy and paste any part of the fault tree logic into Word and most other Windows applications
• Logic can be constructed on multiple pages

Benefits

• A common fault tree that maximises the involvement of others and helps develop a correct hazard analysis
• Saves time by eliminating tedious manual drawing and redrawing of fault trees as they are developed and modified
• Hazard analysis is always logically valid because Logidraw allows only logically feasible combinations of events
