Services

Features and objectives:

Develop process flow diagrams/schematics suitable to support the review
Identify and quantify process & utility heating and cooling duties — amount and temperature
Develop heat and material balances/simulation models if appropriate
Pinch analysis if appropriate - data extraction, composite curves, heat exchanger network analysis, thermal utility targets, scope for heat recovery, CHP and process modifications
Identify theoretical and practical scope for additional heat recovery
Identify practical projects for heat (& water) recovery, CHP and improved thermal utilities
Preliminary conceptual design

Schematic flow diagrams if not previously available in suitable form
Heat and material balances and other models if relevant
Quantified scope for energy savings
Key features/process design concepts which materially influence the opportunities for savings
Conceptual design/feasibility study of retrofit projects - water and energy savings
Optimum heat recovery and water use/reuse configurations — new plant/major expansions
Optimum thermal utility configurations
Conceptual design of optimum CHP
Recommended ongoing strategy to reduce carbon emissions by improved energy integration

Typical PI investigations identify some low cost projects suitable for implementation with minimal further investigation
Other projects may require detailed technical and economic feasibility studies and in some cases need to be optimised when further data have been obtained or decisions taken after completion of the initial PI review
Maximum value is obtained from PI when the analysis is kept up to date in line with ongoing changes on the site
In particular any future process developments should be reviewed in advance from a PI perspective to ensure that further opportunities for efficiency are not missed
