Projects and Industrial Sites need to calculate site-wide balances for steam, fuel gas, and now greenhouse gas emissions. Typically, these calculations are performed by specialized engineers using separate tools, then manually integrated together sometimes without ever fully closing the overall balance. With AVEVA Process Simulation, a single integrated simulation that simultaneously calculates all steam, fuel gas, and greenhouse gas emissions balances in seconds can be achieved. With a valid, fully closed balance, engineers can support design, operating, and planning decisions to improve the efficiency, reliability, and sustainability to support Project and Industrial Site needs.
