Learning Objectives Once you have completed this module you will be able to Specify and attach head and efficiency curves to compressors Use single and multiple curves to model compressors Attach head curves to pumps Accurately model existing plant equipment with HYSYS Prerequisites Before beginning this module you should have a reasonable understanding of the HYSYS program and be familiar with adding and basic configuration of Pumps and Compressors. 2 Compressor and Pump Curves 3 Don t worry if you haven t built the case mentioned. The ADV6_AdvancedRecycles_ file contains this case. Compressor Curves Using compressor curves in your HYSYS simulation allows you to accurately model existing plant equipment. You can determine if an existing compressor is able to meet the specifications of your process. Using compressor curves allows HYSYS to calculate heads and efficiencies that are dependant on the flow rate. If the flow rate through the compressor is known to be constant a single pressure rise and efficiency can be supplied. If however the flow rate is expected to change using a compressor curve will allow HYSYS to calculate new heads and efficiencies based on the current flow rate. This results in greater accuracy in the simulation and allows HYSYS to more closely model actual plant equipment. Workshop In this workshop you will add a set of multiple curves to the K-stage 2 compressor in the Advanced Recycle Module simulation. 1.
