SOFTWARE
- Expander/Compressor Off-Design Utility (EC-ODTM) for Aspen HYSYS®
More
Info
Mafi-Trench
and River City Engineering have developed new
software used to predict turboexpander off-design performance in plant simulations.
EC-OD is a unit operation extension designed to rigorously calculate expander
compressor off-design performance within Aspen HYSYS. For more information about EC-OD please contact
marketing@mafi-trench.com
or
kpennybaker@rivercityeng.com.
- CO2 Freeze Utility for Aspen HYSYS®
More
Info
The utility integrates with
Aspen HYSYS and aids in the evaluation of CO2 freeze potential
for natural gas processing plants. It predicts both
vapor and liquid phase CO2
freezing temperatures for process streams, heat
exchangers, expanders, and columns.

Errors discoverd to
date in the article "Calculation of Two-Phase
Pressure Drop":
1. Eqn 42 should read (1-xg)^2 + xg^2..., not
(1-xg)^2 x xg^2
2. Eqn 45 is missing gc in the denominator
(i.e. gc x pliquid x d)
