ACCE V8.7.1 increases estimate accuracy with the
2014 Cost Basis Update. In addition to the annual update, users can now: scale
projects by area; utilize a new way of estimating electrical substations,
including the ability to specify multiple substations on the same form, such
as cascading transformers; and estimate piping using a weight basis.
There are also new models for estimating multi
stream plate fin exchangers, venturi, and cyclone scrubbers.
Aspen DMC3 software provides a simple tuning factor to
set the degree of LP robustness to prevent LP
flipping by avoiding the use of weak process handles to deal
with new CV limit excursions.
Using process knowledge improves model fidelity
and reduces the likelihood of erroneous gains. Aspen DMC3 software makes it easy to preserve
the structure of the control model by imposing real-world constraints on model
Relief device design and rating is now available in Aspen Plus, in addition to Aspen HYSYS! Ensure that
proper relief valve and rupture disk sizing methods are used throughout analysis. Use accepted industry-standard API 520, 521, and 2000 to calculate necessary valve and rupture disk sizing specifications. Additional new
features in both simulators include new fire scenario calculations, storage
tank protection, and multivalve analysis.
Aspen Capital Cost Estimator (ACCE)
V8.6 extends into detailed estimating with the ability to create more precise
estimates. With a new Unit Rate Excel spreadsheet import/export option, you can
overwrite ACCE generated values for material unit rates and unit man hours, as
well as define custom materials of construction. Take advantage of this new
functionality to increase estimate precision, reduce estimate uncertainty, and
speed up estimate reviews.
modeling capabilities were introduced with V8.0, and have continually been
upgraded with subsequent releases, V8.2 and V8.4. In V8.6, a new contact dryer
model and enhanced indirect drying in the convective dryer model were
introduced as well as enhanced particle size definition in the reactor models.
