Design of Industrial Process Refrigeration Systems
Abstract
When considering electric driven refrigeration compressors,
proper integration with the process may result in reduced power
consumption. However, the total utility situation must be
considered when evaluating the compressor driver. Conversion
from steam drivers to electric drivers may be more economical
when considering proper process integration. These questions
and various scenarios must be addressed in light of the total
process requirements and constraints.
During the last few years, Union Carbide has successfully
applied ADVENT™ technology to several complex processes that
utilize refrigeration systems. In most cases the design of a complex refrigeration system in isolation (i.e., without
considering process integration) generally results in
non-optimum refrigeration levels and excessive refrigeration
consumption. By applying ADVENT™ Process Integration
Technologv to these non-optimal designs, retrofit projects have
emerged that clearly identify how to optimize the existing
design with good project economics.
This paper presents the results of an ADVENT Process
Integration Study for the Electric Power Research Institute
(EPRI) of Palo Alto, California. The study objective was to
demonstrate process synthesis techniques for retrofit design in
two industrial refrigeration intensive processes: an olefins
process and a beer brewery process.
Study results for each retrofit design are explained along with
generalized guidelines for application to other processes. An
industry scoping portion of the study is discussed in terms of
identifying refrigeration intensive processes. Specific and
general conclusions are presented to help facilitate proper
industrial refrigeration system design throughout the industry.
