This book introduces a new and powerful approach based on rigorous
process simulations conducted with professional simulators like
HYSYS to predict the performance of supersonic separators (SS). The
book addresses the utilization of SSs for the offshore processing
of CO2-rich natural gas as an alternative to Joule-Thomson
expansion, glycol absorption, membrane permeation and chemical
absorption. It describes and analyzes the conventional offshore
processing of CO2-rich natural gas, discussing the advantages of SS
in terms of cost and power consumption. The book offers a
comprehensive framework for modeling SS units, describing the
physical principles of SS in detail. The thermodynamic multiphase
sound speed is also discussed at the light shed by a classical
analysis based on the Landau Model of phase transitions. A complete
framework is presented for modelling and simulating SS units within
HYSYS environment. A special chapter is dedicated to the
performance of SSs for removing CO2 from CO2-rich natural gas,
taking into account the limitations of CO2 freeze-out in various
scenarios of gas feed in terms of CO2 content, pressure and
temperature.
This book addresses several issues related to hydrate inhibition
and monoethylene glycol (MEG) recovery units (MRUs) in offshore
natural gas fields, from fundamentals to engineering aspects and
from energy consumption assessment to advanced topics such as
exergy analysis. The assessment of energy degradation in MRUs is
critical in offshore rigs, and the topic of exergy theory has by no
means been completely explored; it is still being developed. The
book presents a comprehensive, yet concise, formulation for exergy
flow and examines different approaches for the reference state of
MEG and definition of the reference environment so as to obtain an
effective exergy analysis with consistent results. It also provides
new and useful information that has a great potential in the field
of exergy analysis application by assessing energy degradation for
three well-known MRU technologies on offshore rigs: the Traditional
Atmospheric Distillation Process; the Full-Stream Process; and the
Slip-Stream Process. The book then elucidates how the main design
parameters impact the efficiency of MEG recovery units and offers
insights into thermodynamic efficiency based on case studies of
general distillation-based processes with sharp or not too sharp
cut, providing ranges for expected values of efficiencies and
enhancing a global comprehension of this subject. Since MEG
recovery is an energy consuming process that invariably has to be
conducted in a limited space and with limited power supply, the
book is a valuable resource for those involved in design,
engineering, economic evaluation and environmental evaluation of
topside processing on offshore platforms for natural gas
production.
