Heat Pumps In Chemical Process Industry

As the chemical process industry is among the most energy demanding sectors, chemical engineers are endeavoring to contribute towards sustainable future. Due to the limitation of fossil fuels, the need for energy independence, as well as the environmental problem of the greenhouse gas effect, there is a large increasing interest in the research and development of chemical processes that require less capital investment and reduced operating costs and lead to high eco-efficiency. The use of heat pumps is a hot topic due to many advantages, such as low energy requirements as well as an increasing number of industrial applications. Therefore, in the current book, authors are focusing on use of heat pumps in the chemical industry, providing an overview of heat pump technology as applied in the chemical process industry, covering both theoretical and practical aspects: working principle, applied thermodynamics, theoretical background, numerical examples and case studies, as well as practical applications. The worked-out examples have been included to instruct students, engineers and process designers about how to design various heat pumps used in the industry. Reader friendly resources namely relevant equations, diagrams, figures and references that reflect the current and upcoming heat pump technologies, will be of great help to all readers from the chemical and petrochemical industry, biorefineries and other related areas.

Heat pumps and related technology are in widespread use in industrial processes and installations. This book presents a unified, comprehensive and systematic treatment of the design and operation of both compression and sorption heat pumps. Heat pump thermodynamics, the choice of working fluid and the characteristics of low temperature heat sources and their application to heat pumps are covered in detail. Economic aspects are discussed and the extensive use of the exergy concept in evaluating performance of heat pumps is a unique feature of the book. The thermodynamic and chemical properties of certain new working fluids and sorbents are also explored. There are considerable pressures on those involved in the use of heat pumps to achieve energy savings and this presents a challenging task in today's industrial climate. This book provides many examples of such energy savings such as the use of large heat pump units utilising various low temperature industrial waste heat sources. Heat Pumps is illustrated throughout by specific solutions as applied worldwide. The subject area is approached logically, covering both design and calculation methods, and is oriented towards the needs of the process user. The treatment given to the selection of working fluids should be compulsory reading. - Chemical Engineer, June 1994

This book explores sustainability engineering through the lens of the manufacturing and chemical process industries to elucidate the safe and economic implementation of process designs used to transform raw materials into useful finished products. The author applies the tenets of sustainability science to develop an engineering methodology that supports the perpetual availability of raw materials through recycling/reuse/repurposing, incorporates inexhaustible supplies, such as solar energy and municipal waste, and encompasses the husbandry of these resources in a manner that minimizes negative environmental impacts. Anyone involved in the design or manufacture of chemicals, or the upgrade of existing manufacturing processes, will benefit from this book’s suggestions for identifying improvement options, while adding the pivotal aspect of sustainability to the usual cost and safety equation optimization elements.

The 2002 assessment report, produced under the Montreal Protocol on ozone depleting substances, finds that technical progress has been made by the refrigeration, air conditioning and heat pump industry to comply with requirements to phase out CFCs and in several applications, HCFCs as well. However, there is still a significant amount of installed refrigeration equipment still using CFCs and HCFCs, and so service demand remains high and is best minimised by preventive service, containment, retrofit, recovery and recycling.
