Aspen Plus is on of the most popular process simulation software programs used industrially and academically. Though the software is available at many corporations and universities, there are no textbooks which are dedicated to teaching the step–by–step use of the software. This book is designed to fill that need. The structure of the book is unique in that it emulates a lecture /workshop classroom environment. Each chapter starts with the equivalent of a classroom lecture followed by workshops which provide experience in the chapter′s subject matter. The enclosed CD contains solutions, both in Aspen Plus and text formats, to examples imbedded in the text  as well as to all the workshops. There are also notes at the end of each chapter designed to aid readers that have difficulty with the workshops. Note: CD–ROM/DVD and other supplementary materials are not included as part of eBook file.
