This text investigates the methodologies and mathematical frameworks required to accurately estimate capital and operating costs for chemical process plants. Authors Robert S. Aries and Robert D. Newton provide a structured approach to economic evaluation, drawing upon industrial engineering principles to assist practitioners in project feasibility studies. The work establishes a systematic basis for calculating equipment costs, installation expenses, and overall plant investment requirements.

Experts recognize this as a foundational reference for traditional chemical engineering economics. Readers frequently note the technical density of the prose and the reliance on historical cost data, which requires adjustment for current market inflation.
