VPSA for Oxygen Production: Principles, Operation, and Engineering
Santos, Dr. Ronaldo Santana
Synopsis "VPSA for Oxygen Production: Principles, Operation, and Engineering"
The world’s first book dedicated exclusively to VPSA oxygen production—not as an extension of conventional PSA, but as a comprehensive system, from core physics to investment decisions. This book deconstructs the logic behind every valve, component, and design choice—from the adsorption physics underlying oxygen separation within the zeolite bed to the eight-step cycle, operational risks, maintenance strategies, and the practical criteria that determine when the technology should—or should not—be selected. Built on more than three decades of hands-on experience across operating plants in Latin America, this is not an operations manual. It is a framework for understanding—written for engineers, executives, and investors responsible for the asset; hospital administrators and legal professionals who rely on the system without operating it directly; and students and rising professionals in the gas sector seeking a rigorous, systemic foundation. Why This Book Exists Thousands of VPSA oxygen plants operate worldwide, supporting hospitals, industrial facilities, and critical infrastructure. Yet knowledge of this technology remains fragmented—buried in isolated chapters of generic texts on PSA and gas separation, and almost always written strictly for chemical engineers. Until now, no single work has treated VPSA as its central subject. This is the first. What You Will Find in This Book The complete mechanics of a VPSA plant: from ambient air intake to the eight-step adsorption and regeneration cycle System hardware—filters, blowers, vacuum pumps, adsorber vessels, automated valves, and compressors—and the precise function of each within the process logic Real-world oxygen hazards in industrial and healthcare environments, and how they are controlled A comparative analysis of VPSA against PSA, electrolysis, membranes, and cryogenic distillation—including the technical and economic benchmarks that drive technology selection Maintenance as a core reliability strategy rather than a routine task About the Author Ronaldo Santana Santos holds a Ph.D. in Mechanical Engineering from UNICAMP, a Master’s in Production Engineering from UFRGS, and a Bachelor’s in Business Administration from PUCRS. With over thirty years of experience in the industrial and medical gas sectors, his expertise spans core production technologies at the intersection of critical processes, corporate strategy, and governance. He has directed higher education programs in Engineering and Management and served in professional education programs with the Brazilian Society of Hyperbaric Medicine (SBMH) for healthcare professionals. Currently, he serves as a strategic advisor to companies that consume, self-produce, or purchase gases on a merchant basis across Latin America—managing recurring engagements in Brazil, Chile, Colombia, Paraguay, and Guatemala—and assisting C-level executives and leadership teams in evaluating and restructuring critical asset decisions before their consequences become irreversible. Recognizing the absence of a work dedicated exclusively to VPSA technology, Dr. Santos synthesized decades of field experience into this groundbreaking volume: an applied, systemic foundation for leaders managing decisions where risk, reliability, and technical excellence leave no margin for error. In parallel, Dr. Santos developed Investability Engineering™—an original discipline focused on the institutional legibility of CAPEX-intensive assets for global capital markets. This concept forms the foundation of his upcoming book: Investability Engineering: Why Technically Viable Assets Fail to Attract Global Capital.
