The Journal of Process Mechanical Engineering is a quarterly publication for engineers in industry and academe who are concerned with the process industries. The Journal publishes high-quality papers covering a broad area of mechanical engineering activities associated with the design and operation of process equipment. The impact of design on the overall characteristics of the industrial undertaking including maintainability, reliability, sustainability and waste management will remain an important feature of the Journal. The topics covered include: Design; pressure vessels and piping; equipment and components; ventilation and refrigeration; instrumentation and condition monitoring; process applications of thermodynamics and fluid mechanics; maintainability and reliability; hazard analysis; waste management and containment.
