Capsule Pipelines – Technical

This page collates some technical sources of information on capsule pipelines. These may be useful for people that want to examine engineering aspects of capsule pipelines, although currently it lacks detailed technical content, which tends not to be freely published.

Other PCP Papers

Those interested in technical aspects of PCPs, may try to find the following:

  • Verlag, D., (c1970), ‘Rohrpostanlagen’ – describes German advances in large and small diameter systems in the late 1960s, a ‘state of the art’ prior to the development of PCPs using booster pumps; almost impossible to find. (Also attributed to Richard Kirchheim.)
  • Carstens, M., (1970), ‘Analysis of a low-speed capsule-transport pipeline’, presented at Hydrotransport 1, 1-4 September 1970, University of Warwick – the first technical paper for PCPs using booster pumps.
  • Round, G., Marcu, M., (1987), ‘Pneumocapsule pipelines: potential for North America’, Journal of Pipelines, 6, 221-238, Elsevier – probably the best detailed work, drawing on the research into PCPs that followed in the wake of Carstens.
  • Liu, H. (2003), Pipeline Engineering, CRC Press.
