MATEUS, Elisabete M. et al. Pilot Steam Distillation of Rosemary (Rosmarinus officinalis L.) from Portugal. Silva Lus. [online]. 2006, vol.14, n.2, pp.203-217. ISSN 0870-6352.

While considering the project and the economic evaluation of an industrial steam distillation unit for essential oils there is a need to take into consideration that full extraction will need a lot of steam and that the length of the operation will determine the processing capacity of the unit. One must also quantify and dimension the equipment according to seasonal variations and associated processing peaks. Pilot tests are useful in obtaining data to cope with this problems and dimensioning industrial stills. Portuguese Rosmarinus officinalis L. is evaluated as an example.
