oa Civil Engineering = Siviele Ingenieurswese - A still for the recovery of methylene chloride used in bitumen extraction
The design of a simple and effective still for the recovery of methylene chloride used in bitumen extraction is presented and discussed. The apparatus meets all requirements of safety, simplicity and ruggedness likely to be demanded of it in use in materials laboratories in general and site laboratories in particular. Sufficient detail is given to enable similar apparatus to be fabricated at low cost from readily available materials with a minimum of specialized tooling or workshop expertise.
