The different photosynthetic plant pigments can be separated by PAPER CHROMATOGRAPHY. It is a methodology used to separate different chemical compounds based on their differential solubility.
This method (paper chromatography) uses paper sheets in order to separate mixtures of soluble substances such as, for example, plant pigments.
These paper sheets represent the 'stationary phase' through which a solution is made to pass.
Subsequently, during the mobile phase, the solvent moves through the paper sheet and thus carries (separates) different compounds with it.

The answer is; Oil shale occurs only in areas with plentiful water resources for processing.
The refinement of oil shale requires a lot of water. This is used to quench the products of retorting and pyrolysis and also reduce dust. The water used becomes heavily polluted and has to be treated before discharge, otherwise, it will be the cause of a major environmental disaster to the local areas.
