The method of cold liquid removal is to dissolve the mixture in a warm form of this colorless liquid and then swiftly cool it. Each compound in the mixture has its own solidifying temperature which helps in taking out the required substance.

This combined method agitates the surface and loosens the particles from the surface. Carpets and rugs are generally cleaned this way by the cleaners.

Essential oils need both hot and cold methods to be removed from plants and are an expensive process. The hot steam liquidates the oils from the plant and the hot steam and oil rise up. This is passed through a cold area where they again come back to liquid form. The oil naturally floats up and can be now taken off.

Essential oils from plants can also be removed with the help of cold liquid and again a lengthy process. This is usually applied to take out oil from oranges, lemons and grapefruits. The rinds of these fruits are cut into pieces, soaked and pressed in this natural liquid. After sometime the oil forms a film on the top and is easily skimmed off the surface. However, the resulting oil does not have a long shelf life.

Water, pressure, high and low temperature are all ingredients for any removal of substance or particle or compound from its resting place. When heat is used in the removal method it is important to keep an eye on the degree. Higher than the required temperature can also destroy the main item and make the whole process useless.
