41. The special plates ( known as disc stacks ) increase the surface settling area which speeds up the separation process . 42. Direct provision of heat involves the combustion of fuel in the calciner itself ( air separation processes are being developed. 43. Eventually, as they get pulled thinner, each strand breaks _ the " snap " _ to complete the separation process . 44. This fermentation of hydrogen is accompanied production of carbon-dioxide which can be separated from hydrogen with a passive separation process . 45. These oils typically use fractional crystallization ( separation by solubility at temperatures ) for the separation process instead of distillation. 46. The newest development in decanter centrifuge technology aims to achieve enhanced control of the separation process occurring inside the decanter. 47. Once the separation process is completed, surgeons will have to reconstruct their skulls and cover the wounds with skin, Thomas said. 48. Synthetic membrane chemistry usually refers to the chemical nature and composition of the surface in contact with a separation process stream. 49. Stripping is a physical separation process where components can be removed from a liquid stream through usage of a vapor stream. 50. Modern mining practices tend to favor dry mining rather than dredging operations, due to the advent of electrostatic mineral separation processes .
