Abstract
A system for the manufacture of synthetic hydrocarbon products from coal or similar carbonaceous solids is described. This coal liquefaction system includes means for reducing the pressure of high pressure and temperature liquid reaction product streams without attendant corrosion of the metal parts in the pressure reducing unit. The pressure reducing means comprises at least one elongated tube defining relatively narrow fluid flow passage, the reduction in pressure being effected substantially entirely by friction of the fluid within the tube.
