煤气化焦油中固体物的脱除

试验研究了脱除煤气化焦油中固体物的4种方法,讨论了真空过滤、真空蒸馏、离心分离、加压过滤等方法的优缺点,得出最有应用前景的首选方法。 Four methods were adopted for removal of the solid in the tar which is derived from coal gasification process. The advantages and disadvantages of the four methods, which are vacuum filter, vacuum distillation, centrifugal separation and presurized filter, have been compared and discussed. The best method that possesses good appplication prospects has been gained
