The flow d iagram shows a typical use o f Fansteel-built Tantalum Absorption plants in converting by-product hydrogen chloride gas from a chlorinating operation into marketable hydrochloric acid. The diagram also shows a tantalum sparger tube for introducing chlorine into the reaction kettle and a tantalum reflux condenser to recover the chlorinated product.

The overall economy of tantalum HC1 ab­sorbers is (1) complete freedom from corro­sion, (2) freedom from thermal shock, (3) l o w

consumption of cooling water, (4) no contami­nation o f product ac id , (5) prec i se c o n t r o l and immediate response to adjustment, (6) con­servation of space, (7) s imple installation and operation, (8) low maintenance.

Fansteel Absorption Plants, each built for its particular service, are performing splendidly all over the world. We will welcome a consul­tation on your requirements—for better service at lower cost. Fansteel Metallurgical Corpora­tion, North Chicago, Illinois.
