✦ Synopsis
The national production of coal fell by 10% to 35.8 million t in 1971, and similarly the total used fell to 52.75 million t. The national production of coke has been 12.5 million t, and 2.7 million t has been imported. The coal is used as follows: carbonization 16 Mt, briquetting 3.6 Mt, electricity production 19.1 Mt.
The CERCHAR process for coke production from preheated coal has been successfully used at the Ironton works of the Allied Chemical Corporation.
An improved process for charging the ovens has been introduced by the American firm.
This process will be operated by the Association COALTEK, affiliated to Allied Chemical, and the company Salem & Gibbons.
It reduces considerably the atmospheric pollution, benefits productivity by about 40%, and permits coals considered difficult to coke to be used.
