AbstractAbstract
[en] In this work is to the design of a lab-scale system that was constructed and started up to recover primary by-products of the coke gas, which in his first stage presents displays a mechanism of cooling made up of heat exchanger of double shell to reverse flow, a tower of perforated trays and a closed circuit of water that condenses tars. The second phase contemplates the entrance of the gas in crosscurrent to a tank divided by perforated trays with a permanent water shower, where the ammoniac solutions are concentrated. In order to avoid that the gas remains catches in the pipe of conduction by its high density, it is necessary to suck it by means of an extractor type snail closed, that acts as well like centrifugal separator precipitating the heaviest compounds, and impelling the gas towards a tower where the chemical cleaning of sulfurous and hydrocyanic compounds when reacting with the Lamming mixture takes place, providing a clean and ready gas for consumption. An experimental procedure is developed to test coals samples

AbstractAbstract
[en] This project deals with the demonstration of a coking process using proprietary technology of Calderon, with the following objectives geared to facilitate commercialization: (1) making coke of such quality as to be suitable for use in hard-driving, large blast furnaces; (2) providing proof that such process is continuous and environmentally closed to prevent emissions; (3) demonstrating that high-coking-pressure (non-traditional) coal blends which cannot be safely charged into conventional by-product coke ovens can be used in the Calderon process; and (4) demonstrating that coke can be produced economically, at a level competitive with coke imports. The activities of the past quarter were focused on the following: Conducting bench-scale tests to produce coke and acceptable tar from the process to satisfy Koppers, a prospective stakeholder; Consolidation of the project team players to execute the full size commercial cokemaking reactor demonstration; and Progress made in advancing the design of the full size commercial cokemaking reactor

AbstractAbstract
[en] The coking capacities of the world today come up to 360 million t/a or 200 mill. t/a in the western world alone. Assuming that the specific coke rate of blast furnace will be further reduced and that conde steel production stagnates these capacities are necessary in order to supply the steel industry with the required amounts of coke. A comprehensive analysis of coking plant capacities, especially in the countries of the western world shows that plants are often outdated. Old and badly-maintained plants mean reduced production and closing down of coking plants. This seriously geopardises safety of supplies to the steel industry. Decisions to build new coking plants are there for urgently required. (orig.)

Die derzeit nutzbaren Kokereikapazitaeten liegen bei rund 360 Mio. t/a in der Welt bzw. rund 200 Mio. t/a in der westlichen Welt. Geht man davon aus, dass der spezifische Kokssatz im Hochofen weiter reduziert wird und die Rohstahlerzeugung stagniert, so sind diese Kapazitaeten notwendig, um auch zukuenftig die Stahlindustrie mit dem benoetigten Koks versorgen zu koennen. Eine umfangreiche Analyse der Kokereikapazitaeten, vor allem in den Laendern der westlichen Welt, macht deutlich, dass die dort verfuegbaren Kapazitaeten stark ueberaltert sind. Ueberalterung und auch schlechte Wartung der Anlagen werden zu weiteren Produktionseinschraenkungen und Kokereistillegungen fuehren. Damit ist die Versorgung der Stahlindustrie mit Koks in ernsthafter Gefahr. Es muessen deshalb zuegig Entscheidungen zum Bau neuer Kokereianlagen getroffen werden. (orig.)Original Title

AbstractAbstract
[en] U.S. petroleum coke production has increased 64% during the 10-year period from 1980 to 1990. This dramatic rise makes it timely to discuss the history and future of U.S. coking capacity, production, and processing. The article covers the properties and uses of the various grades of petroleum coke, as well as pricing and market trends

AbstractAbstract
[en] Cathodic protection by pressed current consists in forcing a structure to work as a cathode in a corrosion cell, through an external factor of application of potential across an anode bed. This project studies fine metallurgical coke mixed with additives that possess electric properties like backfill components in anode beds in proportions between 30 and 60% in particle to particle mixture, in order to replace the calcined petroleum coke. For such objective the behavior of these materials is evaluated through a process of cathode protection by printed current at a laboratory level, that is to say, in cells of accelerated simulation so that the best applicable mixture for the above mentioned process can be found. The obtained results show similar behaviors in the performance of the anode bed while protecting a metallic structure.
