Alternative Energy Sources, CO_2 Recovery Technology and Clean Environment Compliance -- Integral Components of Energiron Technology

摘要

The alliance between HYL Technologies, Techint/Tenova and Danieli brings a new brand -ENERGIRON-to the forefront of the direct reduction industry. Current environmental regulations not only in the EU but worldwide bring more stringent demands to the design of industrial plant operations of all Hypes. ENERGIRON technology is characterized by its flexible process configuration which is able to satisfy and exceed these requirements. In regions where either the high cost or low availability of natural gas work against this traditional energy source, the process is easily configured to operate using coke oven gas, syngas from coal synthesizers and other hydrocarbon sources. More importantly, the air and water effluents of the process are not only low but easily controlled. Incorporation of selective CO_2 removal systems has been a key factor over the past decade in reducing significantly the emissions levels, providing an additional source of revenue for the plant operator via the captured CO_2. The high pressure operation and closed system of an ENERGIRON plant combined with the HYTEMP Pneumatic Transport System reduces dust emissions to both air and settling tanks, making the process more economical and environmentally friendly. This paper will review the design configuration and economic impact of these green technologies.
