WORLD DIRECT REDUCTION STATISTICS
Production of DRI in Iran was a record 28.5M tons, all from natural gas-based processes. This was a 10.9% increase over 2018. The MIDREX Process accounts for nearly 92% of DRI production in Iran. Several MIDREX Modules that either start - ed production or ramped up during 2019 were responsible for the bulk of the growth.

Towards fossil-free steel: Life cycle assessment of biosyngas …
The biosyngas DRI production system was developed in the earlier work (Zaini et al., 2023) to produce hot DRI with 92% metallisation and 2% carbon content. The proposed system comprises a biomass dryer, a gasifier, a tar reforming, a gas heater, a DRI shaft furnace (similar to the MIDREX furnace), and a CO 2 separation process, as …
Sustainability Enhancement of the Coal Based Direct
Raw material utilization and waste generation for the DRI suggest that 1.6 tonnes of ore,1.2 tonnes of non-coking coal and 0.05 tonnes of dolomite are needed to produce 1 tonne of sponge iron and 0.2 tonnes of solid wastes [2, 5].This implies that for every 10 tonnes of sponge iron produced, almost 2 tonnes of solid wastes are produced …
Global production of DRI increased by 7 percent in 2023
India accounted for over 36% of the total DRI production. During the year, Indian companies produced 49.33 million tons of the product, which is 16.7% more than in 2022. Iran, the second largest DRI producer, increased its output by 1.7% y/y – to 33.45 million tons. The share of Iranian DRI in global production was 24.7%.

Direct reduced iron plant
A Direct Reduced Iron plant is a furnace that produces Direct Reduced Iron (DRI), also referred to as sponge iron due to its porous nature. The process can also produce Hot Briquetted Iron (HBI). The iron can then be used to produce steel via other production routes, such as the Electric Arc Furnace (EAF). The process uses iron ore …

The Value of DRI – Using the Product for Optimum Steelmaking
DRI production in 2013 hit 75.22 million tons compared to only 23.65 million tons twenty years prior in 1993 and only 49.5 million tons in 2003. Accordingly there are very few individuals even remotely associated with the iron and steel industry that do not know of DRI and its forms as Hot DRI (HDRI), Cold DRI (CDRI) and Hot Briquetted Iron (HBI).

Decarbonisation of steel production by the low‐carbon DRI…
However, the production of 1 tonne of steel, in the coal-dependent BF/BOF route, can lead to about 2.3 tonnes of CO 2, and this route is responsible for more than half of all steel produced in EU. Therefore, finding alternative breakthrough technologies to reduce CO 2 emissions is a priority for the steel industry, and different decarbonisation ...
