Title: Innovations of Snigdha Priyadarshini in Eco-Friendly Iron Production

Introduction

Snigdha Priyadarshini is a prominent inventor based in Bhubaneswar, India. She has made significant contributions to the field of eco-friendly iron production, holding 2 patents that focus on innovative processes for preparing high purity iron and direct reduced iron (DRI). Her work emphasizes sustainability and reducing carbon emissions in industrial processes.

Latest Patents

One of her latest patents is titled "Green process for the preparation of pure iron." This invention relates to an eco-friendly and single-step process for producing high purity iron using hydrogen plasma in a suitable smelting reactor furnace. The process achieves a reduction of iron oxide in excess of 99% by utilizing a hydrogen plasma smelting system. The quality of the product is significantly improved as it eliminates coke inclusion, which typically carries impurities such as carbon, sulfur, phosphorous, and silica. Additionally, this method greatly diminishes carbon dioxide emissions, making it highly eco-friendly. The only by-product of this process is water, addressing the greenhouse effect by avoiding gases like carbon dioxide and carbon monoxide during operation.

Another notable patent is "Green process for the preparation of direct reduced iron (DRI)." This process involves obtaining DRI from iron ore through reduction using microwave-assisted low-temperature hydrogen plasma. The steps include loading iron ore onto a sample holder, placing it inside a chamber, evacuating the chamber, and introducing hydrogen gas at a controlled flow rate. The sample is then heated at specific temperatures and pressures to obtain DRI, which is subsequently cooled by flowing hydrogen.
