6 FAQs about [Battery Grade Sulfuric Acid Production Process]

What is a sulfuric acid plant (battery grade)?

Process Description for Sulfuric Acid Plant (Battery Grade) Gases from the outlet of the CHE/Economiser after CHE are taken to a 25% oleum tower before IPAT. The circulating oleum is boiled to produce SO 3 vapors which are absorbed in a glass/Teflon-lined steel (MS-PTFE) absorption tower. A glass acid cooling system is generally employed.

What are the different processes of sulfuric acid production?

There are different processes of sulfuric acid production: chamber process, single contact, and double contact process. The double contact process is currently the most preferred and widely used due to its high conversion ratio of sulfur trioxide to sulfuric acid.

Can nickel sulfate be used in battery production?

Due to the urgent nickel sulfate demand in the battery field, a short-term solution can be to refine nickel sulfate products from nickel intermediates. In the long term, novel direct battery grade nickel sulfate technologies are needed.

How to produce sulfuric acid from gases from metallurgical sources?

The general presentation of the technique of production of sulfuric acid from gases from metallurgical and other sources is divided into two parts as the techniques for the conversion of SO 2 to SO 3 and of absorption of SO 3 depend on the concentration of SO 2 in the feed gas entering the installation and on the variability of SO 2 concentration.

Does nickel sulfate production affect environmental performance of Li-ion batteries?

Conclusions This study assesses the environmental performance of the production of nickel sulfate that is used in Li-ion batteries. A cradle-to-gate LCA examines the environmental impacts and energy use of a typical HPAL hydrometallurgical process in Indonesia, that produces MHP from low-grade limonitic laterites.

How is sulfuric acid made?

In cases where sulfuric acid is manufactured from elemental sulfur, pyrite or metal sulfide ore as raw material, the process begins with the combustion of sulfur (S) to produce sulfur dioxide (SO 2). S + O 2 → SO 2 Step 2: Sulfur Dioxide Conversion Before sending sulfur dioxide to the converter, it undergoes pretreatment to remove impurities.
