In 2005, SGHK LLP acquired an idle sulfuric acid plant (SAP), which was located in close proximity to the main industrial site of SGHK LLP in Stepnogorsk.
As a result of the launch of sulfuric acid production, for the first time in Kazakhstan, the production was transferred from ferrous sulfide, lump sulfur (Tengizchevroil LLP) to Kazakhstani raw materials and one of the main tasks was fulfilled - to ensure own needs for sulfuric acid, as well as enterprises of NAC Kazatomprom JSC".
Every year, the need for sulfuric acid increases. In 2006, 448.993 thousand tons were required for production needs, and by 2015 it was already 1769.519 thousand tons.
So, in view of the need for stable supply of sulfuric acid of its own production and enterprises of NAC Kazatomprom, as well as the physical and moral deterioration of the existing sulfuric acid production, the question arose of the reconstruction of the sulfuric acid production of SGHK LLP.
The new installation was located at the production sites of the existing sulfuric acid production of SGHK LLP, taking into account the use of the existing infrastructure of the enterprise (buildings and equipment currently available and in working condition, such as sulfur and finished products warehouses, raw material unloading unit from railway transport, water cycle, chemical water treatment, tail gas cleaning unit, driveways and railway tracks, office buildings and a canteen), which led to cheaper total project cost.
