  “Nizhnekamskneftekhim” developed the technology of propane purifying


As reported by press-service of “Nizhnekamskneftekhim”, on March 25, 2009, the Company developed the technology of propane purifying for production of polyethylene.

This technology has been known already but it was the first time when it was used in commercial scale by OJSC “Nizhnekamskneftekhim”. Propane being one of the feedstock components of polyethylene production is produced by Divinyl and Hydrocarbon resources plants. Nevertheless, produced propane contains the additive of methanol.

After some transformations of the unit for production of hexane dissolvent «Nefras», the specialists of production shop № 1428 developed the assembly for production of propane. The team of this shop managed to reduce the content of additive in tens of thousands times and bring this index up to 0,0005 %.
In March 2009, the shop produced the significant volumes of purified propane that will be used during the production of polyethylene.
