During long years of polypropylene production, Hipol several times changed its process. The most effective improvement was the catalyst change, from classic Ziegler - Natta to high activity one. Utility consumption decreased significantly; some process chemicals and plant equipment treating them become unnecessary.
Having unused items of plant equipment was a major challenge, accepted by our researchers.
LPG from gasoline
|
|
There are a lot of LPG production processes. Hipol developed its own process, based on gasoline continuous distillation. With minor modifications, the existing plant equipment, auxiliary systems and manpower is used, not influencing polypropylene production. Main product is standard autogas LPG, with valuable byproducts, mainly pure heavy hydrocarbons. Hipol offers a complete service, including unloading/loading manipulation, LPG production, row material and product storage, ISO 17025 accredited laboratory tests, ISO 9001 certified quality assurance. |
Propane/propylene fraction purification
 |
Mandatory requirement of any propylene polymerization process is high purity of the raw material propylene, usually over 99%. On the market, chemical grade of 92-95% or polymer grade of more than 99,5% purity are available. Staying on grassroot, Hipol is equiped with a powerful purification unit. It can accept C3 fraction with 75% propylene content. Product of the purification is polymer grade propylene. The byproduct is propane, usable for LPG mixing. The usage of C3 fraction does not influence the polymer quality, but only seldom operaters can so vigorously purify it. There is a brand new economics, with increased purification, and much decreased raw material cost. Hipol offers the purification service, with all the necessary auxiliaries. |
