Project

Project Polypropylene (PP) Production Plant & Liquefied Petroleum Gas (LPG) Warehouse at Hyosung Chemical Plant – Cái Mép Industrial Zone, Tân Thành, Bà Rịa – Vũng Tàu Province, covers an area of 60 hectares, with a total investment of approximately 27,000 billion VND, led by Hyosung Group – Hyosung Chemical Corporation, South Korea.

The complex will include 1 PDH unit, 2 PP plants, 1 LPG tank, and 1 storage warehouse for both LPG and PP. PP is a type of thermoplastic used in various applications, including packaging and labeling, textiles, office supplies, plastic parts, reusable containers, laboratory equipment, speakers, automotive components, and polymer banknotes.

STORAGE TANK

Spherical Tanks are distinctly globe-shaped pressure vessels renowned for their inherent structural strength and uniform stress distribution. Their primary function is the extremely efficient and safe storage of very large volumes of high-pressure gases or liquefied gases, such as LPG, ammonia, and oxygen, with minimal material usage and superior resistance to internal pressure. These iconic pressure vessels are a common sight in petrochemical plants, oil refineries, chemical facilities, and industrial gas production sites, where high-volume, high-pressure storage is paramount.
