Wison has completed EPC services to enable commercial production at a 300,000 tpa linear low-density polyethylene (LLDPE) plant at Sichuan. This is the last start-up project in PetroChina Sichuan Integrated Petrochemical and Refinery Complex (Sichuan Project). Currently, all the six projects in the Complex undertaken by Wison Engineering have started successful operations, as per Fibre2fashion.com. The Complex, with a total of 19 main units, includes two parts: one is the 10 MTA oil refinery plant and the other one is 800,000 tpa ethylene plant. As one of the main EPC services supplier, Wison Engineering undertook the task of building six main units, including the ethylene cracking furnace and pipe-racks, the Linear Low-Density Polyethylene Plant, the wax oil hydrocracking plant, the integrated paraxylene-aromatic unit (including PSA), the integrated sulfur recovery plant, and the wide-area covering auxiliary units as well. Throughout the three-year construction process, the strong project management team from Wison Engineering achieved a series of innovation and breakthrough in technology improvement, quality management, HSE and project schedule control. For example, one of the most important technical difficulties in the construction of the wax oil hydrocracking unit welding technology for high-pressure thick-walled (= 50mm) stainless steel pipes.
