In mid-March 2026, an important construction milestone was reached for the integrated project for the comprehensive utilization of alkane resources at Zhejiang Yuanjin New Materials Co., Ltd. The main structure of the extrusion granulation plant, the core facility of the 2×300,000 tons/year polypropylene plant constructed by the Shanghai branch of China National Chemical Engineering Third Construction Co., Ltd., has been successfully completed, marking a significant milestone in the construction of this plant. As a key production facility in the polypropylene plant, the extrusion granulation building, whose construction was completed recently, features a frame-type structural design. It has 5 floors in total and an architectural height of 41 meters, presenting challenges such as a high degree of structural complexity and difficulties in vertical construction. Key milestone review: On the afternoon of March 5, the company held a mobilization meeting at the project site to launch a 200-day intensive effort to ensure completion of the project by October 31. Construction and management units such as Sinochem Second Construction Group Co., Ltd., China National Chemical Engineering Corporation Third Construction Company, China National Chemical Engineering Corporation Thirteenth Construction Company, China National Chemical Engineering Corporation Sixteenth Construction Company, and Qilu Petrochemical Engineering Co., Ltd. attended the meeting. The meeting set the goal of achieving full completion by October 31, assigned tasks for two phases of effort, and launched a labor competition titled the \"100-Day Campaign\" from March 15 to June 30.
