Contract Mode: PC
Time: 
• Phase I: July 2017 – October 2018 (Module Shipment)
• Phase II: April 2019 – September 2020
Project Description:
• Phase I: 1.4 MMTA Ethylene Unit – Cracking Furnaces (S&W Technology)
• Phase II: 1.4 MMTA Ethylene Unit (S&W Technology)
• One of the world’s largest integrated refining and petrochemical complexes
• Phase I: Featured the world’s largest single liquid feedstock cracking furnace constructed using a fully modularized approach, with a 9×200 KTA ethylene furnace section delivered via combined sea and land transportation
• Phase II: PC general contracting for the 1.4 MMTA ethylene unit, completed within only 18 months, honored as a 2021 Excellent Quality Project in the Chemical Industry

The project, located in Zhejiang Province, China, involved a 30,000-ton modular construction for nine 200 KTA ethylene cracking furnaces. Wison provided full services from detailed design and shop fabrication design to procurement, fabrication, shipping, marine lashing, transport, offloading, and site installation. Each furnace, with an annual ethylene capacity of 200,000 tons, weighed 3,689 tons and stood 53 meters tall. The process modules integrated complex equipment, including quench exchangers, steam drums, and SCR units, making them the largest liquid feedstock cracking furnaces ever delivered as fully modularized units worldwide. The successful delivery of these modules marked Wison Engineering’s first large-scale modular construction project for an ethylene cracking plant.
