With the whistle blowing to mark a new journey, well-crafted equipment sets off for its destination. Recently, the hexane rectification tower manufactured by Henan Huatai Petrochemical Equipment Co., Ltd. has successfully completed fabrication and inspection, and been delivered as scheduled to the project site.

Adopting China’s DMTO-Ⅲ (3rd-generation Methanol-to-Olefin) technology to revamp the MTP process, this project serves as a key practice for the industry to advance toward high-end, diversified and low-carbon development. Huatai undertakes the fabrication of 14 critical towers including the hexane adsorption tower, butene tower, ethylene acetylene & oxygen removal refining tower, and 1-butene drying tower. Among them, the hexane rectification tower features a diameter of 2.2 meters, an overall length of nearly 28 meters and a weight of approximately 27 tons.

As core equipment for chemical separation processes, the hexane rectification tower is responsible for purification and rectifying separation of hexane components. Its operational stability and fabrication accuracy directly determine the product purity, energy consumption and long-term safe operation of the whole plant. Characterized by large overall dimensions and long cylinder body, the equipment imposes stringent requirements on material control, welding quality, geometric tolerance, non-destructive testing (NDT), heat treatment and other procedures. The entire fabrication process is implemented in strict compliance with pressure vessel codes and the client’s technical specifications.

Since the project kicked off, the company has attached great importance and set up a dedicated project team to coordinate the whole workflow covering drawing review, material procurement, process planning, production fabrication and quality inspection. The workshop arranged production precisely with close coordination among all working procedures. Welders, NDT inspectors, riveters and other frontline staff strictly control every process. The quality department provided full-process supervision, conducting item-by-item acceptance at key checkpoints including raw material re-inspection, assembly & welding, non-destructive testing and pressure test. Every detail was rigorously managed to ensure all technical indicators of the equipment meet design documents and codes, delivering safe and reliable products.

To tackle difficulties in manufacturing oversize equipment, the technical team carried out advance assessment, optimized fabrication plans, and formulated special plans for cylinder assembly, straightness control and transportation protection. Prior to shipment, all inspections and tests were finished. Internal and external anti-corrosion protection and marking fixation were completed, while an oversize cargo transportation plan was put in place to reduce the risk of collision and damage during transit for smooth delivery to the construction site.

This cooperation fully recognizes our capability for pressure vessel fabrication, quality management system and delivery performance, and creates an important opportunity for deeper collaboration between both parties. Long committed to petrochemical equipment manufacturing, the company holds the A2 pressure vessel manufacturing license. We continuously supply clients with custom non-standard towers, heat exchangers, pressure vessels and other complete sets of equipment, adhering to the philosophy of building premium products with craftsmanship and honoring credibility through quality.

The company always treats every hardworking sales elite with care, giving back to everyone's every effort with full benefits and heartwarming team building.The successful shipment of this hexane rectification tower marks an important milestone of the project. Going forward, we will keep close communication and provide supporting services to fully coordinate on-site installation. In the future, we will consistently uphold the bottom line of safety and quality, refine core manufacturing technologies, and provide high-quality equipment support for clean coal conversion and high-quality development of the coal chemical industry. We will work hand in hand with clients to build a new landscape of green and efficient energy and chemical sector.
