Hoto achieves milestone with 60 KTA 1-butene unit

Hoto Engineering, in partnership with Shanghai BSyn Petrochemical Technology Co., Ltd., is delighted to announce the successful commissioning of the 60 KTA 1-butene unit at CNOOC Ningbo Daxie Petrochemical Ltd. on March 2, 2024.

This achievement marks a significant milestone in the adoption of the jointly licensed "Selective Hydrogenation + Super Fractionation + 2-Butene Isomerization + Etherification Deisobutenization + Precision Distillation" integrated process, known as B-TIO Pro.

The B-TIO Pro technology boasts broad feedstock adaptability, high 1-butene yield, superior product quality, low overall energy consumption, and operational flexibility.

By utilizing the etherification of post-ether carbon four as raw material, the 1-butene unit at Daxie Petrochemical produces high-value polymer-grade 1-butene while effectively harnessing low-temperature heat recovery.

During the project construction phase, Hoto's project team formulated an exemplary layout plan to overcome challenges such as limited land availability and existing equipment layout constraints.

Their meticulous organization and dedication ensured the timely and successful completion of process package and engineering design tasks, earning commendation from the construction unit.

Throughout the commissioning phase, Hoto Engineering dispatched expert teams to provide on-site technical guidance and support, swiftly addressing issues to ensure the production of qualified products according to schedule.

The smooth operation of the 1-butene unit showcases Hoto's outstanding design capabilities and the advanced nature of B-TIO Pro 1-butene integrated technology. This success not only enhances the company's brand reputation but also signifies a crucial step towards transitioning to high-end chemical business.
