The world’s first BDO plant has successfully commissioned its energy-saving distillation project featuring a pressurized heat pump for the formaldehyde circulation tower.
Recently, the pressurized heat pump distillation latent‑heat energy‑saving project for the formaldehyde circulation tower at a BDO enterprise in Chongqing—designed, manufactured, and constructed by Turbovap—achieved successful first‑time startup. The operational performance has surpassed design expectations, delivering substantial economic benefits to the customer, with a project payback period of less than one year.
This project integrates key technologies such as low‑temperature‑difference heat exchange, multi‑stage turbine‑driven steam boosting, and ITCC‑based integrated control of the turbine, thereby overcoming the challenges of condensation and heat recovery for formaldehyde‑containing gas mixtures. It represents the world’s first application of pressurized heat‑pump distillation technology for latent‑heat energy conservation in the formaldehyde circulation column of the acetylene–aldehyde route to BDO production.
The successful commissioning of this project marks a major breakthrough for Turbovap in the integration of high-end chemical‑equipment R&D with green, low‑carbon technologies. By innovatively deploying pressurized heat‑pump technology, the project reduces annual carbon emissions by more than 26,000 tonnes, providing a replicable technological model for the chemical industry’s green transformation.
As a specialized manufacturer of multi-stage centrifugal steam compressors and a provider of integrated engineering services, Turbovap has consistently been committed to delivering comprehensive steam‑energy‑saving solutions that create value for its customers.
