INVT GD880 VFD for Coal Slurry Pump System Upgrade in Inner Mongolia Coal Chemical Project

The coal-to-olefins project of a coal chemical company in Inner Mongolia is a super-large coal chemical project that uses coal as raw material to produce polyolefins. Since it was put into trial operation in 2010, it has undertaken the significant responsibility of leading the healthy development of China’s new coal chemical industry. The project employs the domestically developed SDTO (Synthesis-to-Olefins from Methanol) technology, encompassing four core processes: coal gasification, synthesis gas purification, methanol synthesis, and methanol-to-olefins conversion.

In such a critical project, the stable operation of every technological component is paramount. As a vital part of the system, the performance of the drive equipment for the coal slurry pump system directly impacts the efficiency and stability of the entire production process.

1. Customer Requirements

The imported brand frequency converters previously used by the customer have been in operation for many years, with the service life of equipment components nearing its limit. Frequent malfunctions have significantly impacted normal production operations. To ensure production continuity and stability, the customer has decided to optimize and upgrade the relevant products.

Specific requirements are as follows:

-Smooth alternative to imported equipment:

Without modifying the existing production system, simply replacing the VFD enables stable and reliable operation, ensuring production remains unaffected.

- Meets on-site installation requirements:

New equipment must meet on-site operational requirements, with installation dimensions seamlessly matching the reserved space at the site.

2. INVT Solution

Based on customer requirements for delivery cycles, pricing, and production stability, Invt has launched the GD880 series engineering drive frequency converters. These products represent a software, structural, and component optimization upgrade from the GD880 series engineering drive frequency converters. Building upon the high reliability of the GD880 platform, they meet the demand for flexible configuration of unit modules and cabinet units. The design is more compact, installation and maintenance are more convenient, and protection features are more comprehensive.

3. Solution Value

Through this localization upgrade, the INVT GD880 series products and solutions have achieved substitution for imported brands.

-In terms of reliability

Reliable component selection ensures product quality from the design stage, delivering high reliability and stability. This approach has been proven in numerous field applications, guaranteeing stable equipment operation while reducing labor maintenance and equipment costs.

-In terms of compatibility

Supports mainstream communication protocols such as CANopen, Modbus, ControlNet, DeviceNet, EtherNet/IP, PROFIBUS, and PROFINET, enabling compatibility with various higher-level control systems and enhancing the automation level of the entire production system.

- In terms of performance

With outstanding performance and key technical indicators matching those of imported brands, it provides a strong guarantee for the efficient operation of coal slurry pump systems.

- In terms of after-sales service.

INVT 24/7 after-sales service system ensures on-site problem resolution within 24 hours.

The successful application of INVT GD880 series engineering frequency  drive in a coal slurry pump of a coal chemical enterprise in Inner Mongolia has achieved the goal of domestic substitution for imported brands, adding a considerable performance to the company in the project of upgrading and reusing old equipment. In the future, INVT will continue to increase investment in research and development, constantly improve product performance and service level, provide more customers with high-quality industrial automation solutions, and promote the development of China's industrial automation industry to a new height.
