There has been significant development in chemical processing equipment over the past decade; may China continue to thrive and prosper. Wishing everyone a happy New Year, and may their families be safe and healthy. I hope this post will inspire further discussion from everyone – with more participants, the forum will become even more lively. Haichuan is better with you all here; feel free to participate more actively in the discussions on this forum. ********************************************** On January 14, 2023, the 150,000 tons per year CHP-based propylene oxide (CHPPO) production plant in Tianjin, which was constructed under the EPC contract by Sinopec Shanghai Engineering Company, was successfully commissioned in just one attempt. The plant was able to produce propylene oxide of high quality, with a purity of 99.99%. The successful commissioning of this unit marks the first large-scale industrial demonstration application of Sinopec’s own CHP-based propylene oxide technology. This project utilizes Sinopec’s own process technologies and is one of Sinopec’s “Ten Dragon” key research projects; it was developed jointly by Tianjin Petrochemical, Shanghai Petrochemical Research Institute, Shanghai Engineering Company, and Anhui Institute of Technology. The device features low energy consumption in production, is environmentally friendly, and offers high operational safety.
On April 21, 2022, the first KM-403 compressor of Tianjin Petrochemical’s 150,000 tons per year CHP-based propylene oxide production project, constructed by Sijian Company, completed its no-load test successfully. The operational data showed that all mechanical parameters met the design specifications, laying the foundation for the commissioning of the facility. It is reported that the new hydrogen compressor KM-403 features a two-row, first-stage symmetrically balanced layout. Due to the high installation precision required for this compressor unit and the complexity of the manufacturing process, all of the process gas pipelines and auxiliary pipelines for the compressor are prefabricated in the manufacturer’s facility. The compressors are arranged in a single-layer layout and delivered as a complete skid unit; on-site, they are disassembled for inspection and their internal components are reinstalled. To ensure the smooth installation of the unit, a leadership team for compressor installation and a group of technical experts were established. The project manager, senior technicians, and technical experts held numerous meetings to discuss the matter and develop a viable installation plan. To overcome the impacts of the pandemic during the installation process, video conferences were held multiple times with the manufacturer to provide on-site guidance. The company coordinated with the construction workers from various aspects to meet the requirements for compressor installation; 6 special meetings were held to confirm the conditions for commissioning, during which the installation of each instrument and the layout of pipelines were checked, and issues such as missing materials and instrument interlocks at the site were addressed through coordination.
