This legacy project page is retained at its original address, but its project attribution has not been verified.
Scope recorded in the original archive
The original page is internally inconsistent: its heading names CHETRA, while the body describes a Liaoyang petrochemical project. It records almost 20 months of Chinese–Russian and Chinese–English work and lists equipment manuals, technical proposals, materials manuals and physical-property data. The project identity needs confirmation before this entry can be used as a verified reference.
This is a historical project record, not a statement of a current contract or client endorsement.
