It received the second prize of the Jinchuan Group science and technology advancement awards and the third prize in the Gansu science and technology advancement awards in nonferrous metallurgy.

Cao’s self-developed operating method is designed to shorten the time for turning on oxygen-making machines via refilling liquid nitrogen. It has been listed as one of the provincial-level advanced employee technology innovation production methods in Gansu. The energy conservation project of a hydrocarbon control system for liquid oxygen evaporators of oxygen generator dephlegmators that he initiated saves more than 300,000 yuan per year in energy.

Cao has played a leading role in the research and development of dozens of award-winning high-tech devices such as liquid filling mechanisms for cryogenic liquid tankers and leak hunting and core-pulling devices for large-scale imported air compressor coolers.

During the past few years, Cao has obtained eight technological innovation achievements, completed maintenance of large-scale and key equipment 33 times, and solved over 40 technical problems in production and machinery maintenance.

Of three employees Cao has trained, one has become a key technician in the building of air separation projects while two become technical experts in oxygen generation and air supply.
