Recently, the Ocean Carbon Capture System (OCCS), developed by Shanghai Qiyao Environmental Technology Co., Ltd, (Qiyao Environ Tec) a wholly-owned subsidiary of Shanghai Qiyao Technology Group Co., Ltd (Shanghai Marine Diesel Engine Research Institute), which covers the whole process of absorption, compression, liquefaction and storage, has successfully completed the trial voyage and was delivered successfully.
Suitable for 14,000 TEU large container ship EVER TOP, this system is equipped with a full set of functions such as absorption, compression, liquefaction and storage, and all the performance indexes meet the technical requirements and design standards.
Onboard carbon capture technology utilizes amine absorbents to selectively capture and separate CO2 from ship exhaust, and compresses and liquefies the CO2 into liquid form for transportation, storage or utilization. The OCCS mainly consists of absorption module, regeneration module, compression and refrigeration module and storage module.
Qiyao Environ Tec has successively broken through the key technologies of high-efficiency CO2 capture technology, low-energy CO2 separation technology and low-temperature CO2 deep liquefaction, and developed a prototype of OCCS with independent intellectual property rights, in which the comprehensive CO2 capture rate of the system reaches more than 80%, and the purity of analyzed CO2 reaches more than 99%.
Also, by utilizing new adsorbents, zoning process parameters control and other core technologies, the energy consumption of the OCCS has been greatly reduced, and all indicators have reached the international top level.
It is the world’s first CO2 capture system project covering the whole process of absorption, compression, liquefaction and storage. It is the result of Qiyao Environ Tec’s years of innovation and technology transformation in the field of ship emission control, which is of great significance in promoting the construction of industry standards and supporting IMO’s strategic decision on greenhouse gas emission reduction.
