Wah Kwong, QIYAO and Bureau Veritas launch feasibility research on carbon seize and storage on ships


Paris La Défense, August 01, 2022 – Bureau Veritas (BV), a world chief in testing, inspection and certification, Wah Kwong, considered one of Hong Kong’s largest shipowners, and Shanghai Qiyao Environmental Know-how Co. Ltd. (QIYAO ENVIRON TEC), a subsidiary of Shanghai Marine Diesel Engine Analysis Institute, have signed a cooperation settlement to check the feasibility of putting in carbon seize and storage (CCS) models on current ships to satisfy 2030 CII targets.

The research will deal with two varieties of bulk carriers in operation within the Wah Kwong fleet. Primarily based on the particular design parameters of the vessels, Qiyao Environnemental Know-how has developed a custom-made design of CCS models for the Wah Kwong fleet and submitted related drawings. BV reviewed the plans based on current rules and guidelines to make sure the security of the vessels and tools, and that the carbon emission discount targets are successfully achieved through the operation of the vessels. Subsequent analysis work can be performed for oil tankers.

The CCS idea developed by Qiyao Environnemental Know-how has accomplished laboratory testing, reaching a complete carbon seize price of over 85% up to now and the system is within the strategy of steady optimization. The CCS unit will be designed for various ship varieties and sizes. The design approval of the CCS unit is beneath evaluation.

The CCS system primarily consists of an absorption unit, a separation unit, a compression unit, a refrigeration unit and a storage unit. The primary precept is that the natural amine compound resolution reacts with the carbon dioxide (CO2) within the absorption unit, separating it from the remainder of the exhaust fuel. The dissolved carbon dioxide compound resolution is desorbed at excessive temperature within the separation tower, earlier than the extracted carbon dioxide is compressed, purified and cooled into liquid carbon dioxide and saved in a low temperature storage tank.
