日本企業(yè)推進(jìn)世界首個海洋碳捕獲系統(tǒng)計劃

據(jù)石油新聞2020年8月31日新加坡報道，隨著航運(yùn)業(yè)向脫碳方向發(fā)展，日本三菱重工集團(tuán)旗下的三菱造船有限公司時下正與日本航運(yùn)公司川崎汽船有限公司和船級社日本海事協(xié)會一起推進(jìn)一個旨在對小規(guī)模船基二氧化碳捕獲示范廠進(jìn)行試運(yùn)行和測量的項目.

2018年4月，國際海事組織（IMO）宣布了其改善航運(yùn)中二氧化碳效率的溫室氣體戰(zhàn)略和目標(biāo)。IMO設(shè)定了到2050年前航運(yùn)業(yè)溫室氣體排放量比2008年減少50%的目標(biāo)。

三菱造船有限公司在8月31日的一份聲明中表示，這個名為“海洋碳捕獲”的項目打算實現(xiàn)全球首個海上二氧化碳捕獲。

聲明說，作為其海洋資源開發(fā)技術(shù)進(jìn)步研究和開發(fā)援助項目的一部分，這個項目得到了日本國土、基礎(chǔ)設(shè)施、交通和旅游省旗下的海事局的支持。

這個示范廠將在2021年年中投產(chǎn)，在示范廠運(yùn)行測試以后將安裝在由川崎汽船有限公司運(yùn)營的東北電力公司的一艘運(yùn)煤船上。

三菱造船有限公司表示，通過在實際海洋環(huán)境下的運(yùn)行和性能確認(rèn)，三菱造船有限公司將確定作為海洋設(shè)備的系統(tǒng)規(guī)范要求，并將考慮如何使工廠更緊湊。

聲明說，此外，捕獲的二氧化碳可以回收利用，作為一種新的二氧化碳來源，用于加強(qiáng)石油回收過程，或作為合成燃料的原材料，為減少溫室氣體排放做出重大貢獻(xiàn)。

Japanese companies advance plans for world's first marine based carbon capture system

Mitsubishi Shipbuilding Co., Ltd., a part of Mitsubishi Heavy Industries Group, is advancing a project with shipping company "K" Line and classification society Nippon Kaiji Kyokai to conduct test operations and measurements for a small scale ship-based CO2 capture demonstration plant as shipping progresses toward decarbonization.

In April 2018, the International Maritime Organization announced its greenhouse gas strategy and targets to improve CO2 efficiency in shipping. The IMO has set targets that include a 50% cut in the shipping sector's GHG emissions by 2050 compared with 2008.

The project -- Carbon Capture on the Ocean -- is intended to achieve CO2 capture at sea, a world first, Mitsubishi Shipbuilding said in a statement on Aug. 31.

The project is being conducted with support from the Maritime Bureau of Japan's Ministry of Land, Infrastructure, Transport and Tourism, or MLIT, as part of its assistance project for research and development of technological advancements in marine resource development, it said.

The demonstration plant will be manufactured in mid-2021, and following operational tests at the factory, will be installed on board a coal carrier for Tohoku Electric Power Co., Inc. operated by "K" Line, it added.

Through an operational and performance confirmation in an actual marine environment, Mitsubishi Shipbuilding will then determine the system specification requirements as a marine-based device and will also consider how to make the plant more compact, it said.

Further, the captured CO2 can be recycled for use as a new source of CO2 for enhanced oil recovery processes, or as raw material in synthetic fuel, providing a significant contribution to reductions in greenhouse gas emissions, it added.
