據(jù)烴加工網(wǎng)站12月15日?qǐng)?bào)道，霍尼韋爾宣布與得克薩斯大學(xué)奧斯汀分校（UT Austin）達(dá)成一項(xiàng)協(xié)議，實(shí)現(xiàn)以較低成本捕獲發(fā)電廠和重工業(yè)排放的二氧化碳。

霍尼韋爾將利用得克薩斯大學(xué)奧斯汀分校專有的先進(jìn)溶劑技術(shù)開(kāi)發(fā)針對(duì)電力、鋼鐵和水泥等工廠的碳捕獲新解決方案，以降低新設(shè)備或現(xiàn)有設(shè)備中燃燒煙氣產(chǎn)生的碳排放。該解決方案為這些部門(mén)提供了有效手段，幫助其滿足監(jiān)管要求和可持續(xù)發(fā)展目標(biāo)。

霍尼韋爾已承諾到 2035 年在其運(yùn)營(yíng)的設(shè)施中實(shí)現(xiàn)碳中和。

與得克薩斯大學(xué)奧斯汀分校的許可協(xié)議擴(kuò)展了霍尼韋爾領(lǐng)先的碳捕集技術(shù)組合。霍尼韋爾通過(guò)其專業(yè)的碳解決方案，已經(jīng)捕獲1500萬(wàn)噸/年二氧化碳，將其存儲(chǔ)或進(jìn)行利用。霍尼韋爾稱，公司有能力通過(guò)其在全球?qū)嵤┑捻?xiàng)目捕獲 4000萬(wàn)噸/年二氧化碳。

得克薩斯大學(xué)奧斯汀分校的專利解決方案采用先進(jìn)溶劑，小規(guī)模設(shè)備，可以在低成本投入的情況下，高效捕獲二氧化碳。對(duì)于典型的發(fā)電廠（650 MW 容量），使用該溶劑碳捕集技術(shù)每年可捕集約340噸二氧化碳，相當(dāng)于每年從道路上移除近735,000輛汽車。

該二氧化碳捕獲技術(shù)可用于現(xiàn)有設(shè)備或新建設(shè)備。在該過(guò)程中，二氧化碳被吸收到胺溶劑中，然后被送到汽提塔，實(shí)現(xiàn)二氧化碳與溶劑分離，分離出的二氧化碳經(jīng)壓縮后封存地下或使用。

據(jù)國(guó)際能源署稱，2020年，全球 CCUS 項(xiàng)目捕獲和儲(chǔ)存/使用的二氧化碳為 4000噸。為了與 IEA 可持續(xù)發(fā)展愿景保持一致，即：將全球溫度上升限制在 1.65℃以下，CCUS 項(xiàng)目容量必須增加 20 倍以上，即到2030 年需要捕獲 84000噸二氧化碳。

Honeywell, University of Texas to collaborate on new CCS technology

Honeywell announced an agreement with The University of Texas at Austin that will enable the lower-cost capture of CO2 emissions from power plants and heavy industry.

Honeywell will leverage UT Austin's proprietary advanced solvent technology to create a new offering targeted at power, steel, cement and other industrial plants to lower emissions generated from combustion flue gases in new or existing units. The solution provides these sectors with an additional tool to help meet regulatory requirements and sustainability goals.

Honeywell has committed to achieve carbon neutrality in its operations and facilities by 2035. 

The licensing arrangement with UT Austin expands Honeywell's leading carbon capture technology portfolio. Today, 15 MMtpy of CO2 is being captured and used in storage/utilization applications through Honeywell's CO2 Solutions process expertise. Honeywell currently has the capacity to capture 40 MMtpy through its installed projects worldwide.

UT Austin's patented solution utilizes an advanced solvent, which enables CO2 to be captured at a lower cost through greater efficiency using smaller equipment. For a typical power plant (650 MW capacity), applying advanced solvent carbon-capture technology would enable the capture of about 3.4 MM tons of CO2 annually, equivalent to removing nearly 735,000 cars from the road each year.

This CO2 removal technology can be retrofitted within existing plants or included as part of a new installation. In this process, CO2 is absorbed into an amine solvent and then sent to a stripper where CO2 is separated from the solvent. This CO2 is then compressed for geological sequestration or used for other purposes. 

In 2020, CCUS projects worldwide were capturing and storing/using 40 MM metric tpy of CO2, according to the International Energy Agency (IEA). In order to align with the IEA Sustainable Development Scenario, which demonstrates a pathway to limit global temperature rise by less than 1.65o C, CCUS project capacity must increase more than 20 times to enable capture of 840 MM metric tpy of CO2 by 2030.
