據(jù)ICIS-MRC網(wǎng)站10月5日莫斯科報(bào)道,根據(jù)烴加工網(wǎng)信息顯示,英國(guó)石油公司(bp)宣布計(jì)劃在其位于華盛頓州的Cherry Point煉油廠的三個(gè)項(xiàng)目上投資2.69億美元,旨在提高煉油廠的效率,減少二氧化碳(CO2)排放,并提高其可再生柴油生產(chǎn)能力。
預(yù)計(jì)這些項(xiàng)目將在未來(lái)三年內(nèi)為當(dāng)?shù)貏?chuàng)造300多個(gè)就業(yè)機(jī)會(huì)。這包括超過(guò)200個(gè)建筑崗位,25個(gè)工程崗位和大約40個(gè)支持崗位。bp目前在華盛頓提供了超過(guò)36600個(gè)工作崗位。這項(xiàng)投資與bp的目標(biāo)是一致的,即到2050年或更早的時(shí)候,其所有業(yè)務(wù)的

碳排放強(qiáng)度降低50%。
英國(guó)石油美國(guó)公司董事長(zhǎng)兼總裁大衛(wèi)·勞勒(David Lawler)表示,英國(guó)石油公司在Cherry Point的新投資建立在華盛頓州半個(gè)世紀(jì)的創(chuàng)新基礎(chǔ)上。這將使我們能夠提供低碳能源,同時(shí)在運(yùn)營(yíng)中創(chuàng)造就業(yè)機(jī)會(huì)并減少排放。
這項(xiàng)耗資1.69億美元的加氫裂化裝置改進(jìn)項(xiàng)目(HIP)將提高效率,縮短計(jì)劃維護(hù)周期,從而減少機(jī)組關(guān)閉和相關(guān)的燃除事件。加氫裂化裝置是煉油廠的“心臟”。在該裝置中,重質(zhì)油在氫氣存在的情況下經(jīng)受高溫和高壓,以生產(chǎn)汽油、柴油和航空燃料。
項(xiàng)目一旦完成后,加氫裂化裝置將消耗更少的氫氣,而氫氣是煉油廠通過(guò)天然氣轉(zhuǎn)化產(chǎn)生的,并產(chǎn)生二氧化碳排放。此外,與現(xiàn)在相比,加氫裂化裝置在煉油廠過(guò)程加熱器中消耗氣體燃料所需的熱量輸入更少。加氫裂化裝置的工程將于今年晚些時(shí)候開(kāi)始,預(yù)計(jì)將于2023年完成。
5500萬(wàn)美元的冷卻水基礎(chǔ)設(shè)施項(xiàng)目(CWI)將加強(qiáng)冷卻水基礎(chǔ)設(shè)施,提高利用率,提高能源效率,并相應(yīng)減少二氧化碳排放。
就像汽車的散熱器冷卻發(fā)動(dòng)機(jī)一樣,煉油廠的冷卻塔通過(guò)水的循環(huán)為工藝裝置提供冷卻。水在該系統(tǒng)中循環(huán)使用,并盡可能多地回收環(huán)境熱量。
冷卻水對(duì)安全操作至關(guān)重要。該項(xiàng)目將通過(guò)使煉油廠全年保持最佳冷卻水溫度來(lái)提高可靠性。提高冷卻效率會(huì)減少在過(guò)程加熱器和公用事業(yè)鍋爐中燃燒的輕質(zhì)碳?xì)浠衔?,例如甲烷和乙烷?冷卻水基礎(chǔ)設(shè)施的工程將于今年晚些時(shí)候開(kāi)始,預(yù)計(jì)將于2023年完成。
據(jù)估計(jì),HIP和CWI項(xiàng)目每年可將Cherry Point運(yùn)營(yíng)中的二氧化碳排放量減少約16萬(wàn)噸,即 7%——相當(dāng)于減少32,000 多輛美國(guó)汽車的排放量。

BP invests at Cherry Point refinery to reduce CO2 emissions
BP announced plans for a USD269 million investment in three projects at its Cherry Point Refinery in Washington state, aimed at improving the refinery’s efficiency, reducing its carbon dioxide (CO2) emissions and increasing its renewable diesel production capability, said Hydrocarbonprocessing.
These projects are expected to create more than 300 local jobs over the next three years. This includes more than 200 construction jobs, 25 engineering jobs and approximately 40 support roles. bp currently supports more than 36,600 jobs in Washington. The investment is aligned with bp’s aims to be net zero across its operations by 2050 or sooner and to reduce the carbon intensity of the products it sells by 50% by 2050 or sooner.
David Lawler, chairman and president, bp America: “bp’s new investment in Cherry Point builds on a half century of innovation in Washington state. It will position us to provide lower carbon energy while creating jobs and reducing emissions in our operations."
The USD169m Hydrocracker Improvement Project (HIP) will improve efficiency and reduce periods of planned maintenance, resulting in fewer unit shutdowns and associated flaring events. The hydrocracker is the “heart” of the refinery. In this unit, heavy oils are subjected to high temperatures and pressure – in the presence of hydrogen – to produce gasoline, diesel and jet fuel.
Upon project completion, the hydrocracker will consume less hydrogen, which is produced at the refinery by conversion of natural gas, producing CO2 emissions. In addition, the hydrocracker will require less heat input from the consumption of gaseous fuel in refinery process heaters than it does today. Work on the hydrocracker will begin later this year and is expected to finish in 2023.
The USD55m Cooling Water Infrastructure Project (CWI) will enhance cooling water infrastructure, allowing for increased utilization, better energy efficiency, and a related reduction in CO2 emissions.
Just as a radiator in a car cools the engine, cooling towers in the refinery enable cooling for process units through circulation of water. Water is recycled in this system, and as much ambient heat as possible is recovered.
Cooling water is vital to safe operations. This project will improve reliability by enabling the refinery to maintain an optimum cooling water temperature year-round. Increasing efficiency in cooling produces fewer light hydrocarbons, such as methane and ethane, that are combusted in process heaters and utility boilers. Work on the cooling water infrastructure will begin later this year and is expected to be completed in 2023.
The HIP and CWI projects are together estimated to reduce CO2 emissions from operations at Cherry Point by approximately 160,000 tons per year, or seven percent – equivalent to taking more than 32,000 US cars2 off the road.
