據ICIS-MRC網站10月5日莫斯科報道，根據烴加工網信息顯示，英國石油公司（bp）宣布計劃在其位于華盛頓州的Cherry Point煉油廠的三個項目上投資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能力。

 

　　預計這些項目將在未來三年內為當地創造300多個就業機會。這包括超過200個建筑崗位，25個工程崗位和大約40個支持崗位。bp目前在華盛頓提供了超過36600個工作崗位。這項投資與bp的目標是一致的，即到2050年或更早的時候，其所有業務的碳排放為零，并在2050年或更早的時候將其銷售產品的碳排放強度降低50%。

 

　　英國石油美國公司董事長兼總裁大衛·勞勒（David Lawler）表示，英國石油公司在Cherry Point的新投資建立在華盛頓州半個世紀的創新基礎上。這將使我們能夠提供低碳能源，同時在運營中創造就業機會并減少排放。

 

　　這項耗資1.69億美元的加氫裂化裝置改進項目(HIP)將提高效率，縮短計劃維護周期，從而減少機組關閉和相關的燃除事件。加氫裂化裝置是煉油廠的“心臟”。在該裝置中，重質油在氫氣存在的情況下經受高溫和高壓，以生產汽油、柴油和航空燃料。

 

　　項目一旦完成后，加氫裂化裝置將消耗更少的氫氣，而氫氣是煉油廠通過天然氣轉化產生的，并產生二氧化碳排放。此外，與現在相比，加氫裂化裝置在煉油廠過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候開始，預計將于2023年完成。

 

　　5500萬美元的冷卻水基礎設施項目（CWI）將加強冷卻水基礎設施，提高利用率，提高能源效率，并相應減少二氧化碳排放。

 

　　就像汽車的散熱器冷卻發動機一樣，煉油廠的冷卻塔通過水的循環為工藝裝置提供冷卻。水在該系統中循環使用，并盡可能多地回收環境熱量。

 

　　冷卻水對安全操作至關重要。該項目將通過使煉油廠全年保持最佳冷卻水溫度來提高可靠性。提高冷卻效率會減少在過程加熱器和公用事業鍋爐中燃燒的輕質碳氫化合物，例如甲烷和乙烷。 冷卻水基礎設施的工程將于今年晚些時候開始，預計將于2023年完成。

 

　　據估計，HIP和CWI項目每年可將Cherry Point運營中的二氧化碳排放量減少約16萬噸，即 7%——相當于減少32,000 多輛美國汽車的排放量。

　　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.
