bp投资Cherry Point炼厂以减少碳排放

  据ICIS-MRC网站10月5日莫斯科报道,根据烃加工网信息显示,英国石油公司(bp)宣布计划在其位于华盛顿州的Cherry Point炼油厂的三个项目上投资2.69亿美元,旨在提高炼油厂的效率,减少二氧化碳(CO2)排放,并提高其可再生柴油生产能力。
 
  预计这些项目将在未来三年内为当地创造300多个就业机会。这包括超过200个建筑岗位,25个工程岗位和大约40个支持岗位。bp目前在华盛顿提供了超过36600个工作岗位。这项投资与bp的目标是一致的,即到2050年或更早的时候,其所有业务的碳排放为零,并在2050年或更早的时候将其销售产品的碳排放强度降低50%。
 
  英国石油美国公司董事长兼总裁大卫·劳勒(David Lawler)表示,英国石油公司在Cherry Point的新投资建立在华盛顿州半个世纪的创新基础上。这将使我们能够提供低碳能源,同时在运营中创造就业机会并减少排放。
 
  这项耗资1.69亿美元的加氢裂化装置改进项目(HIP)将提高效率,缩短计划维护周期,从而减少机组关闭和相关的燃除事件。加氢裂化装置是炼油厂的“心脏”。在该装置中,重质油在氢气存在的情况下经受高温和高压,以生产汽油、柴油和航空燃料。
 
  项目一旦完成后,加氢裂化装置将消耗更少的氢气,而氢气是炼油厂通过天然气转化产生的,并产生二氧化碳排放。此外,与现在相比,加氢裂化装置在炼油厂过程加热器中消耗气体燃料所需的热量输入更少。加氢裂化装置的工程将于今年晚些时候开始,预计将于2023年完成。
 
  5500万美元的冷却水基础设施项目(CWI)将加强冷却水基础设施,提高利用率,提高能源效率,并相应减少二氧化碳排放。
 
  就像汽车的散热器冷却发动机一样,炼油厂的冷却塔通过水的循环为工艺装置提供冷却。水在该系统中循环使用,并尽可能多地回收环境热量。
 
  冷却水对安全操作至关重要。该项目将通过使炼油厂全年保持最佳冷却水温度来提高可靠性。提高冷却效率会减少在过程加热器和公用事业锅炉中燃烧的轻质碳氢化合物,例如甲烷和乙烷。 冷却水基础设施的工程将于今年晚些时候开始,预计将于2023年完成。
 
  据估计,HIP和CWI项目每年可将Cherry Point运营中的二氧化碳排放量减少约16万吨,即 7%——相当于减少32,000 多辆美国汽车的排放量。

  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.
