据MRCHUB网站4月12日莫斯科报道，近日，EIA在其网站上表示，自2010年以来，美国的乙烷消费量每年都在增长，目前美国的乙烷消费量超过了航空燃料或丙烷。
根据EIA 2022年3月《石油供应月刊》(Petroleum Supply Monthly)的数据显示，2021年乙烷的消费量增加了5万桶/天。据EIA预测，到2023年，美国的乙烷消费量将再增加34万桶/天。
自2010年以来，由于对乙烷作为石化原料的需求不断增长，美国乙烷的年消费量每年都在增加。乙烷主要作为石化原料生产乙烯，而乙烯又用于制造塑料和树脂。
过去两年，由于乙烯裂解能力的提高，国内乙烷消耗量有所增加。相比之下，由于新冠疫情期间旅行量减少，过去两年中大多数其他石油产品的消费量减少了。
尽管去年2月中旬美国墨西哥湾遭遇冬季风暴，导致超过三分之一的美国乙烯裂化产能停产，但2021年美国乙烷消费量仍在增长。由于美国大约90%的乙烷消费集中在墨西哥湾沿岸，风暴中断导致2021年2月的乙烷消费量减少了65.5万桶/天。尽管出现了这种下降，但2021年下半年两种新的乙烯裂解装置增加的产能推动了2021年乙烷消费量的整体增长。
据EIA预计，2022年和2023年美国的乙烷日均消费量为210万桶，因为最近在宾夕法尼亚州的Monaca完成了另一个乙烯裂解装置，预计将增加9.6万桶/天的乙烷原料产能，而现有的乙烯裂解装置将以更高的利用率运行。

Ethane to outpace increase in all other US petroleum product consumption through 2023
Consumption of ethane has grown every year since 2010 in the US, and more ethane is now consumed in the country than either jet fuel or propane, said EIA on its site.
Consumption of ethane, which the EIA estimates using product supplied, grew by 50,000 bpd in 2021, according to data from its March 2022 Petroleum Supply Monthly. The EIA forecasts that by 2023, US consumption of ethane will grow by another 340,000 bpd.
Annual US ethane consumption has increased in every year since 2010 because demand for ethane as a petrochemical feedstock has grown. Ethane mainly serves as a petrochemical feedstock to produce ethylene, which is used to make plastics and resins.
Domestic ethane consumption over the past two years has increased due to increased ethylene cracking capacity. In contrast, consumption of most other petroleum products has decreased these past two years as a result of less travel during the COVID-19 pandemic.
US ethane consumption grew in 2021 despite the mid-February winter storm on the US Gulf Coast, which took more than one-third of US ethylene cracking capacity offline. Because about 90% of US ethane consumption is concentrated along the Gulf Coast, storm disruptions reduced ethane consumption by 655,000 bpd in February 2021. Despite this drop, the additional capacity from two new ethylene crackers during the second half of 2021 contributed to an overall increase in ethane consumption in 2021.
The EIA expects U.S. ethane consumption to average 2.1 MMbpd in both 2022 and 2023 because another ethylene cracker was recently completed in Monaca, Pennsylvania, which will add an estimated 96,000 bpd of ethane feedstock capacity, and existing ethylene crackers should operate at higher utilization rates.
