据烃加工在线8月17日宣布，自2009年以来，美国炼油厂炼油量每年都在增长，最近一次在2018年达到创纪录的每日1730万桶。然而，EIA根据截至5月的月度炼油运营数据以及对2019年剩余时间的预测，预计2019年炼油量将减少，平均日产量将达到1700万桶。

截至2019年1月1日，美国炼油产能达到创纪录的每日1880万桶。EIA的年度炼油产能报告显示，2019年美国炼油产能不会大幅增加。

6月下旬，费城南部的费城能源解决方案(PES)炼油厂发生爆炸，导致PES停产。PES炼油厂拥有东海岸炼油厂中最大的炼油能力(33.5万桶/天)，但近年来经历了财政压力。在爆炸发生。后的六周内，东海岸地区的炼油厂平均日产量为89.7万桶，比爆炸前六周的平均日产量下降了21.1万桶。

美国炼油厂的运转通常在夏季达到最高点，届时石油产品(尤其是汽油)的需求往往会达到峰值。到目前为止，2019年至8月9日，每周炼油厂的平均日产量为1700万桶，较2018年同期下降1.4%。尽管整体产量较低，但在截至8月2日的一周内，每周炼厂日产量仍超过1800万桶，过去10年仅七次达到这一水平。

EIA在其8月的短期能源展望中预计，2019年炼厂日产量平均将达到1700万桶，而由于炼油产能和利用率的提高，2020年炼厂日产量将增至1760万桶。

US refinery runs expected to decline for first time in a decade

US gross inputs to refineries, also known as refinery runs, have increased each year since 2009, most recently reaching a record high of 17.3 million bpd in 2018. However, based on its monthly refinery run data through May and forecast for the remainder of 2019, the US Energy Information Administration (EIA) expects refinery runs to decline and average 17.0 million bpd in 2019.

US refinery capacity was at a record high of 18.8 million barrels per calendar day as of 1 January 2019. EIA’s annual Refinery Capacity Report shows that US refining capacity will not expand significantly during 2019.

In late June, damage from an explosion at the Philadelphia Energy Solutions (PES) refinery in South Philadelphia led PES to discontinue operations. The PES refinery had the largest refining capacity among East Coast refineries (335 000 bpd), but it experienced financial strains in recent years. In the six weeks since the explosion, refinery runs in the East Coast region (defined as Petroleum Administration for Defense District 1) have averaged 897 000 bpd, a decline of about 211 000 bpd from their averages in the six weeks before the explosion.

US refinery runs typically reach their highest points in the summer, when demand for petroleum products (especially motor gasoline) tends to peak. So far in 2019, weekly refinery runs have averaged 17.0 million bpd through 9 August, or 1.4% lower than during the same period in 2018. Despite their overall lower rate, weekly refinery runs surpassed 18 million bpd in the week ending 2 August – a level achieved only seven times in the past decade.

In its August Short-Term Energy Outlook, EIA expects refinery runs to average 17.0 million bpd in 2019, and EIA expects them to then increase to 17.6 million bpd in 2020 because of increases in both refining capacity and utilisation.
