石油设备网讯 据普氏能源资讯2019年4月1日纽约报道，周一来自标准普尔全球普氏能源资讯的分析显示，由于加拿大、欧洲和中国的计划工作抵消了美国计划维修工作的完成，上周全球炼油利润率小幅走高。
在美国西海岸，炼油利润率再次上升，由于该地区计划外的运行中断继续，炼油利润率将进一步上升。
普氏能源资讯的利润率数据显示，截至3月29日的一周里，阿拉斯加北斜坡裂缝利润率平均为15.09美元/桶，为2018年10月以来的最高水平。
焦化利润率也有所上升，美国本土企业THUMS的焦化利润率最近一周平均为17.89美元/桶，高于一周前的14.69美元/桶。
普氏能源资讯的利润率数据反映了原油净价与现货价格之间的差异。净回值基于原油产量，而原油产量是通过把普氏精炼产品价格评估应用于特纳、梅森公司(Turner, Mason & Co.)设计的产量公式计算出来的。
根据标普普氏全球能源资讯分析部门的数据，预计在截至4月5日的一周内，大约15.6万桶/天的美国西海岸流体催化裂化产能将停产。消息人士称，雪佛龙公司位于加州埃尔塞贡多的日产量为26.9万桶的炼油厂周一早些时候开始停产，导致日产7.38万桶的流体催化裂化装置意外停产，这一数字可能还会增加。
普氏分析部门估计，总体而言，2019年第二季度美国原油蒸馏装置的利用率将上升，因为停机量将从第一季度的每日165.8万桶降至每日124.7万桶。

Global refinery margins strengthen, supported by planned work
Global refinery margins ticked higher as planned work in Canada, Europe and China offset the completion of planned maintenance in the US, analysis from S&P Global Platts showed Monday.
On the US West Coast, margins rose again, gaining further traction as unplanned outages continued in the region.
The Alaska North Slope cracking margin averaged $15.09/b in the week that ended March 29, the highest since October 2018, Platts margin data show.
Coking margins also increased, with indigenous California THUMS coking margins averaging $17.89/b in the most recent week, up from $14.69/b a week earlier.
Platts margin data reflects the difference between a crude's netback and its spot price. Netbacks are based on crude yields, which are calculated by applying Platts refined product price assessments to yield formulas designed by Turner, Mason & Co.
about 156,000 b/d of USWC fluid catalytic cracking capacity was forecast to be offline in the week ending April 5, according to S&P Global Platts Analytics data. That will likely increase with a unplanned outage of the 73,800 b/d fluid catalytic cracking unit at Chevron's 269,000 b/d El Segundo, California, refinery that began earlier Monday, according to sources.
Overall, second-quarter 2019 US crude distillation unit utilization will rise as outages drop from 1.658 million b/d in the first quarter to 1.247 million b/d, Platts Analytics estimates show.
