Overview
The Delaware City Refinery is a major petroleum processing facility located in Delaware City, Delaware, United States. It operates as a key asset within the Mid-Atlantic energy infrastructure, serving as a critical node for fuel distribution to the regional market. The refinery is currently owned by the Delaware City Refining Corporation, which functions as a subsidiary of PBF Energy, a prominent independent energy company. PBF Energy manages the day-to-day operations, leveraging the site's strategic location along the Delaware River to optimize logistics for both crude oil intake and refined product export.
Commissioned in 1956, the refinery has maintained continuous operational status for several decades, adapting to shifting energy demands and technological advancements in crude oil processing. The facility processes a mixed fuel source, handling various crude blends to produce a diverse range of petroleum products including gasoline, diesel, jet fuel, and petrochemical feedstocks. Its long history reflects the evolution of the American refining industry, transitioning from early atmospheric distillation methods to more complex conversion and treatment units to maximize yield and product quality.
The plant boasts a significant throughput capacity of 210,000 barrels per day, which equates to approximately 33,000 cubic meters per day. This volume places it among the larger refineries in the Northeastern United States, providing substantial fuel supply to the tri-state area of Delaware, Pennsylvania, and New Jersey. The operational scale supports a workforce of around 570 employees, contributing to the local economy through direct employment and ancillary service contracts. The refinery's continuous operation underscores its reliability and importance to regional energy security.
The physical footprint of the Delaware City Refinery is extensive, covering a land area of 5,000 acres. This large parcel of land accommodates the intricate network of distillation towers, storage tanks, processing units, and utility systems required for large-scale refining. The site's layout allows for efficient material flow from the riverfront terminals, where crude oil is unloaded, through the various processing stages, and finally to storage and distribution points. The substantial land area also provides room for future expansion or retrofitting of units to accommodate changing crude qualities and product specifications.
Ownership History and Operational Timeline
The Delaware City Refinery has undergone significant ownership transitions since its commissioning in 1956. The facility is currently operated by PBF Energy, which acquired the asset through its subsidiary, Delaware City Refining Corporation. The refinery’s operational history reflects broader trends in the global energy sector, including mergers, divestitures, and strategic acquisitions by major petroleum companies.
Early Ownership and Corporate Transitions
The refinery was initially commissioned in 1956 under the ownership of Getty Oil. Over the subsequent decades, the facility changed hands multiple times. In 1984, Texaco assumed ownership of the Delaware City Refinery, integrating it into its broader refining network. This period marked a phase of operational stability under a major integrated oil company.
In 1988, the refinery was acquired by Star Enterprises, signaling a shift toward more specialized refining operations. Star Enterprises managed the facility for a decade, during which time the refinery likely underwent various operational adjustments to remain competitive in the mid-Atlantic energy market.
Later Acquisitions and Current Operation
Motiva Enterprises took over the Delaware City Refinery in 1998, continuing the trend of corporate consolidation in the refining sector. Motiva, a joint venture involving ExxonMobil, Chevron, and ConocoPhillips, brought significant resources and strategic focus to the facility.
In 2004, the refinery became part of Premcor, which was later acquired by Valero Energy in 2009. This acquisition integrated the Delaware City Refinery into one of the largest refining networks in the United States, enhancing its operational scale and market reach.
PBF Energy assumed ownership of the refinery in 2010, marking the beginning of its current operational era. Under PBF Energy, the Delaware City Refinery continues to operate with a total throughput capacity of 210,000 barrels per day, employing approximately 570 individuals. The facility remains a key component of PBF Energy’s refining portfolio, contributing to the energy infrastructure of Delaware and the broader Mid-Atlantic region.

Technical Specifications and Infrastructure
The Delaware City Refinery operates with a total throughput capacity of 210,000 barrels per day, equivalent to 33,000 cubic meters per day. The facility processes mixed fuel sources, with a specific technical emphasis on handling heavy sour crude oil. This crude selection strategy is reflected in the refinery’s Nelson Complexity Index of 13.6, a metric that quantifies the diversity of processing units relative to the volume of crude processed. A higher complexity index indicates a greater ability to convert heavier, more viscous crude fractions into high-value refined products, such as gasoline and diesel, compared to simpler atmospheric distillation setups.
Key Processing Units and Technology
The refinery’s infrastructure includes a fluid coker, a critical unit for converting residual heavy oil into lighter products and petcoke. The fluid coker is complemented by Fluid Catalytic Cracker (FCC) regenerator wet gas scrubbers, which are essential for managing emissions and optimizing the catalytic cracking process. These wet gas scrubbers help remove impurities from the regenerator flue gas, enhancing the overall efficiency of the FCC unit. The integration of these technologies allows the Delaware City Refinery to effectively handle the specific characteristics of heavy sour crude, maximizing yield and product quality.
Hydrogen Plant and Strategic Assets
In a significant move to optimize its asset base, the refinery’s hydrogen plant was sold to Air Products in 2020. The transaction was valued at 530 million. This sale reflects a broader industry trend where refineries evaluate the strategic value of ancillary units, such as hydrogen production, which can be operated as standalone facilities or integrated into broader industrial hydrogen networks. The hydrogen plant plays a crucial role in the refining process, particularly for hydrotreating and hydrocracking units, which are vital for removing sulfur and other impurities from the heavy sour crude processed at the facility.
Community Impact and Economic Significance
The Delaware City Refinery serves as a pivotal economic engine for Delaware City, Delaware, with its operational status directly influencing local employment and municipal revenue. The facility, operated by PBF Energy through its subsidiary Delaware City Refining Corporation, employs around 570 individuals, representing a significant portion of the local workforce. The refinery's economic footprint is characterized by its resilience through major operational shifts, most notably the closure and subsequent restart that defined the early 2010s.
Operational Volatility and Economic Recovery
The refinery experienced a significant period of volatility between 2009 and 2011. The initial closure in 2009 created immediate economic uncertainty for the community, affecting both direct employees and local service providers. The decision to restart operations in 2011 marked a critical turning point for the local economy. This restart stabilized the employment base and restored the steady flow of tax revenues to municipal and county budgets. The return to full operational capacity, with a total throughput of 210,000 barrels per day (33,000 m3/d), reinforced the refinery's role as a primary industrial asset in the region.
