Operators in oil and gas manufacturing facilities have long depended on human machine interfaces (HMI) to offer a visual summary of process systems that simplifies the monitoring of crucial status and control data. A well-crafted graphical user interface enhances situational awareness, decreases workload and empowers operators to oversee the entire process, facilitating their focus to quickly address any abnormal scenarios.

Hydrocarbon Processing sat down with Tobias Nitzsche, Global Cyber Security Practice Lead, ABB, to discuss the European Union’s (EU’s) NIS2 Directive—the EU-wide legislation on cybersecurity—and how it will affect the hydrocarbon processing industry.

Nothing will impede a successful plant turnaround like improper planning. One aspect of this planning is effective inventory management, and the keys to achieving this are properly identifying and communicating maintenance needs.

To demonstrate a new chemical process technology (flowsheet, raw materials, product) or improve an existing one, pilot plants are designed and operated at a scale between laboratory benchtop and commercial scale—often with specific goals for operability, product quality, economics and process safety. Identifying where potential safety, technical risks or uncertainties may occur is always a key goal in evaluating a new process.

Industrial steam systems range from simple systems comprising a low-pressure single steam user to a complex system with multiple pressure levels, multiple generators and multiple users integrated with an onsite cogeneration facility. This article will present the typical CO2 emissions estimates for chemical and petrochemical facilities and describe options available to reduce these emissions through additional heat integration, fuel switching, and the use of heat pumps and electric boilers. 

In one recent project for a customer based in Asia, the authors’ company suggested the combination of distillation and crystallization techniques to obtain high-quality purified benzoic acid. Encouraged by the successful startup of this processing train, the customer began to schedule a second project. The authors’ company was asked to optimize the purification process to improve cost and operational efficiencies. The two existing columns, which remove lights and heavies, respectively, from the crude benzoic acid feedstock were investigated to identify key opportunities. The feasibility study based on the feed composition confirmed that the existing columns could be converted into a single dividing wall column (DWC).
