TAQA, JERA collaborate on cogen plant for power to Jubail petrochemical complex (Saudi Arabia)
Abu Dhabi National Energy Company PJSC (TAQA) and JERA Co., Inc announced the successful financial closing of Najim Cogeneration Company Limited, a new industrial steam and electricity cogeneration plant that will produce electricity and steam for a petrochemical complex located in Jubail in the Eastern Province of the Kingdom of Saudi Arabia.
Utilizing pilot plant operations for new chemical process technology development: A roadmap to scale up success and commercial plant safety
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.
How important is connected pipework to PSVs?
The purpose of this article is to explain additional process considerations for pipework connected to PSVs, such as isolation valves, layout, orientation, forces and moments.
Review steam system designs to accelerate chemical industry decarbonization
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.
Best practices for proper alarm management
Process alarms are critical safeguards put into place on operating units to enable operators to avoid incidents that impact a company’s safety, reliability and bottom line. It is absolutely essential to any safe facility operation that alarms are properly managed and utilized to address real and consequential operational issues before they become incidents.
Utilize a hydrogen reactions lab to optimize renewable fuels processing
Leading technology developers in the refining space are utilizing various catalysts to enhance the adjusted reaction chemistry, but this does not directly address how to optimize hydrogen utilization for the hydrodeoxygenation and isomerization/cracking processing steps. To ensure the right equipment outlay and calibration for these hydrogenation applications, replicating the process in a lab setting can help identify efficiencies and yield improvements for a fraction of the cost that a refiner would incur attempting to achieve that optimization through modifications at commercial scale.
Case study: Developing mildew-resistant coatings on ethanol tanks
Scientists from the authors’ company determined how best to combat persistent black mildew on aboveground storage tanks by first using a novel strategy to identify it. This discovery led to the identification of coating formulations with superior capacity to prevent mildew growth. The scientists proved the performance of the coatings by conducting field tests involving painting sample patches onto an ethanol storage tank.
Refinery/petrochemical makeup water treatment: A general guide for technical personnel—Part 1
New personnel are often confronted with challenges that require knowledgeable and quick action, which they may have difficulty providing without thorough training. A very important—and sometimes overlooked—unit operation within these facilities is makeup water treatment for steam generators and other processes. Many cases have been documented in which makeup system upsets have led to boiler tube failures that partially or completely shut down unit processes. Parts 1 and 2 (September 2024) of this article serve as a guide for those employees who may be on a steep learning curve when it comes to makeup system understanding.
Zero liquid discharge: A stepping stone to water sustainability—Part 1
Among the available technologies of wastewater treatment to recover reusable water, zero-liquid discharge (ZLD) has become the most frequently used term in oil and gas refineries and petrochemical plants. It has been effectively used in the treatment of brine to maximize the recovery of freshwater or recycled water and to recover salt and other chemicals that are used in other industries.
