Special Focus: Plant Safety and Environment

FTO: An enabling emission control technology for petrochemical plant expansions
Armstrong, P., Predatsch, E., Selas-Linde North America

For the petrochemical industry, the U.S. Gulf Coast (USGC) has the locational advantage of proximity to cheap feedstock, and to an abundance of pipeline infrastructure and terminals for export markets.

Protect your assets and our environment
Ruitenberg, R., Nalco Water, an Ecolab company

Process cooling usually comprises the largest part of the water footprint of a refinery or petrochemical plant.

Optimize flare gas recovery system design to reduce emissions
Lu, S.-G, CTCI, Corp.

Emissions from flares worsen air quality and produce waste gas. A flare gas recovery system is designed to facilitate CO2 reduction.

Achieve process safety, asset integrity and reliability with an integrated HAZOP study
Chakravorty, S. L., Independent Consultant

Abnormal situations in refining and petrochemical plant operations can interfere with plant reliability and efficient operations, especially for highly complex processes.

Reboiler pinch: An approach to optimize flare system design during FEED
Amin, H., Saudi Aramco; Dhote, P., Kanade, S., Siemens

A process plant’s pressure relief and flare systems are critical safety elements.

When toxic risk cannot be prevented, mitigate consequences of H2S with fluid curtains
Benintendi, R., Megaris, Ltd.

Toxic risk preferably should be controlled according to Kletz’s inherent safety principle, which consists of some preventive golden rules, notably minimize, substitute, moderate and simplify.

Refining Technologies

Shape the refinery of the future through integration—Part 2
Maiti, S. N., SNC-Lavalin Inc.

Part 1 of this article, which appeared in the September issue, discussed various aspects of evaluating options that enable an existing refiner to make investment decisions to optimally diversify into petrochemicals through integration. Part 2 will detail a case study that illustrates the synergies of refinery-petrochemical integration through a propylene recovery unit from an FCC-based refinery, as well as financial, configuration and sensitivity analyses.

Catalysts

Maximize FCC product yields with a specialty catalyst formulation
Kukade, S., Kumar, P., Ramachandrarao, B., Hindustan Petroleum Green R&D Center, Hindustan Petroleum

Fluid catalytic cracking (FCC) is one of the most important conversion processes used in petroleum refineries and has been in use for more than 75 yr.

Process Control, Instrumentation and Automation

Reduce gasoline blending giveaway with inline blending and online analyzers
Curcio, E., Barsamian, A., Refinery Automation Institute, LLC

With best available technology, how much practical reduction in giveaway can be achieved, with the caveat that there is no such thing as “zero error” in value measurements? Also, can those numbers change if inline blending is used? This article seeks to answer both questions.

Valves, Pumps and Turbomachinery

Mitigate transient/hydraulic surge in liquid pipelines with nozzle check valves
Khiani, G. N., GAPV Inc.

Liquid pipelines often come across hydraulic transients, which can damage pipelines and associated equipment (i.e., pumps, valves, stations, etc.).
