Eliminating H2S & SO2 Emissions at SRU, Coker and Other Sulfur Handling Units of Refineries

Sean Kirkpatrick - Vapor Point, LLC

Description

Vapor Point applies high efficiency liquid scrubbing systems to eliminate Hydrogen Sulfide (H2S), Sulphur Dioxide (SO2) other Sulfur Species as well as other Hazardous Air Pollutants (HAPs) and Volitale Organic Compounds (VOCs). Specially designed temporary vessels for liquid and vapor phase product management have also been developed and are key elements in some applications. These control system concepts and resulting proven processes were developed with input from refining personnel who needed alternative technologies that would offer operational flexibility eliminating the various sulfur contaminates. The vapor phase emission control systems and specially designed process vessels have met the needs of the refining industry with numerous field implementations.

“4G” Combustion Technology for Flares

Chris Ferguson - Honeywell

Description

As flare regulations tighten there has been increased emphasis on monitoring and controlling flaring. While there have been advances in steam control systems and plume monitoring systems there has not been a fundamental change in flare combustion technology for decades. This presentation introduces “4G” combustion technology which changes the paradigm of currently available “3G” flare combustion technology, and sets the bar for the next generation of flare design.

Ultra-Low Steam Consumption, High Capacity Smokeless Flare

Clayton Francis - Zeeco

Description

This paper will introduce the technology behind, test data for, and industry challenges addressed by a new Ultra-Low Steam Consumption, High Capacity Smokeless Flare design developed by Zeeco, Inc. This flare technology is designed to further improve flaring efficiency and reduce steam consumption while continuing to meet the EPA Code of Federal Regulations, Chapter 1, Subchapter C, Part 63, Subpart CC requirements. We will focus on how the design addresses known industry challenges in high capacity, low steam consumption flaring, such as needing the ability to operate at low flare gas pressure since many applications have a maximum flare gas pressure at the flare tip of 3 psig. The paper will detail how this new design can achieve as low as 0.17 lbs. steam / lbs. flare gas at 20% of maximum flow rate, with the maximum flow rate achieved at a flare gas pressure of 3 psig. The above data is based upon a 5 mph wind with less than Ringlemann 1 opacity and a flare gas that is 100% propylene. For smokeless operation with propylene, other current steam assisted flare designs require approximately 0.5 lbs. steam / lbs. flare gas and / or a much higher flare gas pressure at maximum flaring capacity. Ultra-Low Consumption Steam Assisted Flaring is very important since any reduction in the required steam flow rate saves not only money, but also reduces the emissions produced from the production of the required higher steam flows. A key feature of this technology is that the air and steam mixture leave the flare at the same elevation as the flare tip exit, meaning no pre-mixing of air into the flare stream. Other current industry designs mix the air and steam with the flare gas prior to exiting the flare tip, negatively impacting the NHVcz according to the new calculation parameters required by MACT CC. Zeeco’s design more efficiently mixes the steam and air together and then mixes the resulting stream with the flare gas, creating a final mixture with a significantly increased volume of air. When the resulting mixture interacts with the flare gas at the tip exit, the increased air volume is readily available for combustion, meaning the flare is less likely to smoke. Since the design more efficiently mixes the air and steam together, less steam is required to achieve smokeless operation. Furthermore, the inherent efficiency of the mixing delivers a design less dependent upon using flare gas pressure to achieve smokeless operation. The flare can successfully operate at lower gas pressures at maximum flow rate.

The Final Flare Requirements – Latest Update on the Refinery Sector Flare Rule

Troy Boley - Spectrum Environmental Solutions, LLC

Description

The experts at Spectrum Environmental Solutions, LLC (Spectrum) have been involved with a wide variety of industrial flare related issues within the petroleum and petrochemical related industry sectors. This presentation will lay a solid foundation for the rest of the conference presentation day as Spectrum will highlights the recent Federal flare rules specifically promulgated for the petroleum refinery sector. The intent will also be to provide the attendees with an understanding of the most likely flare improvement requirements anticipated by industry within future rulemaking for ethylene and chemical facility flares.

Reduce Turnaround Duration By Eliminating Flare/Flare Gas Recover Using New Scrubber Technology

Jim Woodard - Vapor Point LLC

Description

The refining industry is challenged with the development of alternative technologies to control hazardous and regulated emissions such as Hydrogen Sulfide and Total VOC compounds.  FederalAgencies, through rule promulgation and Consent Decree, have emphasized a highlighted effort to minimize flare usage as a control device.  The current rule promulgation of NSPS subpart Ja, RefineryMACT, and the Refinery Technology Rule each will provide challenges to perform de-inventory and decontamination phases of turnarounds in a timely manner.  The direct impact of regulatory action is on the shoulders of those responsible for the planning, execution, and management of turnaround activities.  Vapor Point will present case histories on projects at multiple refineries and multiple process units requiring various control requirements.  Presentation will demonstrate very common challenges that refiners face under the new EPA regulations and solutions that have been successfully deployed in the field with the new scrubber technology package.
