The vacuum residue fraction of petroleum is one of the most complex mixtures of compounds known, one which continues to defy comprehensive analysis. The combination of complexity, diversity, and aggregation of the asphaltenes has enormous implications for upgrading reactions and phase behaviour...

Showa Denko owns and operates a large Ethylene plant in Oita, Japan. Depending on the economic environment, plant objective is a combination of Energy Efficiency and Production Capacity. In order to achieve these objectives, Showa Denko had contracted Yamatake and Honeywell to design, configure and...

Borealis' cracker in Stenungsund, Sweden was a very early adopter of APC for olefin plants. Part of Exxon's early 80's roll out of APC based on Honeywell's PMX process computer on top of a TDC2000 DCS the plant got over a few years state of the art furnace, compressor and distillation control. In...

ABSTRACT A significant amount of work has transpired over the past several years in generating consensus-based standards that include ASME PCC-2 and ISO 24817 for developing composite repair systems. The intent in developing these standards has been to provide industry with guidelines for designing...

Abstract: Corrosion, blockage, fouling, and mechanical/thermal overload are the key degradation mechanisms that operators need to control to avoid premature failure of their aluminum plate fin heat exchangers. The paper will describe these degradation mechanisms as well as how to incorporate finite...

Reliable operation of induced-draft fans on ethylene furnaces is critical to maintaining plant output capacity. Achieving this requires close attention to numerous issues during specification, design, installation, and monitoring in operation. This paper will examine recommended practice pertaining...

The use of organosulfur compounds in steam cracking furnaces to produce ethylene and propylene is a universal practice to essentially prevent carbon monoxide (CO) and minimize coke formation. While there is agreement that this decreases the level of CO in the product gas, there is seemingly...

In May 2008, the EPA established new 8-hour primary and secondary ozone standards equal to 0.075 ppm. This represented a significant tightening over the previous 0.08 ppm 8-hour standard. However, a little more than a year later, in September 2009, EPA announced that it was going to reconsider the...

Utilization of Equipment Health Management system tools has allowed end users to monitor, protect and manage the critical rotating machinery in an Ethylene Plant. This paper will present an equipment health management system architecture, hardware and software components that provide performance...

As this abstract is written, there will be flare system emission testing in a controlled environment underway that will likely pave the way for new VOC control measures on all flare systems in the US. The TCEQ (Texas Commission on Environmental Quality) sponsored testing held in Q4 2010, will...
