An Incremental, Multi-Technology Approach to Retrofitting Existing Pulverized Coal Power Plants for Carbon Capture

Mar 23, 2010

David C. Miller

Global climate models indicate that acting rapidly to reduce carbon dioxide emissions will provide greater benefits to the environment than delaying action; however, new technologies, currently under development, may be significantly less costly than those currently ready to be deployed. This...

Marine Boil off Gas Recovery Improvement by Performing Slow Loading at Bontang LNG Terminal

Mar 23, 2010

Johan Anindito Indriawan

During LNG loading operation at Bontang LNG Terminal, the LNG vapor called Marine Boil Off Gas (MBOG) is always generated. Ideally, this vapor should be recovered to shore as an additional fuel gas supply or to be re-Liquefied. Nevertheless, due to some constraints, only around 23-37% of the total...

Oxygen Enhanced Reforming: A Low Capital Cost Retrofit Solution to Debottleneck H2 Plant Production Capacity

Mar 23, 2010

Gregory J. Panuccio

Stricter environmental emissions regulations and increased processing of severe crude oil fractions is causing H2 demand to grow across the refining industry. Costs associated with new H2 plant construction have been escalating, so refiners are increasingly looking for low capital cost retrofit...

Possible Solutions for Reducing NOx and SOx Emissions from Large Cargo Ships

Mar 23, 2010

Reggie Zhan

In an attempt to curb air pollution from the shipping industry, the U.S. Environmental Protection Agency (EPA) proposed two new sets of standards in July 2009, which requires ships that have compression-ignition engines with a capacity of 30 liters or more per cylinder in U.S. waters to cut...

Equilibrium and Kinetic Studies Carbon Dioxide Capturing on Ca-Based Sorbents

Mar 23, 2010

Jorge Pena Lopez

The increase of atmospheric carbon dioxide concentrations in recent years is well documented. Its potential link to an earth wide greenhouse-like effect has led recently to tighter regulations on carbon dioxide emissions from various industrial sources. One of the most common emitters is the fossil...

Ethylene Unit Hydrocarbon Release and Fire, Sunoco Marcus Hook, PA Refinery

Mar 23, 2010

Arthur Jensen

At approximately 10:15 p.m. on Sunday, May 17, 2009, there was a sudden and large hydrocarbon release from a main process pipe in the Ethylene Unit at the Sunoco Marcus Hook, Pennsylvania Refinery. The release found an ignition source at an operating process furnace within 2 seconds, resulting in a...

Flexibilities of LNG Storage in Lined Rock Cavern (LRC) with High Operating Pressure

Mar 23, 2010

The natural gas consumption is expected to grow significantly in the next decades. The need for building LNG import terminals with significant storage capacity is quite often a critical aspect due to restriction of land in the area of interest and environmental constraints. A new concept for the...

A Unified Model for LNG Pool Spread and Vapor Dispersion: Is Wind Scooping Really a Factor?

Mar 23, 2010

Filippo Gavelli

U.S. regulations for the siting of LNG facilities require LNG spills to be collected into impounded areas and the impoundments must be sited in such a way that LNG vapor clouds formed as a result of defined spills dissipate to below ½ LFL before reaching a property line that can be built upon [1]...

Enhancing Post-Combustion CO2 Capture in Power Plant – A Catalytic Approach

Mar 23, 2010

Reynolds A. Frimpong

Improved solvent reaction kinetics and carbon capacity continue to be a major research interest for the scrubbing of CO2 in post-combustion processes. The DOE has set a new target for post-combustion CO2 capture of less than a 35% increase in the cost of electricity, while capturing at least 90% of...

Troubleshooting Silicon Contamination on Hydrotreatment Catalysts - Sources, Impacts and Mitigation

Mar 23, 2010

Jaildes Britto

This paper discusses the impact of silicon on the deactivation of naphtha desulphurization, pygas hydrotreatment and platforming catalysts, and describes an improvement in the feedstock quality control, motivated by the occurrence of that contaminant in the straight run naphtha used by Braskem...

CFD Simulation of Vapor Dispersion from LNG Jetting and Flashing Releases

Mar 23, 2010

Filippo Gavelli

The analysis of LNG hazards, particularly in the context of onshore facility siting, has historically focused on the consequences of atmospheric pressure releases, such as would occur in the event of a storage tank breach. Recently, however, the issue of flammable vapor clouds formed by high-...

Fouling by Asphaltenes After and During Conversion

Mar 23, 2010

Irv Wiehe

During resid conversion processes, such as visbreaking or hydroconversion, more saturated pendant groups are cracked off asphaltenes, making them less soluble. Meanwhile, the more saturated volatile liquids formed during the conversion are often nonsolvents for asphaltenes. As a result, these...

Enhancing the Water Gas Shift Reaction Using Synthetic Sorbents for the Capture of CO2

Mar 23, 2010

Saquib Sultan

In order to capture the carbon content of coal, one option would be to gasify it with mixtures of, e.g. steam, CO2 and O2, to produce synthesis gas: the water-gas shift (WGS) reaction, CO + H2O <--> CO2 + H2, could then be used to increase the yield of hydrogen. In principle, if the WGS...

Safety Incidents in Ethylene Plants

Mar 23, 2010

Stephen De Haan

Many similar safety incidents occur in ethylene plants throughout the world. While these should be well known to plant operators, our paper lists these more common safety incidents along with their root causes. We then discuss several less common safety incidents that have occurred: • Heater over-...

Revamp Your Furnace – Enhance Technical & Financial Performance

Mar 23, 2010

Yong Wang

Furnace revamps provide opportunities to enhance new technologies, add feedstock flexibility, increase production capacity, improve efficiency and meet more stringent environmental regulations. With the current economic situation and anticipated environmental requirements, construction of...

Revamp Fired Heater to Maximize Thermal Efficiency

Mar 22, 2010

Ashutosh Garg

Fired heaters are in the refining and petroleum industry. In the current scenario, it is important to maximize fired heater efficiency to the maximum achievable. Revamping is a cost effective way to maximize fired heater efficiency: FIS has carried out several heater revamp projects in the past 5...
