Loss Prevention

Experience with naphtha in sour water emulsions generated in a fractionator overhead accumulator

McKnight, C., Rumball, B., Syncrude Canada Ltd.

A number of conversion processes, both hydrogen-addition-based and carbon-rejection-based, crack heavy oil into lighter hydrocarbon products.

Syngas from H2S and CO2: An alternative, pioneering synthesis route?

Manenti, G., Alfa Laval Olmi SpA; Molinari, L., KT-Kinetics Technology SpA; Manenti, F., Politecnico di Milano

Hydrogen sulfide and carbon dioxide represent major concerns for the hydrocarbon industry. Both species are contaminants and, since their use as feedstock is minor, are considered troubling byproducts.

Innovations

Andrew, Bob, Hydrocarbon Processing Staff

Unintended fugitive emissions from pressurized plant components have long been a key concern for operators as well as regulators.

How small deviations and lack of management access compromise reliability

Bloch, H. P., Hydrocarbon Processing Staff

In 2013, Refinery “X” was experiencing serious pump distress—the third or fourth in a 12-month period. We received calls about the latest thrust bearing failure event on this important 3,560-rpm process pump. Soon after, a surprisingly similar incident happened at Refinery “Y” in 2015. Both incidents are considered here.

Failure prevention—The ultimate asset management strategy

Snider, B., Small Hammer Inc.

The primary cause for losses and lost opportunities at refineries, chemical complexes, pipeline networks and gas processing facilities is equipment failures.

Engineering Case Histories: Case 90: Precautions when working near equipment

Sofronas, T., Consulting Engineer

Most machines and pressure vessels are designed with safety in mind, but they can release large amounts of energy if not constructed, maintained or operated correctly.

Codes and Standards: How much fireproofing do we need?

Murti, D. G., The Augustus Group

This article is the first under the Codes and Standards series. The purpose of this series is to make readers aware of code requirements, the interpretations and the limitations as they stand today, and what engineers can do as an alternative engineering. This series is based on the actual implementation of what is narrated and the satisfactory experiences drawn.

Improved corrosion prevention with acid-aided regeneration technology

Enhancing regeneration in amine treating systems has proven beneficial in many applications by improving operations and relieving design limitations via reduced steamrates and/or improved treating performance.

Meet EPA Tier 3 clean fuel regulations through improved blending processes

Truesdale, P., Carugo, M., Emerson Process Management

This article will examine the impact of Tier 3 regulations on gasoline blending at refineries and terminals, and illustrate options that can contribute to compliance while keeping costs under control.

Editorial Comment: Corrosion prevention is a necessary cost

Blume, Adrienne, Hydrocarbon Processing Staff

Corrosion is a major maintenance and reliability concern because it has the potential to impact not only plant operations and costs, but also the environment and worker health and safety.
