Design operations-and-maintenance-friendly pressure vessels—Part 2

Murti, D. G., The Augustus Group

In Part 1 of this article, the assistance provided by standardizations to gain improved vessel performance—vessel outer diameter (OD), component metallurgies, manways and saddles—was discussed.

Metrohm develops ASTM acid number method for petroleum products

A method of determining the acid number in crude oil and petroleum products using thermometric titration has been developed by Metrohm and released by the ASTM.


Andrew, Bob, Hydrocarbon Processing Staff

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

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.

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.

Major accident and failure of stationary equipment in the RFCCU

Seok, W., Lee, S., SK Energy

The four case studies cover component failures and multiple types of leakage: valve packing, expansion joint and corrosion.

Control fouling on preheat trains with a two-stage approach

Fouling in heat exchanger preheat trains is a well-known problem in the refining industry.

Emerson unveils new system to monitor corrosion

A chemist’s perspective on organic fouling in ethylene operations: update

Hancock, J. M., Nalco Champion; Robson, I., Vachon, J., SABIC Technology & Innovation

Ethylene manufacturing is a continuous race to be commercially competitive in a volatile global market.

Determine fouling margins in tubular heat exchanger design

Fouling, which is caused mainly by the deposition and accumulation of an undesired layer of solids on a heat transfer surface, is very common in tubular heat exchangers.
