Welded vessels play a key role in most processes. However, few plants now have in-depth expertise in materials selection, fabrication and design of such vessels. As a result, plant staff often make errors that can be costly as well as compromise the suitability and life of the vessel. This three-part special report provides practical pointers that can help you avoid common mistakes and get the most appropriate, durable and cost-effective vessel.
Part 1 looks at a dozen important factors to consider in materials selection, including metal selection and appropriate use of corrosion allowances and coatings. It includes pointers gleaned from first-hand experiences that can help you avoid costly mistakes and delays.
Part 2 provides tips on how to avoid delays and achieve savings in the fabrication process. It also covers techniques that can improve vessel reliability and thus forestall costly repairs down the road.
Part 3 gets into design issues. It condenses the 5,000+ pages of the ASME Boiler and Pressure Vessel Code into a simple guide when specifying vessels, heat exchangers and tanks. It focuses on 10 key factors.

The pressure of international competition is being felt in the field of plant engineering with a demand for shorter development times and reduced project costs. A consistent and efficient approach to plant design can help to dramatically save both time and money. Download this white paper to learn more.
One of the difficulties of managing projects that involve several (perhaps many) organizations is that the group has no pre-established procedures for handling actions that cross organizational boundaries. This white paper by Project Success Incorporated discusses the development of a procedures manual.
This paper covers key aspects for modeling and design of batch reactors, including: heat-up and cool-down performance, sensitivity analysis for reactor parameters, boil-up rate predictions, thermal stability under exothermic conditions, control system design and loop tuning parameters, condenser rating, and process emissions predictions.
Shell-and-tube heat exchangers are widely used throughout the chemical industry. This paper provides a review of the key issues involved in their thermal design. It covers both process and mechanical issues, and discusses appropriate methods for determining various parameters.
This paper reviews the basic techniques for dynamic modeling of these two key operations. It covers considerations related to heat transfer, reaction chemistry, mass balances and the control system. It also discusses equipment configurations, performance characteristics and operational constraints.
