Special Focus—Process Controls, Instrumentation and Automation

The use of AI in process plant control: A proof of concept
KBR: Ashesh, A.

The goal of this article is to highlight how: Supervised machine-learning and the Internet of Things can be used to develop a soft sensor that can enable the plant operator to continuously monitor product analysis, as well as gain insights into the root cause of off-spec product—in this work, the off-spec product is distillate. Also, this article will show how reinforcement learning can be used to train an AI agent to operate the plant. 

Reduce costs by following grab sampling best practices
Swagelok: Dixon, M.

Accurate grab sampling practices are necessary to validate the quality of chemical products with precise compositions. Operators must follow proper procedures to avoid compromising the sample. Otherwise, the result may be an inaccurate analysis of their product, leading to quality lapses and potentially costing a facility thousands of dollars in revenue.

How to select the right explosive-certified equipment for hazardous areas
Cygnus: George, D.  |  Jelly, C.  |  Wei, C. J.

When operating in a potentially explosive atmosphere, several crucial aspects must be considered. These include understanding the potential hazards and choosing the correct tools for the identified hazardous areas. The rules and regulations surrounding the use of equipment in hazardous areas are deciphered and explained within this work. 

Improving ammonia production sustainability
Emerson: Machuca, M.

While approximately 70% of ammonia production is used to make fertilizers, it is also identified as the largest carbon dioxide (CO2)-emitting chemical industry process. This article examines several novel technologies to improve the sustainability of the ammonia production process.

Environment and Safety

Safe design and operation of burn pit flare systems
Saudi Aramco: Al-Tijani, A. H.  |  Al-Mubayedh, M.  |  Al-Sanad, A.
Zeeco: Seefeldt, G.

This article will mainly focus on horizontal flare systems and grade-level burn pits. Design considerations, operational challenges and several lessons learned will be discussed. 

Design optimization of an HVAC system in a petrochemical plant’s controls building
CTCI Corp.: Zengjun, Y.

Since petrochemical plant control buildings are usually designed to be blast-resistant without external windows, convection ventilation cannot be carried out, leading to poor air circulation. As a result, there are higher requirements for indoor air quality, and it is necessary to optimize the heating, ventilation and air conditioning (HVAC) system design scheme to improve air quality.

Maintenance, Reliability and Inspection

SMR feed effluent hairpin exchanger: Once upon a time—An unusual thermal mix-point failure—Part 2
Suncor Energy Inc.: Gilbert, F.  |  Jacob, O.

This article presents a review of a failure that happened in a hairpin heat exchanger type on the shell side in a H2 (H2) reformer unit.

Use advanced thermal insulative coatings to improve safety, maintain access and protect against corrosion
Sherwin-Williams Protective & Marine: Wilds, N.  |  Dammen-Brower, E.  |  Daum, J.

Throughout refineries, petrochemical plants and offshore oil and gas platforms, personnel are often required to work near equipment that operates at high temperatures. Protecting those workers from skin-contact burns has typically involved two approaches: implementing physical barriers and covering the hot assets with insulation and cladding. This article details how thermal insulative coatings can be used to improve safety and guard against corrosion.

Hydrogen

Measuring hydrogen, tomorrow’s innovative fuel
Endress+Hauser: Castillo, C. M.

Because it can be stored, transported and burned without GHG emissions, hydrogen (H2) is emerging as a potential frontrunner as a clean fuel source. However, transporting H2 must be efficient and cost-effective, a task that requires careful consideration and innovative solutions. This article will examine requirements for effective H2 transportation and accurate measurement in its challenging environments.
