Maintenance & Reliability

Editorial Comment: Adopting digital technologies to enhance operations

Nichols, Lee, Hydrocarbon Processing Staff

What is the future of refining and petrochemical operations? One trend that has been the focus of many articles, whitepapers and conference presentations is the digital transformation of the hydrocarbon processing industry (HPI).

Reliability: Consider successful pump redesigns: Start with a clean sheet of paper

Bloch, Heinz P., Hydrocarbon Processing Staff

You may recognize the “pre-owned” pump in FIG. 1 as an axially split, between-bearing, multistage model. Chances are that half of its impellers face right-to-left and half of them face left-to-right. In that case, there must be an internal seal or bushing that limits leakage flow from the pump’s higher- to lower-pressure sections. There must also be porting or piping that takes flow from the discharge of the lower-pressure section to the suction of the higher section.

Viewpoint: How digital transformation impacts daily manufacturing operations

Price, E., Honeywell Connected Enterprise

With the ever-increasing speed of technology innovation around the Industrial Internet of Things (IIoT) and cloud offerings, industrial manufacturers are evaluating how these new solutions can impact their daily operations. Specifically, they are looking at how these innovations enable real-time, actionable insights across processes, assets and the workforce. These insights allow for quicker and more informed decisions, thereby driving efficiency and profitability.

Inspection: A practical approach to internal inspection of pressure equipment

Anwer, A., Contributing Editor

Internal inspections of pressure equipment involve a full inspection of the equipment. Inspection engineers and inspectors depend heavily on internal inspections to retrieve useful data, which includes information on active degradation mechanisms, corrosion rates, remaining equipment life, failure occurrences and failure expectations, among other critical details.

Digital: How digital tools improve access to device information

Thompson, A., Emerson Automation Solutions

Welcome to the future! The plant runs fully automated; robots glide silently back and forth, ensuring an optimized process; and your maintenance technician—with a few keystrokes—can tell you exactly how each piece of equipment is running. The promise of the Industrial Internet of Things (IIoT) has been delivered.

Case study: Heat exchanger tube rupture and its impact on metal embrittlement

Dingankar, S., Mahulkar, S., Reliance Industries Ltd.; Schutt, M., Mahalingam, S., TechnipFMC; Banerjee, S., Technip India Ltd.

Process engineers strive to recover as much energy as is practically possible from the available process and utility streams within the constraint of the plant. To achieve this goal, traditional—and sometimes non-traditional—methods are utilized. In a steam cracker, light olefins are considered the highest-value products, and utilizing “cold energy,”

Reliability: Things rarely heard at reliability conferences

Bloch, Heinz P., Hydrocarbon Processing Staff

We can only guess how many reliability conferences we have attended since accepting job offers in the refining or chemical processing industries. In my case, starting in 1965, it is somewhere between 60 and 80. If, in each of these conferences I listened to six presentations, the number of sessions attended is perhaps 400.

Digital: Better maintenance through better data

Eichelberger, N., Accruent

When I talk to professionals in the refining and petrochemical businesses, they are always interested in how new technologies can improve operational efficiency, make plants safer and increase profitability.

Executive Viewpoint: Succeeding against cyber attacks

No doubt exists that the added connectivity that modern control and automation systems deliver offers a myriad of benefits. By embedding computing within the process and utilizing edge and cloud technologies, it can provide greater visibility. It creates a digital thread for the plant and allows both equipment and the processes to be analyzed, as well as giving prescriptive advice.

Equipment: Rotating equipment repair: The technology-driven shift from preventive to predictive

Pandita, R., Persistence Market Research

Rotating equipment repair vendors are looking at a future that can be described as both exciting and challenging. As predictive maintenance (PdM) makes deeper inroads, vendors have been forced to rethink their legacy repair offerings.
