APC maintenance scheduling—Part 1

Advanced process control (APC) projects are supervisory programs that are often thought of as a layer of control above the base regulatory control for a process. The benefits of APC include increased throughput, reduced variation, constraint avoidance, etc., and can be combined to represent a daily economic-equivalent benefit for the application—the same anticipated benefit that led to the justification of the APC installation. Several articles report that after 18 mos–24 mos, more than half of APC installations are performing at either pre-installation levels or have been removed.1,2,3 Although diverse reasons exist for the performance shortfall, a primary reason is that the process characteristics drift from those that generated the controller model.

Digital: Technologies are advancing industry beyond alarm management

Let’s face it, alarm management is a fully mature body of knowledge. Since the mid-1990s, industry has improved thousands of alarm systems, transforming them from overloaded nuisances to valuable operator tools for abnormal situation detection and response.

Innovations

Honeywell is developing a OneWireless™ IoT Module for the next generation of Cisco’s industrial access points, the Cisco Catalyst IW6300 Heavy Duty Series Access Point. The Honeywell and Cisco technologies will form the backbone of Honeywell’s OneWireless Network.

Business Trends: EPC 2030: Five vital characteristics that will define the EPC firm of tomorrow

The state of the global engineering, procurement and construction (EPC) industry can accurately be described as “challenging.” Operating in an environment of volatile, uncertain, complex and ambiguous conditions, EPC firms are facing unsustainable levels of stress.

RAM analysis for refinery process design optimization

RAM refers to reliability, availability and maintainability analysis. The RAM model uses discrete event simulation (DES) software and provides a quantitative assessment of the performance of an industrial plant. This article discusses the use of RAM analysis on petroleum refinery projects to select an optimum process configuration and associated storage requirements.

Optimization study in hydrocracker unit using simulation model

Hydrocrackers are key refinery units that convert heavy feed components into valuable lighter products. The profitability of these units is directly related to this conversion level. Conversion reactions take place in a nearly pure hydrogen environment, with the help of selective catalysts, under high pressure and high temperature. The products of the unit are separated in the fractionator section. Unconverted oil taken from the fractionator bottoms reveals the conversion performance of the unit.

Digital: Better maintenance through better data

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.

Process Safety: Process safety in a connected world

Traditionally, conversations around automation and safety have focused largely on logic solvers and instrumentation. However, new disruptive technologies and a rapid expansion in networking and computing resources have broadened the scope of automation’s reach. These transformative technologies and approaches promise to reduce incidents and increase production in ways industry could only imagine in the past; but while the “pieces” are available, organizational silos and entrenched cultures stand in the way.
