Process Control
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.
Optimal gas analysis decisions improve ethylene plant operation
One of the most common and important building blocks in the petrochemical industry is ethylene, constituting a huge and fast-growing worldwide industry. Ethylene is an intermediate chemical used to manufacture many commercial products—approximately 200 MMt will be produced in 2020.
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.
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.
Editorial Comment: Honoring the industry’s best … take 2!
Due to Tropical Storm Imelda, Hydrocarbon Processing issued its first force majeure in postponing the third annual HP Awards.
Sustainability and the water management company’s role
Water is key to the hydrocarbon processing and chemical processing industries. Yet, it is not an infinite resource, which creates operational, financial and regulatory risks. The true cost of water can include insurance and litigation costs and disposal costs, plus the capital expenditures (CAPEX) and operating expenses (OPEX) of water infrastructure.
Using ball valves in high-temperature applications
Ball valves are often an economical solution for controlling flows in refinery high-temperature applications, but their application can be complex, particularly in high-temperature uses.
When digital transformation hits all four sustainability buckets
Sustainability is emerging as a critical business topic, as many companies focus resources toward lowering emissions, waste and energy use in their production processes. This important concept can apply broadly to company operations, especially when considering the expansive view of the triple bottom line that measures the impact of company operations on profits, people and the planet.
