Using OLI Flowsheet Optimizer - Thermodynamics
June 10, 2021

An OLI customer reported that the amount of a lithium sulfate solid observed in a pilot plant was severely underpredicted by OLI Flowsheet. OLI has determined that the binary interaction parameters had not yet been developed for the system of interest. The Optimizer Tool in OLI Flowsheet can quickly develop these parameters to match the observed plant data. Jim Berthold will show how he determined which parameters are missing and which need improvement. Jim will then go on to explain his rationale to use the optimizer tool to develop or improve the parameters. Finally, he will show how to model the plant using the updated parameters. This is the beginning baby steps in developing digital twins to existing processes.


OLI Cloud App Builder in the V11 Platform – Refining Industry Applications

May13, 2021

Operating conditions in a refinery are ever-changing, making the ability to capture windows of opportunity paramount to unit profitability.  Refiners have a wide variety of simulation tools at their disposal to decide if flow rates, temperatures, pressures, cut points, etc. can be changed in order to increase production and capture additional profits. However, these changes can have a detrimental effect on unit reliability, increasing corrosion and fouling of the system. In the past, process technology groups had to depend on experts to set up and run models and advice the refiner if the change in operating conditions will affect the unit negatively, often with an answer a few days later when part of the opportunity (or all of it) is lost.  During this spotlight, Ezequiel will demonstrate OLI’s Application Builder and how this cloud-enabled tool empowers expert teams to deploy simple, easy-to-use applications,  providing operations teams with the tools to make decisions in a matter of minutes, rather than days, and capture the entirety of the opportunity

There are multiple methods for treating brines produced from geothermal and oil and gas reservoirs.  Conventional operations like deoiling, H2S removal, solids removal, VOC removal, silica removal, and hardness removal are common methods to make the water suitable for reuse as steam, water injection, or disposal.  What is new, and interesting, is the research and development around extracting greater value from these enormous quantities of water.   For example, certain produced water contains an appreciable concentration of lithium that is profitable to remove.  Others have suitable salt compositions that make them easier to process into reusable waters using new separation technologies. We will look at some of these examples in this spotlight presentation.

In 1961 President Kennedy said “No water resources program [speaking of a DOW-Freeport desalination plant] is of greater long-range importance than our efforts to convert water from the world’s greatest and cheapest natural resources – our oceans – into water fit for homes and industry. Such a break-through would end bitter struggles between neighbors, states, and nations.” This statement is still true more than 50 years later with more than 40 % of the world’s population suffering from water shortages. This percentage expected to increase to more than 60% in the next 10 years.
