Understanding the Importance of Nitrogen Blanketing in Industrial Operations Nitrogen blanketing (also known as nitrogen padding) is a critical safety and process control technique used in industries like refining, chemicals, and petrochemicals. By maintaining a layer of nitrogen gas over liquid surfaces, this process creates an inert atmosphere that offers numerous benefits, including: 1. Preventing Combustion: Nitrogen reduces oxygen levels in the vapor space above flammable liquids, significantly lowering the risk of combustion or explosion. 2. Protecting Product Quality: As an inert gas, nitrogen prevents oxidation, contamination, and degradation of sensitive products, ensuring they maintain their integrity. 3. Minimizing Corrosion: With no oxygen present, the risk of corrosion on metal components such as tanks and pipelines is reduced, extending their operational life. 4. Reducing Vapor Loss: Nitrogen blanketing helps control pressure and prevents the evaporation of volatile organic compounds (VOCs), minimizing product loss and environmental emissions. 5. Maintaining Pressure Control: By regulating pressure within storage tanks, nitrogen blanketing helps prevent dangerous overpressure or vacuum conditions. ??Applications in Refinery Operations: -Storage Tanks: Protects volatile substances like gasoline, diesel, and crude oil by preventing the vapor space from reaching the flammable range. -Chemical Reactors: Maintains an inert environment to avoid unwanted reactions, ensuring safe processes with reactive chemicals. -Pipeline Systems: Prevents internal oxidation and contamination, especially during downtime or maintenance. -Loading/Unloading Operations: Ensures safety during the transfer of volatile liquids by keeping a protective nitrogen atmosphere. -Fire Suppression: Acts as an additional fire protection layer by displacing oxygen in hazardous areas. ?? Key Components of a Nitrogen Blanketing System: -Nitrogen Source: Onsite nitrogen generators or liquid nitrogen storage. -Pressure Control Valve (PCV): Regulates pressure in the vapor space of tanks. -Blanketing Valve: Automatically introduces nitrogen when pressure drops below set points. -Relief Valve and Vent System: Prevents over-pressurization by releasing excess pressure. -Inert Gas Monitor: Ensures the nitrogen concentration remains adequate to keep the atmosphere inert. -Adopting nitrogen blanketing is essential for ensuring safety, protecting valuable assets, and maintaining product quality in many industrial processes. #NitrogenBlanketing #FireSafety #IndustrialSafety #RefineryOperations #ProcessControl #CorrosionPrevention #ProductQuality #VaporLossReduction #EnvironmentalSafety #Engineering #SafetyInIndustry #ChemicalProcessing

?? Hydroprocessing Troubleshooting Series, Lesson No. 29: Product Sulfur ?Throughout this series, we’ve examined critical product specifications such as copper strip test, lubricity, viscosity, haze, and color. Each of these parameters plays a vital role in product quality. Now, let’s turn to one of the most critical specifications: Sulfur content. ?Elevated sulfur levels in hydrotreated products can be challenging, but a systematic approach can help pinpoint the root cause and guide corrective action. Here’s a concise troubleshooting guide: 1. Check for Contamination: Contamination with untreated feed material is one of the most common causes of elevated sulfur levels. Investigate potential sources systematically: ?Conduct a pressure profile survey across heat exchangers to identify potential leaks in heat exchangers, focusing on Feed/Effluent Exchangers: These are often the primary culprits, especially after upsets that cause thermal shocks. The product side often has higher pressure at a low-pressure section, reducing the likelihood of contamination there. 2. Startup Line Isolation: Ensure startup lines are fully isolated to prevent contamination. Don’t assume this step has zero likelihood—there’s always the possibility of human error or oversight (and, as we all know, Murphy’s Law applies here too, see Lesson 10!). I’ve seen cases where the valve was forgotten, leading to unnecessary contamination and headaches. 3. Check Hydrogen Partial Pressure and Feed: Check hydrogen partial pressure and verify there are no changes in the feed blend, SimDist FBPs, or crude type that could contribute to elevated sulfur levels. 4. Utilize Diagnostic Tools: If contamination and feed variations have been ruled out, use these tools to dig deeper: Temperature Response Test, Heat Exchanger Leak Detection: Use online methods or tracer techniques to pinpoint leaks and Product GC Analysis (see Lessons no. 15, 16, 18, and 19). 5. Look Beyond the Unit: Remember, changes upstream may impact the hydrotreater. Upstream units like CDU, Coker, FCC, HPU, or PSA may impact the product. Keep a close eye on their operations as well. Final Thought: ?Troubleshooting hydroprocessing units requires focusing on both equipment and operational conditions. Even small changes can have a cascading impact on the product (remember the butterfly effect, lesson no.4). #Hydroprocessing #Troubleshooting #refinerytroubleshooting #TopsoeAcademy #Topsoe

Desalters: The Biggest Inefficiency at Most Refineries This is what we often hear from our customers. The issues are real, as are the associated costs. Sometimes, crude oil and water take longer to settle than expected, leading to negative impacts. Water can hit the electrostatic grid and short it out, or it can carry over to the crude tower, causing damage to the tower trays (due to the expansion of water into steam) and resulting in corrosion. At other times, the rag layer increases to the point where oil is carried out with the brine. When this happens, the water needs to be sent to a slop tank, as there is too much oil for the wastewater treatment system. The PST Fluid ID is an acoustic device that can be attached to a pipe or vessel to determine the product on the other side of the wall. It uses "acoustic fingerprinting," as oil and water have very different fingerprints, even if their specific gravities are the same. The device can detect a 0.1% change in composition. By placing a PST Fluid ID on the upper level (where samples are usually taken), it can identify any water ingress into the crude. Alternatively, placing one at the water outlet near the bottom of the desalter can determine if oil is exiting with the brine. Most desalter units were built with six tri-cock valves for manual sampling. By installing a Fluid ID at each level, you can monitor the expansion and contraction of the rag layer. This can lead to reduced chemical additives and greater efficiency.

I'd like to share some information about one of the essential devices in the oil refining industry: (Distillation Towers) Distillation towers are equipment used to separate the different components of crude oil based on their boiling points. Distillation is one of the first steps in refining crude oil, where it is separated into components like gasoline, kerosene, and diesel. Components of a Distillation Tower: 1. Main Column: - A tall vertical structure fitted with internal trays or plates that aid in separating the components. 2. Distillation Trays: - These trays increase the contact area between vapor and liquid, enhancing the efficiency of the separation process. 3. Condensers: - Cool the vapor exiting the top of the tower to condense it back into a liquid. 4. Reboilers: - Heat the liquid at the bottom of the tower to produce vapor, which helps in the separation process. Importance of Distillation Towers in Oil Refining: - Component Separation: Enable the separation of crude oil into usable products like gasoline and diesel. - Quality Improvement: Help improve the quality of refined products by removing impurities. - Efficiency: Increase the efficiency of the refining process by recovering usable components. Challenges and Solutions: - Temperature Control: Requires precise temperature control to ensure efficient separation of components. - Corrosion and Fouling: Towers can suffer from corrosion and fouling, necessitating regular maintenance and the use of corrosion-resistant materials. #chemicalengineering
