🌍🔋Optimizing Hydrogen Production with PROGEF In the quest for efficient 🌱green #hydrogen production, the quality of water used in electrolysis is crucial. Different electrolyzers require varying levels of #WaterPurity, and impurities can significantly impact performance, operational costs, and the lifespan of the electrolyzer stack. #GFPipingSystems #PROGEF welded #polypropylene piping systems stand out with their excellent leach-out behavior, thereby mitigating the risk of ion content and facilitating low conductivity rates. These properties help ensure that the water remains within the optimal quality range, supporting the efficiency and longevity of your #electrolyzers. 💦 Explore how polypropylene piping systems can drive better performance and reliability in your hydrogen production projects. 👉 https://lnkd.in/gEcyTk5x Contact us 📲 https://lnkd.in/gPk4Wb59 #PPH #WaterTreatment #UltrapureWater #UPW

#Biobased feedstocks for #Fuel or #Chemicals production, represents an important part of the decarbonization puzzle. Upgrading these feedstocks often requires challenging process conditions of high temperature & pressure and requires corrosion-resistant materials. This #CSTR based system from Integrated Lab Solutions was specifically designed to handle high viscosity biobased feedstock, which are continuously added to a slurry-catalyzed high-temperature/high-pressure hydroprocessing reactor. The reactor is capable of reliable level control whilst simultaneously keeping the fine slurry catalyst fully contained in the CSTR. Gas & Liquid are continuously removed and the liquid sampling is fully automated taking samples into sample bottle for later offline analysis.

Another insightful discussion on the effect of heavy hydrocarbons in syngas manufacturing. Sharing from experience, changing composition of natural gas is a serious emergency at Ammonia plant and it takes a lot of effort to manage the change and normalize the plant.

Let's talk about #Syngas plants and #sulfurpoisoning (with a focus on the #primaryreformer or #SMR) with Anton Kariagin, one of Clariant's syngas subject matter experts. To avoid sulfur breakthrough in the first place: 🌟 Monitor your desulf. section - check sulfur in/out, track sulfur pick-up compared to the maximum amount your bed can handle 🌟 If you're using Clariant's service portal CLARITY®, consider using this tool to help you monitor your bed But, we all do everything we can and inevitably sulfur breakthrough downstream may occur. What happens if you have sulfur coming in to your plant? This is configuration dependent but the main reactors to worry about are: 🌟 Pre-reformer and/or the primary reformer 🌟 Low temperature shift (LTS) On the primary reformer #catalyst, sulfur lays down on the catalyst which blocks active sites. When this happens, the heat is not pulled away from the tube walls (as it normally is from the endothermic reaction of reforming) and you may visually see hot banding or hot spots on the tubes (these visually look like brighter spots on your tubes). On the LTS catalyst, sulfur is a permanent poison. So what can we do? For the primary reformer you can: 🌟 Monitor tube wall temperatures - operating too hot or above design severely impacts tube life. 🌟 Consider a steam-out to help regenerate the catalyst and remove the carbon formation. Excessive steaming can negatively impact catalyst activity so you want to balance steam and carbon removal but not do it too long or too frequently. 🌟 For severe poisoning, you can consider a steam/air regeneration. Has anyone had success regaining primary reformer catalyst activity after a sulfur poisoning event? What method did you use to regain activity? What reasons did you see sulfur poisoning in your plant? #neverstoplearning #ammonia #hydrogen #methanol #Clariant

Let's discuss what happens when you get heavies coming into your #Syngas plant with Taylor Archer! What are some things to look at if this happens to you? 1) Monitor the dP in your zinc oxide (ZnO) bed as well as sulfur in / out. a. Heavies can crack in the feed gas coil resulting in carbon laydown on your ZnO bed which could be seen by an increased dP b. With heavies sometimes come sulfur which means you're using up more of your ZnO bed which would mean a shorter lifetime and earlier breakthrough than originally planned. 2) Monitor your primary reformer or #SMR (steam methane reformer). a. With heavies could come cracking and carbon laydown which block active catalyst sites. This is of particular concern for plants without a pre-reformer and/or who run a S/G ratio on the lower end of the spectrum. b. You might visually see this as similar to sulfur poisoning - 30-40% down the tubes your catalyst can't complete the reformer reaction (active sites are blocked) and could see hot spots or hot bands. 3) Operationally, you can increase the S/G ratio to minimize the effects and catalyze the removal of some of the carbon. 4) Also consider an alkali promoted catalyst layer on the top 40% or so of your SMR as insurance to help defer or minimize the effects of carbon laydown. 5) If the effects are severe enough, you can consider a steam-air regeneration procedure to remove the carbon and help restore the SMR catalyst activity. Huge thank you to Taylor for sharing his knowledge (not just in this video but pretty much almost every day. :-)) #Clariant #catalyst #ammonia #methanol #hydrogen #neverstoplearning
