Hexxcell mission is to bring digital innovation to industrial thermal systems. We combine Artificial Intelligence (AI) with physics-based models and deep domain knowledge to monitoring, design and maintenance of heat exchanger networks. Our hybrid digital twins are used by refineries and petrochemical plants worldwide to increase production, cut energy consumption and CO2 emissions, optimally manage operations and maintenance. Hexxcell spun-off from Imperial College London in 2013. Ever since, we have developed our technology in large scale multidisciplinary R&D projects in collaboration with oil majors and validated extensively on their plants. We are now an independent private company based in Central London and a proud team of chemical, mechanical and process systems engineers with deep knowledge of heat transfer, mathematical modelling, artificial intelligence and a knack for data science.

In this new series of posts, we will continue our journey through fouling with our Heat Exchanger Consultant Himanshu Joshi, to identify the dominant fouling mechanism. We will start by investigating fouling in single-phase liquids and gases. Click on the carousel below to learn more! 👇 #FoulingAnalysis #ProcessIndustry #FoulingMechanism #HeatExchangers
We are pleased to announce that Hexxcell will be attending the 2025 AIChE Spring Meeting and 21st Global Congress on Process Safety in Dallas, Texas. Hexxcell’s Head of Digital Innovation Niccolo Le Brun will present the results of applying a hybrid-AI digital twin to model both the heat exchanger and the separation units to determine an optimal cleaning schedule. Organised by AIChE - American Institute of Chemical Engineers, the world's leading organisation for chemical engineering professionals, the technical conference will provide comprehensive coverage of all major aspects of the chemical, process, and process safety industries. ➡️ To register for the event, please visit this page: https://lnkd.in/e-QcMyAs #AIChESpring #GCPS #ChemicalEngineering #ProcessSafety #AIChE2025
This is the last in a series of posts looking at techniques for measuring fouling deposition. Sometimes first level testing (TGA + elemental analysis and microscopy) leaves some uncertainty, or you need to identify specific substances. In these cases, we recommend using second-level testing to determine the whole composition of the deposit.

Step 3 of the procedure to measure the composition of a fouling deposit recommended by our Heat Exchanger Consultant Himanshu Joshi involves the use of Elemental Analysis. Find out more in the carousel below! #FoulingMitigation #HeatExchangers #ProcessIndustry #FoulingDepositMeasurement
In the previous post we explained how to correctly prepare a sample to analyse a fouling deposit. We now focus on the analytical methods available to identify the organic and inorganic components of the deposit. Thermogravimetric Analysis (TGA) is recommended because it’s fast, cost effective and provides a good amount of useful information. #FoulingMitigation #HeatExchangers #ProcessIndustry #FoulingDepositMeasurement
In our previous post series, our Heat Exchanger Consultant Himanshu Joshi explained what the main causes of fouling in oil & gas heat exchangers are. By looking at the different types of deposits that form on heat transfer surfaces and how fouling varies depending on the fluid phase, we can take better measures to prevent fouling and optimise the cleaning schedules. In this new series, we will explain how to measure the composition of a fouling deposit through accurate sample preparation and specific tests. The procedures explained below are relevant to deposits resulting from petroleum in heat exchangers. However, the concepts can be applied to other process heat exchangers by using the appropriate solvents and test methods.

Did you know that preheat trains in crude distillation units aim to recover up to 70% of the energy required for primary fractionation of the crude in the distillation column? Preheat train fouling can reduce heat exchanger performance and increase fuel costs and CO2 emissions, impacting refinery profitability. Hexxcell’s Hybrid-AI technology can help your company optimize preheat train operations, reduce fuel consumption and CO2 emissions and improve profits. 🔎 Explore our solutions: https://lnkd.in/dBmZrZM8 #CrudePreheatTrainFouling #FoulingMitigation #HexxcellStudio
Fouling in heat exchangers is one of the most challenging problems faced by the process industry today which leads to increased environmental impact of operations, large energy consumption, production losses and unplanned shutdowns. Hexxcell's industry validated solutions for fouling management and mitigation are powerful operational excellence tools that enable data driven decision making in operations, maintenance, production planning, profitability and environmental sustainability. 📹 Watch our corporate video and learn about our digital solutions here: https://lnkd.in/dEUXf4Qn #HeatTransfer #HeatExchangers #DigitalTransformation #HybridAITechnology #HexxcellStudio
Oil blending in refineries affects production yields and fouling behaviour in the pre-heat train and in the furnace of the atmospheric distillation unit. Despite some guidelines for oil incompatibility exist, predicting the impact of blending decisions on the fouling behaviour together with the operating conditions, heat exchanger configuration and current state of the equipment is still a major challenge. ➡️ Crude Slate Design™ is an add-on module to Hexxcell Studio™ specifically designed for oil refineries. Oil planners can utilize this tool to: 1. Predictively assess the impact of oil selection on fouling behaviour 2. Evaluate the impact of blending decisions on operations 3. Quantify the processing costs, both in economic and environmental terms. Moreover, the insights provided by Crude Slate Design™ can be used to further optimise plant performance and maintenance actions, such as the generation of optimal cleaning scheduling based on various KPIs. 👉 Learn more: https://lnkd.in/d3ch437e #ProductionPlanning #OperationalEfficiency #HeatExchangerMaintenance #HexxcellStudio #OilandGas #OilRefinery
We are pleased to announce that Hexxcell will be attending the conference “Heat Transfer & Fluid Separation in the Energy Transition” to be held at University College London on 28th March 2025. Our Head of Digital Innovation Niccolo Le Brun will present a study showing the results of applying a hybrid-AI digital twin to model both the heat exchangers and the separation unit to determine an optimal cleaning schedule. Organised by the Institution of Chemical Engineers (IChemE)’s Fluid Separations Special Interest Group and the Heat Transfer Society , this event brings together industry leaders, experts and academics to explore the critical role of heat transfer and fluid separation technologies in the energy transition. We look forward to seeing you there!
