Research description
Fouling in crude refinery preheat trains (IHS ESDU, London)
Crude oil refinery preheat trains are network of heat exchangers that are designed to reduce energy consumption but their operation can be hampered by fouling. Fouling behaviour vary between refineries. Effective management of preheat operation requires inspection of historical plant performance data to determine fouling behaviours, and the exploitation of that knowledge in turn to predict future performance.
Fouling results in major economic and environmental penalties. A state-of-the art preheat train fouling analysis and mitigation simulator, SmartPMTM (smart predictive maintenance), is developed. The simulator takes plant monitoring data extracted from the distributed control system to report past performance and predict future refinery throughput, energy use, emissions and optimum heat exchanger maintenance/cleaning schedules. The smart technology then allows “what if” scenario planning, for example to assess economic benefits of better heat exchanger design; the use of anti-foulant chemicals, or to assess cost and operational penalties through refining new crude blends.
Deposit ageing (with Ian Wilson and Bill Paterson)
The effect of fouling in heat-transfer devices is complicated by aging of the fouling deposits. Aging is, like deposition, often sensitive to temperature, so that heat transfer, deposition, and aging are coupled phenomena. We investigate methods to quantify thermal ageing of deposits. The model is extended to scheduling cleaning algorithms; aim is to generate guidelines in ‘when’ to use ‘which’ cleaning methods, where different degree of ageing results in different degree of cleaning.
Past projects
Carbon Brainprint (with Cranfield University)
This is a subproject under Cranfield University, where the novel aspect of Carbon Brainprint concept is introduced as the prospect of assessing the global impact of research and teaching in the Higher Education sector in mitigating global warming. The subproject at Cambridge, focuses on quantifying the impact of scheduling cleaning on refinery preheat trains on reducing Carbon emissions.
Fouling in sugar refineries (with Sebastien Sors, Polytech Nantes, France)
IHS ESDU SmartPM software (originally focused on assessing crude refinery preheat train performance) was successfully used in assessing thermal performance of sugar refinery preheat trains.
