Research Interests

I am currently a visitor in Paste, Particle and Polymer Processing group (P4G) and a research engineer at HTRI. My research interest is in solving problems associated with the formation of unwanted deposits (fouling) in heat exchangers and associated networks.

Past projects

Fouling in crude refinery preheat trains (IHS, 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 was developed. The simulator takes plant monitoring data to evaluate 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 ageing of the fouling deposits. Ageing is, like deposition, often sensitive to temperature, so that heat transfer, deposition, and ageing 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.

Carbon Brainprint (with Cranfield University)
The 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, focused on quantifying the impact of research done in the area of scheduling cleaning on refinery preheat trains on reducing carbon emissions.

Fouling in sugar refineries (with Sebastien Sors, Polytech Nantes, France)
On a sugar beet refinery, raw sugar juice is preheated using a network of heat exchangers before entering a series of evaporators which concentrate it prior to crystallisation. These heat exchangers undergo severe fouling due to the crystallization of sulphates and carbonates present in raw sugar beet juice and wash water. The preheating is performed by recovering heat from crystallizer and evaporator vapours and condensates. This work describes mitigating fouling in the sugar refinery preheat train through scheduling of heat exchanger cleaning based on a heuristic algorithm described by Ishiyama et al. (2009). The objective is to minimise the use of a valuable heating utility stream by the judicious use of cleaning actions. A case study based on a British Sugar refinery, published by Smaïli et al. (1999), is  revisited. The results are compared with those obtained by Smaïli et al. employing an MINLP/NLP formulation. Both approaches demonstrate the economic benefit and technical feasibility of fouling mitigation by manipulating cleaning.

A techno-economic analysis of the performance of antifouling coatings in food industry heat exchangers (with Leonardo Gomes Da Cruz, University of São Paulo)
Coatings for reducing the rate of fouling on heat transfer surfaces are often promoted as a viable mitigation option in the food sector. The financial attractiveness of such coatings for retrofit applications is considered, where an uncoated exchanger is replaced by a coated one. The replacement unit may be larger owing to the extra thermal resistance introduced by the coating. The annualised operating costs are calculated, based on optimised, regular fouling and cleaning cycles as well as the annualised cost of the replacement unit. Fouling rates based on literature values are used. The attractiveness of the coating is very sensitive to the reduction in fouling rate if this can be achieved over the lifetime of the unit. The marginal benefit, which must include the additional cost of the coating, can then be estimated.
