Topside Fouling in Offshore Oil Production
A mini seminar for the discussion of the fouling challenges met in offshore oil production.
With a constant focus on enhancing the oil recovery from currently producing oil fields, the challenges posed by deposits formed in topside production equipment is ever increasing.
The deposits clog up production equipment, hamper safety, decreases energy efficiency and require a substantial number
This mini seminar focuses on the challenges of such deposits formed on surfaces in crude oil contact – and on a new solution.
The solution is a thin, flexible and resilient coating that efficiently repels deposits and is cable of several-fold extending the mean time between services for plate heat exchangers used in crude oil tempering.
Other possible applications for the coating will be discussed at the seminar.

13:10 – 13:40 Crude oil fouling research: a combined experimental and modelling approach
Francesco Coletti, Imperial College
Fouling is a common problem in heat transfer equipment that hinders energy efficiency, increases pressure drops and disrupts routine operations. To be able to mitigate - and eventually prevent – this formation of unwanted material on thermal surfaces it is necessary to improve the understanding of the underlying deposition mechanisms which are still poorly understood.
The aim of this presentation is to introduce a framework that integrates quality experimental measurements and detailed mathematical modelling of all phenomena involved with crude oil fouling, at various scales. In particular, a novel experimental apparatus, the High Pressure Oil Rig, HIPOR, designed and built at Imperial College London to evaluate fouling propensity of crude oils at industrial conditions will be described together with the detailed mathematical model used for the interpretation of experimental results.
13:40 – 14:10 Antifouling Coating for Topside Equipment
Claus Bischoff, Danish Technological Institute
Crude oil contains a variety of substances which tend to deposit as fouling layers on contact. The fouling layers will eventually reach a magnitude that impacts operation and require service – which is both time consuming and expensive, especially on offshore installations.
Oil and Gas, Danish Technological Institute, has developed an advanced glass ceramic like hybrid coating system that efficiently prevents the fouling of both organic and inorganic origin in crude oil processing. In the presentation, the technology behind the coating is presented and possible application areas within offshore oil and gas production is discussed.
14:10 – 14:40 Coffee break
14:40 – 15:10 Reduce fouling with plate coating
Mats Nilsson, Alfa Laval AB – Plate Heat Exchangers
In the presentation the consequences of plate heat exchanger fouling is outlined and parameters influencing fouling is discussed. In order to circumvent or reduce fouling build-up, conventional coatings and a new coating is presented. The new coating has demonstrated a quantum leap forward in reducing fouling build-up on plate heat exchanger plates. The implications of the new coatings in plate heat exchanger maintenance is discussed.
