February 2013 - Seminar - Topside fouling in Oil Production

Topside Fouling in Offshore Oil Production

A mini seminar for the discussion of the fouling challenges met in offshore oil production.

Seminar

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
of man-hours.

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.

Program:

10:45 – 10:55 Welcome and Introduction

John O. Mortensen, Danish Technological Institute

10:55 – 11:40 Inorganic scale formation on engineering surface; mechanisms and means of management

Anne Neville, Leeds University

This presentation will address the issues associated with the management of calcium carbonate and barium sulphate scaling in the oil and gas sector.The formation mechanisms will be examined in addition to an assessment of the practical means of managing scale problems.

The current research in this topic in the University of Leeds will be discussed.

11:40 - 12:25 Fouling in Heat Transfer Equipment

Les Jackowski, Chevron Energy Technology Compan

  1. Industrial Perspective on Fouling in Heat Transfer Equipment
  2. Impact of Fouling (cost, safety, efficiency)
  3. Examples of Fouled Exchangers
  4. Physics of Fouling / Fouling Models
  5. Fouling Mechanisms and Mitigation
  6. Chevron Research Activities to Mitigate Fouling

12:25 – 13:10 Lunch

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.

15:10 – 15:20 Final Remarks

15:20 – 15:45 Reception
