emissions, as shown in Table 2 , resulted in a net saving of circa €2.7 million a year (the calculation includes the cost of Baker Hughes Lifespan service and antifoulant treatment). LIFESPAN™, ASIT™ Asphaltene Stability Index Test, LSCI™ Lifespan Concern Index, and LIFESPAN™ blending model are marks of Baker Hughes. Giuseppe Della Sala is a Senior Technical Advisor for the Downstream Chemicals division of Baker Hughes, specialising in fouling for more than 15 years. He is responsible for identifying on a case-by-case sce- nario, the best strategy required to eliminate or mitigate fouling in the downstream industry, conducting data analysis and oil samples char- acterisation, as well as supporting the development of future solution/ technology. He holds an MS in chemical engineering from Politecnico di Milano University. Marco Respini is Senior Principal Chemist for the Downstream Chemicals division of Baker Hughes with more than 25 years of expe- rience in crude oil chemistry, process modelling, and asphaltenes. He is the author of 20 journal and conference papers and an inventor of 12 patents in the area of fouling control and renewables. He was pre- viously a Research Fellow at Milan University in the field of organo - metallic catalysis and is a member of the American Chemical Society. Ben Morgan is the Global Refining Leader for the Downstream Chemicals division of Baker Hughes, specialising in refinery process chemical applications to enhance performance and equipment reliabil- ity. He has more than 17 years of experience in the oil and gas industry and is currently involved in crude flexibility, technical support, and trou - bleshooting of refinery desalting, corrosion, and antifoulant issues. He holds a PhD in organic chemistry and biocatalysis from University of Liverpool. He is currently a member of the Royal Society of Chemistry and Chartered Chemist. Email: ben.morgan@bakerhughes.com

day with WTI processing and without the Baker Hughes antifoulant was estimated (1.82°C/month) – a figure that was extremely reasonable from the RAM experience. The decay with the antifoulant program, with dosing rates optimised by the LSCI index, resulted in an NFIT decay of 0.013°C/day (0.40°C/month) – a 78% reduction of the foul- ing impact compared to the base case. Economics Baker Hughes and RAM calculated the following impacts of fouling with and without treatments using the previously determined NFIT on fuel gas consumption and CO₂ emis - sions on a yearly basis, with a unit feed rate of 800 tons/h (see Figure 6 ).
