The increasing use of animal and vegetable feedstocks for liquid fuel production has become common practice, but questions still remain regarding optimum coating choice and information required to correctly evaluate the available options. The paper will explore the relationship between two different standard test methodologies (isothermal and temperature differential atlas cell) across key specification variables such as temperature, free fatty acid and water content on formulations with differing barrier pigments to help clarify current concerns regarding subjective assessment and test suitability. The performance test results will then be used to evaluate lining selection, focusing on optimizing installation and considering more practical aspects such as lining specification, application methods, object configuration and completion time.
