Abstract :
This paper aims at quantifying the Health,
Safety and Environment (HSE) impact of some
flavonoid-derived demulsifiers using Chemical Scoring
Index (CSI). The CSI is based on the three-hazard
categories defined by United Nations’ Globally
Harmonized System for Classification and Labeling of
Chemicals (GHS) for defining greener chemicals.
Chemical components of each flavonoid-derived
product were quantified by scoring the level of hazard
posed by the component in relation to its percentage
composition in the product.-a carcinogen in a 10%
component of a product will be scored higher than in a
1% composition. Additionally, a ‘carcinogen’ is
weighted higher than an ‘irritant’. As such, products
with low CSI within same usage group are considered to
have lower intrinsic hazard and therefore used in
selecting best HSE green chemicals. Eight (8) products
were quantified; five (5) modified flavonoids and three
(3) commercial demulsifiers. ‘Modified Flavonoids-A’
was considered best HSE chemical with a CSI of ‘420’,
while ‘Commercial demulsifier-B’ was the least HSE
chemical with CSI of ‘1980’. It is recommended that
rather than focus on only the performance and cost of a
chemical product, it is essential to consider the Health,
Safety and Environment impact in the selection of
oilfield chemical products. This model will assist HSE
professionals in quick assessment of safer chemicals
alongside their performance.
