Abstract
A method for determining the oil and grease concentration of aqueous solutions on offshore facilities without having to ship the aqueous solutions to shore-based laboratories for analysis. The method generally involves a liquid-liquid extraction procedure, where a concentration of oil and grease extracted from a known volume of aqueous solution is determined using a pair of weighing devices, which are connected to a common computer which is capable of processing synchronized data points received from the two weighing devices. The first weighing device is a control scale upon which a reference mass having a known weight is placed. The second weighing device is a sample scale upon which the extracted oil and grease will be placed. Any wave motion, vibration, and/or other environmental and/or physical condition on the offshore facility affecting the first weighing device will also affect the second weighing device in like fashion, and therefore will be compensated for when determining the true weight of the extracted oil and grease.
