Tracking the composition and quality of feedstock through tanks and material movements is a requirement for engineering and accounting applications.


Operators and engineers at chemical plants and refineries often need to estimate the composition and quality in each feedstock tank based on scheduled tank movements.

Unfortunately, the composition data provided by tank farm personnel suffers from inaccuracies, and actual movements may differ from scheduled movements.

Inlibra Composition Tracking (CT) addresses the following problems:

logo bug  Composition information for feedstocks such as crude oil or naphtha is often provided by one person in the supply chain with varying degrees of accuracy. Inlibra CT provides a way to check and improve those figures through calculations.

logo bug  Composition data is often calculated and provided to the refinery/chemical plant without regard for information obtained by balancing the plant. Inlibra CT’s input figures are based on knowledge gained by performing the plant balance.

logo bug  Inlibra CT understands that pipelines contain significant volume. Feedstock composition values as supplied without Inlibra CT are normally calculated without accounting for that volume.

logo bug  Traditional composition tracking calculations assume that tank blends are ideal mixes. Inlibra CT allows you to specify four different tank blend calculation methods, applied using time slices for greater accuracy.

logo bug  Inlibra CT can accept data from external crude assay systems to obtain quality data.
