CHAPTER 3 SYSTEM DESCRIPTION
3.1 Introduction
3.1.1 General
The main function of the MSC-L is to assist in loading the liquid
products from a storage area to another containment vessel. That is,
the MSC-L helps the smooth movement and accurate measurement of
the liquid product being transferred. The MSC-L is also capable of
creating a new composite product during the transfer operation by
combining one or more different products together to form a new
product. The MSC-L creates the final, required product based on a
user-supplied specification, known as a Recipe.
For more information about Recipes, refer to the section CHAPTER 5 -
Operation.
The types of composite products that the MSC-L can create is limited by
various physical constraints such as product piping, isolation valves, the
availability of pumps, and blend valves.
The MSC-L can create composite products by combining products
through one of the following methods.
Blending - The process of combining two or more products contin-
uously.
Additive injection - The process of injecting small and discrete
amounts of a product (an additive) into another product.
3.1.1.1 Transactions and Batches
The MSC-L uses the following terms to control and record the product
transfer process.
Transaction - A single user session during which one or more
batches may be initiated. A transaction also defines the basic unit of
financial reconciliation.
Batch - Loading of a preset amount of final product into a
compartment on the vehicle.
3.1.2 Batch principle
Batch is defined as the loading of a preset amount of the final product
into a compartment on the vehicle. This final product may be a single
product or a blended product made on-the-fly by the MSC-L. If more
than one compartment is available, then more than one batch per
transaction can be initiated. There are no dependencies between
batches. That is, each compartment has its own independent operation.
If there are more than one load arm associated with the MSC-L then
multiple batches may be running simultaneously in the MSC-L.
