Plant Balance

Gas Plant Balance is where monthly data for the sale of gas and by-products are entered including Receipts, Dispositions, and Consumption. The same screen is used for both Gas Flow and Non-Gas Flow plants. If the plant is using Ideal Product Shrinkage as the allocation method for at least one product, the IPS Order Table button will be visible to allow for maintenance of the Orders.

Summary Balance

The Balance area shows Receipts, Shrinkage, Consumption, Processed Gas and Metering Difference totals. Balance will run a preliminary calculation of by-product equivalent shrinkage etc. to calculate the Summary Balance.

The Summary Balance will look slightly different for plants that are allowing mix fractionation. There will be a couple of additional fields related to mix fractionation used in the balancing equation.

Balance Checks

When the plant is not balanced, Not Balanced is displayed above the Production Date with a Balance Check link next to it.

When the link is selected, all plant balance validations are executed again, and a window is displayed with the Balance Check Details.

A green checkmark is shown beside validations that are successful.
A red X is shown beside validations that failed.
A simple box with a dash (-) is shown beside validations that were not run due to a previous validation failing.

These visual indicators and associated descriptions should provide additional help to identify why the plant is not balanced.

Plant Production Validation - Displays all validations performed when balancing a plant.

Product Balance

The Product Balance grid displays a summary for each product. To view/update the Receipt and Disposition details for a specific product, highlight the product.

1. Click the Edit button to open the Product Balance grid to edit and update Gains/Losses or Closing Inventory.

The Gains/Losses and Closing Inventory fields allow data entry.
Action buttons include: Save, Revert and Cancel.

2. Click the Show Selected Only button to display the Product Balance section for the selected Product. There may be a large number of products being displayed, and therefore this button allows you to isolate the product that is being balanced.

When the Show Selected Only button is selected, the Product Balance grid only displays the selected product. The button label changes to Show All and two new buttons are displayed on either side called Previous Product and Next Product.

Click the Previous Product and Next Product buttons to balance the products one at a time.
Click Show All to display all the products again.

Receipts

When the product is highlighted, the entities in the schematic that deliver to this plant will appear in the grid with the volume that was sent. By-product receipts are assumed to be outside receipts brought in for fractionation or as a transfer for sale. Receipt rows from prior months appear in the grid for each product.
