A method of linking source units of food with product items that include at least a portion of one or more of the source units of food, where a conversion process produces a plurality of product items from a plurality of source units (e.g., at a meat processing plant). A conversion algorithm is created to estimate within a desired confidence level a range of the amount of time required by the conversion process to produce a product item from one or more of the source units of food. A range of an amount of conversion time required to produce a selected product item is estimated by applying the conversion algorithm. The estimated range amount of conversion time for the selected product item is subtracted from the time of exit from the conversion process for the selected product item to generate an estimated time range of entry. Each source unit having a time of entry into the conversion process within the estimated time range of entry is identified.

A process for liquefying natural gas in conjunction with processing natural gas to recover natural gas liquids (NGL) is disclosed. In the process, the natural gas stream to be liquefied is taken from one of the streams in the NGL recovery plant and cooled under pressure to condense it. A distillation stream is withdrawn from the NGL recovery plant to provide some of the cooling required to condense the natural gas stream. The condensed natural gas stream is expanded to an intermediate pressure and supplied to a mid-column feed point on a distillation column. The bottom product from this distillation column preferentially contains the majority of any hydrocarbons heavier than methane that would otherwise reduce the purity of the liquefied natural gas, and is routed to the NGL recovery plant so that these heavier hydrocarbons can be recovered in the NGL product. The overhead vapor from the distillation column is cooled and condensed, and a portion of the condensed stream is supplied to a top feed point on the distillation column to serve as reflux. A second portion of the condensed stream is expanded to low pressure to form the liquefied natural gas stream.

A hardware and software implemented, standardize testing, scoring and reporting system has a network interface, being either LAN or the Internet. A test is selected from a library, assigned to a group of examinees, and a record is made of the assignment. The test is available on-line, or downloaded, or both. Downloaded tests are saved as PDF files and printed into booklets. Examinees record answers on bubble sheets, which are scanned at the customer site or shipped to a processing plant. Individual scanned answer sheets provided data for individual scanned records. Scanning software performs an initial auto-correct and then performs an initial check for errors in scanned records. Tests are batched for later inspection. Scanned records with errors are classified as invalid and the test papers are separated. Prompts are generated for a human test paper inspection and scanned record editing. Accepted batches of scanned records are sent to a scanned records server where a second scanned records error check is performed. Prompts are sent to the appropriate scanning station for further human editing of invalid scanned records. Once all records are valid they are scored and the test results stored in a database, which is accessed by a reporting subsystem associated with an on-line server.
