Computers data management programs

Today there are alternatives to the after-the-fact method of inhibitor monitoring and control, with the advent of automatic, semicontinuous, and continuous control methods that employ tagging and tracing and similar techniques. These newer methods can often be linked to computer data management programs. 

The host computer provides all of the data management, storage, report generation, and analysis capabilities of the predictive maintenance program. Therefore, care should... 

Ph.D., performed the computer programming and statistical analysis. Candace Young and Frieda Fisher helped with data management. William Bax, Joseph Wade, Charles Bennett, Gertie King, Dennis Miles, Jimmie Pickett, Frank Porter, Deborah Richardson, and Alice Roberts collected urine samples. 

A principal components multivariate statistical approach (SIMCA) was evaluated and applied to interpretation of isomer specific analysis of polychlorinated biphenyls (PCBs) using both a microcomputer and a main frame computer. Capillary column gas chromatography was employed for separation and detection of 69 individual PCB isomers. Computer programs were written in AMSII MUMPS to provide a laboratory data base for data manipulation. This data base greatly assisted the analysts in calculating isomer concentrations and data management. Applications of SIMCA for quality control, classification, and estimation of the composition of multi-Aroclor mixtures are described for characterization and study of complex environmental residues. 

Data System. An IBM-PC desktop computer is interfaced to the instrument control module to provide automated data collection and analysis. The data collection and analysis programs are menu driven. A data management facility is an integral part of the data system. A modeling utility is provided to aid the operator in chosing the operating conditions (rotational speed, spin fluid volume, fluid density, etc.) for a sample. Programming is done in compiled BASIC and the 8087 math coprocessor is used to improve computational speed. 

A data management system is an integral part of the program. This allows the operator to store experimental data on the computer s disks and to reanalyze stored data, or to simply review results without reanalysis. Using the cursor controls, the operator can select stored runs from the menu and print the results for those runs in tabular form. Selected runs can be deleted in a similar fashion. 

Successful rotating equipment Predictive Maintenance Programs require several elements. Typical elements include an effective lubrication program with oil analysis to detect residual metal particles, thermography, machine monitoring instrumentation, repair specifications, repair history records, advanced training of mechanics, and the use of data management computers.

In Computer Aided Operation we can mention the real time monitoring of material and energy balance, managed nowadays by means of data reconciliation programs. The plant operation can be adapted and optimised in real time by means of computerised tools based on dynamic flowsheeting. Other advanced applications are simulators for safety studies and operator training.
