• CONDENSING EXTRACTION TURBINE CALCULATION: Condensing Extraction Turbine Calculation using Flex Live Software.

• CONTINUOUS PERFORMANCE MONITORING:This article will offer some reasons to continuously monitor compressor and turbine performance and present some case studies in support of continuous performance monitoring .

• ENHANCING ROTOR STABIITY:Whether instability of a rotor system is discovered by operation or by analysis, the best tool for correcting the situation is a rotor stability analysis program. Possible corrective measures can then be analyzed and the best possible solution can be selected. Some methods of improving stability are discussed in this article.

• EVALUATING MULTI-SECTION COMPRESSORS: Procedures, Equations, and Examples

• FLEXWARE SLEEVE SEAL LIFE: A case study based on the use of Flexware Gold Babbit on Seal Ring Bores.

• GAS PROPERTIES: A Listing of Various Gases and their Properties

• GAS TURBINE PERFORMANCE ANALYSIS: A regular check on the overall efficiency can tell a lot about the condition of the turbine and help decide if further investigation is necessary. All that is needed is the driven power and the fuel consumption.

• PARALLEL and DOUBLE FLOW COMPRESSORS: Recommended inlet piping for a double flow compressor.

• PRACTICAL STEAM TURBINE PERFORMANCE CALCULATIONS: A steam turbine’s power and/or efficiency can be quickly and accurately calculated using Flex Live’s Steam Flex routines for steam properties calculations.

• REMOTE MONITORING: A big advantage to doing equipment monitoring remotely is that it brings all the data together quickly and easily. At the touch of a finger! Saving us all time and money.

• RERATE CASE STUDY: As gas wells age, the pressure at the well head and the amount of gas flow decreases. So, in order to continue to provide gas to the end user, and meet the required gas distribution header pressure, the gas compressor must be rerated to provide more head (pressure rise) and flow rate.
