Enalysis Tip 1.15 - Enalysis Default Flagging Limits for Reciprocating Compressors

July 17, 2020
The Enalysis software provides YELLOW (Warning) and RED (Severe) flags to identify compressor limits and allow for action to be taken to prevent possible damage to the compressor package. Reciprocating compressor packages are restricted to operating under conditions that ensure the mechanical ratings of the compressor are not exceeded. Exceeding one or more limits of the compressor can result in catastrophic failures requiring expensive repairs and resulting in costly downtime. Yellow warning flags indicate that a limit is being approached and red severe flags indicate that a limit has been reached.

Enalysis Tip 1.14 - Compressor Performance Modelling with Enalysis Simulate

June 25, 2020
Enalysis includes a full-featured compressor simulator for all active units enrolled in the software. The simulator uses the same calculations and compressor set-up information already in place within Enalysis to simulate the compressor’s performance at operating conditions that you input. The simulator is available 24/7 to run “What if…?” scenarios and provide instant insight into how your compressor will respond to changing conditions. Clear warnings and flags ensure operation will be safe and stable while allowing you to get the most out of your natural gas producing assets. The simulator works with any make, model or vintage of reciprocating or rotary screw compressor.

Enalysis Tip 1.13 - Reciprocating Compressor Performance Optimization

June 10, 2020
In natural gas gathering applications, maintaining the lowest possible suction pressure can provide a significant production advantage. As fields fluctuate and, over time, decline, compressor optimization must be done on a regular basis in order to minimize suction pressure, while maximizing throughput and maintain high levels of overall fleet utilization. Compressor performance curves are a graphical representation of the optimized suction pressure operating range of a compressor given assumed conditions. The flow presented on the curve is the highest throughput that is possible at the specified suction pressure and the power is the total required power consumption for the compression to take place.

Enalysis Tip 1.12 - Reciprocating Compressor Trip and Control Settings

June 4, 2020
This Enalysis Tip details Detechtion Technologies’ recommended procedure for determining the shutdown, alarm and control settings for a reciprocating compressor. Compressor safety shutdown systems consist of pressure, temperature and vibration sensors combined with a set of annunciators and switches. Alarm and shutdown triggers are applied to critical sensors to prevent operating under any conditions that would exceed compressor rated limits. Alarms provide a warning to an operator that a limit is being approached, while triggering a shutdown will immediately cease the operation of the compressor. Therefore, it is essential that each shutdown is set such that the compressor is always protected, while still allowing a sufficient operating range so as not to limit gas production.

Enalysis Tip 1.11 - Reciprocating Compressor Safety Shutdown Systems

June 4, 2020
Changes in operating conditions, such as discharge pressure, flow rate, inlet suction temperature or ambient air temperature, will result in a variations of compressor performance. When the changes are substantial, the mechanical limits of one set of operating conditions may infringe on the normal expected parameters under alternative operating conditions. Therefore, compressors require a safety system designed to shutdown the compressor prior to the breach of any design limit.

Enalysis Tip 1.8 - Troubleshooting Blowby and Gauge Maintenance

May 19, 2020
This post will provide Detechtion Technologies’ recommended steps for troubleshooting Blowby and “Gauge Maintenance”. These two concepts, along with their possible causes, were discussed in detail in E-Tips 1.3 - 1.7.

Enalysis Tip 1.7 - Gauge Maintenance Result for Gas Compressor on Enalysis Report

May 19, 2020
“Gauge Maintenance” is the term used by Detechtion Technologies when the monitored compressor parameters are thermodynamically impossible according to the Enalysis software model. This occurs when the calculated expected discharge temperature is greater than the actual measured discharge temperature for a cylinder.

Enalysis Tip 1.6 - Causes of Blowby: Valve Springing and Lube Rates in Gas Compression Equipment

May 7, 2020
Blowby can result without any physical damage to wear components or unaccounted pressure drops. Improper valve springing can lead to valve flutter, allowing gas to recirculate each compression cycle. Alternatively, high rates of lubrication can lead to oil coating the valve plate and seat, which leads to an increase in pressure differential required to break the stiction when the two surfaces separate. Both are examples of inefficiencies in the compression process and can cause Blowby to flag on an Enalysis report.
