Enalysis Tip 1.19: Compression Basics 3 – Reciprocating Compression Cycle

December 17, 2020
The first part of our Compression Basics series, Gas Properties, introduced key principles and the gas compression laws. It concluded by showing how gas properties and laws can be used to explain the effects of suction pressure and suction temperature on compressor throughput. The second part of this series looked at the role compression plays in natural gas production and provided some background information on two of the most common types of compressors used in natural gas gathering, the reciprocating compressor and the rotary screw compressor.

Enalysis Tip 1.18: Natural Gas Compression Basics 2 – Why Compression

September 23, 2020
One of the many challenges of natural gas production is that natural gas reservoirs rarely reside in areas of dense energy consumption. Often, the hydrocarbon resources are in incredibly remote locations and the challenge then becomes how to safety transport this valuable resource so that it can be used to power our cities, factories, homes or be exported as LNG.

Enalysis Tip 1.17: Natural Gas Compression Basics 1 - Gas Properties

September 16, 2020
In this E-Tip, the second in our Compression Basics series, we will explore some basic gas properties to see how gases respond to changes in pressure and temperature and what that means for the amount of gas that can fit in our compressor at suction conditions.

Enalysis Tip 1.16: Natural Gas Compression Basics – An Introduction

August 10, 2020
This E-Tip is the first in a series that will cover the basics of natural gas compression. While compressors are complex machines, this series will strive to simplify the key concepts of concern when dealing with the compression of natural gas in a reciprocating or screw compressor. From the basics of the relationships between volume, pressure and temperature of a gas, this series will develop an understanding of capacity and power for compression and the key variables that influence both.

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 1.10 - Reciprocating Compressor Limitations

June 1, 2020
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.
