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.

MSAPR - 2019 Schedule 9 and Schedule 10 Reports Due July 1, 2020

June 12, 2020
The 2019 reporting deadline is fast approaching for the submission of the Schedule 9 and 10 reports for part 2 of Canada’s Multi-Sector Air Pollutants Regulations (MSAPR). If you have yet to submit those reports, you still have time to get them in by July 1, 2020. If you have not had the chance yet to talk to a member of the Detechtion team regarding MSAPR and Detechtion's solution built into the Enalysis software, reach out and we will be happy to assist you. Otherwise, below is a helpful reminder on the types of details you should be aware of for the corresponding reports.

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 1.6 - 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.

Enalysis Tip 1.4 - Causes of Blowby in Compressor Enalysis Reports: Damaged Cylinder Wear Components

May 4, 2020
As mentioned in the last E-Tip, “Blowby” is a term used by Detechtion Technologies to quantify inefficiencies in the compression process. Blowby is an indication of the health and efficiency of the valves and piston rings inside every cylinder. In short, it is a measure of the number of molecules of gas that are being re-circulated and recompressed within a cylinder. As more gas is re-circulated and recompressed, the temperature rise across the cylinder increases, more horsepower is required and the cylinder’s capacity to compress gas decreases. There are several things that can result in Blowby to flag on an Enalysis report. This article focuses on the effect of damaged cylinder wear components. While the most common culprits are valves and piston rings, this also includes piston rod packing, VVCP seals, valve gaskets, etc. Essentially, any component that is meant to prevent the passage of gas under normal working conditions, could lead to Blowby when it becomes damaged.

Enalysis Tip 1.1 - What is Enalysis?

April 27, 2020
Enalysis is a web-based predictive SaaS (Software as a Service) program combining geometric software models of compressors and thermodynamic principles to analyze operating data and accurately calculate all relevant compression KPIs for reciprocating and screw compressors. Highly developed proprietary algorithms are used to determine the exact operating status of a compressor and each individual cylinder from both a production and maintenance viewpoint.

MSAPR Compliance - Sink or SWIM

November 27, 2019
Performing emission tests and reporting those results to SWIM is a major part of achieving compliance with MSAPR, and with the help of some explanatory material from Environment Canada and Enalysis®, we have the tools to help! Environment and Climate Change Canada hosted a session in Calgary, Alberta on November 19 and 20, 2019 to provide an overview of the MSAPR regulations and answer questions from industry. Questions ranged from allowable testing procedures, compliance approaches between subset and subgroup, penalties for non-compliance all the way to questions surrounding detailed timelines for testing.

Why would my Engineering Account Manager be telling me to lower my suction pressure and pull down the field?

September 18, 2019
A gas gathering system can be confusing when you consider all the different competing variables and goals. In this post, let’s look at a common question you might have when first looking at a compressor curve. On the Min Max curve below (provided in combination with a Startup Package for a specific running configuration), we can easily see that as the suction pressure (horizontal axis) increases, the maximum achievable flow rate (vertical axis) increases. For a compressor running at a constant configuration (cylinder configuration, pocket positions and running speeds constant) as flow rate is increased, the suction pressure increases:
