The FloDrip® Wellsite Separator is a compact system designed for removing liquids from a gas stream exiting from a natural gas well. A FloDrip Separation Package can be divided into two primary groups:
- separation packages without gas flow measurement
- separation packages with gas flow measurement
FloDrip® Separation Packages without gas flow measurement are primarily used in gas fields or pools where group measurement practices are approved. Then the main purpose of the package is to remove liquids (produced water) from the gas stream before it enters the pipeline system for corrosion or flow restriction reasons.
FloDrip® Separation Packages with gas flow measurement are primarily used in gas fields where individual well measurement is required. The main purpose of this package is to remove liquids (produced water) from the gas stream in order to increase measurement accuracy. Good measurement practices dictate that accuracy is increased when a substance is measured in only one state: solid, liquid, or gas. Once the liquid is removed from the gas stream and the gas is measured, the liquid can be dumped to a tank or reinjected back into the pipeline after the gas meter. Liquid reinjection depends on many factors, such as the availability of on site storage or pipeline corrosion and flow restriction concerns.
FloDrip® Separation Packages with gas flow measurement are further broken down into five categories based on the package housing style. These styles are as follows:
Enclosure
The Enclosure Style is the original style and is typically provided on the simpler packages. It is used on separation packages with or without metering, and sizes range from 46¨ H x 35¨ W x 21¨ D to 56¨ H x 108¨ W x 27¨ D. Crimtech limits the width to 108¨ wide given that enclosures any wider than this tend to have operation problems with the doors. Packages requiring lengths wider than 108¨ are typically housed in a building.
Enclosure style packages are favored in sour service for safety reasons because this style eliminates confined spaces.
Enclosure Style Example (without gas flow measurement): 8085E Enclosure Style Example (with gas flow measurement): 8145EMP
Building
The Building Style is typically used on packages where extensive instrumentation control is required or more than one FloDrip® vessel is used. Simple package layouts are also housed in buildings where the client's operation staff require shelter from the elements. Buildings vary in size, but typical dimensions are 96¨ H x 72¨ W x 72¨ D with a shed style roof.
Building Style Example: 8145BMPR-050Z
Phone Booth
The Phone Booth Style is used on packages where FloDrip® vessels with extended bodies are used such as the XT8145. This style is very similar to the enclosure style, but rotated 90 degrees to accommodate the larger separator. Typical dimensions are 72¨ H x 48¨ W x 36¨ D complete with a shed style roof.
This is another favored housing style in sour service due to its limited access to enter the enclosure.
Phone Booth Style Example: 10075PMPR-050Z
All the above styles combine very well with the PlasTank™ produced water storage tank and a chemical tank (PlasTank™ CT420) on one common skid. This combination unit is very popular due to its low cost of installation and ease of transportation.
Wellhead
The Wellhead Style is a variation of the building style used on packages where the building slips over top of the wellhead. This way, the wellhead, separation equipment and sometimes the pipeline equipment are housed within one common building. Buildings vary in size but typical dimensions are 96¨ H x 120¨ W x 72¨ D with a shed style roof.
Built with a floor or without, this style offers superior freeze protection to the wellhead and pipeline equipment. Clients have reported large operation cost savings because methanol injection rates are significantly reduced or eliminated in some cases.

None
There are times when no housing is required at all. This is because the FloDrip
