What is a horizontal separator?

A horizontal separator is a vessel for the bulk removal of liquids or solids by gravity. Operators prefer to utilize a horizontal separator over other separators when the well streams have large liquid to gas ratios, constant flow, and small liquid surge characteristics (high liquid/ gas). Other reasons could be when work areas have vertical height limitations or horizontal separators are smaller and less expensive than vertical separators for a given gas capacity or well streams experiencing foamy production or well streams requiring three-phase separation applications with more efficient liquid-liquid separation. These separators may go by many names like horizontal separators, oil-water separator, three-phase separators, two-phase separators, but functionality is all relatively the same. With these reasons, it is important to have properly functioning parts because without them it is just a pressure vessel.

What parts go to a horizontal separator?

CROFT Supply.com focuses on parts that are utilized for separators dedicating an equipment category for all parts utilized for separators. Below you will find a brief description of the separator parts available on Croft Supply: 

1.Liquid Level Controllers - Liquid level controllers maintain the desired level in a vessel. The displacer floats in the process fluid and as the fluid level passes to the high-level set point. The liquid level controller pilot sends signals to the dump valve to open. As the level decreases and reaches the low-level set point the pilot stops send supply gas to the dump.

2.Dump Valves - A dump valve is opened by the controller to drain the liquids from a vessel. 

3.Gauge Valve Sets - These valves are used when replacing a broken sight glass to isolate process fluid.

4.Sight Glass - A sight glass is a transparent glass tube that allows you to see the process fluid level inside a vessel. 

5.Temperature Gauges - Temperature gauges are designed to show process temperature.

6. Thermowell - Thermowells are designed to block the process fluid and to be a connection port for temperature gauges.

7.Pressure Gauges - Pressure Gauges are designed to show process pressure.

8.Vent Caps - Vent caps are used to protect the PSV from rainwater. This vent cap also has a whistle vent integrated for low amounts of pressure-relieving that is usually not noticeable.

9.Pressure Safety Valves -The pressure safety valve  will open if process pressure exceeds the factory set pressure. The PSV ensures the safety of the equipment.
