Mercury & Heavy Hydrocarbon Removal Units

1.Product Overview

Mercury & Heavy Hydrocarbon Removal Units are specialized treatment systems designed to remove trace mercury and heavy hydrocarbons from natural gas streams.

These units are primarily applied in gas processing and LNG pre-treatment facilities to protect downstream equipment and ensure long-term system reliability.

2.Function & Purpose

The main function of these units is to eliminate harmful contaminants such as elemental mercury and heavy hydrocarbons from natural gas.

Mercury removal is essential to protect aluminum heat exchangers and cryogenic equipment, while heavy hydrocarbon removal helps prevent condensation, fouling, and operational issues in low-temperature processes.

3.Typical Configuration

Mercury and heavy hydrocarbon removal units are typically supplied as skid-mounted systems incorporating adsorption vessels.

A standard configuration includes one or more treatment vessels filled with specialized adsorbent materials, along with inlet and outlet piping, monitoring instruments, and bypass arrangements for operational flexibility.

4.Applicable Gas Sources

These treatment units are suitable for natural gas sources that require stringent gas quality control, including:

• Pipeline natural gas

• Wellhead gas

• Coalbed methane

• Shale gas

They are most commonly applied upstream of LNG liquefaction systems and other cryogenic or low-temperature gas processing facilities.

5.Design Features & Advantages

• Effective removal of trace mercury to protect aluminum-based equipment

• Reduction of heavy hydrocarbons to improve low-temperature process stability

• Proven adsorption technology with reliable performance

• Skid-mounted modular design for compact layout and easy installation

• Adsorbent materials selected based on gas composition and project requirements
