Amine Sweetening Units

amine sweetening plant design

Modular Amine gas sweetening units using most common aqueous amine solutions to remove hydrogen sulfide (H2S) and carbon dioxide (CO2) from natural gas streams.

Read More

Dew Point Control Units

Modular Hydrocarbon Dew Point Control Units designed to inhibit the formation of solid hydrates in natural gas streams by chemical (methanol) injection, separation (membrane), or mechanical refrigeration.

Read More

Field Oil Stabilizer Units

condensate stabilization unit

Modular crude oil stabilizer units to reduce the vapor pressure of light crude oil streams making the crude safer to transport while recovering the valuable light ends.

Read More

Fuel Gas Conditioning

Modular Fuel Gas Conditioning units designed to protect natural gas fueled engines and turbines from liquid slugs, solids (< 0.1 microns) and liquid aerosols.

Read More

Glycol Dehydration Units

TEG dehydration unit

Modular Glycol dehydration units for the removal of water from natural gas and natural gas liquids (NGL) using TEG.

Read More

JT Plants

modular JT plant unit

JT Plants Modular Joule-Thomson (JT) units condition gas for pipeline transmission by removing hydrocarbon liquids using a drop in gas pressure, which allows the gas to expand, to create a cooling effect. The unit condenses heavy hydrocarbons out of the gas to meet required gas pipeline specifications. Excess liquids that may condense and cause problems in transmission are recovered and stored.

Read More

Line Heaters

Modular indirect fired heaters to transfer heat to a hydrocarbon (oil or gas) for improved combustion or separation by natural convection.

Read More

Membrane Gas Separation

Modular gas separation by utilizing membranes for removal of water, CO2, H2S, nitrogen, and heavy hydrocarbons.

Read More

Regulator Skids

natural gas pressure reducing station design

Modular Natural gas pressure regulation units to regulate and meter the gas supply needs for pipelines, gas turbines, and other natural gas users.
