CB&I supplies dew point control plants that use straight refrigeration to remove heavy hydrocarbons from natural gas streams. We've designed and built dew point plants that range in size from 80 to 200 million standard cubic feet per day.

Complete design-build services. We provide a true EPC solution for the installation of dew point plants, performing the work from start to finish with our in-house resources and providing a lump-sum price for the project. Our capabilities include conceptual design, detail engineering, procurement, fabrication and construction as well as startup and operator training. We offer a single-point solution for new plant installations, as well as retrofits and expansion projects, and we can integrate our dew point plants with our gas treating plants.

We design refrigerated plants with dew point temperatures ranging from 20°F to -30°F (-6°C to -35°C). The optimum temperature depends on the capital and operating costs associated with hydrocarbon recovery. Lower dew point temperatures are preferable when butane and heavier hydrocarbons can be recovered cost-effectively.

Effective dew point control. Our plants utilize propane or Freon straight refrigeration systems to remove liquids from the gas stream. Straight refrigeration provides a cost-effective alternative to other types of liquids recovery plants and can be used in remote locations where a liquid pipeline is not available. Another advantage of straight refrigeration systems is that they typically use ethylene glycol injection instead of more expensive molecular sieve systems. They also limit the pressure drop on the gas stream, so no residue compression is needed.

We can design and construct gas processing plants anywhere around the world, even in the most logistically challenging circumstances. Our global engineering, procurement, fabrication and construction resources can be mobilized to virtually any location and, depending on the project requirements, we can build plants utilizing either modular or conventional construction methods, or a combination of both.
