Abstract
The seeding of calcium carbonate into a calcium chloride-contaminated monoethylene glycol (MEG) stream accelerates the growth of calcium carbonate particles to a size that enhances their removal from the stream by filtration. A seeding vessel allows the calcium carbonate particles a time period to grow. Sodium carbonate may be added to the contaminated stream to facilitate calcium carbonate particle growth. A recycle seeding conduit may recycle seeds from a filtration unit to the seeding vessel. A base such as sodium hydroxide may be added to accelerate the precipitation process.
