OLEFIN production plants are unique in the fact that they can accommodate a variety of feedstocks to produce ethylene, propylene, and butadiene. Yields of these three main products will vary depending on the feedstock used. An olefins plant consists of three main areas: a hot section, where the reaction takes place; a compressor section, that provides the necessary pressure to move feedstock through the plant and provide refrigeration; and the recovery section, where product is distilled at low cryogenic temperatures can be found. Regardless of feedstock or technology used, there are several key control valve points that are an essential part of plant operations.
