Oklahoma City — LSB Industries Inc. said May 29 that its subsidiary, Pryor Chemical Co., has purchased a group of chemical plant components for $6.5 million. This equipment is intended to improve the operation and efficiency of its ammonia plant in Pryor, Okla., and for possible use at certain of its other chemical facility locations. Previously, this equipment was in operation at a chemical production facility in the U.S. LSB said over the next six-to-eight months, it expects to move the equipment from its current location to its appropriate chemical facilities for installation and to shops for refurbishment. The cost to transport, install, and refurbish this equipment has not yet been determined. LSB funded the purchase and intends to fund the other associated costs associated from its working capital.
