MarkWest Energy Partners, L.P. announced the resumption of operations at its Houston processing and fractionation complex ('Houston complex') in Houston, Pennsylvania. As previously announced, the Houston complex was shut down following what appears to be a weather related incident that occurred on the evening of May 28, 2014.
The Houston complex consists of three processing plants totaling 355 million cubic feet per day (MMcf/d) and 98,000 barrels per day of ethane and heavier fractionation capacity. An engineering assessment and inspection of the Houston complex's facilities and equipment has indicated that the incident was isolated to a heat exchanger that is required for the operation of Plant III. Plants I and II and all of the fractionation units have safely been returned to operation. Plant III will remain shut down in order to complete repairs.
