Abstract: The present invention provides an in-reactor solution that avoids costly blending and the use of metallocene elastomers. The inventive Ziegler-Natta polypropylene composition also includes additional components that may improve properties relative to a metallocene catalyzed elastomers. The invention is a clear impact polypropylene composition that is made in-reactor with Ziegler-Natta catalyst, and is suitable for a wide range of processes. Unlike other clear impact copolymers, it does not rely on high-shear processes or compounding with elastomers. The invention uses conventional polypropylene reactor technology to produce these compositions.

Abstract: A steam supply apparatus (1) for enhanced oil recovery from an oil field (10). The steam supply apparatus includes a water circulating portion (50) providing a continuous flow of water to a water heater (4) for the production of a mixture of steam and water, and a separator (5) for directing the steam to the oil field. Water returned from the oil field is purified in a water treatment apparatus (3) to provide make-up water to the water circulating portion. A buffer volume (3b) is provided in fluid communication between the water treatment apparatus and the water circulating portion. The buffer is sized to provide a time lag between a degradation of the quality of the purified water and an occurrence of an unacceptable scale production in the water heater, thereby allowing continued safe system operation until the water quality problem is corrected.
