Method and apparatus for maximizing the productivity of a natural gas liquids production plant |
摘要 |
An objective in a natural gas liquids (NGL) plant is that of achieving and maintaining maximum productivity. If this plant is equipped with a turboexpander that drives a gas compressor (recompressor), maximum turboexpander productivity provides maximum plant productivity attained by maximum compressor power. This is accomplished by manipulating the compressor operating point location ( by adjusting the opening of the antisurge valve) and by controlling rotational speed. The subjects of the proposed invention are the method and apparatus (comprising a turboexpander/recompressor rotational speed controller and a recompressor antisurge controller) providing maximum turboexpander/recompressor rotational speed and recompressor operating point location (corresponding to maximum power) by opening the turboexpander's adjustable nozzles and the recompressor antisurge valve.
