摘要:

探讨了与合成氨、尿素装置配套的煤气化装置升级改造中加压气化工艺与常压气化工艺的主要差别。在优惠政策取消的情况下,常压固定层气化工艺已不具备竞争能力;从运行成本、能耗、人工、自动化等多方面考虑,与合成氨、尿素装置配套的煤气化装置必须向大型加压气化工艺方向发展。

Abstract:

The main differences between pressuried gasification and atmospheric gasification in upgrading of coal gasification plant which is matched with ammonia and urea units are discussed.Under condition of cancellation of preferential policies, the atmospheric fixed-bed gasification process does not possess competitive capacity; considering from many respects such as operating cost, energy consumption, manpower and automation, etc., the coal gasification plant for ammonia and urea units must develop towards the direction of large-scale pressurized gasification process.
