中国石化新闻网讯 据Oil & Gas Journal网站7月15日报道 休斯顿量子能源合作伙伴投资组合公司PetroLogistics ll LLC已与陶氏化学签订合同,为将在美国海湾沿岸建造的丙烷脱氢(PDH)装置提供技术许可。
PetroLogistics表示,年产50万吨的PDH装置将配备陶氏专有流化催化脱氢(FCDH)技术,该技术采用基于流化催化裂化的新型反应器设计,用于生产专用丙烯。
虽然还没有决定对项目位置进行评估的美国海湾沿岸的两个备选场地,但PetroLogistics确实确认其目前正在参与拟议PDH工厂的前端工程设计。
宣布该工厂之前,PetroLogistics在北美建造了第一个用于生产丙烯的PDH工厂,该工厂于2010年在其休斯顿船舶通道站点开始运营。
PetroLogistics总裁内森·蒂卡奇表示:“自第一个PDH工厂启动以来,页岩革命相关的发展导致从历史上供应美国大部分丙烯的来源(石油精炼厂和重原料乙烯裂解炉)生产的丙烯产量大幅下降。”
因此,未来丙烯需求的增长将主要通过丙烷脱氢来提供。然而,新的PDH项目进入美国市场的速度缓慢,主要是因为与现有PDH技术的资本成本和效率相关的挑战。蒂卡奇表示:“我们已经与陶氏公司合作了3年,对FCDH技术进行了评估,我们相信它能够解决这些挑战,并代表着PDH过程中的重大突破。

PetroLogistics plans US Gulf Coast PDH plant
PetroLogistics ll LLC, a portfolio company of Quantum Energy Partners, Houston, has let a contract to Dow Chemical Co. to provide technology licensing for a propane dehydrogenation (PDH) unit to be built on the US Gulf Coast.
The 500,000-tonne/year PDH unit will be equipped with Dow’s proprietary fluidized catalytic dehydrogenation (FCDH) technology, which uses a novel reactor design based on fluidized catalytic cracking for on-purpose propylene production, PetroLogistics said.
While it has yet to decide between two alternative USGC sites under evaluation for the project’s location, PetroLogistics did confirm it is currently engaged in the front-end engineering design for the proposed PDH plant.
Announcement of the plant follows PetroLogistics’ construction of the first PDH plant in North America for on-purpose propylene production, which began operations at its Houston Ship Channel site in 2010 (OGJ Online, Sept. 4, 2018).
“Since [start-up of that first PDH plant], developments related to the shale revolution have resulted in a significant decline in coproduct propylene production from the sources that historically supplied the majority of US propylene: petroleum refineries and heavy feed ethylene crackers,” said PetroLogistics Pres. Nathan Ticatch.
“As a result, future growth in propylene demand will need to be supplied largely via on-purpose propane dehydrogenation. However, new PDH projects have been slow in coming to market in the US primarily because of challenges relating to capital costs and efficiency of incumbent PDH technologies. We have been working with Dow for 3 years in evaluating the FCDH technology and we are confident that it addresses those challenges and represents a significant breakthrough in the PDH process,” Ticatch said.
