天然气制合成油得到的柴油燃料基本不含硫和芳烃 ,费—托法合成技术的进步已使天然气制合成油(GTL)的生产成本可与 18~ 2 2美元 /桶的原油价格相竞争 ,因而GTL已成为天然气 ,尤其是偏远地区天然气高效利用的一个有前景的途径。GTL技术由合成气生产、费—托合成和产品精制三部分组成。GTL的工艺方案有埃克森公司AGC - 2 1工艺、壳牌公司SMDS工艺、萨索尔公司Synthol工艺、合成油公司工艺等。GTL技术在合成气生产和费托合成方面还出现了一些新的进展。 2 1世纪将迎来GTL装置新的发展期 ,在未来 15年内 ,预计GTL装置生产能力将增加 (45 0 0~ 6 75 0 )× 10 4 t/a。 2 0 0 5年前将有 7套GTL装置投运 ,总能力 880× 10 4 t/a。 相似文献

由于对环境保护的关注,GTL(Gas to Liquids)迎来了发展机遇。GTL既可以从天然气液化,又可以从固体炭气化转化为液体。加工劣质油的炼油厂可以采用渣油/焦炭/沥青气化,然后F-T合成为清洁油品,同时实现清洁生产。对于能够获得天然气的炼厂,则应尽量利用天然气。 相似文献

Gas-to-liquids (GTL) technology involves the conversion of natural gas to liquid hydrocarbons. In this article, theoretical studies have been presented to determine the feasibility of transporting GTL products through the Trans-Alaska Pipeline System (TAPS). To successfully transport GTL through TAPS, heat loss along the route must be carefully determined. This study presents heat transfer and fluid dynamic calculations to evaluate this feasibility. Because of heat loss, the fluid temperature decreases in the direction of flow and this affects the fluid properties, which in turn influence convection coefficient and pumping power requirements. The temperature and heat loss distribution along the pipeline at different locations have been calculated. Fairly good agreement with measured oil temperatures is observed. The powers required to pump crude oil and GTL individually, against various losses have been calculated. Two GTL transportation modes have been considered; one as a pure stream of GTL and the second as a commingled mixture with crude oil. These results show that the pumping power and heat loss for GTL are less than that of the crude oil for the same volumetric flow rate. Therefore, GTL can be transported through TAPS using existing equipment at pump stations. 相似文献

Rising prices for oil were supposed to have made the synthesis of petroleum liquids from natural gas via a gas-to-liquids (GTL) more attractive. Instead, many developments appear to be on hold. Part of the reason has been the rising capital cost of GTL plants. There have also been problems with the new technology. 相似文献

As more and more countries announce plans for gas-to-liquids (GTL) units, the US is planning to use the same technology to produce liquids from coal. GTL normally requires the feedstock to be available cheaply, but gas prices have been rising sharply in recent months, especially in the US. Coal, on the other hand, is much cheaper. Another potential source of cheap feedstock is heavy residues produced in refineries. Here, though, the opposite is also planned: the conversion of liquids into gas. 相似文献
