关于节流效应制冷量的问题? 节流的本质是压缩机段间冷却水的带走的那部分能量,开大循环压缩机,必定要加大循环水量,带走更多能量,制冷量应该会增加。建议你看一下节流制冷效应(不是节流制冷,而是节流制冷效应)的本质。查看更多

shell气化炉低压投煤的后果? 与低压启动激冷气压缩机有什么关系呢 scgp激冷气压机大多采用单级悬臂离心式,其流量特性与压力相关性较大 满足投煤时激冷气流量应等于或稍大于热气流流量需要达到一定的压力和转速 另一方面,设计或制造没有问题的单级悬臂离心式压缩机在启动时为平衡轴向力是有最低启动压力要求的 一般来说,6~8bar的压力下投煤,是可以较好地平衡上述要求的,也没神马不可接受的危害 当前某些scgp厂家在极低压力下启动激冷压机是有其不得已的苦衷的 考虑sub问题(更多的是信心),提前投煤只要把握住核心要点,应该也是没神马问题的查看更多

美国不选煤制油的理由.? 这是从国外网站上找到的相关消息。 我在transgas官方主页上仔细看了一下,采用的过程是煤—合成气—甲醇—汽油,采用的是mtg过程,气化技术下面也说了,是采用uhde的煤气化技术。mtg没看到是用哪家,难道是exxon-mobil的。 15/12/2008 - west virginia selected as site for new coal-to-liquids plant charleston, w.va, u.s.a. — transgas development systems llc (tgds) plans to build a coal-to-liquids plant in west virginia, company officials announced today during the west virginia energy summit. tgds has filed a permit to build the $3 billion facility in mingo county. “west virginia remains firmly committed to advancing coal-to-liquids technology. we are excited that transgas development systems shares that goal and is prepared to invest in our state,” said gov. joe manchin. “the decision to construct this coal-to-liquids plant will encourage more efficient use of our coal, help create more job opportunities and will continue us on our path to secure a more stable and independent future in energy.” projected to be operational by 2013, the plant will be built in mingo county’s new energy park near gilbert. the construction phase is expected to generate 3,000 jobs. when fully staffed, the facility will employ as many as 200 workers. tgds estimates the facility will use up to 3 million tons of locally mined coal a year to produce more than 6.5 million barrels of gasoline. “as a supporter of coal-to-liquid technology and west virginia coal, i am pleased to see this latest effort taking shape in mingo county,” said sen. robert c. byrd. “this project has the potential to bring many well-paying coal jobs to west virginia, and that is always good news for our state.” “what we need are serious initiatives that put west virginia coal at the forefront of meeting our nation’s energy needs, while also creating good jobs and making meaningful investments in our state,” said sen. jay rockefeller. “west virginia needs to focus on projects that will deliver and put us on a path toward a promising energy future that i know we can and will achieve through tomorrow’s clean coal.” “america’s need for energy is continuing to grow and the path toward a better, more diverse energy future in america must include coal as a major player, along with renewables,” said rep. nick j. rahall ii. “for years i have worked to help clear the way for coal to address our energy challenges more cleanly, efficiently, and affordably, and this new west virginia plant will help to fulfill that goal. southern west virginia, deep in the heart of our nation’s coal country, is the perfect place to help jumpstart a national coal-based liquid fuels industry.” tgds has signed a licensing agreement with uhde corporation of america for the use of the new prenflo gasifier reactor. the proprietary technology is under authorized license from uhde gmbh, germany. the prenflo technology handles all types of coal as well as petroleum coke, char and biomass. in addition to producing gasoline, the gasification process produces economically valuable by-products such as slag and fly ash used in construction. based in germany, uhde is one of the world's leading engineering companies in the design and construction of industrial plants. “coal must be a central part of our nation’s energy future and with such a high-profile investment in coal-to-liquid technology this new plant will help ensure that is the case,” said rep. shelley moore capito. “this is an exciting announcement for our state, and it will be a clear example of the important role west virginians and coal-to-liquid technology can play in making our nation more energy independent.” the facility will be served by two 1,000 mwth prenflo gasifiers in the direct quench version (pdq). the facility will use a catalytic process to produce gasoline. tgds worked with the west virginia development office and the mingo county redevelopment authority (mcra) to develop the project. “this is the most exciting day ever for mingo county,” said mike whitt, executive director, mcra. “we thank gov. manchin for referring transgas to mingo county. we look forward to working with the governor and transgas to bring this project to fruition.” west virginia department of commerce 90 maccorkle avenue sw south charleston west virginia wv 25303查看更多

英格索兰压缩机图片(有更新,15楼呆哥奉上高清美图)? 英格索兰压缩机与其它品牌特点: 1,垂直刨分。筒内设高效换热器,节约安装空间,但是常见的问题是水处理不好造成换热器效率下降,这种换热器比常规的列管式换热器难以处理。水侧布管太密,气侧还有管内翅片 2,叶轮,配重等以三角圆弧形式热装,力矩传递好,结构轻 又:15楼图片中有一个“气体过滤网”,应该有误,实为“破雾网”,作用在于把气体中的过饱和蒸汽凝结下来,从疏水器中排出,防止带入下一级,这是由于其换热器的气侧空间太小。而且,这个破雾网也是一个麻烦事,经常会被空气中的灰尘,以及钙垢等杂物堵塞,需要拿下清洗。 个人意见,仅供参考。不喜勿喷。查看更多
