问题 问答题

CYCLMAX的隔离系统主要有什么作用?

答案

参考答案:

隔离系统是使再生器内的环境与再生段的其余部份相隔离,再生器是含氧环境,再生段的其余部份则是氢/烃环境,隔离系统防止了这两种环境可能混合的潜在的危害性。有两组隔离系统,待生催化剂入口至再生器是待生催化剂隔离系统,它隔离了再生器和反应器。再生器的催化剂出口是再生催化剂隔离系统,它隔离了再生器和闭锁料斗。两组隔离系统很相似,都有一个“高压区”,两个隔离阀,一个加压阀和一个差压控制阀,还有两只差压控制器,顶部控制器位于高压区和其上方的容器之间,底部控制器位于高压区和其下方的容器之间。待生催化剂系统设有低差压控制器。因为可以假定,分离料斗的压力始终高于再生器的压力。

Exploit your parking space

An unused parking space or garage can make money. If you live near a city center or an airport, you could make anything up to £200 or £300 a week. Put an advertisement(广告)for free on Letpark or Atmyhousepark.

Rent(出租)a room

Spare room? Not only will a lodger(房客)earn you an income, but also, thanks to the government-backed “rent a room” program, you won’t have to pay any tax on the first £4500 you make per year. Try advertising your room on Roomspare or Roommateeasy.

Make money during special events

Won’t want a full-time lodger? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money, Grashpadder can advertise your space.

Live on set

Renting your home out as a “film set” could earn you hundreds of pounds a day, depending on the film production company and how long your home is needed. A quick search on the Internet will bring up dozens of online companies that allow you to register your home for free—but you will be charged if your home gets picked.

Use your roof

You need the right kind of roof, but some energy companies pay the cost of fixing  solar equipment(around£14,000), and let you use the energy produced for nothing. In return, they get paid for unused energy fed back into the National Grid. However, you have to sign a 25-year agreement with the supplier, which could prevent you from changing the roof.
