Open Rack Vaporizer

Introduction

Open Rack Vaporizer(ORV) is a vaporizer which takes seawater as a heat source,  mainly used for the basic loading huge LNG gasification plant.

Marston Excelsior from England developed ORV. The first ORV is installed on the Canvey Island in England. The largest LNG flowrate is ~200t/h. Previously all Chinese LNG terminals imported ORV from Japan, which was very expensive.

Now we are proud to inform you that our ORV made for Central Petroleum Jingtang LNG Ltd. has successfully operated for 2 years, which has stable performance and can fully replace the high-cost ORV from Japan. We are the only Chinese manufacturer who has successful cases for such high-end vaporizer.

What are The Advantages of Open Rack Vaporizer?

1. Take sea water as the heat medium.

2. Treating capacity is large, and running on a base load. The client could adjust the capacity from 0~100% load range according to different requirements, and the operation is safe.

3. Broadly used for LNG accepting station.

 

Process Flow

The Open Rack Vaporizer uses seawater as a heat source. While LNG goes up inside the panels and seawater flows down over the panel surface (B), seawater heated LNG, and LNG converted to gas.

The benefit of using heat from the seawater is that this energy is for free and there is no further CO2emission for re-gasifying the LNG. It is a typical higher flow LNG vaporizer. The seawater enters the top of the vaporizer and runs over the aluminum tubes. The LNG flows up and is converts from a liquid into a gas. The benefit of using heat from the seawater is that this energy is for free and there is no further CO2emission for re-gasifying the LNG. The water is gathered in the basin at the bottom of the vaporizer tubes before being returned to the sea.
