We provide complete satellite stations, including direct vaporizing and mixing facility (DV&M system) in which (gaseous) natural gas and liquid propane or butane are directly mixed to adjust the calorific value of the gas product, as well as peripheral plants.

A city gas plant is where natural gas (LNG), which is mostly methane, is mixed with propane and butane to achieve the desired energy content, for the reliable supply of city gas. We provide plants with the latest technology for directly mixing LNG with liquid propane (LPG), for energy-content-adjustment.
Japan has over 20 LNG terminals, where LNG arrives from overseas. City gas manufacturing facilities are needed in places where city gas usage sites are not connected by pipeline to an LNG terminal. Such facilities are called LNG satellite plants, and they consist of small facilities for small-storing, gasifying and adjusting the calorie of the gases transported from the LNG terminal. All these facilities put together make up an LNG plant.
Hitachi provides the full range of facilities needed at an LNG plant, including LNG storage tanks, LNG gasification equipment, LPG storage tanks, pressure vaporization equipment and energy-content-adjustment equipment. We have a great deal of experience in this area, particularly in energy-content-adjustment equipment, and our customers can use our products with confidence.
Capital manufacture and install LNG plant energy-content-adjustment equipment, as well as undertaking complete EPC contracts.
For customers in the following types of gas business.

The DV&M systems we have developed originally used separate processes for gasification of LNG and LPG, and then mixed the gases to adjust the calorie. Now however, we offer a separate process where LPG in its liquid state is added to City gas, and the mixture is then gasified and its energy content is adjusted. This method has been well received for its ease of operation and control, and its lower running costs.
