Process equipment
Hitachi Zosen is a of the leading manufacturer of pressure vessels and heat exchangers for refineries, petrochemical plants, fertilizer plants, and industrial plants such as seawater desalination plants and pulp plants. We contribute to meeting the ever-increasing demand for world energy by supplying reactors to the Refinery Upgrading Project, which produces gasoline and diesel oil from heavy crude oil sand projects and gas-to-liquid projects and among others. In addition, we contribute to securing food and water for growing populations in developing countries by supplying equipment to fertilizer plants and desalination plants.
Major products
Reactors
We manufacture desulfurization reactors, made from chrome molybdenum steel, which is our main product, along with CCR reactors, FCC reactors, ammonia converters, and other items. Furthermore, we are one of the leading manufacturers of plate construction reactors with vanadium-enhanced chrome molybdenum steel. We are proud of our prominent welding techniques and process technologies that enables us to deliver high-quality reactors within a reasonable time frame.
Heat exchangers
We manufacture high-pressure heat exchangers for oil refining plants, large-scale heat exchangers such as methanol reactors and EO/EG reactors, and high-pressure heat exchangers for fertilizer plants. Our Maizuru Works has supplied many heat exchangers to customers all over the world, and is famously known as "Maizuru - the home of heat exchangers".
Others
We manufacture FT reactors, which are the key processors in gas-to-liquid plants. We also manufacture adsorbent tower internals for paraxylene plants, as well as towers, columns, drums, and mixing vessels for various kinds of process plants.
