Business Undertakings of Mitsubishi Heavy Industries Engineering, Ltd.

At Mitsubishi Heavy Industries Engineering, Ltd. (MHIENG), engineering is at the core of all of our business, which can be roughly divided into chemical plants, transportation systems and environmental systems (CO₂ recovery systems).
Here we outline the social significance and characteristics of these business areas.

Chemical Plants

Chemical plants are equipment and systems which utilize a starting material, typically oil or natural gas (hydrocarbons), in order to manufacture some products.
At MHIENG, we handle a great variety of plants; the most common types are listed in the table below.

Product (Chemical) Starting Material Use  
Ammonia / Urea Natural gas Chemical fertilizers essential for grain production Contributes to the food supply
Methanol Natural gas Key ingredient in bonding materials, paints and coatings essential as housing construction materials Contributes to the housing supply
Polyethylene Oil Key ingredient in plastics Contributes to the quality and way of life
High-purity terephthalic acid (PTA) Oil Key ingredient in polyester fiber Contributes to the fabric supply
Ammonia Natural gas Key ingredient in acrylic fiber

Chemical plants are made up of a complex and interconnected arrangement of countless pipes, valves, pressure vessels and rotating machines, and every device is part of some essential process. A malfunction in any one of these devices may prevent the plant from being able to produce the product.
Thus, chemical plant construction requires a high level of engineering expertise for designing numerous sophisticated and complex custom-made devices which all connect together organically.
Since the completion of our first fertilizer plant in 1958,MHIENG has delivered numerous fertilizer plants around the world, putting us in contention for the largest share of the global market.
Additionally, in the 1980s we began working with Mitsubishi Gas Chemical Company, Inc. to develop a process for methanol production, and today we deliver large-scale, high-efficiency, energy-efficient and highly reliable methanol plants worldwide.

Through our chemical plants, we help provide food, clothing, shelter and the way of life for people the world over.

Transportation Systems

The guideway vehicles that we casually ride from place to place in daily life depend upon numerous subsystems responsible for vehicles and railway signaling, operation control, electrical power, tracks, platform doors and much more. All of these subsystems must be able to work together correctly to ensure that guideway travel is reliable, safe and on time.
At MHIENG, we serve as a "system integrator" for our customers, designing, procuring and installing each subsystem and then carefully checking that they all operate together as one properly functioning system.

MHIENG's extensive product lineup is tailored to each customer's needs and covers everything from medium- to high-volume traffic transportation systems.

A classic example of a medium traffic volume transportation system is the fully automated driverless Automated Guideway Transit (AGT), which rides on rubber tires.
It is used at major airport hubs in various countries to help ensure travelers are able to transfer smoothly from one terminal to another. The AGT is also used to facilitate daily life in urban settings in Japan, Europe, Singapore and other advanced nations where it is incorporated into core transportation systems as feeder lines.
The cars for the AGT are manufactured in Mihara City, Hiroshima Prefecture, where they also undergo preliminary testing of their automated driving performance at an adjacent testing track. This is part of ensuring system safety and reliability across the entire product life cycle, from design and production to handover and maintenance.

Automation of driving operations has also become a global trend for Mass Rapid Transit (MRT) systems in cities worldwide, with a remarkable example being the Dubai Metro, which was delivered by a consortium led by Mitsubishi Heavy Industries and which is recognized by Guinness World Records as the longest fully automated, driverless metro system in the world.
Additionally, thanks to the engineering project management expertise we have cultivated over many years, Mitsubishi Heavy Industries also headed up the consortium of seven different Japanese companies which built Taiwan's high-speed rail system: the first such high-speed rail system outside of Japan to be built using Japanese high-speed rail technology.

Through systems such as those presented here, MHIENG seeks to use engineering to contribute to further expansion and growth worldwide.

Environmental Systems (CO₂ Recovery Systems)

With concern over global warming growing internationally, Carbon dioxide Capture and Storage (CCS) technologies, which recover CO₂ emitted from fossil fuel combustion and other processes and then store it underground, and Enhanced Oil Recovery (EOR) technologies, which inject CO₂ gas into oil fields in order to improve the efficiency of crude oil extraction, are attracting attention as a means of fighting global warming.

Starting in 1990, MHIENG partnered with Kansai Electric Power Co., Inc. to develop technology for recovering CO₂ from combustion exhaust gas, and we now have the top market share in carbon recovery systems thanks to a total of 14 CO₂ recovery systems—13 commercial-use systems and one demonstration system—which we have delivered to customers around the world.
In 2011, we collaborated with a major power company in the United States to carry out demonstration testing of CO₂ recovery at coal-fired power plants, with the recovered CO₂ then being successfully sequestered underground, leading to subsequent commercial application.
At the end of December 2016, we delivered a CO₂ recovery system having the world's largest recovery capacity at 4,776 tons of CO₂/day. This system helps reduce greenhouse gases by recovering CO₂ from the combustion exhaust gas of coal-fired power plants for later use in EOR processes.

As the leader in CO₂ recovery technology, MHIENG will continue contributing to a brighter future for the entire world.
