What our products and service?
Compressors and turbines are one type of "turbomachinery." While it is somewhat difficult to provide a precise engineering definition of this term, one description is "a machine which performs continuous energy conversion between fluid energy and mechanical energy by means of a rotating impeller." Machines that we use everyday, such as fans, propellers, turbines, pumps, water wheels, windmills, jet engines, and automobile turbo chargers are all types of turbomachinery. The turbomachinery manufactured by Mitsubishi Heavy Industries Compressor Corporation (MCO) used for the gas and petrochemical industries of these machines. Specifically, these products include the compressors which compress the air and gas necessary for production at production facilities such as chemical plants, gas plants, and steel works, as well as the steam turbines which drive these compressors. These products are active in energy industry and petrochemical industry fields all over the world. The rotors we produce range up to diameters of over 2 meters and weights exceeding 10 tons. MCO possess the world-leading design and production technologies that are needed to ensure high-speed and stable operation of these rotors.
Applications of MCO products
MCO’s compressors and steam turbines are installed in;
- various kind of chemical plants (including refrigeration system) such as ethylene plants and fertilizer plants (ex. SABIC)
- oil & gas field such as refinery, LNG plants, gas production facilities and gas pipelines (ex. ARAMCO plants)
MCOSA Products
Ethylene Plant
Ethylene plant compressors
These compressors generate high horsepower and are the largest compressors produced by Mitsubishi Heavy Industries Compressor Corporation. This type of single-shaft, multi-stage compressors forms the heart of a petrochemical plant. Compressors for ethylene plants are ordinarily a compressor train of one of three types: compressors for charge gas, for ethylene gas, or for propylene gas. (These multiple compressors are connected to a steam turbine which drives them.)
Ethylene plant steam turbines
The scale of ethylene plants has continued to grow in recent years, and MCO is developing steam turbines with larger capacities in order to meet the needs of these larger plants.
The photo at rightbelow shows the shop test of Charge gas compressor train for an ethylene plant producing 1.5 million tons per year. When used as a mechanical drive turbine, the steam turbine provides a maximum output of 95 MW within MCO.
In order to meet the needs of further plant growth in the future, MCO has installed shop test facilities for ethylene plant compressor trains in the 2 million tons/year class.
MCO has completed technical development that includes (1) development of casings for large capacities, high temperatures, and high pressures, and (2) development of large-capacity and high-load blades, and we are planning to apply these developments to commercial steam turbines in the future.
Methanol Plant
Compressor for methanol gas synthesis
As methanol plants expand in size, as do the corresponding synthesis gas compressors.
Synthesis gas compressors are essential to the success of a methanol plant so in order to meet such critical needs of plant owners, MCO has developed technologies for highly efficient, large centrifugal compressors and steam turbines.
- synthesis gas compressor driven by a double-end drive steam turbine which was delivered to Saudi Arabia.
- compressor driven by a steam turbine which was delivered to Guinea.
Methanol Plant Steam Turbines
As methanol plants expand in size, as do the corresponding synthesis gas compressors which are at the heart of these plants. Many large-capacity steam turbines use double-flow types for the exhaust rotor casing.
However, MCO uses a single-flow type exhaust rotor casing that makes use of titanium alloy rotor blades in the low-pressure turbine, resulting in a more compact design.
