Mitsubishi Heavy Industries Compressor Corporation (MCO) has received an order from Braskem Idesa, S.A.P.I. of Mexico for five compressors and three steam turbines to be used in a large-scale ethylene production facility which that company is to build locally. The compressors and turbines will be applied to the core process of ethylene production. MCO has a track record in the delivery of this type of equipment to mega ethylene plants having production capacities exceeding 1 million tons per year.
The equipment involves three compressor trains: A charge gas compressor train to compress cracked gas produced by thermally cracking natural gas (the feedstock); and two trains of ethylene and propylene refrigeration compressors, which use ethylene and propylene as refrigerant, respectively. Together the three trains consist of five compressors, three steam turbines to drive the compressors, and auxiliary devices including control systems and condensers. MCO is slated to deliver the compressors and turbines in the spring of 2013. Braskem Idesa’s ethylene production facility will be located within the Coatzacoalcos Petrochemical Complex, in the state of Veracruz, along the coast of the Gulf of Mexico.
GE’s fleet of 47 heavy duty gas turbines operating on low-BTU fuels has accumulated more than 2 million fired hours. Low- BTU, or low calorific value fuels, have lower heating values than natural gas. Examples include syngas, steel mill gases and dilute natural gas. These fuels are lighter than natural gas and have less energy per unit volume. GE’s B, E and F-class turbines operate on low-BTU fuels in a variety of applications, including integrated gasification combined- cycle (IGCC), refinery-based IGCC and steel mills. To achieve the same heat input as natural gas-fired units, low-BTU fuels need increased fuel flow. This flow rate requires the fleet to use GE’s Multi Nozzle Quiet Combustion (MNQC) and standard (single nozzle) syngas combustors.
The hours accumulated by the fleet include projects totaling more than 4 GW of installed power generation capacity at 21 plants. One million of those hours have been achieved on GE’s E-class turbines. Roughly 600,000 hours have been accumulated on GE’s B-class, while the remaining 400,000 hours were amassed on the F-class. Some of the turbines have been running on syngas or other fuels for more than a decade including a large coal-based IGCC facility in Florida and an Italian refinery. Others are newer installations operating at locations in the U.S., Germany, Italy, Canada, Netherlands, Czech Republic, China, Middle East and Singapore.
GE has received a contract for nearly $200 million to supply steam turbines, power generation services and distributed control systems for the conversion of Saudi Electricity Company’s PP10 power plant from simple to combined-cycle operation. The project will add 1,300 MW to the plant’s capacity to support Saudi Arabia’s central region and meet summer peak demands. GE will provide 10 of its SC series steam turbines for PP10. The company previously supplied 40 7EAs for the PP10 site. The combined-cycle conversion enables the plant to increase output without any increase in fuel.
In addition to the SC series steam turbines, GE will supply balance-ofplant mechanical and electrical equipment. An existing simple-cycle Mark Vle integrated control system will be expanded to incorporate the combinedcycle plant. GE power generation services will include installation, testing, commissioning and completing the combined-cycle conversion. Shipment is scheduled to begin in 2013, with services to start in the second quarter of that year. The first two combined-cycle blocks are scheduled to begin commercial operation in 2014, while the full plant will be online by 2015.

Pratt & Whitney Power Systems (PWPS) has been awarded a contract to deliver a 13 MW biomass heat recovery power plant for West Fraser Timber Company in British Columbia, Canada. It will provide power to the company’s Chetwynd Forest Industries plant utilizing two Turboden 65 HRS Organic Rankine Cycle (ORC) turbogenerators. ORC technology utilizes heat fromseveral sources including biomass, geothermal, concentrated solar power, and by recovering heat from industrial processes, engines and gas turbines. It uses an organic fluid instead of steam to drive a turbo-generator, which can range in nominal output from about 1 to 10 MW and up for a single ORC module. The system employs a closed-cycle process that uses relatively low- tomoderate-temperature heat sources to generate electricity. These ORC systems are driven by an evaporation process. Two Turboden 65 HRS systems will be delivered toWest Fraser by the end of 2013, with installation and commissioning expected in 2014.
