Waukesha Engines Power Peruvian Pipeline Project
The three-part project, which began commercial operation in 2004, includes extracting natural gas and natural gas liquids from the Camisea site in the interior of the Peruvian jungle 431 km (267 miles) east of Lima; moving it by pipeline over the Andes and down to the coast for processing, and then north along the coast to Lima for distribution to industrial and power generation facilities.
Two parallel pipelines (one for natural gas and the other for natural gas liquids) - each hundreds of miles long – snake their way from the jungles up and over the mountains and down to the coast. Moving the natural gas liquid over the mountains at a rate of 50,000 barrels per day required the construction of four pumping stations -- one at 377 m (1,256 ft.) above sea level, the second at 1,626 m (5,420ft.), the third at 2,960 m (9866 ft.) and the fourth at 4,105m (13,683 ft.). Sixteen Waukesha engines were specified for the initial phase of the project - eight to drive the pumps and eight engines units - two each, for each of the four pumping stations. Reliability and versatility were key considerations in the engine selection process. The pipeline traverses hundreds of miles of terrain that is a study in climatic extremes - from the sweltering humidity of the interior jungle up to the cold, windswept Andean peaks and then down again into the mild climate of the Peruvian coast. The engines had to operate reliably in these harsh conditions on wellhead gas of varying quality.
Providing a constant steady flow through the pipeline was essential for the efficient operation of the processing plant, where storage of the unprocessed liquid was limited. Other requirements for the engines included the ability to operate efficiently in the thin air characteristic of the higher elevations of the mountains.
Waukesha, working through Petroaceras, its distributor in Peru, supplied the engines VGFTM gen-sets that provide electricity for the pumping stations. Waukesha F18GSI units were specified for pumping stations 1, 2 and 3 and an H24GSI was specified for pumping station Number 4. Each unit is rated at 265 kWe.
Waukesha's distributor in Argentina, Servicios Tipsa, specified Waukesha VHPTM L5790GSI units as the pumping engines. The units, rated at 708 - 1215 bhp each, were packaged with Flowserve skid-mounted DMX 12-stage, high-pressure pumps.
The project has been in operation for less than a year, but already production levels have increased to the point that both the pumping engines at each station are needed to handle the load. Four additional L5790 GSI engines have been ordered to provide backup as needed. The operator of the Camisea project is Plus Petrol, an Argentinean company. Another Argentinean firm, Techint, provided engineering services for the entire project.
Waukesha Co-Gen System Makes Brazilian Mall Cool, Bright
Follow Brazil’s Atlantic coastline north from Rio de Janeiro a thousand miles to the sandy beaches of Salvador, capital of Bahia state. Salvador is a vibrant city that boasts colorful 17th and 18th century colonial-era homes, modern high rises, and thriving telecommunications and tourist industries. Visitors come to soak up the sun and experience the area’s unique blend of Brazilian and African infl uences on culture, food, music, dance and folk art.
The city is home to 2.5 million inhabitants and the Iguatemi Mall, one of the largest indoor shopping malls in Brazil, an enormous complex with 540 stores.
Every day 130,000 people – or three million per month – visit the mall. They browse in brightly lit shops and linger over snacks in cool comfort in the food court, thanks to the three Waukesha engine-generator sets that are at the heart of the mall’s co-generation system.
Shoppers aren’t the only ones who benefi t from the mall’s onsite power generation system. Mall tenants, who own their shops in a condominium type arrangement, pay approximately eight percent less for electricity than if they were purchasing it from the local utility.
Air conditioning is a necessity in Salvador, where, it is said, the sun shines almost every day. The climate is tropical and the temperatures are warm year-round with an average low of 70° F (21° C) in winter and an average summertime high of 90° F (32° C). However, in recent years, Brazil’s fast growing economy and tight environmental controls on new power plants have created electrical power shortages, driving up costs and reducing dependability.
As a result, UTC, the corporation that operates of the 30-year old mall, saw the potential for cost-effectively generating its own power onsite by using a co-generation system that would maximize the plant’s energy efficiency. The power plant was commissioned as a build, own, operate and transfer project (BOOT), which required no investment by the mall operators.
Instead, a company called Iguatemi Energia built and owns the plant and sells the power to the mall tenants. At the end of 15 years, ownership of the plant will be transferred to mall operator. According to plant manager Humberto Barra Neto, in that time Energia will have recouped its construction and
start-up costs and turned a profit. The power plant is tucked out of sight down and behind the mall, screened from the street by shrubs and a fence. From the street, the sounds of the plant’s operation are barely audible over noise from traffic.
Location:
Iguatemi Mall, Brazil
Engines:
Three Waukesha 16V-AT27GL Enginator® units
Summary:
A Brazilian shopping mall’s onsite electrical power co-generation system provides a cost-effective alternative to high-priced and less reliable grid power. Three Waukesha natural-gas fired ATGL generator sets provide all the electricity needed for the Iguatemi
Mall and its 540-plus stores, while waste heat from the engines is used in the mall’s air conditioning system.
