Thermodynamic cycles and modern machines

The Carnot Cycle we saw in the first part of this series is idealistic and efficient, but is not easy to use given today’s machinery. All other thermodynamic power cycles use the Carnot cycle as a guide to achieve maximum efficiency. In this second part of the series, the author throws light on the Otto, Diesel and Rankine cycles and their efficiency. The application of these cycles in modern-day machines is also discussed.

South Asia identifies 16,000 MW microhydro power potential

Energy sector professionals from the South Asian countries have estimated a rich potential of approximately 16,000 MW of microhydro power in India, Nepal, Pakistan and Sri Lanka. While India has identified 15,384 MW in small hydro potential, Nepal is looking at an additional 13,000 KW microhydro capacity by 2013. This is attainable with the implementation of certain policies in the construction and operation of microhydro facilities that are capable of achieving additional targets of about 300 MW micro and small hydro power every year.

Rolls-Royce wins Malaysian order

Rolls-Royce has recently won an order for gas turbine and compression equipment for the Tapis oil and gas field, offshore Malaysia. The equipment will be utilized by ExxonMobil Exploration and Production Malaysia (EMEPMI) to expand and extend the production of the field. 

The order includes two Rolls-Royce RB211-GT61 gas turbines, each driving twin Rolls-Royce RCB and RBB multi-stage barrel gas compressors. Each gas turbine compressor set will produce 27MW of power, which can deliver up to 390 million standard cubic feet of natural gas per day.

Wood Group GTS wins gas turbine overhaul contract in Russia

Wood Group GTS has recently been awarded a multi-million dollar contract by MC Systems Energy of Moscow for Surgutneftegas OJSC in Western Siberia, Russia to provide overhaul services for two Siemens SGT-200-1S (Tornado) gas turbines. This contract will enable oil and power production to continue whilst meeting local environmental standards.

Global natural gas consumption

Driven by surging natural gas consumption in Asia and the United States, its global use rebounded 7.4 percent from its 2009 slump to 111.9 trillion cubic feet ­in 2010, according to a new Vital Signs Online report from the Worldwatch Institute. This increase puts natural gas's share of total energy consumption at 23.8 percent.

New Black Hills electric utility

Black Hills Corp. announced recently that its new generation facilities commenced commercial operations from Jan. 1, 2012. Black Hills Energy-Colorado Electric owns the $227 million, 180-megawatt facility, and Black Hills Colorado IPP owns the $260 million, 200-MW facility. The electricity from both facilities is a replacement for a purchase power agreement with Xcel Energy that expired on Dec. 31, 2011. Black Hills Energy will purchase 200 MW of natural-gas-fired generation from Black Hills Colorado IPP under a 20-year agreement.

MHI receives order for 1,600 MW power plant in Thailand

Mitsubishi Heavy Industries (MHI) has recently secured a full-turnkey order from Gulf JP NS Company (GNS) to construct a 1,600MW gas turbine combined-cycle power plant in Thailand. The power plant in Nong Saeng district, Saraburi Province, is being built based on the Thai government's electric power development plan.

Repowering LM2500 plant with in-place upgrade

It took five weeks for GE to perform a major repowering upgrade of its LM2500-PE gas turbine at Cogen España's Tortosa Energía cogeneration plant in Tarragona. As a result of the upgrade, GE's customer now operates a gas turbine offering higher power output, fewer emissions and greater energy efficiency.
