Energy Efficiency Methods in the Cement industry – Part 1: Organic Rankine Cycle

See on Scoop.itGreen Energy Technologies & Development

Thomas B. Gibbons takes a look at the Conventional Rankine Cycle’s application in the cement sector

Duane Tilden‘s insight:

>The first major waste heat recovery (WHR) system in a cement plant was the 15 MW unit installed by Kawasaki Heavy Industries for Taiheiyo Cement in 1982. This was a conventional Rankine Cycle using heat from both the kiln and the clinker cooler. As the benefits became generally recognised within the industry, WHR units, the vast majority of which involved the conventional Rankine Cycle, were installed to provide up to about 30% of the power requirements of the plant. The main sources of waste heat were the exhaust from both the preheater and the clinker cooler and, in some of the developing countries where power outages are not unusual, the WHR system may be the only source of reliable power available to the plant operator.

Improvement in the overall efficiency of cement manufacture has resulted in lower exhaust gas temperatures and this development has provided opportunities for alternative technologies, notably the Organic Rankine Cycle (ORC) and the Kalina Cycle, which are more effective in recovering waste heat from lower temperature gases.<

Industrial Energy Management – Contolling Demand & Energy Usage

See on Scoop.itGreen Energy Technologies & Development

Demand-control technology supports multiple approaches for taming energy costs without sacrificing production efficiency.

Duane Tilden‘s insight:

>Navigant Research argues that efficient energy management will soon be as important as product quality in determining manufacturers’ competitive position within their respective industries. That importance, according to Navigant, is reflected in the compound annual growth rate for industrial energy management software and services.

At its current growth rate, the global market for industrial energy management solutions will nearly double over the next 7 years, going from $11.3 billion in 2013 to $22.4 billion in 2020… <

Companies Fined for Greenhouse Gas (GHG) Emissions Reporting Errors | The National Law Review

See on Scoop.itGreen & Sustainable News

Nine companies were issued fines by the California Air Resources Board (ARB) for violating the State of California’s Mandatory Greenhouse Gas Reporting rule. The ARB adopted the reporting rule in 2007.

Duane Tilden‘s insight:

>The companies cited for violations were not concentrated in one industry sector.  Sources receiving fines included a refinery, a biomass generating plant, an oil and gas production company, a utility company, a lime manufacturing company, and a cement company, among others. <

New Report: The Pulp and Paper Industry Can Save Jobs by Becoming More Energy Efficient

“The pulp and paper mill industry may be able to avoid large cuts in jobs by reducing energy costs.”

The complex relationship between efficiency, productivity and employment has been debated at great length by academics and policymakers, who often come to widely differing conclusions about whether jobs will inherently be sacrificed as industry gets more efficient. A prime example is occurring in the U.S. pulp and paper industry, which, over the last decade, has seen productivity and exports grow, even as hundreds of mills closed and 100,000 workers—30 percent of the industry’s workforce—lost their jobs.

But a new report released last week by the environmental think tank World Resources Institute (WRI) proposes that by investing in overhauls that increase energy efficiency, thereby cutting costs on electricity and improving productivity, the country’s paper…

Canada loses WTO appeal in renewable energy case

See on Scoop.itGreen & Sustainable News

BRUSSELS (Reuters) – Canada lost an appeal at the World Trade Organization on Monday in a ruling on incentives offered to local companies, a case that has already led to legal challenges over suspicions…

Duane Tilden‘s insight:

>Ontario will have to bring its rules into line with the WTO rules or risk a claim for trade sanctions against Canada.<

>Canada’s defeat may spur more WTO disputes by countries which are desperate for economic growth and suspect their firms are being illegally locked out of infrastructure projects abroad.<
