Refining crude oil - inputs and outputs - U.S. Energy

Refining output is larger than input. The total volume of products refineries produce (output) is greater than the volume of crude oil that refineries process (input) because most of the products they make have a lower density than the crude oil they process. This increase in volume is called processing gain. The average processing gain at U.S ...

Emissions from the Cement Industry

May 09, 2012 · Its production is growing by 2.5 percent annually, and is expected to rise from 2.55 billion tons in 2006 to 3.7-4.4 billion tons by 2050. Manufacture of Cement. Though “cement” and “concrete” are often used interchangeably, concrete is actually the final product made from cement. The primary component of cement is limestone.

Managing Productivity | Boundless Management

At the plant level, common input statistics are monetary units, weights or volumes of raw or semi-finished materials, kilowatt hours of power, and worker hours. Output is simply the rate of which goods are being produced and readied for sale. Managing production levels is part of the control process.

Midlothian residents deserve input on health, cement plant

Cement production near Dallas-Fort Worth is vital to the U.S. economy, but regulators should fully hear concerns about air quality and the environment and consider new air monitors.


process in cement plant was carried out using input-output data collected from one of the ce- ment plants in Nigeria. Neurofuzzy system which is based on the adaptive network-based fuzzy in-ference system (ANFIS) was employed in an at-tempt to predict dynamic blending process in ce-ment plant. The input is clay feed rate and output is the total carbonate content of the raw mix. The flow of ...

Characteristics of mercury cycling in the cement

2016-01-25 · The proportions of mercury input from flue gas emitted from the kiln tail reached 83.7% and 68.5%, much higher than that of the raw materials, which were 12.5% and 30.4% in Plants 1 and 2, respectively. The main reason for this difference was the high concentration of mercury in the flue gas caused by mercury enrichment.
