The Cost of Carbon Capture - CCST @ MIT

The second three inputs characterize the capture plant: • Incremental capital cost, in $/kg of CO 2 processed per hour; • Incremental cost of electricity due to operation and maintenance, in mills/kg of CO 2 processed; • Energy requirements of the capture process, in kWh/kg of CO 2 processed. The capture efficiency is usually about 90% in the studies reviewed.

Rice Husk Ash - an overview | ScienceDirect Topics

A rice mill turns the paddy plant into 78% rice, 20% rice husk and 2% is lost in the process (Ash, 2010). The rice husk contains about 50% cellulose, 25–30% lignin and 15–20% silica (Ismail & Waliuddin, 1996). Hence, after the combustion, one-fifth to one-quarter of the rice husk will change into ash.
