Development and demonstration of the use of modular thermo-mechanical pulpmill simulation models to develop energy reduction strategies

The Institute of Paper Science and Technology (IPST) has received a project grant from the US DOE to develop and demonstrate the use of realtime process simulation modeling as a means of process analysis and optimization. The Project, to be conducted under the auspices of the International Energy Agency (IEA), will target a Thermo-Mechanical Pulping (TMP) operation as the site for the commercial implementation of the technology. IPST and a sub-contractor, SACDA Inc. (SACDA), will cooperate in a two-to-three year effort to produce an on-line simulation program having both steady-state and dynamic modeling capabilities. The Project will take advantage of a current IPST and SACDA joint development effort to merge the IPST's MAPPS (Modular Analysis of Pulp and Paper Systems) program with SACD's MASSBAL program. Using the combined proprietary programs, realtime'' steady-state and dynamic TMP models will be developed and installed as part of a millwide'' information/analysis system. By utilizing the Performance Attribute (PAT) Modeling concept developed at IPST, the models will have the capability of optimizing energy usage and other process operating variables as a function of pulp quality. The primary goal of the Project is to demonstrate that on-line simulation models can provide assistance to operators and managers …

Innovative clean coal technology (ICCT): Demonstration of innovative applications of technology for cost reductions to the CT-121 FGD process (open access)

Innovative clean coal technology (ICCT): Demonstration of innovative applications of technology for cost reductions to the CT-121 FGD process

The objective of this project is to demonstrate on a commercial scale several innovative applications of cost-reducing technology to the Chiyoda Thoroughbred-121 (CT-121) process. In both greenfield and retrofit situations demonstrations of the following innovative design approaches will further reduce the cost and provide a clear advantage to CT-121 relative to competing technologies. Use of fiberglass reinforced plastic (FRP) to construct the absorber vessel, wet ducts, and chimney (stack), elimination of flue gas reheat, elimination of the spare absorber, and use of a single vessel for simultaneous particulate and SO{sub 2} removal. The demonstration will be performed at Georgia Power Company's Plant Yates Unit No. 1 (100 MW capacity) near Newman, Georgia. The project is being conducted in the following three phases: Phase 1 -- Permitting and Preliminary Engineering; Phase 2 -- Detailed Engineering, Construction, and Startup; and Phase 3 -- Operation, Testing and Disposition. Since April, all environmental permits and FAA approvals have been granted by the issuing authorities with the exception of the gypsum stack design and operating plan permit which is expected within the next 60 days. Phase 2 activities reached a peak during the April--June quarter as major components were fabricated and delivered to the site. …

Strategic Petroleum Reserve quarterly report (open access)

Strategic Petroleum Reserve quarterly report

This August 15, 1991, Strategic Petroleum Reserve Quarterly Report describes activities related to the site development, oil acquisition, budget and cost of the Reserve during the period April 1, 1991, through June 30, 1991. The Strategic Petroleum Reserve storage facilities development program is proceeding on schedule. The Reserve's capacity is currently 726 million barrels. A total of 5.5 million barrels of new gross cavern volume was developed at Big Hill and Bayou Choctaw during the quarter. There were no crude oil deliveries to the Strategic Petroleum Reserve during the calendar quarter ending June 30, 1991. Acquisition of crude oil for the Reserve has been suspended since August 2, 1990, following the invasion of Kuwait by Iraq. As of June 30, 1991, the Strategic Petroleum Reserve inventory was 568.5 million barrels. The reorganization of the Office of the Strategic Petroleum Reserve became effective June 28, 1991. Under the new organization, the Strategic Petroleum Reserve Project Management Office in Louisiana will report to the Strategic Petroleum Reserve Program Office in Washington rather than the Oak Ridge Field Office in Tennessee. 2 tabs.
