Title: Plantwide Energy Assessment of a Sugarcane Farming and Processing Facility

Abstract

A plantwide energy assessment was performed at Hawaiian Commercial & Sugar Co., an integrated sugarcane farming and processing facility on the island of Maui in the State of Hawaii. There were four main tasks performed for the plantwide energy assessment: 1) pump energy assessment in both field and factory operations, 2) steam generation assessment in the power production operations, 3) steam distribution assessment in the sugar manufacturing operation, and 4) electric power distribution assessment of the company system grid. The energy savings identified in each of these tasks were summarized in terms of fuel savings, electricity savings, or opportunity revenue that potentially exists mostly from increased electric power sales to the local electric utility. The results of this investigation revealed eight energy saving projects that can be implemented at HC&S. These eight projects were determined to have potential for $1.5 million in annual fuel savings or 22,337 MWh equivalent annual electricity savings. Most of the savings were derived from pump efficiency improvements and steam efficiency improvements both in generation and distribution. If all the energy saving projects were implemented and the energy savings were realized as less fuel consumed, there would be corresponding reductions in regulated air pollutants and carbonmore » dioxide emissions from supplemental coal fuel. As HC&S is already a significant user of renewable biomass fuel for its operations, the projected reductions in air pollutants and emissions will not be as great compared to using only coal fuel for example. A classification of implementation priority into operations was performed for the identified energy saving projects based on payback period and ease of implementation.« less

  • A safe work environment is needed to support the Savannah River Site (SRS) mission of producing special nuclear material. This Environmental Assessment (EA) assesses the potential environmental impact(s) of adding to and upgrading the Plantwide Fire Protection System and selected related portions of the Domestic Water Supply System at SRS, Aiken, South Carolina. The following objectives are expected to be met by this action: Prevent undue threat to public health and welfare from fire at SRS; prevent undue hazard to employees at SRS from fire; prevent unacceptable delay to vital DOE programs as a result of fire at SRS; keepmore » fire related property damage at SRS to a manageable level;, and provide an upgraded supply of domestic water for the Reactor Areas. The Reactor Areas` domestic water supplies do not meet current demand capacity due to the age and condition of the 30-year old iron piping. In addition, the water quality for these supplies is not consistent with current SCDHEC requirements. Therefore, DOE proposes to upgrade this Domestic Water Supply System to meet current demand and quality levels, as well as the needs of fire protection system improvement.« less
  • Thunder Energy Inc. received approval from the Alberta Energy and Utilities Board for modification of an existing gas plant to process sour gas, and also applied for permission to increase the hydrogen sulfide content of its existing pipelines in the Kelsey area. This report presents the views of Thunder Energy, the Board, and various intervenors at a hearing held to consider objections to the plant approval and matters related to the application. Issues considered include the need for sour gas processing, the need for the plant modification as opposed to the feasibility of using existing sour gas processing facilities, environmentalmore » impacts, and the requirements for notification of industry in the area. The report concludes with the Board`s decision.« less
  • This is the final report of a study undertaken to quantify the cost of production of pipeline quality methane from the anaerobic digestion of California giant brown kelp, macrocystis. Utilizing state-of-the-art knowledge and techniques, kelp would be grown in nearshore farms in 20- to 80-ft-deep ocean waters off the coast of Southern California. It would be harvested, shredded, and pumped as slurry to a central anaerobic biodigestion plant. The kelp would be digested and the resulting gas refined to essentially pure methane. The residue would be a liquid effluent, which would be returned to sea as a nutrient for themore » kelp farm. Detailed capital and operating costs are estimated for several sizes of farm and plant and an economic model is developed that is capable of interacting between various system components so it can be used to test the effect of changes or improvements in individual subsystems on the levelized product cost of the total system.« less
  • This report is the final effort in the Phase I design of a solar industrial process heat system for the Hilo Coast Processing Company (HCPC) in Pepeekeo, Hawaii. The facility is used to wash, grind and extract sugar from the locally grown sugarcane and it operates 24 hours a day, 305 days per year. The major steam requirements in the industrial process are for the prime movers (mill turbines) in the milling process and heat for evaporating water from the extracted juices. Bagasse (the fibrous residue of milled sugarcane) supplied 84% of the fuel requirement for steam generation in 1979,more » while 65,000 barrels of No. 6 industrial fuel oil made up the remaining 16%. These fuels are burned in the power plant complex which produces 825/sup 0/F, 1,250 psi superheated steam to power a turbogenerator set which, in addition to serving the factory, generates from 7 to 16 megawatts of electricity that is exported to the local utility company. Extracted steam from the turbo-generator set supplies the plant's process steam needs. The system consists of 42,420 ft./sup 2/ of parabolic trough, single axis tracking, concentrating solar collectors. The collectors will be oriented in a North-South configuration and will track East-West. A heat transfer fluid (Gulf Synfluid 4cs) will be circulated in a closed loop fashion through the solar collectors and a series of heat exchangers. The inlet and outlet fluid temperatures for the collectors are 370/sup 0/F and 450/sup 0/F respectively. It is estimated that the net useable energy delivered to the industrial process will be 7.2 x 10/sup 9/ Btu's per year. With an HCPC boiler efficiency of 78% and 6.2 x 10/sup 6/ Btu's per barrel of oil, the solar energy system will displace 1489 barrels of oil per year. (WHK)« less
  • The facility design assumptions for a materials recovery facility, a compost facility and an energy from waste facility were intended to result in a facility with minimal impact on the natural environment. The criteria described in discussion paper 3.5A were based on this assumption. This addendum describes the additional criteria identified for use in Step 2 of the site selection process, the revised criteria to be used in Step 3 and the method that will be used to apply the revised Step 3 criterial. Step 2 addresses the type of technology used to minimize adverse effects on the natural environment.more » Step 3 addresses the selection of short-listed sites from a longer list and the methods used.« less
