Energy conservation in citrus processing. Technical progress report, October 1, 1979-March 31, 1980

The Sunkist Citrus Plant in Ontario, California, processes about 6 million pounds of citrus fruit per day to make products which include frozen concentrated juice; chilled, pasteurized, natural strength juice; molasses from peel; dried meal from peel; pectin; citrus oil; and bioflavonoids. The energy intensive operations at the plant include concentration, drying, and refrigeration. The objective of the two-year two-phase project is to identify an economically viable alternative to the existing method of meeting energy requirements. Progress on the technical work of Phase I is reported. The following are summarized: requirements (energy price projection, atmospheric emission requirements, citrus juice quality constraints, economic evaluations); characterization (basic citrus processing operations, energy consumption and fruit processed vs time, identification and measurement of energy uses, energy balance for a typical citrus juice evaporator); and thermodynamic analysis (heat pump model, thermal evaporator, and co-generation model).

Leave Benefits in the United States

This report begins by reviewing the federal statutes that pertain directly or indirectly to employer provision of leave benefits for any purpose, including a discussion of the California and New Jersey family leave insurance programs. The report than examines the incidence of different types of paid leave that U.S. employers voluntarily provide as part of an employee's total compensation (wages and benefits). The report closes with results from a federal government survey of the average direct cost to business of different types of leave.

Assessment of advanced coal-gasification processes. [AVCO high throughput gasification in process; Bell High Mass Flux process; CS-R process; and Exxon Gasification process] (open access)

Assessment of advanced coal-gasification processes. [AVCO high throughput gasification in process; Bell High Mass Flux process; CS-R process; and Exxon Gasification process]

This report represents a technical assessment of the following advanced coal gasification processes: AVCO High Throughput Gasification (HTG) Process, Bell Single - Stage High Mass Flux (HMF) Process, Cities Service/Rockwell (CS/R) Hydrogasification Process, and the Exxon Catalytic Coal Gasification (CCG) Process. Each process is evaluated for its potential to produce SNG from a bituminous coal. In addition to identifying the new technology these processes represent, key similarities/differences, strengths/weaknesses, and potential improvements to each process are identified. The AVCO HTG and the Bell HMF gasifiers share similarities with respect to: short residence time (SRT), high throughput rate, slagging and syngas as the initial raw product gas. The CS/R Hydrogasifier is also SRT but is non-slagging and produces a raw gas high in methane content. The Exxon CCG gasifier is a long residence time, catalytic fluidbed reactor producing all of the raw product methane in the gasifier.

Cost of energy from utility-owned solar electric systems. A required revenue method for ERDA/EPRI evaluations (open access)

Cost of energy from utility-owned solar electric systems. A required revenue method for ERDA/EPRI evaluations

This methodology calculates the electric energy busbar cost from a utility-owned solar electric system. This approach is applicable to both publicly- and privately-owned utilities. Busbar cost represents the minimum price per unit of energy consistent with producing system-resultant revenues equal to the sum of system-resultant costs. This equality is expressed in present value terms, where the discount rate used reflects the rate of return required on invested capital. Major input variables describe the output capabilities and capital cost of the energy system, the cash flows required for system operation and maintenance, and the financial structure and tax environment of the utility.

OSHA State Plans: In Brief, with Examples from California and Arizona

This report examines various state plans under the Occupational Safety and Health Act of 1970 (OSH Act), which authorizes states to establish their own occupational safety and health plans and preempt standards established and enforced by the Occupational Safety and Health Administration (OSHA). OSHA must approve state plans if they are "at least as effective" as OSHA's standards and enforcement. The report provides specific examples from California and Arizona

Mission Bay Harbor, California, Design for Wave and Surge Protection and Flood Control: Hydraulic Model Investigation

Partial abstract: A 1:100-scale (undistorted) hydraulic model, reproducing Mission Bay Harbor, approximately 3 miles of shoreline, and sufficient offshore area to permit generation of the required test waves, was used to investigate the arrangement and design of proposed structures for (a) improving hazardous entrance conditions, (b) reducing surge inside the harbor, and (c) eliminating potential flood hazards. The original proposal for harbor improvement consisted of a 2,200-ft-long offshore breakwater. The proposed structures for river flood control consisted of (a) a 1,200-ft-long weir in the middle jetty, (b) various south jetty extensions, and (c) diversion dikes on the middle jetty.

Geologic Summary of the Central Valley of California with Reference to the Disposal of Radioactive Waste

From introduction: This report describes the geology of the area only to the extent necessary for preliminary evaluation of the possibilities for the disposal of liquid radioactive waste by injection through deep wells. Their value will increase with development of extensive commercial production of atomic power and attendant creation of radioactive waste from the processing of spent fuel elements. The disposal of liquid waste in deep reservoirs is only one of several possibilities that must be considered.

Artificial Recharge in the Northern Part of Chino Ground-Water Basin, Upper Santa Ana Valley, California

Purpose and Scope: The purpose of this study was to evaluate the geohydrologic characteristics that influence sustained artificial recharge and to determine long-term infiltration rates in the northern part of Chino ground-water basin. Results of this study will help management to design and implement a recharge-recapture system in Chino Basin. Nine test holes were drilled, long-term infiltration tests were made, and drillers' logs and water-level data were evaluated to determine the probable effects of recharging the ground-water basin. The study was concentrated in the northern part of Chino Basin, where recharge is proposed.

Report on Applicability of Residential Ventilation Standards in California (open access)

Report on Applicability of Residential Ventilation Standards in California

The California Energy Commission is considering updating its requirements for residential ventilation in the next round of its energy code, known as ''Title 24''. This report contains recommendations for potential changes to the code. These recommendations must be further developed into specific wording before they can be formally considered. Residential ventilation standards always address local and whole-house ventilation rates and some basic source control requirements, but there are many interactions with building systems that must also be considered. McKone and Sherman [8] laid out a set of additional issues that should be addressed before any specific changes to the code should be made. Those key issues included the following: Adventitious Air Flow; Air Distribution; Filtration and Air Cleaning; Occupant Acceptability and Control; Outdoor Air; Peak Demand; Unusual Sources and High-Polluting Events; and Window Operation. McWilliams and Sherman reviewed the literature on residential ventilation and in particular these key issues. They also reviewed codes, standards and guidelines relevant to residential ventilation. That literature serves as the technical basis for this report.
