  • Lang Factor Cost Estimating prjmgrcap

    The method presented by Mr. Lang was based on a study of fourteen (14) plant estimates of various sizes and types, ranging from $100,000 to $15,000,000 (late 1940's USD). He identified three process plant types, solid processing plants, solid-fluid processing plants, and fluid processing plants.

    Re-Processing Gold Tailings in South Africa

    historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid mine drainage. The tailings from the re-processing plant will be re-

  • [] A method for estimating the capital cost of chemical

    The purpose of this thesis is to improve the 'art' of early capital cost estimation of chemical process plants. Capital cost estimates are required in the early business planning and feasibility assessment stages of a project, in order to evaluate viability and to compare the economics of the alternative processes and operating conditions that are under consideration for the plant.

    Capital Cost Estimates for Utility Scale Electricity

    Estimates of the overnight capital cost, fixed and variable operations and maintenance costs, and plant heat rates for generic generating technologies serve as a starting point for developing the total cost of new generating capacity. However, other parameters also play a key role in determining the total capital costs.
