The Lang Factor is an estimated ratio of the total cost of creating a process within a plant, to the cost of all major technical components. It is widely used in industrial engineering to calculate the capital and operating costs of a plant.. The factors were introduced by H. J. Lang and Dr Micheal in Chemical Engineering magazine in 1947 as a method for estimating the total installation ...

CheCalc. Chemical engineering calculations to assist process, plant operation and maintenance engineers.
Factor Estimating. In the first phases, you can make use of several factor estimating techniques that allow for an estimate with limited accuracy but enough confidence for a go / no go decision. The factor estimating method derives its name from applying derivative factors for the preparation of the investment estimate of a project.
Feb 18, 2017· The below tabulation shows typical indicative engineering costs for various projects with varying CAPEX values. Engineering Cost Thumb Rules (Excel Version) – free estimating resource. These rough percentages are very much high level indicative numbers, based on experience, to just help with a quick calculation of the total engineering costs.

Abstract. As indicated in Chapter 1, one of the basic economic skills that chemical engineers often need is the ability to make cost estimates. The foundation of most estimates is the cost of individual pieces of equipment, and developing that estimating skill is the purpose of this chapter.
May 11, 2015· Cost Estimation in Chemical Engineering. By: Sean Moran, The Voice of Chemical Engineering, Posted on: May 11, 2015. Nothing is less well taught in academic “Chemical Engineering” than costing. That the scientists and mathematicians who staff Chemical Engineering departments are more interested in science and maths than the whole point of ...
Correlations for constants can be found in Towler's Chemical Engineering Design (Towler and Sinnott, 2013). Example: Estimate the cost of a 30 m^2 double pipe heat exchanger. C_e = 1900 + 2500*S^1.0 for S = [1 m^2, 80 m^2] C_e = $76900 Estimation based on component cost
May 10, 2014· ESTIMATION OF PURCHASED EQUIPMENT COSTS The cost of the purchased equipment is used as the basis of the factorial method of cost estimation and must be determined as accurately as possible. It should preferably be based on recent prices paid for similar equipment. The relationship between size and cost given in equation 6.2 can also…
Cost engineering is "the engineering practice devoted to the management of project cost, involving such activities as estimating, cost control, cost forecasting, investment appraisal and risk analysis." "Cost Engineers budget, plan and monitor investment projects. They seek the optimum balance between cost, quality and time requirements."
