Book Description

This report presents a cost analysis of Cumene production from benzene and refinery grade (RG) propylene. The process examined is a typical alkylation process using a zeolite catalyst. This report was developed based essentially on the following reference(s): Keywords: Propene, UOP Qmax, CB&I Lummus, CDTECH, CDCumene, Mobil/Badger, Zeolite




Cumene Production Process - Cost Analysis - Cumene E15A


Book Description

This report presents a cost analysis of Cumene production from benzene and refinery grade (RG) propylene. The process examined is a typical alkylation process using a zeolite catalyst. This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses: * Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up * Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs * Raw materials consumption, products generation and labor requirements * Process block flow diagram and description of industrial site installations (production unit and infrastructure) Keywords: Propene, UOP Qmax, CB&I Lummus, CDTECH, CDCumene, Mobil/Badger, Zeolite

Description of Russian Aircraft Engines "AM 35" and "AM 38"


Book Description

The Russian AM 35 and AM 38 aircraft engines have superchargers with a swirl throttle, which appears to be a purely Russian development. This paper gives the results of test runs of the two engines, including the effects of the swirl throttle on engine performance.




Dynamic Stability of Vehicles Traversing Ascending Or Descending Paths Through the Atmosphere


Book Description

An analysis is given of the oscillatory motions of vehicles which traverse ascending and descending paths through the atmosphere at high speed. The specific case of a skip path is examined in detail, and this leads to a form of solution for the oscillatory motion which should recur over any trajectory. The distinguishing feature of this form is the appearance of the Bessel rather than the trigonometric function as the characteristic mode of oscillation.




Analytical Investigation of Some Three-dimensional Flow Problems in Turbomachines


Book Description

The flow of an incompressible inviscid fluid through a turbomachine with blade rows consisting of an infinite number of similar infinitely thin blades has been investigated theoretically in order to examine and describe the three-dimensional flow phenomena and to illustrate the methods of calculation developed.




Method of Matching Components and Predicting Performance of a Turbine-propeller Engine


Book Description

Analytical expressions are derived to show the geometric, thermodynamic, and aerodynamic relations among compressor, turbine, and exhaust nozzle for a gas-turbine engine. For a known compressor performance map, a matching method is described to show some of the design compromises that must be made when the components are to be combined into a turbine-propeller engine. A method of predicting engine performance for a range of operating conditions from known component maps is presented. An illustrative example of the matching method and the performance analysis is presented, showing some of the practical limitations of engine operation.




Analysis of the Effects of Design Pressure Ratio Per Stage and Off-design Efficiency on the Operating Range of Multistage Axial-flow Compressors


Book Description

Multistage compressors composed of high-pressure-ratio stages have higher over-all off-design efficiencies and a wider operating range than those made up of low-pressure-ratio stages if the blade-row efficiency curves for the two cases are assumed to be somewhat similar.
