Abstract: A method for designing capacity of a compressed gas energy storage (CGES) system is provided. Existing design methods determine the rated power and capacity of compressor power, expander power, and volume of the high and low-pressure gas storage tanks, but fail to consider the operation of the power grid, leading to excessively high investment costs and low profits. The design method provided by the present disclosure can effectively avoid this issue. The system factors in local electricity prices, setting constraints to obtain a determined rated capacity and rated power of the CGES system, and the ROI for operating the CGES system. Based on rated capacity rated power, and taking key thermodynamic parameters of each system component as decision variables, a complete capacity and component size of the CGES system can be derived.

Abstract: In certain embodiments the invention is directed to a single layer controlled release pharmaceutical formulation comprising a tablet consisting of a single layer matrix comprising a therapeutically effective amount of alfuzosin or a pharmaceutically acceptable salt thereof dispersed in a controlled release material, wherein the formulation following single dose administration under fed conditions exhibits a mean time to maximum plasma concentration of about 3 hours to about 14 hours.
