Methanol Production in the Brayton Cycle

Abstract

This article presents the concept of renewable methanol production in the gas turbine cycle. As part of the work, an analysis was performed, including the impact of changing the parameters in the methanol reactor on the obtained values of power, yield and efficiency of the reactor, and chemical conversion. The aim of this research was to investigate the possibility of integrating the system for the production of renewable methanol and additional production of electricity in the system. The efficiency of the chemical conversion process and the efficiency of the methanol reactor increases with increasing pressure and decreasing temperature. The highest efficiency values, respectively η = 0.4388 and ηR = 0.3649, are obtained for parameters in the reactor equal to 160 °C and 14 MPa. The amount of heat exchanged in all exchangers reached the highest value for 14 MPa and 160 °C and amounted to Q˙ = 2.28 kW. Additionally, it has been calculated that if an additional exchanger is used before the expander (heating the medium to 560 °C), the expander’s power will cover the compressor’s electricity demand.

Methanol, a Plugin Marine Fuel for Green House Gas Reduction—A Review

“…Methanol, widely recognized as CH 3 OH and commonly denoted as MeOH [64], plays a pivotal role in the chemical and pharmaceutical sectors [65] as well as in the synthesis of artificial hydrocarbons. It is noted that global methanol production has reached approximately 90 million tons per year, with approximately 65% originating from natural gas through steam methane reforming and the remaining 35% derived from coal via gasification procedures [46,66,67].…”

“…Optimal conditions involve a suitable catalyst, low temperatures (<150 • C), and pressures of 5-10 mPa to maximize the CH 3 OH yield and avoid by-product formation. Temperatures above 240 [63], the optimal stoichiometric ratio for maximizing the conversion efficiency in the reaction is M = 2 [46,64].…”
