Techno‐Economic Analysis of Methanol Production From Steel Mill Gases

Chemie Ingenieur Technik, EarlyView.
A techno‐economic analysis for the synthesis of methanol from steel mill gases is carried out. Four different process concepts are defined and analyzed. The analysis yields levelized cost of methanol estimates between €1130 and €1419 t−1. Sensitivity analyses identify hydrogen production as the largest contributor to cost.

The Influence of Ethical Ideologies on Corporate Social Performance in Small and Medium‐Sized Enterprises in the United Kingdom

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Research addressing the microfoundations of corporate social performance (CSP) in small and medium‐sized enterprises (SMEs) remains sparse. This paper aims to investigate how SME managers' ethical ideology affects CSP and examines the mediating role of their CSR orientation (CSRO): economic, legal, ethical, and philanthropic.

Trim and Engine Power Joint Optimization of a Ship Based on Minimum Energy Consumption over a Whole Voyage

Journal of Marine Science and Engineering
Trim optimization is an available approach for the energy saving and emission reduction of a ship. As a ship sails on the water, the draft and trim undergo constant changes due to the consumption of fuel oil and other consumables.
