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.

Study of Palm Oil Shell Utilization as Metallurgical Coke with Variation of Bondcrete Additive
Jurnal Teknik Kimia dan LingkunganCoke, an essential ingredient in the steel and metallurgical industries, is typically derived from bituminous coal. However, in Indonesia, where bituminous coal is rare, coke production is dependent on coal imports due to the high moisture content of ...

Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking
The Canadian Journal of Chemical Engineering, EarlyView.Abstract In this study, we examine the fluid catalytic cracking (FCC) performance of vacuum gas oil (VGO) from partially upgraded bitumen (PUB), a novel refinery feedstock from Canadian bitumen. FCC experiments were conducted in a lab‐scale FCC unit with VGOs from two different PUBs prepared using thermal cracking and solvent deasphalting, along with ...

Hydrogen donor‐assisted visbreaking of Canadian oil sands bitumen
The Canadian Journal of Chemical Engineering, EarlyView.Abstract High‐viscosity Canadian oil sands bitumen requires processing for efficient transportation and refining. Partial upgrading technologies, primarily based on thermal processing, can effectively reduce, or even eliminate, the use of costly diluent, increase bitumen quality and market value, potentially decrease greenhouse gas (GHG) emissions, and
