Disulfide oil (DSO) is produced as a hydrocarbon sulfide waste stream in liquefied petroleum gas and condensate sweetening units in refineries and can cause acute environmental pollutions. In this article, a simple process composed of two units including a distillation unit and a hydrodesulfurization (HDS) unit is proposed to overcome the disulfide oil problem in refineries. The commercial HDS catalyst is CoMo type that is applicable for hydrotreating of DSO. This catalyst is developed by different licensors such as Axens. The high sulfur content in DSO feed causes an increase in heat of reaction and partial pressure of H2S in HDS reactor. By using special design techniques such as reactor quenching or increase H2/oil ratio, the reactor can be designed properly for DSO feed. The waste stream DSO is converted to valuable products including: dimethyl disulfide (DMDS), sweet gas and condensate. A process flow diagram consisting of distillation and HDS units together with amine treating and hydrogen compression system is proposed and simulation of the process is carried out by Aspen plus: The distillation unit separates DMDS and the HDS unit removes sulfur from remainder DSO. Capital cost estimation methodology is based on bare module factor. The capital and operating cost of the process are estimated for a real capacity of DSO just produced in south pars of Iran. Financial parameters and sensitivity analysis show that the process is feasible both technically and economically with an internal rate of return of 73.6%. The proposed process is accepted environmentally by converting a harmful waste to saleable products.

Green Synthetic Fuels: Renewable Routes for the Conversion of Non-Fossil Feedstocks into Gaseous Fuels and Their End Uses

et al. 2020

Innovative renewable routes are potentially able to sustain the transition to a decarbonized energy economy. Green synthetic fuels, including hydrogen and natural gas, are considered viable alternatives to fossil fuels. Indeed, they play a fundamental role in those sectors that are difficult to electrify (e.g., road mobility or high-heat industrial processes), are capable of mitigating problems related to flexibility and instantaneous balance of the electric grid, are suitable for large-size and long-term storage and can be transported through the gas network. This article is an overview of the overall supply chain, including production, transport, storage and end uses. Available fuel conversion technologies use renewable energy for the catalytic conversion of non-fossil feedstocks into hydrogen and syngas. We will show how relevant technologies involve thermochemical, electrochemical and photochemical processes. The syngas quality can be improved by catalytic CO and CO2 methanation reactions for the generation of synthetic natural gas. Finally, the produced gaseous fuels could follow several pathways for transport and lead to different final uses. Therefore, storage alternatives and gas interchangeability requirements for the safe injection of green fuels in the natural gas network and fuel cells are outlined. Nevertheless, the effects of gas quality on combustion emissions and safety are considered.

Purpose. To investigate the main basic physical and chemical properties of coalbed methane (CBM), conditions of its formation and places of occurrence. Special attention is paid to CBM utilization using alternative methods such as gas hydrate technologies and nanotechnologies.Methods. Analysis of geological conditions of CBM occurrence and its content in several countries and methods of increasing gas hydrate formation rate to intensify gas utilization.Findings. The reserves of CBM in different countries are classified according to the amount of gas in each country. A wide review is given to the methods of gas hydrates formation rate intensification and nanotechnologies application using different chemical compounds to utilize and transport CBM by ground transportation. Originality. Gas hydrates and dry water have been proposed as alternative methods of CBM utilization and transportation in a solid form. Practical implications.Colossal amounts of methane released into the atmosphere from underground coal mines can be captured and converted into a solid or powder form for transportation over large distances under moderate thermobaric conditions.
