“…The used data related to the characteristics of the feed stream to be flowed into the MR were obtained by a simulation of the aforementioned refinery (the same software as reported in [6] was used). Then, the composition and conditions of feed the stream before entering in the MR are shown in Tables 5 and 6.…”

“…Every day, about 1400 million standard cubic feet (MMscf) of gas are fed to this plant. In a recent work, a simulation study was performed by using the steady state process simulation software (licensed by the Oil Company, Iran) with a hardware lock of S/N 08225, demonstrating that, in this refinery, more than 4.0 MMscf/d of gas are flared in three units ("100", "300", "600") [6]. The composition and conditions of gathered flare gas are resumed in Tables 1 and 2.…”

A rise in CO2 and other greenhouse gases’ concentration from gas refinery flares and furnaces in the atmosphere causes environmental problems. In this work, a new process was designed to use waste gas (flue gas and flare gas) of a domestic gas refinery to produce pure hydrogen in a membrane reactor. In particular, the process foresees that the energy and CO2 content of flue gas can provide the heat of the mixed reforming reaction to convert flare gas into hydrogen. Furthermore, the characteristics of the feed stream were obtained via simulation. Then, an experimental setup was built up to investigate the performance of a membrane reactor allocating an unsupported dense Pd-Ag membrane at the mentioned conditions. In this regard, a Ni/CeO2 catalyst was loaded in the membrane reformer for mixed reforming reaction, operating at 450 °C, in a pressure range between 100 and 350 kPa and a gas hourly space velocity of around 1000 h−1. The experimental results in terms of methane conversion, hydrogen recovery and yield, as well as products’ compositions are reported. The best results of this work were observed at 350 kPa, where the MR was able to achieve about 64%, 52% and 50% for methane conversion, hydrogen yield and recovery, respectively. Furthermore, with the assistance of the experimental tests, the proposed process was simulated in the scaling up to calculate the needed surface area for MR in the domestic gas refinery.

“…Interactions A × B, A 2 , and B 2 have a statistically significant effect on the amount of liquid produced in CPOX and SMR, and the interaction C 2 has a significant effect for the ATR process. From the effects of main factors and their interactions for all the responses under study, we created the polynomial models with statistical significance generated by a combination of estimates for the process variables and ANOVA results ( Table 9; Equations (14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)). …”

“…Economies of scale are a major impediment to commercializing micro-refinery technology. [15] Moreover, micro-refinery unit (MRU) fuel yields are as much as 80 % of the large-scale processes. [16] Commercial units have the advantage of higher yields and investment costs are as low as 100 k$ · bbl −1 , which translates to a cost of $1 000 000 for a 1600 L · d −1 (10 bbl · d −1 ) MRU assuming a linear scale-up factor on investment.…”

Micro‐syngas technology options for GtL

Natural gas emissions contribute to climate change, and equally importantly, affect the health of populations near gas fields.[1] At night, the flares from the Bakken fields in North Dakota burn as bright as the lights in cities as large as Minneapolis. Rather than flaring (or worse, venting), this associated natural gas represents a multi‐billion dollar opportunity.[2] Pipelines and liquefying natural gas are cost prohibitive in many cases. Converting methane to fuels is an attractive alternative. We examined three options to convert natural gas to syngas (H2 and CO), which is the first step to producing fuels: Steam Methane Reforming (SMR), Auto‐Thermal Reforming (ATR), and Catalytic Partial Oxidation (CPOX). Based on a multi‐objective optimization analysis, C5+ hydrocarbon yields are highest with CPOX as the first step followed by Fischer‐Tropsch synthesis (FT). A micro‐refinery with the CPOX‐FT process treating 2800 normalkL·d−1 (100 MCF·d−1) natural gas, produces 1300 normalL·d−1 (8.2 bbl·d−1) of C5+ hydrocarbons. Maximum yields for the SMR‐FT and ATR‐FT processes are 938 normalL·d−1 and 1100 normalL·d−1 (5.9 bbl·d−1, 7.0 bbl·d−1) of C5+, respectively. Large‐scale POX and ATR processes produce 1600 L per 2800 kL (10 bbl per 100 MCF) of natural gas.

Flaring is a common industrial practice that leads to substantial greenhouse gas (GHG) emissions, health problems, and economic losses. When the causes, magnitudes, and frequency of flaring are properly understood and incorporated into the design and operation of the industrial plants, significant reduction in flaring can be achieved. In this paper, a process integration approach is presented to retrofit the process design to account for flaring and to consider the use of process cogeneration to mitigate flaring while gaining economic and environmental benefits. It is based on simultaneous design v
