| Bitumen Froth Cleaning Using Hydrothermal Treatment Plus Hot FiltrationPresenting the latest results of hydrothermal treatment + hot filtration process for bitumen froth cleaning using a semi-large scale autoclave.
The results showed that this process can effectively reduce the water and sand contents without using any chemical solvents plus performing a semi-updating on the bitumen. The project successfully reduced the water content from 19 wt% to 0.03 wt%, similarly the fine sand from 6 wt% to 0.5 wt% by hot filtration at 200 of using a 0.5 lm pore size stainless steel filter medium.
The future plan is to reduce the fine solids contents in the final bitumen product down to 0.05 wt% by using double/triple reused filtration. During each filtration, the filter cake will increase and it can remove more fine solids.

| Bitumen Froth Cleaning Using Hydrothermal Treatment Plus Hot FiltrationBitumen froth produced in mineral extraction contains about 60% bitumen, 30% water and 10% fine solids. This product requires further cleaning before the bitumen can be upgraded to crude oil or sold to market. Two technologies are currently used for cleaning bitumen froth, depending on the solvent used to dilute the bitumen froth and lower its viscosity. Both the froth cleaning processes require distillation to remove the large volumes of solvent from the bitumen product, and solvent recovery units to recover the residual solvents from the fine solids and water. Inefficiencies in solvent recovery are a major contribution to solvent losses into the tailings ponds.
Hence, any technology which can alter the surface properties of the fine solids may be a potential choice for froth cleaning. Hydrothermal treatment is direct thermal processing of bitumen froth at elevated temperature (up to 450 C) rather than the current approach of froth treatment followed by upgrading. Filtration at high temperature offers many advantages, such as increased overall efficiency, improved product quality, recovery of thermal energy, and integration of filtration into the overall process.
Thus, we purposed, a combination of hydrothermal treatment, venting and filtration to clean the bitumen froth. The results show that hydrothermal treatment followed by venting and filtration is an effective way to remove water and fine solids from bitumen froth: the water content was reduced from 19 wt% to 0.05 wt%, and the fine solids content was reduced from 6 wt% to 0.5 wt% by hot filtration at 200 C using a 0.5 lm pore size stainless steel filter medium.

| In-Situ Hot Filtration of Bitumen Streams to Produce Dry and Solids-Free Bitumen ProductIn this study, a combination of hydrothermal treatment, venting and filtration was investigated to clean the bitumen froth. Laboratory hydrothermal treatment was conducted at 300–420 C for 0–180 min. The filterability of fine solids was quantitatively characterized by room-temperature filtration or hot filtration at 200 C.
The results show that hydrothermal treatment followed by venting and filtration is an effective way to remove water and fine solids from bitumen froth. The results showed that the water content was reduced from 19 wt% to 0.05 wt%, and the fine solids content was reduced from 6 wt% to 0.5 wt% by hot filtration at 200 C using a 0.5 lm pore size stainless steel filter medium.

| Innovative Process for Bitumen Froth Cleaning Using Hydrothermal Treatment Plus Hot FiltrationBitumen froth produced in mineral extraction contains about 60% bitumen, 30% water and 10% fine solids. This product requires further cleaning before the bitumen can be upgraded to crude oil or sold to market. Two technologies are currently used for cleaning bitumen froth, depending on the solvent used to dilute the bitumen froth and lower its viscosity. When naphtha distillate is used (naphthenic froth treatment (NFT)), the emulsion is only partly broken and significant amounts of solids and water remain even after using inclined-plate settlers and centrifuges. In this case, the resulting bitumen can still contain 2–5 wt% water and 0.5–1 wt% fine solids and cannot be transported by pipelines unless it is first processed by coking type upgrading plants.
When a poor solvent such as hexane is used (paraffinic froth treatment (PFT)), 4–10% of the bitumen fraction, mostly asphaltene, precipitates, flocculating and removing with it almost all water and fine solids. Both the froth cleaning processes require distillation to remove the large volumes of solvent from the bitumen product, and solvent recovery units to recover the residual solvents from the fine solids and water. Inefficiencies in solvent recovery are a major contribution to solvent losses into the tailings ponds.
Alternative technologies for froth cleaning are desirable if they can reduce the equipment cost, reduce energy consumption, and reduce environmental impact. The bi-wettable fine solids stabilize water-in-oil emulsions, which, in turn, makes solids and water removal from bitumen froth extremely difficult. Hence, any technology which can alter the surface properties of the fine solids may be a potential choice for froth cleaning. Hydrothermal treatment is direct thermal processing of bitumen froth at elevated temperature (up to 450 C) rather than the current approach of froth treatment followed by upgrading. After the hydrothermal treatment, the wide range of the surface properties of the initial fine solids particles with a high disparity of wettability was made uniformly hydrophobic. Filtration is a well-established method for solid-liquid separation. Although bitumen is viscous at room temperature, at the elevated temperatures that follow hydrothermal treatment its lowered viscosity may enable filtration. Filtration at high temperature offers many advantages, such as increased overall efficiency, improved product quality, recovery of thermal energy, and integration of filtration into the overall process.
Thus, we purposed, a combination of hydrothermal treatment, venting and filtration to clean the bitumen froth. Laboratory hydrothermal treatment was conducted at 300–420 C for 0–180 min at semi-large scale autoclave (5.5 Liter). The filterability of fine solids was quantitatively characterized by room-temperature filtration or hot filtration at 200 C. The results show that hydrothermal treatment followed by venting and filtration is an effective way to remove water and fine solids from bitumen froth: the water content was reduced from 19 wt% to 0.05 wt%, and the fine solids content was reduced from 6 wt% to 0.5 wt% by hot filtration at 200 C using a 0.5 lm pore size stainless steel filter medium.
The future plans are to optimize the temperature condition while reduce the fine solid content down to 0.03 wt% by using double/triple reused filtration. University of Alberta | Activity | 2020-01-22 | Qiang Chen, Shahrad Booran, Tan, X., "Igor Stricek", Liu, Q. |

| Thermal Treatment of Bitumen Froth at a Temperature of 250 °C and the Role of Clay Minerals in this ProcessBitumen is recovered from mined oil sands using a hot water extraction process, the product of which is called bitumen froth. Bitumen froth is a mixture of about 60 wt% bitumen, 30 wt % water and 10 wt% mineral solids. The bitumen in bitumen froth needs to be separated from the water and solids to convert it into a marketable bitumen product. To achieve this, solvent-based froth treatment processes are employed in the industry, which are operated at temperatures in the range 30-85 °C. An alternate approach, called hydrothermal treatment, which involves direct heating of bitumen froth without solvent addition was investigated in this work. Two studies were conducted, one to empirically evaluate the potential benefit of hydrothermal froth treatment, and one to investigate the role of mineral matter in the conversion process. Results indicated that hydrothermal froth treatment at 250 °C did not lead to the upgrading of the bitumen, and that thermal conversion of bitumen at the study conditions was beneficial only when the bitumen was treated on its own. Viscosity was one of the characteristic properties of bitumen measured in this work, and it was found that the presence of water and/or mineral solids during thermal conversion led to an increase in the viscosity of bitumen. These viscosity changes were accompanied by an increase in the free radical concentration in bitumen. It was hypothesized that the minerals, especially clays, might be responsible for promoting heavier material formation through free radical and/or cationic addition reactions. To test this hypothesis, the conversion of probe molecules α-methylstyrene (AMS) and 1-octene, instead of bitumen froth, at 250 °C was studied in the presence of the clay minerals kaolinite and illite, which are predominantly found in bitumen froth. While pure thermal conversion of AMS and 1-octene in the absence of minerals was noticed to be low, the conversion increased in the presence of the clay minerals. The minerals promoted heavier product formation through dimerization of AMS and alkylation of 1-octene and toluene (used as solvent), which were identified as the major reactions. The clay minerals also promoted formation of cumene from AMS and double bond isomerization of 1-octene, which were the side reactions. Additional reactions conducted in the presence of clay minerals and pyridine were used as surrogates for alkaline bitumen froth and to differentiate between free radical and cationic pathways. It was concluded that minerals could promote heavier material formation even under alkaline conditions, and that the mineral related conversion was primarily cationic in nature (Figure 1).

| Free Radical and Cationic Addition due to Clay Minerals Found in Bitumen Froth at 250 °C Probed with Use of α-Methylstyrene and 1-OcteneFollowing previous evidence that hydrothermal treatment of bitumen froth does not lead to bitumen upgrading at 250 °C and promotes viscosity increase, the current study explores the free radical and cationic reactivity of clay minerals found in bitumen froth in promoting heavier material formation through addition reactions. The current investigation employed α-methylstyrene (AMS) and 1-octene as probe molecules instead of bitumen froth, and their conversion at 250 °C in the presence of clay minerals kaolinite and illite was studied in batch reactors. Thermal conversion of AMS and 1-octene at 250 °C in the absence of minerals was observed to be low. In the presence of clay minerals, not only the conversion of AMS and 1-octene was increased but also reactions such as dimerization of AMS and alkylation of 1-octene and toluene (used as solvents) were mainly promoted, leading to heavier product formation. Double-bond isomerization of 1-octene and cumene formation from AMS was side reactions that were also promoted by the clay minerals. Suppression of mineral-related conversion by pyridine and selectivity to different reaction products that enabled differentiation between free radical and cationic reaction pathways indicated that the mineral-related conversion was predominantly cationic in nature. Using the reactions in the presence of minerals and pyridine as surrogates for alkaline bitumen froth, it was concluded that even under alkaline conditions, minerals could promote heavier material formation through cationic addition.

| Hydrothermal Treatment of Bitumen Froth: Impact of Mineral Solids and Water on Bitumen PropertiesHydrothermal treatment, i.e., thermal treatment of bitumen in the presence of water and solids, as a potential approach for combined froth treatment and upgrading was investigated in this work. Reactions were performed in batch reactors at 250 °C with the bitumen, water, and solid phases separated from industrially obtained bitumen froth, and the impact of the presence or absence of water
and/or solids on the bitumen conversion was studied. Statistical analysis of bitumen properties revealed that the hydrothermal treatment of the bitumen froth at 250 °C did not lead to upgrading of the bitumen. Treatment at the conditions used in this study was beneficial only when the bitumen was converted on its own. Water and/or mineral solids contributed to an increase in viscosity, which
was accompanied by an increase in free radical content. These observations were tentatively explained based on the generation of free radicals by redox reactions and heavier product formation promoted by free radical addition reactions. While the treatment did not significantly impact the density of bitumen, changes in the H/C ratio, n-heptane insoluble content, and metal content of bitumen were noted. The total acid number (TAN) of bitumen increased in the presence of water and mineral solids. Base catalyzed hydrolysis of esters and anhydrides in bitumen might be responsible for the increase in TAN, and the solids and water appeared to promote these reactions.
