Appropriate investigation of acidizing procedures and its significant role in the wellbore production enhancement are utterly dependent on the quality and types of additives, types of acid, acidizing operation and types of formation.
Almost all xylan was removed when reaction severity logR0 > 4.5 and logR0 > 4.2 for water-only and dilute acid operations, respectively.
In line with this reasoning, it is interesting to note that the yields of 5-HMF and furfural observed under water-only and dilute acid operations under analogous severities were comparable.
Predominate soluble sugar fractions and insoluble sugar fractions were converted into sugar monomers at stage 2 for both selected water-only and dilute acid operations, resulting in 52.7 g glucose plus 18.6 g xylose, and 50.8 g glucose plus 18.7 g xylose, respectively.
Regarding acidizing operation, the acid injected rate is approximately 1.2 1.9 bbl./min and the pressure of 3800 6600 psia.
The pretreated biomass solids were biodetoxified in a 15-L bioreactor at 28 °C and aeration for 36 h to remove the inhibitors generated during the dry dilute acid pretreatment operation (Zhang et al. 2010; He et al. 2016).
The practice of dry dilute acid pretreatment operation revealed that well mixing of the majority of lignocellulose solids with minimum steam input in the pretreatment reactor was the major challenge.
The static Young's modulus is also important during the design of the hydraulic and acid fracturing operations for conventional and unconventional reservoirs.
This strategy is successful in substantially retarding the fall-off in plant performance but it does become eventually necessary to conduct an acid-cleaning operation to remove alkaline-scale deposits.
As with CR, acid recovery operations add complexity and capital costs that will be further obstacles to CR implementation.
