“…The apparatus has extraction and separation vessels of 4 dm 3 and 4 dm 3 in volume, respectively. Maximum working pressure is limited at 500 bar and the extraction temperature can be varied from ambient to 130°C [6]. The sample is loaded into extraction vessel and extracted with supercritical carbon dioxide.…”

Abstract:The goal of this work is isolation of tomato seed oil from the tomato waste (skin and seed) from tomato processing industry by utilization of non-conventional, green solvent technology. In the frames of experimental research, the infl uence of working parameters (temperature, pressure and extraction time) on the total yield of isolated tomato seed oil. Dynamic method for determination of solubility parameter in a supercritical CO 2 has been used to determine the solubility of tomato seed oil in the supercritical CO 2 .Obtained results regarding the infl uence of operating parameters on total yield of extracted tomato seed oil are presented graphically. The infl uence of the supercritical fl uid' density on the tomato seed oil' solubility was determined based on those results. The chemical composition of isolated tomato seed oil was determined by application of Gas Chromatography.

“…with Sh (Sherwood) being the dimensionless number of mass transfer, Sc (Schmidt) the ratio of convective to diffusive mass transfer, Re (Reynolds) the dimensionless number for fluid dynamics, A and n are adapting parameters, varying according the tested material [52]. The maximum validity range for lab scale conditions in high pressure extraction is 3 < Re < 3000, 0.5 < Sc < 10 000 with the adapting parameters 0.1 < A < 2, 0.5 < n < 1.…”

An overview of high pressure processes for producing chemicals from lignocellulosic biomass is presented. Special attention is given to the combination of different process steps and scale-up possibilities for the apparatus involved. Based on literature and own experiments it is shown that, under the condition of an adapted choice of process parameters, high pressure biorefinery allows the connection and combination of different high efficient and selective unit operations to a single one-stop process that can be realized in different scales. Such reactor design can be used for numerous lab scale experiments providing a basis for comparable data for different types of solid biomass. The advantage of such a screening unit is the possibility of cascading processes in the same extraction vessel. Thus, the knowledge on a convergent behavior of reaction and extraction rates can be gained, allowing to progress in modeling of solid biomass conversion under high pressure.

“…The extraction curve as a function of specific amount of the solvent q, can be expressed as e = qy r [1 − exp(−A)] For q < q m (12) where q m = (x 0 − x k )/y r A. As the easily accessible oil gets depleted at the extractor entrance with the specific amount of solvent q m , the transition between CER and FER period occurs.…”
