Investigation of Pipeline Hydrotransport of Agricultural Residue Biomass for Production of Fuels and Chemicals
Authors: Vaezi, M., A. Kumar
Description: Pipeline hydrotransport of agricultural residue biomass to bio-based energy facilities is considered a more economically favorable method than truck delivery, since it is not only benefited from economy of scale, but also helps in reducing the traffic congestion issues. A 25 m closed-circuit pipeline facility is fabricated to experimentally investigate pipeline hydro-transport of knife-milled and pre-classified agricultural residues. After investigating morphological features of agricultural residue biomass, corresponding slurry was prepared and pumped into the closed-circuit pipeline in order to: (1) study the technical feasibility of replacing truck by pipeline in large scale agricultural residue biomass transportations, (2) study friction loss and rheological behavior of agricultural residue biomass slurry through pipeline at various slurry concentrations, slurry flow rates, and agricultural residue biomass particles types and sizes, (3) develop an empirical correlation to predict the agricultural biomass slurry pressure drop across the pipeline , (4) evaluate the performance of centrifugal slurry pumps handling agricultural residue biomass slurry, and finally (5) conduct a series of techno-economic analysis on agricultural residue biomass pipeline hydro-transport. Among all the results obtained, at optimum biomass slurry solid mass content and velocity, the pipeline hydro-transport of biomass was found to be economically more viable than truck delivery at capacities of 0.45 M dry t/yr or more for a one-way pipeline and 1.4 M dry t/yr or more for a two-way pipeline. The results obtained here could potentially enable the large scale bio-based energy facilities to become economically viable.
