Early life and education

Dr. Agrawal received a B.Tech. in chemical engineering from the Indian Institute of Technology in Kanpur, India, in 1975; a M. Ch.E. from the University of Delaware in Dover, Delaware in 1977, and an Sc.D. in chemical engineering from the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts in 1980. [2]

Career

In 1980, Rakesh Agrawal joined Air Products in Trexlertown, Pennsylvania, where he was appointed to Air Products Fellow. [3]

In 2002, Agrawal was elected as a member of the National Academy of Engineering for contributions to the development and worldwide implementation of high-efficiency and high-purity cryogenic and non-cryogenic gas separation processes.

Contributions to separations and gas liquefaction

While at Air Products, Dr. Agrawal contributed to improvements in the efficiency of natural gas liquefaction, electronic gases manufacturing, cryogenic processing and gas separation. He led the development of the APX process for natural gas liquefaction that more than doubled the production from a single train. [4] [5] For semiconductor applications, Agrawal invented Column-Plus and Double Column-Plus [6] ultra high purity (UHP) nitrogen and UHP liquid oxygen processes that reduce product impurities to less than one part per billion. [7] [8]

He invented an efficient process to recover refrigeration from liquefied natural gas to produce liquid nitrogen and oxygen. [9] [10]

Agrawal introduced several firsts in the arena of separations using distillation. For multicomponent separations, he introduced a new class of satellite column arrangements and a new superstructure that completed the set of basic column configurations available for distillation. [11] [12] [13] He discovered a solution to the long-standing problem of making highly energy efficient thermally coupled columns operable by making vapor flow between columns unidirectional. [14] [15]

Agrawal presented a generalized framework to convert classical two-way thermal coupling to one-way liquid only transfer, thereby eliminating the challenge involved with the intercolumn vapor transfer between the thermally coupled distillation columns. [16] [17] [18] This enabled the creation of multi-effect distillation analogs of thermally-coupled distillation columns resulting in a further potential for up to 50% reduction in the energy consumption of the already efficient thermally coupled configuration. [19] [20]

Contrary to the assumption that fully thermally coupled systems are the most energy efficient among the basic configurations, Agrawal showed that the thermodynamic efficiency of this system can often be worse than the other configurations. [21] [15] [22] In 2001, for process intensification, he introduced a number of dividing wall column schemes including ones for side rectifier and side stripper configurations. [23] [24]

In 2003, Agrawal extended the concept of using dividing wall columns for batch distillation. [25] Later his team introduced a new class of dividing wall columns and a generalized method to draw the corresponding dividing wall column for any given thermally coupled configuration. [26] [27] [20] [28] [29] First, he led the development of the Shah and Agrawal method to elucidate all feasible basic n-1 distillation column configurations for the separation of an n-component non-azeotropic mixture with n greater than 3, [30] and then in collaboration with professor Mohit Tawarmalani, developed optimization methods to rank-list these thousands to millions of configurations according to their heat duty, exergy, and cost. [31] [32] [33] [34]

Agrawal has also published methods to draw membrane cascades using a limited number of compressors for high recovery of products at high purity. [35] [36]

In analogy to multicomponent distillation configurations, he introduced membrane cascade schemes for multi-component gas separation. [37] [38] [39] These membrane cascades can also be utilized for liquid separations by replacing compressors with pumps.

Contributions to renewable energy

Since joining Purdue University in 2004, Agrawal has focused on creating more energy-efficient and low-cost processes for generating renewable energy. [1] He has outlined novel biomass conversion processes in which no biomass carbon is left unconverted to fuel. [40] [41] He suggested: (i) use of H2 from a renewable energy source in processes such as H2 CAR, and (ii) an H2Bioil process with biomass hydropyrolysis at a high pressure followed by immediate downstream hydrodeoxygenation to yield high energy density oil in two simple steps. [41] [42] [43] [44]

The H2Bioil process was successfully demonstrated through experiments and several companies have adapted the process and its variations. [45]

Agrawal has proposed methods for the solution-based fabrication of thin-film inorganic solar cells. For the nanoparticle ink-based route, his group achieved the highest inorganic solar cell efficiencies for Cu2Zn(Sn,Ge)Se4 (9.4%) and Cu(In,Ga)Se2 (15%). [46] [47] [48]

His team was the first to synthesize (1) Cu2ZnSnS4 nanoparticles [49] [50] and tailor the bandgap of Cu2ZnSnSe4 through partial substitution of Sn with Ge, and Cu with Ag; [51] [52] [53] [54] and (2) promising Cu3AsS4 and their thin films for solar cells. [55] [56]

Agrawal and his team devised an integrated solar thermal power cycle with daytime coproduction of hydrogen and electricity along with H2 storage followed by nighttime combustion of stored H2 using water as a working fluid to supply electricity around the clock with calculated overall sun to electricity efficiencies of 34% to 45%. [57] [58] This cycle stores energy with efficiencies similar to batteries but at a much higher storage density. [59] [58] To address the intermittency of solar energy, for storage of electricity at GWhr levels, Agrawal devised cycles using hydrocarbons and liquid CO2 as circulating fluids to supply electricity around the clock. [60]

Agrawal's current research is on the use of photovoltaic (PV) modules on agriculture land to cogenerate electricity while producing food, the concept of PV aglectric farming. [61] Unlike current PV modules that block sunlight and damage crops, Agrawal's group has suggested new PV modules that divert solar spectrum photons to plants while using the rest for electricity generation. [62] [63]

In collaboration with a team of experts from the Colleges of Agriculture and Engineering at Purdue University, he is leading an experimental and modelling study at the Purdue University's farm to demonstrate the concept of PV aglectric farming for major crops such as corn and soybean. [64]

An oil refinery or petroleum refinery is an industrial process plant where petroleum is transformed and refined into products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemical feedstock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha. The crude oil feedstock has typically been processed by an oil production plant. There is usually an oil depot at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products. In 2020, the total capacity of global refineries for crude oil was about 101.2 million barrels per day.

<span class="mw-page-title-main">Continuous distillation</span> Form of distillation

Continuous distillation, a form of distillation, is an ongoing separation in which a mixture is continuously fed into the process and separated fractions are removed continuously as output streams. Distillation is the separation or partial separation of a liquid feed mixture into components or fractions by selective boiling and condensation. The process produces at least two output fractions. These fractions include at least one volatile distillate fraction, which has boiled and been separately captured as a vapor condensed to a liquid, and practically always a bottoms fraction, which is the least volatile residue that has not been separately captured as a condensed vapor.

In chemical processing, a packed bed is a hollow tube, pipe, or other vessel that is filled with a packing material. The packed bed can be randomly filled with small objects like Raschig rings or else it can be a specifically designed structured packing. Packed beds may also contain catalyst particles or adsorbents such as zeolite pellets, granular activated carbon, etc.

Batch distillation refers to the use of distillation in batches, meaning that a mixture is distilled to separate it into its component fractions before the distillation still is again charged with more mixture and the process is repeated. This is in contrast with continuous distillation where the feedstock is added and the distillate drawn off without interruption. Batch distillation has always been an important part of the production of seasonal, or low capacity and high-purity chemicals. It is a very frequent separation process in the pharmaceutical industry.
