Target Audience:The target market is the pine chemical industry and the suppliers of fragrances and flavors. It will also allow for crude sulfated turpentine (CST), a byproduct from paper mills to be used as a low-cost raw material in fragrance and flavor industry to produce fragrances and flavors that are used in cosmetics, personnel hygiene products such as soaps, detergents and shampoos.

What was accomplished under these goals?
In the first year of the project, we accomplished: We modified the bench-scale test unit used in the Phase I tests We have introduced the capability of testing multiple sorbents beds to carry out continuous sulfur removal (one bed adsorbing, while the other one being regenerated). We also introduced the capability of analyzing the regeneration off-gas products to better identify sulfur species in the off-gas to take proper measures to its disposal. We tested various sorbents and screened them based on their performance (e.g., sulfur capacity, activity) and operational capabilities (e.g., life and durability). We designed a stand-alone desulfurization system that will continuously treat 100 g/min pinene (or other terpenes). Please note that this is 10X larger than what we planned in the Phase II proposal (due to the strong commercial interest in the technology, TDA decided to modify an existing unit that can treat a larger flow of pinene and CST, which will elevate the technical readiness level of the technology at the end of Phase II and make it more viable for transition to a commercial technology). We completed a Safe Operating Procedure and acquired all approvals from TDA Safety Officer to run the unit with commercial pinene fractions We obtained pinene and crude sulfate turpentine samples from Swathi Menthol Pinene with 20-50 ppmw of total sulfur Crude sulfate turpentine with 1,500 ppmw sulfur We completed the design of a proof-of-concept prototype unit We modified an existing test skid at TDA to treat 4 barrels of pinene and crude sulfate turpentin. In the second year, of the project we accomplished the following: We have built a regenerable test rig to fully demonstrate the concept We have obtained high and low sulfur piene samples from commercial sources We have carried out proof-of-concept tests to confirm that the commercial samples could be effectively desulfurized with the TDA process We completed an engineering analysis and estimate that the treatment cost (for pinene polishing - i.e., to reduce the sulfur content of low sulfur pinene) will be less than $8/ton

What do you plan to do during the next reporting period to accomplish the goals?With the build-up of the proof-of-concept demo unit is complete and having commercial pinene and crude sulfate turpentine samples acquired, TDA Research is ready to move into the demonstration task. We will evaluate the sorbent and system performance at commercially significant scale. We will complete multiple cycles tests to demonstrate the life of the sorbent. Based on the results, we will complete a comprehensive cost analysis to assess the techno-economic benefits of the new technology.

What do you plan to do during the next reporting period to accomplish the goals?Tasks remaining include: Complete proof-of-concept demonstrations with the prototype unit using pinene acquired from commercial producers (September 2017). Carry out long duration tests to demonstrate life and durability. (September - December 2017) Based on the prototype evaluations carry out a detailed engineering analysis to estimate the size and capital and operating costs of the desulfurization system. (December 2017-May 2018)

We resumed durability testing on the bench-scale. We began initial shakedown of the commercial demonstration desulfurization system. We completed design work for modifications required to integrate the commercial demonstration unit for a field test with a commercial partner. This field-test will demonstrate sorbent and system durability.
