The manufacture of monosodium phosphate from wet process acid by amine extraction
… for hydrochloric than for phosphoric acid. If wet process phosphoric acid is used, the impurities must be separated in some way from the final product. The work described here involves a study of the distribution of phosphoric acid itself, and the impurities trivalent iron and sulphate, between …

Purification of phosphoric acid by solvent extraction
… a feasibility study (187) which suggested that a process for purifying wet-process phosphoric acid by solvent extraction should be economically viable. The work was divided into two main areas, (i) chemical and physical measurements on the three-phase system, with or without impurities; (ii) …

Performance Characteristics of Polyethylene Terephthalate (PET) Modified Asphalt
… testing. The binder testing was conducted on wet process blends produced with a high shear mixer at PET contents of 5, 10, and 15 percent by weight of the binder. Dynamic Shear Rheometer (DSR) and Rotational Viscosity (RV) tests were performed on the unaged and Rolling Thin Film Oven (RTFO) …

Impact of waste plastics on asphalt concrete chemical and environmental characteristics
… separation. When 3% LDPE is added in the wet process, the potential for AC rutting would be increased, while the cracking potential would be maintained. However, waste plastic-modified AC may not outperform the potential performance of SBS-modified AC. Leachate testing of waste …

Controlled release of Isothiazoline biocides from industrial minerals
… by way of using a bench high shear mill (dry process), or combining them to hydrated minerals (wet process). The characterisation of the minerals was achieved by XRF (chemical composition), XRD (crystal composition), SEM (morphology), B.E.T nitrogen (surface area), and Light Scattering …

Incorporating Recycled Plastics in Asphalt Binders and Mixtures
Plastic has become an unavoidable material in modern life, and its existence spans from food packaging to transporting goods. Due to the low cost and durability of plastic products, the growth in plastic production has been increasing exponentially. The increased production increased plastic waste. …

Performance of hot mix asphalt using peat modified asphalt binder
… where the mixes were prepared according to the wet process. Mechanical testing on the PNpt asphalt mixes have demonstrated that the asphalt mix stiffness, rutting performance at high temperature were found to be improved. Modification indices with the PNpt 5% showing a peak modification with …

Analysis of rbd palm olein abrasive blasting as new metal surface cleaning method
Abrasive blasting is a process done for surface cleaning which has two methods which are dry or wet process. The dry process which uses abrasive media blasted onto a surface to clean dirt on the surface normally will release fine dust into the environment. Water is used with abrasive media to …

Solvent extraction of phosphoric acid
… literature survey on the purification of wet process phosphoric acid by organic solvents is presented and the literature describing the design and operation of mixer-settlers has also been reviewed. In batch studies, the equilibrium and distribution curves for the systems water-phosphoric …
