PHOSPHORIC ACID |

We provide consulting and basic engineering services for new and existing phosphoric acid plants.We actively support advancement of phos acid technology and have supported and developed valuable innovations. A brochure describing technology and listing phos acid projects is available upon request at JohnWingPE@verizon.net.

Processes

Dihydrate:Process design for several expansions and many modifications. Experience as Asst. Phos Acid Plant Supt., Tech Services Supt., &R&D Engr.
Hemi:Designed 2 very successful conversions from Dihydrate to Hemihydrate Consulted for 4 new Hemi plants.Studied conversion of several plants to Hemi See the Hemi page in this website.
Hemi-Di:Studied conversion of 5 phos acid plants to Hemi-Di. Basic engineering to convert Oswal plant to Hemi-Di. Construction was started but not completed after another company bought facility.)
Evaluations to select process: Advise clients regarding Dihydrate vs. Hemi

Equipment

Reactors:Projects with most brands, including Prayon Mark 2,3,&4, Yara, Jacobs-Dorr, Oxy Hemi, & Chemico. Converted two Prayon reactors to Hemi
Filters:Tilting Pan: Delkor, Eimco (FL Smidth), Landskrona, Pannevis, Phillippe Tilting Pan: Bird-Prayon (Andritz) with 3 types of central valve, including modern EX-LV. Table:Ucego (RPA)
Evaporators: HiTech Solutions: We provided complete design of evaporators, including entrainment separators & FSA units. Swenson, Struthers, Krebs, etc.
