Peter J. Joyce consults in the general areas of chemical engineering process design, development and scale-up. He has extensive experience in specialty organic chemicals and in precious metal and rare-earth refining.

Mr. Joyce's skills encompass process flowsheet (PFD's and P&ID's) synthesis, evaluation and construction along with pilot plant design and scale-up. As an engineering and maintenance manager he has installed or managed the installation of over 200 capital projects. Within the scope of developing new processes, Mr. Joyce has extensive experience in experimental reactor design and development and start-up for the following reactor configurations: batch, continuous polymerization trains, trickle bed hydrogenation reactors, high pressure autoclaves and laminar flow reactors.

As part of his process flowsheet experience comes the need to develop separations and a recycle stream strategy. These unit operation separations include extensive commercial installation of unit operations: reactive separations of alkyl halides, phenols and cyanide using phase transfer catalysis. He has developed a laboratory scale adsorption column for evaluation of organic vapor adsorption on carbon (and zeolites for polar compounds) along with a published first principals adsorption model. In the flavor and fragrance industry he has installed new distillation strategies using ASPEN and BATCHFRAC for the separation of orange oils, alpha and beta pinene and limonene and their derivatives, esters and tonalid (fragrance) plus additive strategies to break azeotropes. He has scaled up a liquid-liquid countercurrent extraction of carboxylic acids from water using a reciprocating Karr column. In developing specialty chemical separations he has implemented continuous reverse osmosis and ultrafiltration applied to natural processes (natural fermentation). He installed a preparative gas chromatagraph for the separation of C6 alcohols (leaf alcohol). He also had management responsibility for production of flavors and fragrances from spray dryers.

In the precious metal refining arena he has developed new automation strategies for purifying Platinum, Palladium, Rhodium and Ruthenium metal salts along with their filtration plus precious metal recovery circuit design and purification. These include acid digestion strategies, ion-exchange column development, precipitation of base metals and purification of rare-earths. As part of this effort he, along with his engineering team developed a precious metal effluent plant optimization that involved ammonia stripping and inventory control plus a base metal rejection strategy. He also installed a non-precious metal plant-wide material balance that provided insights that kept the plant from bottle-necking due to effluent build-up and thus increased precious metal throughput by 20%.

In the environmental field he has installed and obtain New Jersey permits for exhaust gas packed column scrubbers - NOx, SOx and Acid gases (HCl, H2SO4 etc). He is a co-inventor for a new method for scrubbing alkyl halides - methyl bromide (fumigant), methyl chloride etc.

In designing the capital program for the precious metal refinery he performed detailed cycle time analysis, capital and operating cost estimations, discounted cash flow analysis, energy use and energy and waste minimization. As part of this evaluation he installed a PLC based distributed control instrumentation system. As part of this system was a cost analyzer component that yielded instantaneous data on utilities costs for plant steam, vacuum, de-ionized water, cooling water and electricity demand.

Intellectual Property: Manage and write licenses for use of proprietary technology based on market parameters and organizational goals. Holder of three US Patents on the use of Phase Transfer Catalysis and destruction of fumigants.

Mr. Joyce is the co-founder of Value Recovery, Inc.  ( www.ptcvalue.com ) who have unique technology for removing reactive species from wastewater using phase transfer catalysis and for destroying methyl bromide from fumigation vent streams ( www.valuerecovery.net ). He is also a ChemInnolab™ Partner, a company that supplies complete laboratory technical service/sales service projects or reduce inventions to practice. ( more at www.cheminnolab.com).
