Kay Au

Technical Level II

Kay Au is a chemical engineer with experience in process engineering and process and instrumentation diagrams (P&IDs).

Visual Assessment

Project Engineer, San Diego Integrated Master Plan, San Diego Public Utilities

Department, San Diego, California. The San Diego Integrated Master Plan project requires visual assessment of over 180 facilities and 10,000+ assets owned by San Diego

Public Utilities Department (SDPUD). Potable water distribution and treatment facilities, wastewater collection and treatment facilities, raw water pump stations, and recycled water facilities are among the facilities in which visual assessment was conducted. The visual assessment is an integral part of the SDPUD Integrated Master Plan (IMP) as it takes up a significant portion of the IMP. Moreover, assessments of the IMP help update the

SDPUD’s current asset management program and allow SDPUD to prioritize future capital improvement projects. Au has conducted visual field assessments of pump stations and wastewater facilities, identifying assets while assessing their conditions.

Prior to CDM Smith

University of California, Los Angeles

Student Engineer, Los Angeles County Sanitation District (LACSD), Compton, California. Kay was responsible for the integration of digital filing, sorting and reviewing over 1,000 manholes and pipes in surrounding counties utilizing ArcGIS and Excel.

Working on the flow monitoring project, she inspected manholes and took note of their conditions for the purpose of rehabilitation.

Ethylene Cracking Section Lead, Electrified Ethylene Plant (Capstone), UCLA, Los

Angeles, California. For her capstone project, Au and her team were tasked with designing an electrified ethylene plant, with each person assigned to a single piece of equipment. Au’s equipment was the ethylene cracking furnace, where she had to design and optimize its performance while keeping costs low. To do this, Au ran multiple case studies to maximize the amount of product is made at the lowest duty possible, comparing multiple options down to the dollar. She calculated capital and operational expenses of all equipment involved with the cracking furnace, including pumps, valves, and flash drums.

Because an electrified cracking furnace is not yet commercial, Au was required to conduct extra research on firing methods and therefore the inner coils and their arrangement. She was also responsible for creating a simulation of the cracking furnace, as well as a master process flow diagram (PFD) of all equipment involved in her section (oil quench, water quench, etc.).

Lead Undergraduate Researcher, UCLA Nanomaterials and Membrane Technology

Research (NanoMeTeR) Lab, UCLA, Los Angeles, California. Ms. Au was involved in research concerning mostly reverse osmosis membranes as well as ultrafiltration membranes for the purpose of desalination. She is familiar with high pressure membrane testing with the crossflow system, as well as a stir cell, up to 3000 psi. She also conducted lab scale experiments, synthesizing thin-film composite (TFC) membranes. She was

Kay Au responsible for the training of new undergraduate lab students to use high pressure systems and PhD students to synthesize TFC membranes. The study aimed to find the role transmembrane pressure and flux in membrane compaction and therefore the membrane’s performance. In sum, her research and its implications were that higher transmembrane pressure induced greater compaction, therefore structural deformity, but also greater salt rejection.

Product Development Engineer Intern, Henkel, Irvine, California. Ms. Au assisted the product development team, where she made and tested batches of conductive die-attach paste to measure the bleed, bond lines, and fillet on various semiconductor substrates to assess favorability. At the manufacturing plant, she assisted in the design and improvement of an ultrasonic cavitation process, where she was able to successfully break up agglomerates of die attach paste intermediates, decreasing the traditional time necessary to do so. Additionally, Au, along with a lab mentor, decreased the viscosity to a target centipoise value for a non-conductive encapsulating underfill. She assisted in meeting clients’ needs for die attach film by testing change in mass using a thermogravimetric analyzer.

Chemicals/Upstairs Team Member, Chem-E-Car, American Institute of Chemical

Engineers (AIChE), UCLA, Los Angeles, California. Chem-E-Car is a competition hosted by AIChE that engages aspiring engineers to build a shoebox-sized car powered by a chemical energy source. Regional competitions first occur, with the winners proceeding to the annual student conference. As a member of the upstairs/chemical team, Ms. Au was responsible for functionalizing a previous year’s aluminum air battery to generate enough current and voltage to run our 3D-printed car. She instead redesigned the final battery configuration so that it could power our car, generating 9 volts and 1 amp. Ms. Au was also responsible for preparing and finalizing the chemicals and concentrations for day of competitions, pre-building all battery cells and executing test runs. An Engineering Design

Process (EDP) was formulated, and Au represented her upstairs team at regionals and student conference.
