Chief Process safety Engineer - ABB Lummus Global

Responsible for activities in safety related engineering,

design, training and consulting services as part of project

support for all phases of project execution within Foster

Wheeler and ABB Lummus Global. These responsibilities

include functions in Process Safety to ensure safe plant

design and compliance with applicable codes and standards.

Completed several process plants safety studies for

refineries and chemical plants. This included HAZOPs,

SIS/SIL Reviews, LOPA, evaluation of over pressure relief

system, relief valves, flare basis of design, flare

hydraulic calculation using state-of-the-art computer

simulations. Process plants included Ethylene Plants,

Hydrotreaters, Hydrocrackers, Hydrogen Plants, Sulfur

Plants, LNG, FCC, Delayed Coker, Visbreaker, Crude/Vacuum,

and various offsite and OSBL facilities.

Prior to joining Foster Wheeler, had extensive refinery

experience including offsite/utilities including the

following:

. Effluent Water Treatment Project, which included a pilot

plant setup and operation, PFD and design document

preparation.

. Design of process units including crude and vacuum units,

delayed cokers, and offsite facilities in two petroleum

refinery expansion and modernization projects. Associated

with the projects were fieldwork for data collection of

utility systems, pressure relieving and flare systems,

interconnecting piping, and product tankage.

. Three field assignments for troubleshooting and

recommendation of cooling water systems.

. Design of a new flare system for a refinery and incorporate

existing systems in the new design.

Also had several technical support assignments, which

included unit start-up and debottlenecking. Provided

technical and process services for a grassroots refinery to

replace an existing one. This included several

hydrodesulfurization processing units for gas, oil,

kerosene, and atmospheric residue. Other units included are

Completed a HAZOP study for a chlorine manufacturing plant.

The study focused on the hazards associated with the

chlorine and hydrogen process circuits in the plant. The

study included training of client personnel on HAZOP

techniques.

Completed a HAZOP study for a project to recover high-grade

olefin from several off-gases and knockout liquids

associated with an ethylene plant. The HAZOP study focused

and included a detailed review of the engineering flow

diagram. The study included training of client personnel

on the HAZOP techniques.

Completed a preliminary facility assessment of the sulfuric

acid plant as part of California Risk Management and

Prevention Program (RMPP). Also completed a HAZOP study for

a sulfuric acid manufacturing plant and an ammonia scrubber

to treated SO2 and SO3 off gases from the sulfuric acid

plant. The study focused on toxicity of these chemicals to

comply with California environmental restriction. Several

toxic release scenarios were identified that impact the

public and require dispersion modeling.

The study included training of client personnel on HAZOP

techniques.

Provided technical assistance in training for and

conducting HAZOP studies in several tail gas treating and

recovery units for TOSCO Refinery in California. The study

focused on release of Acutely Hazardous Materials (AHMS)
