Here is a new concept for the production of purified benzene, about 98 wt% pure, while coproducing ethylene via steam cracking. The purified benzene is of adequate purity to meet the growing market demand for aromatic alkylates and cyclohexane. This method could be used for disposal of dilute benzene (10-20 vol%) obtained from refinery sources while reducing the Reid Vapor Pressure (RVP) of the gasoline pool and increasing the poolís octane numbers.

David Netzer Experience spans over 40 years in process engineering and technology. The experience was acquired with major E & C organizations and licensors of process technology. Significant part of the experience is related to petroleum refining, including: hydroprocessing and sulfur plants, natural gas, including L.N.G, CO2 enhanced oil recovery, ethylene and other petrochemicals. Extensive conceptual design experience on coal gasification projects. Author of 12 publications and 12 patents.

Holds a professional engineering license from states of New York and Illinois. Only consulting services are offered in Texas - no engineering.

Among the 12 patents, three are of strategic significance:

  • US Patent 5,880,320 and the European equivalent 1,017,651 and equivalent patents in China ZL 98809853.9 and India 196,730. These patents are dealing with an integrated production of ethylene and styrene via dilute ethylene from steam cracking.
  • US 6,177,600 alkylation of lower purity benzene to produce ethylbenzene.
  • US 6,677,496 benzene production from catalytic reforming while co producing olefins and increasing the octane of the gasoline.

Accomplishments:
  • 2012-2013—Evaluated several options for conversion of an idled petroleum coke gasification facility for restarting in a more profitable role. The facility was originally designed to produce gas turbine fuel and the objective of the consulting assignment was to help PBF Energy find an optimal scheme for producing higher value chain of liquid products. The scope involved market studies, conceptualizing the conversion, economic analyses of plant investment and product slate marketability. Also, evaluating operational, marketing and regulatory issues associated with methanol gasoline blending and analyzing integration of methanol production with PBF Energy's Delaware City refinery.
  • 2010-2011—Developed an improved concept for producing methanol as a gasoline blending component and using solid fuels such as petroleum coke as a feedstock. (See articles from June/July 2011 in Oil & Gas Journal). As a reference case, we used the US EPA mandated blending 10 volume% ethanol in gasoline. The concept was presented to Oil Sand Heavy Oil Conference in Calgary, Alberta, Canada in July 2011 and also to CMAI methanol conference in San Diego, California in December 2011. See Powerpoint presentation.
  • 2008-2009—Process consultant for Conceptual design of 125,000 bpsd bitumen refinery for Alberta First Nations Energy Centre in Canada.
  • In 2007 was selected by Agrium Inc. Calgary, Canada to provide consulting services and process review for a proposed ammonia / urea feedstock conversion project in Kenai, Alaska. The proposed conversion was conceptualized by major contractors and licensors and uses coal feed as opposed to the present natural gas feed.
  • 2005 - David Netzer, leading a team of consultants, was awarded a study led by the province of Alberta in Canada and 18 industry sponsors. www.energy.gov.ab.ca The feasibility study, see attached news item from National Post in Canada, †will lead to a $7.0 Billion bitumen upgrading refinery integrated with petrochemicals, ammonia synthesis gas and electric power generation. The key products will be diesel, gasoline, kerosene, ethylene, propylene and ammonia synthesis gas.
  • The following is a partial list of the sponsors: BP, Petro Canada, Dow Chemical, Nova Chemicals, Agrium, BOC, Air Products, Trans Alta and Sinopec
  • 1995 - Conceived the idea that led to the olefins recovery and polypropylene production at BP ( old Arco) refinery in Los Angeles.
  • 1977 - Developed a coal gasification concept based on integrating BGC ( British gas/Lurgi) and Texaco that led to extremely competitive process, patent US 4,211,540.
  • 1978 - Was a key member of the process team that developed the initial phase of the Tennessee Eastman coal to carbon monoxide project.

List of Recent Clients:
  • SK Energy - Teajon, Korea - Client representative in USA on a confidential coal gasification project.
  • SRI Consulting - Menlo Park, California -Completed seven multi clients evaluations on petroleum refining petrochemicals and LNG.
  • Gibson Energy - Calgary, Alberta Canada - Project technology evaluation for aromatics and gasoline components.
  • BOC - Murray Hill, New Jersey - Process consultant on refineries and petrochemicals.
  • Lurgi Oil & Gas - Frankfurt, Germany - Agent-Consultant on propylene production technology for refinery applications in the U.S.
