SPARKS, Nev., August 2, 2005 – SulphCo, Inc. (OTC Bulletin Board: SLPH) announced today that it has completed construction and testing of its first 2,000 barrel/day Sonocracking plant. The plant components which are currently being shipped to Korea will be installed at the OIL-SC customer site in South Korea later this month.

The 2,000 barrel per day plant consists of several major components including stainless steel process tanks and piping, automatic valves and metering devices, dehydrating units, and control panels with touch screen PLC logic. The plant also contains the critical Sonocracking ultrasonic components and power supply.

The plant was designed by the SulphCo engineering staff and the various components were constructed by SulphCo as well as third party suppliers in both Germany and Taiwan. The plant was designed and constructed to meet the South Korean permitting codes which necessitated the inclusion of mandatory explosion proof design parameters.

According to the contract with OIL-SC, SulphCo has also delivered to the customer site in Korea sophisticated laboratory analytical equipment including an automated crude oil distillation system and a gas chromatograph along with other laboratory equipment.

The equipment testing included a combination of pressure testing and life-cycle testing according to internal SulphCo quality control procedures. “We have passed a very important hurdle in this company’s growth from research and development to commercial operations,” said Peter Gunnerman, President and COO of SulphCo Inc. “Considering that these first unit components were designed by the SulphCo engineering staff in Sparks and built overseas on a timely basis and with a high degree of sophistication and quality is a significant milestone.”

The 2,000 barrel per day plant will be used by OIL-SC for technology demonstrations as part of OIL-SC’s marketing assistance to SulphCo for South Korean refiners and other potential customers in Asia.
