success stories

Chevron Oronite is committed to making improvements to its facilities that make a difference in how we consume energy, manage carbon emissions and handle waste product. Here are some examples of how we promote sustainability in our business.

new technology used to reduce sulfonate waste

sulfonate detergent unit in Gonfreville, France
New technology has helped reduce solid byproducts of high overbased sulfonate by about 4,000 metric tons per year at this sulfonate detergent unit in Gonfreville, France.

The production of high overbased (HOB) sulfonate, a detergent used in additive packages, creates a sludge-type waste. With new technology using decanters in the production process, Oronite has been able to recycle more of the waste material, reducing the solid byproducts at its plant in Gonfreville, France, by about 4,000 metric tons per year. Previously, this sludge waste was sent off site to be incinerated. By managing the waste on site, Oronite reduced the raw material carbon footprint of sulfonate production by approximately 16 percent. Soon, this method will be extended to the carboxylate production units in both Gonfreville and Singapore to promote further waste reduction at its plants.

Singapore manufacturing lauded for energy efficiency, reduced greenhouse gas emission

Ongoing work to improve energy efficiency and reduce carbon emissions at our Singapore manufacturing plant
Ongoing work to improve energy efficiency and reduce carbon emissions at our Singapore manufacturing plant was highlighted in a recent speech by the Minister for the Environment and Water Resources, Masagos Zulkifli, to the Singapore Parliament.

Masagos Zulkifli, Minister for the Environment and Water Resources, cited Oronite as an example of a company that can pursue both growth and environmental sustainability, and noted that it had achieved “annualized energy savings of $1.8 million and a carbon abatement of 4,800 tonnes by installing new equipment,” according to The Straits Times article (3/20/18). “The improvements referenced included a waste heat boiler and mechanical vapor recompression system installed as part of the Carboxylate Expansion Project,” said Kathiresan Marimuthu, who was the project engineering manager. The Singapore Parliament recently passed a bill which will require all facilities producing 25,000 MT or more of greenhouse gas emissions in a year to pay a carbon tax starting in 2019.
