A New Orleans-based private equity firm has announced the acquisition of a Houston chemical company's technology business unit, the business announced today.

Black Bay Energy Capital acquired a portion of Merichem Company’s business — including its Merichem Process Technologies and Merichem Catalyst Products, which will collectively be renamed Merichem Technologies. Merichem's caustic services business, which handles spent caustic for beneficial reuse, will be maintained by the company.

Cyndie Fredrick has been promoted to CEO of Merichem Technologies. She previously served as Merichem's senior vice president and general manager of Merichem Process Technologies. She's joined by CFO Rene Campos, Senior Vice President of Technology Jeff Gomach, and Senior Vice President of Catalysts William Rouleau, who are all former managers within Merichem.

“The Merichem Technologies team has successfully deployed highly engineered and patented technologies, chemical catalysts, and mechanical solutions to various end markets including liquified natural gas, midstream oil and gas, refining of traditional crude and renewable feedstocks, biogas/landfill/RNG production, geothermal energy production, and chemical manufacturing," Fredrick says in a news release. "Merichem Company has been a fantastic steward of this business for decades, and the entire Merichem Technologies team is excited about our new partnership with Black Bay and the ability to pursue new avenues for growth.”

Additionally, Merichem Company's CEO Kendra Lee will join the Merichem Technologies board. Lee's grandfather founded the company in 1945, and she told EnergyCapital last year that she hopes to continue the legacy of the company, which designs and fabricates equipment for sulfur removal.

“Our reputation has always stood on the principles of proven performance, unsurpassed expertise, and an uncommon commitment to our customers," Lee says in the release. "This divesture is a major milestone for Merichem Company as we continue to execute on our strategic vision, further cementing our leadership position in caustic services.”

Black Bay focuses on the energy and specialty chemical sectors, but the Merichem Technologies acquisition brings a new sulfur-treating platform to the firm.

“Sulfur treatment is a critical path item across many industrial applications around the world. Hydrogen sulfide, mercaptans, carbon dioxide, and other related impurities must be dealt with to ensure environmental compliance, sustainable operations, and a saleable end product," Tom Ambrose, partner of Black Bay, says in the release.

Kendra Lee had no designs on running the family business.

“In fact, I never planned on being a part of Merichem,” Lee recalls.

In 1945, Lee’s grandfather, John T. Files, and a pair of business partners founded the company in Houston. Their goal was to take a potential waste product and turn it into something that would benefit the oil and gas industry — an early attempt at sustainability.

What started as a soap and industrial cleaning company began procuring cresylate, which is a waste from the refineries treating gasoline, to recover spent cresylic acids, which are highly caustic, and refine them so they could be sold into the industrial chemicals market.

“When we were founded, we were a chemical company,” says Lee. “Today, we have morphed into a technology company.”

That transformation began in the 1970s. By 1997, when Merichem put the chemical end of their business into a joint venture with Sasol, the focus had transferred to Merichem Process Technology and Merichem Caustic Services, while Sasol took over the chemical branch.

Merichem Process Technology designs and fabricates equipment for sulfur removal, while Merichem Caustic Services works with companies to handle spent caustic for beneficial reuse rather than waste. The innovative company has more than 1,200 units licensed globally for operation in a myriad of applications. Those allow the 78-year-old company to further push sustainability as a priority.

Lee began her career with Merichem more than 20 years ago as an entry-level laboratory technician.

“I’ve never left, and I kept getting opportunities — now here I am,” she says.

Where she is is at the top of the ladder. Lee became chairman of the board in 2012 and CEO in 2014. But doesn’t think of Merichem as a family business. Lee is only the third member of the family to work at the company, including Files and the cousin who followed him as CEO.

Lee says that she seldom spoke to her grandfather about the business. He worked at Merichem until the day he died in 2002, but Lee recalls that, as a low-level employee, she didn’t have a single meeting with him before that time.

“Our interactions were very normal family dinners,” she explains.

Since her transition into leadership, Lee says, “My focus has really been on continuing the legacy my grandfather and cousin created. We’re very employee-focused and community-focused. Part of our role as part of our industry is to provide livelihoods and be good stewards in communities in which we operate.”

She adds that she’s also focused on innovation.

“That was a big part of who my grandfather was. That’s how we transitioned from being a chemical company to a technology company” she says. That means looking for new methods not only in the research facility, but in every segment of the company.

That eye toward the next big discovery will likely see a significant payoff in one to three years, when a new product, designed to improve on hydrogen sulfide removal — with a new catalyst that is regnerable — will be commercially available. But right now, customers can take advantage of the company’s new Standard LO-CAT® system. The product is the result of continuous improvements from the previous system and boasts low operating costs, no liquid waste streams, and significant turndown capability.

And what will follow for the Houston born-and-based company? Merichem has plans to push further into the renewables field, says Lee, adding that there is a continued need for Merichem’s technology as we transition into other types of energy, including geothermal. More than three quarters of a century after its founding, Merichem is still a company on the forefront.

Houston scientists unveil faster, low-energy method to recycle lithium-ion batteries

Battery breakthrough

Rice University researchers have uncovered a more energy-efficient and faster way to recycle critical minerals from used lithium-ion batteries.

Traditional methods rely on high heat, long processing times and harsh chemicals to recover a small fraction of critical materials from batteries used in everything from smartphones to electric vehicles. However, the team from Rice's Department of Materials Science and Nanoengineering developed a process that uses a water-based solution containing amino chlorides to extract more metals in less time

The team published the findings in a recent edition of the scientific journal Small.

Simon King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute, served as first author of the study. He worked with corresponding authors Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Sohini Bhattacharyya, a research scientist in Ajayan’s lab.

By using a hydroxylammonium chloride (HACI) solution, the team achieved roughly 65 percent extraction of key battery metals in just one minute at room temperature, according to the study. The efficiencies grew to roughly 75 percent for several metals under longer processing times.

“We were surprised by just how fast the reaction occurs, especially without the involvement of high temperatures,” King said in a news release. “Within the first minute, we’re already seeing the majority of the metal extraction take place.”

By not requiring high temperatures or long reaction times, Rice predicts the process could have a major impact on cost and the environmental impact of lithium battery recycling. Additionally, the water-based HACI solution makes waste handling easier and lowers certain environmental risks.

In addition to extracting the materials, the team went on to demonstrate that the recovered metals could be recycled and reprocessed into new battery materials.

“A big advantage of this system is that it works under relatively mild conditions,” Ajayan added in the release. “That opens the door to more sustainable and scalable recycling technologies.”
