Case Studies

A high-purity silicon material manufacturer was looking for a solution to ensure a positive shutoff of gas flows. The company produces 500 tons of high-purity silane gas, 1,000 tons of electronic grade polysilicon, and 18,000 tons of granular polysilicon annually.

To comply with the Clean Air Act, a coal-fired power plant needed to heat flue gas to 455°C (850°F). Watlow engineered a customized design that would meet the customer's needs.

Unlike traditional proportional or even PID control that require a varying output to a modulating control device, time-proportional control can achieve a proportional control response to process variation using an on/off device by varying on and off times in a defined control period.

A local power plant was having issue with clogged nozzles. The nozzles that spray the ammonia to neutralize the NOx began to clog forcing the customer to take the units off line. Because of this, they were not able to produce power at peak time to their customers. Valin designed and assembled a turnkey filtration system that consisted of 10 filtration assemblies with filter housings (for pre-filtration and final filtration), a differential pressure gauge, drain valves on the bottom of filter housings, inlet and outlet valves, and a support stand.

An oil production company was having problems with the freshwater flow lines freezing up in the vertical sections that go through the permafrost layer. All of the frozen lines stemmed from the self-regulating heat trace cable they were using which kept burning out. It would short out at the bend required to fit it down inside the 1” thermowell pipe. The secondary problem was the lack of sufficient heat output when self-regulating heat trace is folded back on itself. With each failure came thousands of dollars in lost production, down time, labor and materials to thaw the line.

During an observation at a refinery, chemists noticed the sample cylinders currently installed at their facility did not have the latest features specified by the Department of Transportation (DOT) / Cal-OSHA regulations.It was reported to the quality control division where the risk was recognized and resulted in an action item that the Maintenance & Reliability team had to resolve. Valin assessed the issue and recommended replacing the rupture disc with a bushing and relief valve, set at 1800 psi. The recommendation was reviewed with the Instrument Mechanical team leader, a QCD stake holder, the local PED representative for PRVs, the ETC sample gas cylinder subject matter expert, and the PRO maintenance planner/scheduler. Everyone agreed that the change should be implemented and Valin was called in to handle the installation.

A developer and manufacturer of molded-fiber packaging was struggling with controlling the consistency of the pulp feed stock in their manufacturing process. They tried numerous solutions with little to no success. This was due in large part to the fact that they were forced to use numerous vendors for the equipment needed to control their pulp consistency. Their supplies did not offer a full solution to measure, control, and automate their process. The outcome was an inconsistent product that would burn due to a thick pulp stock that dried too fast, or wet stock that took excessive time to dry and wasted time and resources.

There are 27 mines located in a geographically isolated area using fittings and tubing provided by Valin.  Unfortunately, Valin did not have a local office to support the mines with a bin stocking program. To combat this Valin looked at the areas local resources to see if we could partner up with a local vendor that is currently in the mines and can present Valin products to the mines. After an extensive search, a partner was found that had a good reputation and could expand our presence in the mines. 

A major refinery in California turned to Valin to help them solve a problem with their sample cylinders.
