SEMBCORP takes control with Automatic pumps traps
Two automatic pump traps from Spirax Sarco have helped solve a serious control issue for
Sembcorp, one of the UK's leading industrial utilities and services companies. The pump traps
prevent the company's gas heater from stalling, which was previously making it difficult to control
the gas temperature. Sembcorp uses gas to produce electricity in its own power generation plant on
Teesside, as well as distributing gas to some of its industrial customers. The company must heat its

gas supply to 40°C to prevent it freezing as it enters lower pressure lines downstream. "Since we've
installed the pumps traps the improvement has been dramatic," says Development Manager,
Dr. Michael Capstick. "Prior to the new systems being installed the gas temperature varied widely,
