LESER LNG and LPG make gas mobile

Demand for the compressed form of natural gas and petroleum gas is growing steadily and is expected to account for one third of global gas consumption in the medium term. Investments must pay off in the short term in order to remain profitable despite ever shorter supply contracts and trading on energy exchanges.

The shortening and flexibilization of supply chains by combining production and processing steps, e.g. on FLNGs (Floating Liquefied Natural Gas) or FSRUs (Floating Storage and Regasification), make this possible. However, the requirements for such projects are complex. Your supplier must be able to master this complexity of projects and the technical challenges.

LESER ensures reliable functioning and tightness of your safety valves even at cryogenic temperatures of -164°C and pressures up to 155 bar, which are necessary for the processing and transport of LNG. No matter which LNG application, onshore, offshore or even mobile, LESER has the right solution and approval for you.

The LESER Advantage

The requirements for safety valves are manifold from conveying, liquefaction, transport, regasification and subsequent distribution. The LESER product range always offers the suitable product with the Types 526, 441, 459 and the Cryo-POSV optimized for LNG/LPG applications.

Thanks to the modern production technology Nanothightness, LESER achieves a 50% higher metallic tightness than API 527 requires. This still reliably meets the requirements of API 527 even at cryogenic temperatures and can be verified on LESER’s own cryo test bench.

LESER’s extensive network of sales engineers and its own project processing center will help you to deliver gas faster, both for technical requirements and in the execution of your project.

Case Study

LESER LNG POSVs support high plant efficiency in liquefaction process

The Challenge
The liquefaction process must be designed efficiently so that the LNG can be offered economically. The necessary cryogenic media temperatures of -161 to -164 °C represent a challenge for the technical design of the individual components in the plant. This also applies in particular to the safety valves, which must function reliably as the final protection in the event of overpressure, even at the cryogenic process and Russian ambient temperatures. 
Linde expected its suppliers to provide a reliable and punctual delivery in addition to solving the technical requirements.
