MEA Triazine Contactor Optimization to Increase Efficiency and Reduce Fouling Potential

Liquid absorbents have been utilized for decades to remove impurities from produced natural gas. Throughout the last 15 years, monoethanolamine (MEA) triazine has become an industry-recognized name for the removal of sour gas (H2S). MEA triazine has one of the lowest cost profiles in terms of cost per mass of H2S removed and has obtained a commodity status. It is widely used in the oil and gas industry, both on production (upstream, midstream) and processing (downstream). MEA Triazine is typically applied via direct injection into flowlines or applied in contactor vessels (“scrubbers”, “towers”, “bubble columns”). The application type depends on numerous factors but in general, the application via contactor vessel is preferred due to its increased efficiency. However, due to the many different contactor configurations available, a wide range of efficiencies are achieved, ranging from 50 – 70%. MEA Triazine systems are also known to foul with acid-insoluble polymeric solids. This occurs when the MEA Triazine and its reaction products are not managed properly, or the system is not designed for the specific conditions. The spent material, commonly referred to as dithiazine, can form solids (amorphous dithiazine) in the contactor packing, post contactor separator, or in downstream pipelines if carry-over occurs. This paper aims to provide the reader guidance on how to optimize MEA Triazine contactor vessels to achieve maximum efficiency and to reduce or eliminate fouling. Optimization principles discussed will include contactor configurations, contactor modifications, and MEA Triazine properties and its effect on system performance. Increasing system efficiency and eliminating solids formation in these systems will have a direct impact on the user’s operating expense (OPEX). This is due to better scavenger utilization and a reduction in maintenance and downtime due to solids formation. A reduction in scope three emissions will also be achieved.

PHMSA Gas Pipeline Mega Rule

The Pipeline and Hazardous Materials Safety Administration (“PHMSA”) recently released the final rule known as the “Mega Rule” which includes a set of regulations designed to improve pipeline safety by reducing the frequency of pipeline failures. The intent of the rule is to address lessons learned following the Pacific Gas and Electric Company rupture and release in San Bruno, California, in September 2010. On September 9, 2010, a natural gas pipeline owned by Pacific Gas & Electric (PG&E) exploded in San Bruno, CA. creating a fire that killed eight people, destroyed more than 100 homes and cost $2.8 billion. An investigation by the National Transportation Safety Board (NTSB) found that PG&E had a faulty integrity management (IM) system that failed to detect a defective section of the pipeline resulting in the devastating explosion. The PG&E incident spurred action from the Pipeline and Hazardous Materials Safety Administration (PHMSA) to revise the existing Federal Pipeline Safety Regulations (FPSR) to improve the safety of onshore gas transmission pipelines. These revisions are known as the Mega Rule. This final rule responds to the incident by extending existing design, operational and maintenance, and reporting requirements under the Federal Pipeline Safety Regulations to onshore natural gas transmission pipelines and gathering pipelines in rural areas. The Mega Rule is a sweeping set of regulations comprised of three parts: • Part 1 focuses on the safety of gas transmission pipelines. • Part 2 introduces new guidelines about IM, updated requirements for high consequence areas (HCAs) and expectations for operators following extreme weather events and natural disasters. • Part 3 expands certain safety requirements to all onshore gas gathering pipelines.
