Is pinch enough?

Back in the late 1970’s and early 1980’s when fuel gas prices were high, energy utilization assumed major importance. A new method of calculating heat exchanger networks was developed. It was called Pinch Technology. Today pinch has been rediscovered by engineers who have access to fast computer simulation models. But as occurs with any older method that is rediscovered by a newer generation, enthusiasm generated by the rediscovery tends to obscure the deficiencies ...

LO-CAT® process for waste water treatment plants

In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOX emissions from the on-site combustion of the gas could be kept within acceptable regulatory limits, allowing the gas to be burned on-site to generate steam for ...

BCMT™-500 and BCMT-500-LRT

Too often profitability is lost because refiners lack adequate accessibility and bottoms cracking power in their catalyst. Albemarle has developed BCMT-500 additive, which features high accessibility and provides powerful functional bottoms conversion sites. BCMT‑500 delivers many pre-cracking sites and high metals tolerance while making up only a small fraction of the circulating catalyst inventory. BCMT-500-LRT provides refiners with the same accessibility, metals ...

Want to make ULSG from your FCC unit?

Topsoe’s new superior FCC pretreatment catalysts provide high HDN as well as HDS. Legislations worldwide push towards lower sulfur emissions from diesel and gasoline vehicles, forcing refiners to rethink their fixed assets to meet new product specifications. Topsoe’s new HyBRIM™ catalysts allow for more severe FCC feed pretreating which ultimately improves operation of the FCC unit leading to better products. TK-569 HyBRIM™ offers the highest activity ...

DuraSOx™

Highly attrition-resistant SOx reduction additive without performance compromise. DuraSOx SOx reduction additive is the culmination of intensive development work focusing on obtaining the most attrition-resistant Sox additive on the market without any performance compromises. It follows in the footsteps of Albemarle’s longest marketed SOx additive, KDSOx®, in that both take advantage of Albemarle’s patented hydrotalcite technology. SOx reduction additives are ...

Diagnostics™ Leak Study Optimise Ammonia Synthesis Loop

How can Tracerco help optimise performance in my ammonia synthesis loop? If you are trying to determine why the ammonia synthesis line is not performing as efficiently as expected, a series of tracer tests can be carried out for troubleshooting the different processing loops of ammonia synthesis and converter lines. Tracerco Diagnostics™ Leak studies have proven invaluable in identifying potential areas or locations of leakage within an ammonia synthesis processing loop, converter, ...

Chemical process industry

The chemical process industry has always been the driving force for Sulzer Chemtech’s innovations. In the early 1960’s, the stringent requirements for the purification of heat-sensitive fragrances led to the development of the Sulzer Packing BX, which set a new standard for vacuum distillation and led to the development of many other unique products. For classical column operations like distillation, absorption and extraction, and for alternatives such as crystallization, ...

Oil sands crude — profits and problems?

Canadian bitumen production currently runs about 1 MMbpd, with some being sold as Synbit and Dilbit. Over the next 10-12 years output is expected to increase to 3.5 MMbpd and more refiners will begin investing to process it and come to depend on the Synbit and Dilbit for a significant part of their supply. Few today, however, have ever processed these feeds at high blend ratios, and are unaware that conventional process and equipment designs are not up to the job. Canadian oil ...

Are you ready for MARPOL?

As the International Maritime Organization (IMO) has decided to implement the MARPOL Annex VI, all ships must globally reduce their emissions of sulfur by 86% before 2020. This fact is bound to have a huge impact on the shipping as well as the refinery industry. But exactly what will happen? What options are there? What are the opportunities? Who will seize them? And how?   The MARPOL directive presents great opportunities for refineries. Whether you want to produce MARPOL ...
