Becht Engineering has senior process specialists covering all refining and many petrochemical and chemical processes. These include alkylation (HF and sulfuric), aromatics recovery and purification, olefins production and polymer feed pretreatment, catalytic cracking, delayed coking, fluid coking, flexicoking, gas treating, hydrotreating, hydrocrac
king, reforming including CCR, lubes, sulfur recovery, sour water treating, product and water treatment.
Becht also has specialists in the chemical engineering technology disciplines such as crude oil characterization, mixing, heat transfer, fractionation and separations.
Mentoring Young Process Engineers
Saturday, 04 June 2016
Arve B. Holt
Today’s young process engineers have tools available to them that we “old timers” only dreamed about. Although smaller and some medium sized companies will not have the items listed below, most large refining and or petrochemical operations have the following: Real-time and historical plant operating data available on his/her desk top computers; Real-time and historical plant laboratory data available on his/her desk top computer; Access to the plant DCS control schematics showing current operating details (though no ability to change set points, etc.); Access to powerful process simulation software; Up-to-date (mostly) P&ID’s and unit piping/structural drawings available with the click of a mouse. The list of available resources to today’s younger process engineer without leaving his or her office goes on and on. Couple this with the trend to large centralized control rooms for safety and efficiency reasons and you easily end up with one large negative to all this progress....

PSM Implementation is a Challenge -- Maintaining Compliance is Even Harder
Tuesday, 12 April 2016
The Process Safety Management rule (PSM), OSHA 1910.119, was implemented in the early 90’s, more than 20 years ago. Implementation was driven by a number of tragic accidents in the process industry. However, despite the long history of the rule and multiple preventable, catastrophic incidents, many companies still have not fully implemented PSM. Companies that have implemented the PSM rule often find it very challenging to maintain compliance. Becht Engineering has conducted numerous PSM, due diligence and mechanical integrity audits and discovered deficiencies in PSM compliance. We have even discovered major gaps in some facilities that have done well during OSHA audits. These plants were generally located where there are limited numbers of hydrocarbon and chemical processing facilities. OSHA simply lacked the local resources and skills to perform adequate audits. These plants can be highly vulnerable to both incidents and fines since they may assume everything is in compliance. In the...

Demister Pads—A simple device until they don’t work
Monday, 22 July 2013
A demister pad is similar to an air filter except instead of removing dust particles from a stream of air for example, it removes micron-size liquid particles from a liquid/vapor stream often found in many industrial processes. An air filter prevents dust particles from entering downstream equipment; similarly a demister prevents liquid droplets from entering downstream equipment where they may affect operation or cause damage. In general, a duty specification is prepared by the process designer and given to demister vendors to recommend a demister that meets the duty requirements. Or today, knowing the required duty you can select a demister from the vendor's online catalog. The demister is installed, performs as intended and is never heard about again. On occasion, problems arise as the case in which Bob Fiocco, a Becht Sr. Advisor, provided technical support to a refining client on demister design and selection. An existing demister installed in...
