The existing liquid in/out nozzle, drain pipelines needs to be modified suitably. The job of modification shall be executed on LSTK basis which includes, design, supply, fabrication, installation, and testing, commissioning assistance to Client and obtaining necessary statutory approvals.
The work has been carried out to provide smooth operation of “reactor-regenerator” system as an important step in the problem of synthetic detergents production efficiency enhancing. Reasons which cause violation of HF-catalyst regeneration column regime have been identified. The ways of benzene alkylation rector and catalyst regenerator
The work has been carried out to provide smooth operation of “reactor-regenerator” system as an important step in the problem of synthetic detergents production efficiency enhancing. Reasons which cause violation of HF-catalyst regeneration column regime have been identified. The ways of benzene alkylation rector and catalyst regenerator column joint work optimization have been proposed. Optimization consists of HF-catalyst optimal activity achievement with further system conversion in to the steady state, as well as probable failure date predicting with the possibility of column drainage in order to prevent it. The concept of the optimal activity has been introduced and positive effect achieved by its maintaining has been shown.
Shop fabrication is, generally speaking, any pipe, fittings and components that are assembled by welding into spool assemblies at the fabricator's facility. ... These are welded joints that connect the pre-fabricated spools. In doing this the designer or fabricator will identify two different types of field-welded joints.
