The present technology is generally directed to systems and methods for improving quenched coke recovery. More specifically, some embodiments are directed to systems and methods utilizing one or more of a screen, barrier, or reflector panel to contain or redirect coke during or after quenching. In a particular embodiment, a quench car system for containing coke includes a quench car having a base, a plurality of sidewalls, and a top portion. The system can further include a permeable barrier covering at least a portion of the top of the quench car, wherein the permeable barrier has a plurality of apertures therethrough.

A method for manufacturing a natural pesticide and a water quenching device thereof are provided. The method includes the steps of: burning paddy at a high temperature of 400-900 C. into carbonized paddy, wherein the carbonized paddy comprises at least 50% silica, at least 10% organic matter, at least 2% potassium, and at most 2% water; using a water quenching device to quench and heat the carbonized paddy, enabling the carbonized paddy to form a gas and a solid substance by means of solid-liquid separation; using the water quenching device to condense the gas separated from the carbonized paddy into a liquid; and testing a PH value of the liquid after condensation through the water quenching device, wherein when the PH value of the liquid is alkaline, the liquid is outputted and stored as a pesticide.

The present disclosure relates to a process for the production of needle coke in a delayed coker plant. The needle coke so obtained by the process of the present disclosure has a co-efficient of thermal expansion (CTE) of less than 1.210.sup.6/ C. The process of the present disclosure eliminates the step of hydrotreating of the first feed and second feed for the production of good quality coke. The process of the present disclosure maximizes the production of the needle coke having low CTE and low sulfur content in the delayed coker coke drum.
